Set the areaBaseValue and areaFill properties. The base value is the lower boundary of the filled area. This is normally set to the location value of the yRange so that the fill starts at the bottom of the plot area, but it doesn't have to be. The fill can be any CPTFill—a solid color (with optional transparency), an image, or a gradient. For example:

plot.areaFill = [CPTFill fillWithColor:[CPTColor redColor]];
plot.areaBaseValue = CPTDecimalFromInteger(0);

You have to draw (fill) the graph as a closed path with a fill color.

Then, if you also want to have the graph drawn with a stroke, you can redraw (stroke) only the path that defines the lines of the graph with a stroke color.
