How to display point shapes with delegate protocol

[EY]

My chart can display point shapes by setting them directy like below:

series.style.pointShape = [TKPredefinedShape.alloc initWithType:TKShapeTypeCircle andSize:(CGSize){8, 8}];
TKChartPaletteItem *pointPaletteItem = TKChartPaletteItem.new;
pointPaletteItem.fill = [TKSolidFill solidFillWithColor:UIColor.whiteColor];
pointPaletteItem.stroke = [TKStroke strokeWithColor:UIColor.greenColor];

TKChartPalette *pointPalette = TKChartPalette.new;
[pointPalette addPaletteItem:pointPaletteItem];

series.style.shapePalette = pointPalette;


But how to display point shapes with delegate protocol?

I tried this:
- (TKShape *)chart:(TKChart *)chart shapeForSeries:(TKChartSeries *)series atIndex:(NSUInteger)index

but it seems it is not working.

Hello Erkan,

It looks like an issue in TKChart. I confirm that this method is never called. I logged the issue and it will be addressed in our upcoming release in Q1 2015. Here is a link to our feedback portal where you can track/vote/or comment on that issue. I updated also your Telerik points for reporting it. I hope the specified time frame is feasible for you.

Should you have other questions, do not hesitate to ask.

Hello, 

I don't think it's intentional, but you can cause the delegate method to trigger by defining the pointShape on series.style. Here's my line of hackery that gets the ball rolling:

series.style.pointShape = [[TKPredefinedShape alloc] initWithType:TKShapeTypeCircle andSize:CGSizeZero];

Hi Eytan,

Thank you for pointing that out. I confirm that in this case the shapeForSeries:atIndex: method is being called. However, this method should be called in all cases. The good news is that this issue is already addressed in our development branch and the fix will be available with our upcoming release in February.

Should you have other questions, we will be glad to assist.
