ROOT 6.18/05 Reference Guide |
The most important graphics class in the ROOT system.
A Pad is contained in a Canvas.
A Pad may contain other pads (unlimited pad hierarchy).
A pad is a linked list of primitives of any type (graphics objects, histograms, detectors, tracks, etc.).
Adding a new element into a pad is in general performed by the Draw member function of the object classes.
It is important to realize that the pad is a linked list of references to the original object. For example, in case of a histogram, the histogram.Draw() operation only stores a reference to the histogram object and not a graphical representation of this histogram. When the mouse is used to change (say the bin content), the bin content of the original histogram is changed.
The convention used in ROOT is that a Draw operation only adds a reference to the object. The effective drawing is performed when the canvas receives a signal to be painted.
This signal is generally sent when typing carriage return in the command input or when a graphical operation has been performed on one of the pads of this canvas. When a Canvas/Pad is repainted, the member function Paint for all objects in the Pad linked list is invoked.
When the mouse is moved on the Pad, The member function DistancetoPrimitive is called for all the elements in the pad. DistancetoPrimitive returns the distance in pixels to this object.
When the object is within the distance window, the member function ExecuteEvent is called for this object.
In ExecuteEvent, move, changes can be performed on the object.
For examples of DistancetoPrimitive and ExecuteEvent functions, see classes
A Pad supports linear and log scales coordinate systems. The transformation coefficients are explained in TPad::ResizePad.

Pad constructor.
A pad is a linked list of primitives. A pad is contained in a canvas. It may contain other pads. A pad has attributes. When a pad is created, the attributes defined in the current style are copied to the pad attributes.
[in] | name | pad name |
[in] | title | pad title |
[in] | xlow | [0,1] is the position of the bottom left point of the pad expressed in the mother pad reference system |
[in] | ylow | [0,1] is the Y position of this point. |
[in] | xup | [0,1] is the x position of the top right point of the pad expressed in the mother pad reference system |
[in] | yup | [0,1] is the Y position of this point. |

Add a new TExec object to the list of Execs.
When an event occurs in the pad (mouse click, etc) the list of C++ commands in the list of Execs are executed via TPad::AutoExec.
When a pad event occurs (mouse move, click, etc) all the commands contained in the fExecs list are executed in the order found in the list.
This facility is activated by default. It can be deactivated by using the canvas "Option" menu.
The following examples of TExec commands are provided in the tutorials: macros exec1.C and exec2.C.
At this point you can use the mouse to click on the contour of the histogram hpx. When the mouse is clicked, the bin number and its contents are printed.
When moving the mouse in the canvas, a second canvas shows the projection along X of the bin corresponding to the Y position of the mouse. The resulting histogram is fitted with a gaussian. A "dynamic" line shows the current bin position in Y. This more elaborated example can be used as a starting point to develop more powerful interactive applications exploiting the C++ interpreter as a development engine.

Build a legend from the graphical objects in the pad.
A simple method to build automatically a TLegend from the primitives in a TPad.
Only those deriving from TAttLine, TAttMarker and TAttFill are added, excluding TPave and TFrame derived classes.
[in] | x1,y1,x2,y2 | The TLegend coordinates |
[in] | title | The legend title. By default it is " " |
[in] | option | The TLegend option |
The caller program owns the returned TLegend.
If the pad contains some TMultiGraph or THStack the individual graphs or histograms in them are added to the TLegend.
If x1
is equal to x2
and y1
is equal to y2
the legend will be automatically placed to avoid overlapping with the existing primitives already displayed. x1
is considered as the width of the legend and y1
the height. By default the legend is automatically placed with width = x1
= x2
= 0.3 and height = y1
= y2
= 0.21.

Set Current pad.
When a canvas/pad is divided via TPad::Divide, one can directly set the current path to one of the subdivisions. See TPad::Divide for the convention to number sub-pads.
Returns the new current pad, or 0 in case of failure.
For example:
To set the current pad to the bottom right pad, do
Note1: c1.cd() is equivalent to c1.cd(0) and sets the current pad to c1 itself.
Note2: after a statement like c1.cd(6), the global variable gPad points to the current pad. One can use gPad to set attributes of the current pad.
Note3: One can get a pointer to one of the sub-pads of pad with: TPad subpad = (TPad)pad->GetPad(subpadnumber);

[in] | xclipl,yclipb,xclipr,yclipt | Clipping boundary |
[out] | nn | Number of points in xc and yc |
[out] | xc,yc | Clipped polygon vertices. The Int_t returned by this function is the number of points in the clipped polygon. These vectors must be allocated by the calling function. A size of 2*n for each is enough. |
Sutherland and Hodgman's polygon-clipping algorithm uses a divide-and-conquer strategy: It solves a series of simple and identical problems that, when combined, solve the overall problem. The simple problem is to clip a polygon against a single infinite clip edge. Four clip edges, each defining one boundary of the clip rectangle, successively clip a polygon against a clip rectangle.
Steps of Sutherland-Hodgman's polygon-clipping algorithm:
The clip boundary determines a visible and invisible region. The edges from vertex i to vertex i+1 can be one of four types:

Automatic pad generation by division.
Pads are automatically named canvasname_n
where n
is the division number starting from top left pad.
Example if canvasname=c1 , nx=2, ny=3:
Once a pad is divided into sub-pads, one can set the current pad to a subpad with a given division number as illustrated above with TPad::cd(subpad_number).
For example, to set the current pad to c1_4, one can do:
Note1: c1.cd() is equivalent to c1.cd(0) and sets the current pad to c1 itself.
Note2: after a statement like c1.cd(6), the global variable gPad points to the current pad. One can use gPad to set attributes of the current pad.
Note3: in case xmargin <=0 and ymargin <= 0, there is no space between pads. The current pad margins are recomputed to optimize the layout.

Execute action corresponding to one event.
This member function is called when a TPad object is clicked.
If the mouse is clicked in one of the 4 corners of the pad (pA,pB,pC,pD) the pad is resized with the rubber rectangle.
If the mouse is clicked inside the pad, the pad is moved.
If the mouse is clicked on the 4 edges (pL,pR,pTop,pBot), the pad is scaled parallel to this edge.
Note that this function duplicates on purpose the functionality already implemented in TBox::ExecuteEvent. If somebody modifies this function, may be similar changes should also be applied to TBox::ExecuteEvent.

Execute action corresponding to one event for a TAxis object (called by TAxis::ExecuteEvent.) This member function is called when an axis is clicked with the locator.
The axis range is set between the position where the mouse is pressed and the position where it is released.
If the mouse position is outside the current axis range when it is released the axis is unzoomed with the corresponding proportions.
Note that the mouse does not need to be in the pad or even canvas when it is released.

Save Canvas contents in a file in one of various formats.
option can be:
"root" a ROOT binary file
filename = 0 - filename is defined by the GetName and its extension is defined with the option
When Postscript output is selected (ps, eps), the canvas is saved to filename.ps or filename.eps. The aspect ratio of the canvas is preserved on the Postscript file. When the "ps" option is selected, the Postscript page will be landscape format if the canvas is in landscape format, otherwise portrait format is selected.
The physical size of the Postscript page is the one selected in the current style. This size can be modified via TStyle::SetPaperSize.
Examples:
where TStyle::kA4 and TStyle::kUSLetter are defined in the enum EPaperSize in TStyle.h
An alternative is to call:
The above numbers take into account some margins and are in centimeters.
The "Preview" option allows to generate a preview (in the TIFF format) within the Encapsulated Postscript file. This preview can be used by programs like MSWord to visualize the picture on screen. The "Preview" option relies on the "epstool" command (http://www.cs.wisc.edu/~ghost/gsview/epstool.htm).
Example:
The "EmbedFonts" option allows to embed the fonts used in a PDF file inside that file. This option relies on the "gs" command (https://ghostscript.com).
Example:
Example:
In the previous example replacing "ps" by "pdf" will create a multi-pages PDF file.
Note that the following sequence writes the canvas to "c1.ps" and closes the ps file.:
The TCanvas::Print("file.ps(") mechanism is very useful, but it can be a little inconvenient to have the action of opening/closing a file being atomic with printing a page. Particularly if pages are being generated in some loop one needs to detect the special cases of first and last page and then munge the argument to Print() accordingly.
The "[" and "]" can be used instead of "(" and ")".
Example:
As before, the same macro is valid for PDF files.
It is possible to print a canvas into an animated GIF file by specifying the file name as "myfile.gif+" or "myfile.gif+NN", where NN*10ms is delay between the subimages' display. If NN is omitted the delay between subimages is zero. Each picture is added in the animation thanks to a loop similar to the following one:
The delay between each frame must be specified in each Print() statement. If the file "myfile.gif" already exists, the new frame are appended at the end of the file. To avoid this, delete it first with gSystem->Unlink(myfile.gif); If you want the gif file to repeat or loop forever, check TASImage::WriteImage documentation

Redraw the frame axis Redrawing axis may be necessary in case of superimposed histograms when one or more histograms have a fill color Instead of calling this function, it may be more convenient to call directly h1->Draw("sameaxis") where h1 is the pointer to the first histogram drawn in the pad.
By default, if the pad has the options gridx or/and gridy activated, the grid is not drawn by this function. if option="g" is specified, this will force the drawing of the grid on top of the picture

\[\frac{x-xmin}{xrange} = \frac{px-pxlow}{pxrange}\]
with:
\[ xrange = xmax-xmin \]
\[ pxrange = pxmax-pxmin \]
\[ \Rightarrow px = \frac{pxrange(x-xmin)}{xrange} + pxlow = fXtoPixelk + fXtoPixel \times x \]
\[ \Rightarrow fXtoPixelk = pxlow - pxrange \frac{xmin}{xrange} \]
\[ fXtoPixel = \frac{pxrange}{xrange} \]

\[ pxlow = fAbsXlowNDC \times fCw \]
\[ pxrange = fAbsWNDC \times fCw \]
\[\frac{y-ymin}{yrange} = \frac{py-pylow}{pyrange}\]

\[ pyrange = pymax-pymin \]
\[ \Rightarrow py = \frac{pyrange(y-xmin)}{yrange} + pylow = fYtoPixelk + fYtoPixel \times y \]

\[ fYtoPixel = \frac{pyrange}{yrange} \]
where:
\[ pylow = fAbsYlowNDC \times fCh \]
\[ pyrange = fAbsHNDC \times fCh \]
\[ \Rightarrow x = \frac{xrange(px-pxlow)}{pxrange}+ xmin = fPixeltoXk + fPixeltoX \times px \]
\[ \Rightarrow fPixeltoXk = xmin - pxlow \times\frac{xrange}{pxrange} \]
\[ fPixeltoX = \frac{xrange}{pxrange} \]
\[ \Rightarrow y = \frac{yrange(py-pylow)}{pyrange}+ ymin = fPixeltoYk + fPixeltoY \times py \]

\[ fPixeltoY = \frac{yrange}{pyrange} \]
\[ u = \frac{Log(x) - Log(xmin)}{Log(xmax) - Log(xmin)} = \frac{Log(x/xmin)}{Log(xmax/xmin)} = \frac{px - pxlow}{pxrange} \]
\[ \Rightarrow Log(\frac{x}{xmin}) = u \times Log(\frac{xmax}{xmin}) \]
\[ x = xmin \times e^{(u \times Log(\frac{xmax}{xmin})} \]
Let:
\[ alfa = \frac{Log(\frac{xmax}{xmin})}{fAbsWNDC} \]
\[ x = xmin \times e^{(-alfa \times pxlow)} + e^{(alfa \times px)} \]
\[ x = fPixeltoXk \times e^{(fPixeltoX \times px)} \]
\[ ==> fPixeltoXk = xmin \times e^{(-alfa*pxlow)} \]
\[ fPixeltoX = alfa \]
\[ v = \frac{Log(y) - Log(ymin)}{Log(ymax) - Log(ymin)} = \frac{Log(y/ymin)}{Log(ymax/ymin)} = \frac{py - pylow}{pyrange} \]
Let:
\[ beta = Log(\frac{ymax}{ymin}) \]
\[ Log(\frac{y}{ymin}) = beta \times pylow - beta \times py \]
\[ \frac{y}{ymin} = e^{(beta \times pylow - beta \times py)} \]
\[ y = ymin \times e^{(beta \times pylow)} \times e^{(-beta \times py)}\]

\[ fPixeltoYk = ymin \times e^{(beta \times pylow)} \]
\[ fPixeltoY = -beta \]
\[ px = pxlow + u*pxrange \]
\[ = pxlow + Log(x/xmin)/alfa \]
\[ = pxlow -Log(xmin)/alfa + Log(x)/alfa \]
\[ = fXtoPixelk + fXtoPixel*Log(x) \]
\[ \Rightarrow fXtoPixelk = pxlow -Log(xmin)/alfa \]
\[ \Rightarrow fXtoPixel = 1/alfa \]
\[ py = pylow - Log(y/ymin)/beta \]

Loop and sleep until a primitive with name=pname is found in the pad.
If emode is given, the editor is automatically set to emode, ie it is not required to have the editor control bar.
The possible values for emode are:
If emode is specified and it is not valid, "PolyLine" is assumed. If emode is not specified or ="", an attempt is to use pname[1...]
for example if pname="TArc", emode="Arc" will be assumed. When this function is called within a macro, the macro execution is suspended until a primitive corresponding to the arguments is found in the pad.
If CRTL/C is typed in the pad, the function returns 0.
While this function is executing, one can use the mouse, interact with the graphics pads, use the Inspector, Browser, TreeViewer, etc.
Examples:
The following macro waits for 10 primitives of any type to be created.
If ROOT runs in batch mode a call to this method does nothing.
