Hi, I've got two sets of data I'm displaying in a bar graph. I'd like to use two different colors for the different data. I'm not sure how to do this. My code looks like: @xdata1; # bunch of x values @ydata1; # bunch of corresponding y values @xdata2; # second set of x values I'd like to plot @ydata2; # second set of y values
I have to admit that I have never used GD::Graph before. However, something about what you are describing does not seem right. A bar graph doesn't usually have two sets of x-values. Just to clarify so that maybe someone else can help you, is this what you meant. Suppose you have heights of men and women for a set of age groups: 0-15 years, 16-21 years, 22-30 years, 30 and up [not to indicate life goes downhill from 30, but just to save me typing :-) ]. That means, for both men and women, you have 4 y-values each. In order to compare men and women that are 0-15 years old, their x-values need to be the same. [Actually, in this example, there are 4 bars each, and the x-values could just be discrete values like "0, 1, 2, 3".] Somewhat of a trivial example, but can you change this example to what you are trying to do? I'm just wondering whether or not a bar graph or even two graphs in a plot, is the tool you want...
