adding designs to the colors available for the graphs (Read 593 times)

Would it be possible to add in designs to the colors available for different workout types. By designs I mean intead of a solid color (red for instance) have something with little dots or diaganal lines, nothing fancy just something to differentiate between some of the colors. I know this can be done in excell, but I don't know if it can be done here. This is probably not a big deal for most folks, but I am color blind and there are only so many colors that I can actually tell the difference between without giving myself a headache and I'm still wrong about half the time.
