I am trying to do the same thing with a TMultiGraph. (the macro file attached, the data file is attached to my other mail)
Reading my data from the file is OK, and even they are drawn.
However, not quite so as I want.
1./ I do not see the markers, only some dots, even if I set the marker size differently.
2./ Again, is there another method to disable line drawing, or only to set the line color to the canvas fill color?
3./ The markers are not displayed in the TLegend.
4./ The vertical scale is normalized correctly, but I cannot change it. The SetRangeUser dialog appears, accepts my new values but nothing happens.
5./ If I try the logarithmic Y scale, I receive the message “Error in THistPainter::PaintInit: log scale requested with zero or negative argument (0.000000)” and the graph goes to the bottom.
6./ The log X scale option seems to work, but
a) it switches X grid off
b) the X scale disappears
Do I wrong something?
