TSpectrum2Painter Class Reference

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.

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,

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.

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;

◆ 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
