The palette painting class.
A TPaletteAxis
object is used to display the color palette when drawing 2-d histograms.
The TPaletteAxis
is automatically created drawn when drawing a 2-D histogram when the option "Z" is specified.
A TPaletteAxis
object is added to the histogram list of functions and can be retrieved doing:
TPaletteAxis *palette = (TPaletteAxis*)h->GetListOfFunctions()->FindObject("palette");
then the pointer palette
can be used to change the palette attributes.
Because the palette is created at painting time only, one must issue a:
gPad->Update();
before retrieving the palette pointer in order to create the palette. The following macro gives an example.
TPaletteAxis
inherits from TBox
and TPave
. The methods allowing to specify the palette position are inherited from these two classes.
The palette can be interactively moved and resized. The context menu can be used to set the axis attributes.
It is possible to select a range on the axis to set the min/max in z
As default labels and ticks are drawn by TGAxis
at equidistant (lin or log) points as controlled by SetNdivisions. If option "CJUST" is given labels and ticks are justified at the color boundaries defined by the contour levels. In this case no optimization can be done. It is responsibility of the user to adjust minimum, maximum of the histogram and/or the contour levels to get a reasonable look of the plot. Only overlap of the labels is avoided if too many contour levels are used.
This option is especially useful with user defined contours. An example is shown here:
