No there isn't a delegate method that would do that for the sparkline.  The sparkline is designed to be pretty stripped down.  

Yes darrell you are absolutely right. Actually i have read this properties in api. But my question is i want to set x-axis and y-axis in sparkline seires.

Because i refereed api for sparkline, however i didn't found any method for add axes in sparkline series.

Is there any  delegate method in sparkline series like IGChartView having

- (NSString *)chartView:(IGChartView *)chartView labelForAxis:(IGAxis *)axis withItem:(NSObject *)item  

for setting x and y axis label ?

Thanks.

If you want to set a different brush for the negative and positive values you would need to set the .brush and .negativeBrush properties.

Hello Darrell,

The demo is working perfectly.

But my question is can i set x-axis and y-axis in sparkline series as we have in column series in IGCategoryDataSourceHelper ?

Because my ultimate goal is, i want to display column series which have two values. i.g. +ve, and -ve with different colour.

Please give me some suggestion.

Thanks..

Thank you so much Darrell
