Re: Problem with color of the graph

[Roland Bock <box2OO6 eudoxos de>]

Dear Naveen,

I hope you don't mind that I answer this question via the mailing list.

The "standard" graph classes of gtkdatabox only have one color per 
graph. I can currently think of two options of having different colors 
in different value ranges:

a) you define your own graph class to do this, with functions like 
my_graph_set_ranges_and_colors(...)

b) you use more than one graph. The additional graphs do not get the 
same amount of data, but only the data for the specific values that you 
want to color in a different way.

Option a) takes a bit more initial programming, but in the long run it 
pays, I think. Once the new graph class is in place, it is easier to use 
than several graphs and also the performance would be better, in most cases.


Regards,

Roland
