example of using gradient for fills

[dam13n]

The demo app included doesn't seem to have any example of this, and I've been having trouble getting it working. Any example apps or code of using gradient fills for line/area charts?

Also, it would be nice to have vertical gradients vs. left-to-right!

Please refer to the customization readme or header documentation.

Implement:

- (JBLineChartViewLineStyle)lineChartView:(JBLineChartView *)lineChartView fillColorStyleForLineAtLineIndex:(NSUInteger)lineIndex
{
    return JBLineChartViewColorStyleGradient; 
}

And supply a left to right gradient:

- (CAGradientLayer *)lineChartView:(JBLineChartView *)lineChartView fillGradientForLineAtLineIndex:(NSUInteger)lineIndex
{
    CAGradientLayer *gradient = [CAGradientLayer new];
    gradient.startPoint = CGPointMake(0.0, 0.5);
    gradient.endPoint = CGPointMake(1.0, 0.5);
    gradient.colors = @[(id)[UIColor redColor].CGColor, (id)[UIColor greenColor].CGColor];
    return gradient;
}

Hope this helps.

So fast, thanks! I was missing that / didn't catch it in the readme for customization. : )
