CorePlot stipes filling

Question

I'm trying to set a stripes filling for a graph created with CorePlot. I've found an example on internet:

CPColor *firstStripesColor = [CPColor colorWithComponentRed:1.0 green:1.0 blue:1.0 alpha:0.0];
                CPColor *secondStripesColor = [CPColor colorWithComponentRed:1.0 green:1.0 blue:1.0 alpha:0.6];
                CPFill *areaStripesFill = [CPFill fillWithFirstColor:firstStripesColor secondColor:secondStripesColor stripeWidth:2];
                scatterPlot.areaFill = areaStripesFill;

I think this code is using an old version of the CorePlot library (I'm using 1.0). I just changed CPColor with CPTColor and CPFill with CPTFill but no method called fillWithFirstColor:secondColor: is present. I would like to create a filling like the one in the iPhone Stocks app.

Any idea?

thanks a lot

Here's the code that makes the background fill for the stocks theme:

CPTGradient *stocksBackgroundGradient = [[[CPTGradient alloc] init] autorelease];

stocksBackgroundGradient = [stocksBackgroundGradient addColorStop:[CPTColor colorWithComponentRed:0.21569 green:0.28627 blue:0.44706 alpha:1.0] atPosition:0.0];
stocksBackgroundGradient = [stocksBackgroundGradient addColorStop:[CPTColor colorWithComponentRed:0.09412 green:0.17255 blue:0.36078 alpha:1.0] atPosition:0.5];
stocksBackgroundGradient = [stocksBackgroundGradient addColorStop:[CPTColor colorWithComponentRed:0.05882 green:0.13333 blue:0.33333 alpha:1.0] atPosition:0.5];
stocksBackgroundGradient = [stocksBackgroundGradient addColorStop:[CPTColor colorWithComponentRed:0.05882 green:0.13333 blue:0.33333 alpha:1.0] atPosition:1.0];
stocksBackgroundGradient.angle = 270.0;
plotAreaFrame.fill = [CPTFill fillWithGradient:stocksBackgroundGradient];
