I like charts, mostly pie but also bar, and I really like shades of grey best - for normal purposes physically printing is just blackandwhite (and shades of grey). But this really allow only ten shades of grey. I would like just a few options to make up to 15-ish. I think to extend to texture would do the trick. And I see that these days CSS backgroundimage can be specified. These are lots of different things can be made, but for use here I would just what two textures, and just left top to right bottom or the other way, and narrow chevron or wider.

So Frietjes, I won't if you could help. I want to enhance module:chart (bar and pie). The module have been written by the user-with-a-Hebrew-name, s/he doesn't seem to be online very often. It seems easy enough, but the module code is a closed book as far as I can see. Do you be able to help?

Just all one or two colours, with direction 'left' or 'right', and 'thin' or 'thick'. I know this OK with IE, I don't know any browser.
