I like charts, mostly pie but also bar, and I really like shades of grey best - for normal purposes physically printing is just black‑and‑white (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 background‑image 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.

thick
		left		right
thin

It be easiest to make just one colour :

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.
