core plot custom Theme?

Question

I\'m using Core-Plot for a trend chart in an iPhone app and haven\'t found how to customize the background. I can create a theme using the built-in themes, like kCPPlainWhiteThe

Answer 1

I used the .fill and .plot.AreaFrame.fill properties :

plot = [[CPTXYGraph alloc] initWithFrame:CGRectZero];
CPTTheme *theme = [CPTTheme themeNamed:kCPTSlateTheme];
[plot applyTheme:theme];
self.graph.collapsesLayers = NO;
self.graph.hostedGraph = plot;

plot.paddingLeft = 1.0;
plot.paddingTop = 1.0;
plot.paddingRight = 1.0;
plot.paddingBottom = 1.0;
plot.fill = [CPTFill fillWithColor:[CPTColor clearColor]];
plot.plotAreaFrame.fill = [CPTFill fillWithColor:[CPTColor clearColor]];

This works for me.
