Legacy Code

TSpectrum2Painter is a legacy interface: there will be no bug fixes nor new developments. Therefore it is not recommended to use it in new long-term production code. But, depending on the context, using TSpectrum2Painter might still be a valid solution.

Two-dimensional graphics function

TSpectrum2Painter is a set of graphical functions developed by Miroslav Morhac to paint 2D-histograms in three dimensions. This package is accessed via THistPainter in a transparent way. For the ROOT user it is enough to use the "SPEC" option to draw a 2D-Histogram. This option offers many functionalities detailed in the header of the PaintSpectrum function.

◆ anonymous enum

anonymous enum

Enumerator
kOnlyPrepStep 

Used to request that the class specific implementation of TObject::Write just prepare the objects to be ready to be written but do not actually write them into the TBuffer.

This is just for example by TBufferMerger to request that the TTree inside the file calls TTree::FlushBaskets (outside of the merging lock) and TBufferMerger will later ask for the write (inside the merging lock). To take advantage of this feature the class needs to overload TObject::Write and use this enum value accordingly. (See TTree::Write and TObject::Write) Do not use, this feature will be migrate to the Merge function (See TClass and TTree::Merge)

Member Function Documentation

◆ AbstractMethod()

void TObject::AbstractMethod ( const char * method) const
inherited

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.

In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Warning
This interface is a legacy function that is no longer recommended to be used by new development code.
Note
The name "AbstractMethod" does not imply that it's an abstract method in the strict C++ sense.

◆ CheckedHash()

ULong_t TObject::CheckedHash ( )
inlineinherited

Check and record whether this class has a consistent Hash/RecursiveRemove setup (*) and then return the regular Hash value for this object.

The intent is for this routine to be called instead of directly calling the function Hash during "insert" operations. See TObject::HasInconsistenTObjectHash();

(*) The setup is consistent when all classes in the class hierarchy that overload TObject::Hash do call ROOT::CallRecursiveRemoveIfNeeded in their destructor. i.e. it is safe to call the Hash virtual function during the RecursiveRemove operation.

Return true is the type of this object is known to have an inconsistent setup for Hash and RecursiveRemove (i.e.

missing call to RecursiveRemove in destructor).

Note: Since the consistency is only tested for during inserts, this routine will return true for object that have never been inserted whether or not they have a consistent setup. This has no negative side-effect as searching for the object with the right or wrong Hash will always yield a not-found answer (Since anyway no hash can be guaranteed unique, there is always a check)

Visualization

Goal: to present 2-dimensional spectra in suitable visual form

This package has several display mode groups and display modes, which can be employed for the presentation of 2-dimensional histograms

Display modes groups:

  • kModeGroupSimple - it covers simple display modes using one color only
  • kModeGroupLight - in this group the shading is carried out according to the position of the fictive light source
  • kModeGroupHeight - in this group the shading is carried out according to the channel contents
  • kModeGroupLightHeight - combination of two previous shading algorithms. One can control the weight between both algorithms.

Display modes:

  • kDisplayModePoints,
  • kDisplayModeGrid,
  • kDisplayModeContours,
  • kDisplayModeBars,
  • kDisplayModeLinesX,
  • kDisplayModeLinesY,
  • kDisplayModeBarsX,
  • kDisplayModeBarsY,
  • kDisplayModeNeedles,
  • kDisplayModeSurface,
  • kDisplayModeTriangles.

one can combine the above given modes groups and display modes. The meaningful combinations (denoted by x) are given in the next table.

Function: TSpectrum2Painter::SetPenAttr(Int_t color,Int_t style,Int_t width)

Using this function one can change pen color, pen style and pen width. Possible pen styles are:

  • kPenStyleSolid,
  • kPenStyleDash,
  • kPenStyleDot,
  • kPenStyleDashDot.

Default values:

  • color = kBlack

  • width = 1

Simple modes group, display mode = linesX, 64 x 64 channels. Pen width = 3.

Function: TSpectrum2Painter::SetNodes(Int_t nodesx,Int_t nodesy)

Sometimes the displayed region is rather large. When displaying all channels pictures become very dense and complicated. It is very difficult to understand overall shape of the data. Therefore in the package we have implemented the possibility to change the density of displayed channels. Only channels coinciding with given nodes are displayed. In the next figure we introduce the example of the above presented spectrum with number of nodes set to 64x64.

Default values:

  • nodesx = Xmax-Xmin+1
  • nodesy = Ymax-Ymin+1

Function: void TSpectrum2Painter::SetAngles (Int_t alpha,Int_t beta, Int_t view)

One can change the angles of the position of 3-d space and to rotate the space. Alpha parameter defines the angle between bottom horizontal screen line and the displayed space on the right side of the picture and beta on the left side, respectively. One can rotate the 3-d space around vertical axis going through the center of it employing the view parameter. Allowed values are 0, 90, 180 and 270 degrees respectively.

Default values:

  • scale = kZScaleLinear

Height modes group, display mode = surface, 64 x 64 channels, log scale.

Function: TSpectrum2Painter::SetColorIncrements(Double_t r,Double_t g,Double_t b);

For sophisticated shading (in kModeGroupLight, kModeGroupHeight and kModeGroupLightHeight display modes groups) the color palette starts from the basic pen color (see SetPenAttr function). There is a predefined number of color levels (256). Color in every level is calculated by adding the increments of the r, g, b components to the previous level. Using this function one can change the color increments between two neighbouring color levels. The function does not apply for kModeGroupSimple display modes group. Default values: r=1, g=1, b=1;

Light modes group, display mode = surface, 64 x 64 channels, color increments r=1, g=2, b=3.

Light modes group, display mode = surface, 64 x 64 channels, color increments r=4, g=2, b=1.

Function: TSpectrum2Painter::SetColorAlgorithm(Int_t colorAlgorithm)

To define the colors one can employ one of the following color algorithms (rgb, cmy, cie, yiq, hvs models [1], [2]). When the level of a component achieves the limit value one can choose either smooth transition (by decreasing the limit value) or sharp - modulo transition (continuing with 0 value). This makes possible to realize various visual effects. One can choose from the following set of the algorithms:

  • kColorAlgRgbSmooth
  • kColorAlgRgbModulo
  • kColorAlgCmySmooth
  • kColorAlgCmyModulo
  • kColorAlgCieSmooth
  • kColorAlgCieModulo
  • kColorAlgYiqSmooth
  • kColorAlgYiqModulo

  • kColorAlgHvsModulo

The function does not apply for kModeGroupSimple display modes group. Default value is:

  • colorAlgorithm = kColorAlgRgbSmooth

Function: TSpectrum2Painter::SetLightPosition(Int_t x, Int_t y, Int_t z)

In kModeGroupLight and kModeGroupLightHeight display modes groups the color palette is calculated according to the fictive light source position in 3-d space. Using this function one can change the position of the source and thus to achieve various graphical effects. The function does not apply for kModeGroupSimple and kModeGroupHeight display modes groups. Default values are: x=1000, y=1000, z=1000.

Light modes group, display mode = surface, 64 x 64 channels. Position of the light source was set to x=0, y=1000, z=1000.

Function: TSpectrum2Painter::SetShading(Int_t shading,Int_t shadow)

Surface of the picture is composed of triangles. If desired the edges of the neighbouring triangles can be smoothed (shaded). If desired the display of the shadow can be painted as well. The function does not apply for kModeGroupSimple display modes group.

  • kNotShaded
  • kShaded.

Possible values for shadow are:

  • kShadowsNotPainted
  • kShadowsPainted

Default values:

  • shading = kShaded
  • shadow = kShadowsNotPainted

◆ PaintSpectrum()

void TSpectrum2Painter::PaintSpectrum ( TH2 * h2,
Option_t * option = "",
Int_t bs = 1600 )
static

This function allows to set all the possible options available in TSpectrum2Painter and paint "h2".

TSpectrum2Painter offers a large set of options/attributes. In the "option" parameter each of them can be set to specific values via "operators" in the option itself. for instance on can do: 

h2->Draw("SPEC a(30,30,0)");

to draw h2 with TSpectrum2Painter using all the default attributes except the viewing angles. The operators' names are case insensitive (one can use "a" or "A"). Operators parameters are separated by ",". The operators can be put is any order in the option. Operators must be separated by " ". No " " characters should be put in an operator. This help page describes all the available operators.

The way "h2" will be painted is controlled with 2 parameters the "Display modes groups" and the "Display Modes".

"Display modes groups" can take the following values:

  • 0 = Simple - it covers simple display modes using one color only
  • 1 = Light - in this group the shading is carried out according to the position of the fictive light source
  • 2 = Height - in this group the shading is carried out according to the channel contents
  • 3 = LightHeight - combination of two previous shading algorithms. One can control the weight between both algorithms.

"Display modes" can take the following values:

  • 1 = Points.
  • 2 = Grid.
  • 3 = Contours.
  • 4 = Bars.
  • 5 = LinesX.
  • 6 = LinesY.
  • 7 = BarsX.
  • 8 = BarsY.
  • 9 = Needles.
  • 10 = Surface.
  • 11 = Triangles.

Using this function these parameters can be set using the "dm" operator in the option. Example: 

h2->Draw("SPEC dm(1,2)");

will paint the 2D histogram h2 using the "Light Display mode group" and the "Grid Display mode". The following table summarises all the possible combinations of the "Display modes groups" and the "Display modes".

Simple Light Height Light-Height
Points X X X X
Grid X X X X
Contours X - X -
Bars X - X -
LinesX X X X X
LinesY X X X X
BarsX X - X -
BarsY X - X -
Needles X - - -
Surface - X X X
Triangles X X X X

The Pen Attributes can be changed using pa(color, style, width). Example: 

h2->Draw("SPEC dm(1,2) pa(2,1,2)");

sets the line color to 2, line type to 1 and line width to2. Note that if pa() is not specified, the histogram "h2" line attributes are used. Note also that operators for SPEC option can be cumulated and specified in any order.

The buffer size can be change with bf(size). Example: 

h2->Draw("SPEC bf(8000)");

The spectrum painter needs a buffer to paint the spectrum. By default the buffer size is set to 1600. In most cases this buffer size is enough. But if the canvas size is very big, for instance 8000x5000 this buffer size is too small. An error message is issued telling to use the option bf().

The number of nodes can be change with n(nodesx, nodesy). Example: 

h2->Draw("SPEC n(40,40)");

Sometimes the displayed region is rather large. When displaying all channels pictures become very dense and complicated. It is very difficult to understand the overall shape of data. "n(nx,ny)" allows to change the density of displayed channels. Only the channels coinciding with given nodes are displayed.

The visualization angles can be changed with a(alpha, beta, view). Example: 

h2->Draw("SPEC n(40,40) dm(0,1) a(30,30,0)");

Alpha defines the angle between bottom horizontal screen line and the displayed space on the right side of the picture and beta on the left side, respectively. One can rotate the 3-d space around vertical axis going through the center of it employing the view parameter. Allowed values are 0, 90, 180 and 270 degrees.

zs(scale) changes the scale of the Z-axis Possible values are:

  • 0 = Linear (default)
  • 1 = Log
  • 2 = Sqrt

If gPad->SetLogz() has been set, log scale on Z-axis is set automatically. No need to use the zs() operator. Note that the X and Y axis are always linear.

ci(r,g,b), were r,g and b are floats defines the colors increments. For sophisticated shading (Light, Height and LightHeight Display Modes Groups) the color palette starts from the basic pen color (see pa() function). There is a predefined number of color levels (256). Color in every level is calculated by adding the increments of the r, g, b components to the previous level. Using this function one can change the color increments between two neighbouring color levels. The function does not apply dor the Simple Display Modes Group. The default values are: (1,1,1).

ca(color_algorithm) allows to choose the Color Algorithm. To define the colors one can employ one of the following color algorithms (RGB, CMY, CIE, YIQ, HVS models). When the level of a component reaches the limit value one can choose either smooth transition (by decreasing the limit value) or a sharp modulo transition (continuing with 0 value). This makes possible to realize various visual effects. One can choose from the following set of the algorithms:

  • 0 = RGB Smooth
  • 1 = RGB Modulo
  • 2 = CMY Smooth
  • 3 = CMY Modulo
  • 4 = CIE Smooth
  • 5 = CIE Modulo
  • 6 = YIQ Smooth
  • 7 = YIQ Modulo
  • 8 = HVS Smooth
  • 9 = HVS Modulo

This function does not apply on Simple display modes group. Default value is 0. Example: 

h2->Draw("SPEC c1(4) dm(0,1) a(30,30,0)");

choose CMY Modulo to paint the "h2" histogram.

lp(x,y,z) set the light position. In Light and LightHeight display modes groups the color palette is calculated according to the fictive light source position in 3-d space. Using this function one can change the position of the source and thus to achieve various graphical effects. This function does not apply for Simple and Height display modes groups. Default is: lp(1000,1000,100).

s(shading,shadow) allows to set the shading. The picture's surface is composed of triangles. If desired the edges of the neighbouring triangles can be smoothed (shaded). If desired the display of the shadow can be painted as well. The function does not apply for Simple display modes group. The possible values for shading are:

  • 0 = Not Shaded
  • 1 = Shaded

The possible values for shadow are:

  • 0 = Shadows are not painted
  • 1 = Shadows are painted

Default values: s(1,0)

b(bezier) set the Bezier smoothing. For Simple display modes group and for Grid, LinesX and LinesY display modes one can smooth data using Bezier smoothing algorithm. The function does not apply for other display modes groups and display modes. Possible values are:

  • 0 = No bezier smoothing
  • 1 = Bezier smoothing

Default value is: b(0)

cw(width) set the contour width. This function applies only for the Contours display mode. One can change the width between horizontal slices and thus their density. Default value: cw(50)

lhw(weight) set the light height weight. For LightHeight display modes group one can change the weight between both shading algorithms. The function does not apply for other display modes groups. Default value is lhw(0.5).

cm(enable,color,width,height,style) allows to draw a marker on each node. In addition to the surface drawn using any above given algorithm one can display channel marks. One can control the color as well as the width, height (in pixels) and the style of the marks. The parameter enable can be set to

  • 0 = Channel marks are not drawn
  • 1 = Channel marks drawn

The possible styles can be chosen from the set:

  • 1 = Dot
  • 2 = Cross
  • 3 = Star
  • 4 = Rectangle
  • 5 = X
  • 6 = Diamond
  • 7 = Triangle.

cg(enable,color) channel grid. In addition to the surface drawn using any above given algorithm one can display grid using the color parameter. The parameter enable can be set to:

  • 0 = Grid not drawn
  • 1 = Grid drawn

◆ Write() [2/2]

Int_t TObject::Write ( const char * name = nullptr,
Int_t option = 0,
Int_t bufsize = 0 ) const
virtualinherited

Write this object to the current directory.

The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".

Writing an object to a file involves the following steps:

  • Creation of a support TKey object in the current directory. The TKey object creates a TBuffer object.
  • The TBuffer object is filled via the class::Streamer function.
  • If the file is compressed (default) a second buffer is created to hold the compressed buffer.
  • Reservation of the corresponding space in the file by looking in the TFree list of free blocks of the file.
  • The buffer is written to the file.

Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.

If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().

The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.

An object is read from the file into memory via TKey::Read() or via TObject::Read().

The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.

Reimplemented in TBuffer, TCollection, TDirectory, TDirectoryFile, TFile, TMap, TParallelMergingFile, TSQLFile, TTree, and TXMLFile.
