Background Colour Changes

[Shredivan]

Hi, I was wondering is their a way to change background colours? We're doing a chart for our app which is colour coded and have yet to find a way to implement the coloured backgrounds in our designs.

Thanks,
Dave

What you mean by background color? UIView already has it. of course you can override drawRect to fill the color you want I guess

Sorry i should have been more specific, I meant to colour of the background of the graph itself not the data been on it. I've attached an image to show you what I mean.

alright, if you are talking about the screenshot, it requires a lot of customization...
But it should not be hard:
the whole rect is defined as contentRect, so the bounding coordinates is known;
You first figure out, how many rects there and what's the sub rect frame value; and then you simply set the color and render it like

CGContextSetFillColorWithColor(context, subRectColor.CGColor)
CGContextFillRect(context, subRect)

you can wrap it in a function, and call it in drawExtras or some where else.
