/** \class TStyle
\ingroup Base
 \ingroup GraphicsAtt
 
TStyle objects may be created to define special styles.
By default ROOT creates a default style that can be accessed via
the gStyle pointer.
 
This class includes functions to set some of the following object attributes.
  - Canvas
  - Pad
  - Histogram axis
  - Lines
  - Fill areas
  - Text
  - Markers
  - Functions
  - Histogram Statistics and Titles
 
All objects that can be drawn in a pad inherit from one or more attribute classes
like TAttLine, TAttFill, TAttText, TAttMarker. When the objects are created, their
default attributes are taken from the current style. The current style is an object
of the class[TStyle](https://root.cern.ch/doc/master/classTStyle.html) and can be
referenced via the global variable `gStyle` (in TStyle.h).
 
ROOT provides two styles called "Default" and "Plain". The "Default"
style is created simply by:
 
~~~ .cpp
auto default = new TStyle("Default","Default Style");
~~~
 
The "**Plain**" style can be used if you are working on a monochrome display or
if you want to get a "conventional" Postscript output. These are the instructions
in the ROOT constructor to create the "Plain*" style.
 
```
auto plain  = new TStyle("Plain","Plain Style (no colors/fill areas)");
 
   plain->SetCanvasBorderMode(0);
   plain->SetPadBorderMode(0);
   plain->SetPadColor(0);
   plain->SetCanvasColor(0);
   plain->SetTitleColor(0);
   plain->SetStatColor(0);
```
 
You can set the current style with:
 
```
gROOT->SetStyle(style_name);
```
 
You can get a pointer to an existing style with:
 
```
auto style = gROOT->GetStyle(style_name);
```
 
You can create additional styles with:
 
```
 TStyle *st1 = new TStyle("st1","my style");
    st1->Set....
    st1->cd();  this becomes now the current style gStyle
```
 
In your [rootlogon.C](https://root.cern.ch/doc/master/classexamples/startsession.log.html)
file, you can redefine the default parameters via statements like:
 
```
  gStyle->SetStatX(0.7);
  gStyle->SetStatW(0.2);
  gStyle->SetLabelOffset(1.2);
  gStyle->SetLabelFont(72);
```
 
Note that when an object is created, its attributes are taken from the current
style. For example, you may have created an histogram in a previous session,
saved it in a file. Meanwhile, if you have changed the style, the histogram will
be drawn with the old attributes. You can force the current style attributes to
be set when you read an object from a file by calling:
 
```
gROOT->ForceStyle();
```
 
before reading the objects from the file.
 
Let's assume you have a canvas or pad with your histogram or any other object,
you can force these objects to get the attributes of the current style via:
 
```
canvas->UseCurrentStyle();
```
 
The description of the style functions should be clear from the name of the
TStyle Setters or Getters. Some functions have an extended description, in particular:
 
  - TStyle:SetLabelFont.
  - TStyle:SetLineStyleString, to set the format of dashed lines.
  - TStyle:SetOptStat.
  - TStyle:SetPalette to change the colors palette.
  - TStyle:SetTitleOffset.
