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

In addition to what Eric suggests, you can also try setting the fill to a clear color. For example, I've used this in the past to provide a transparent background to graphs:

CPTTheme *theme = [CPTTheme themeNamed:kCPPlainWhiteTheme];
graph = (CPTXYGraph *)[theme newGraph];

graph.fill = [CPTFill fillWithColor:[CPTColor clearColor]];
graph.plotAreaFrame.fill = [CPTFill fillWithColor:[CPTColor clearColor]];
