Hallo,
I have a WebChart as attached below. The tooltips are very helpful but it is very hard to gather a tooptip. Is there any possibility to affect the sensitivity of the tooltips? It seems that there are only a view pixels you have to gather.
Are you referring to how far away you can be from a point to get a tooltip to appear? If so, there is no way to change this. Feel free to submit a feature request for this behavior:http://devcenter.infragistics.com/Protected/RequestFeature.aspx

Yes. Is there realy no way? Can I make the points a bit larger or something else?
with the larger icon size, there is a larger hit test area for the tooltip. I'm still not entirely sure what you mean by 'sensitivity' of the tooltip, but when I create large icons my I can mouse over a larger area to get the tooltip, because the circles are larger.
Hallo Max,
thank you for your efforts. The point now looking a bit funny and the sensitivity is not much better.
I tried other SymbolIconSizes but either it looks funny or there is now effect to the sensitivity.
There is an extra step for composite chart layers. Layers have their own corresponding appearance classes.LineAppearance lineApp = new LineAppearance();lineApp.IconAppearance.Icon = SymbolIcon.Circle;lineApp.IconAppearance.IconSize = SymbolIconSize.Large;
LineChartAppearance lineLayerAppearance = new LineChartAppearance();lineLayerAppearance.LineAppearances.Add(lineApp);
ChartLayerAppearance lineLayer = new ChartLayerAppearance();lineLayer.ChartType = ChartType.LineChart;lineLayer.ChartTypeAppearance = lineLayerAppearance;
Hi,
this solution sound good. But how do I implement it in a composite Chart. I think I have to put it on my Layer. But I can not set by LineAppearance to my ChartLayerAppearance.
Can you provide a code snipped?
Thanks
You can try making the line's midpoint anchors a bit larger. Larger icon size should give you a larger area to get a tooltip:LineAppearance lineApp = new LineAppearance();lineApp.IconAppearance.Icon = SymbolIcon.Circle;lineApp.IconAppearance.IconSize = SymbolIconSize.Large;
ultraChart1.LineChart.LineAppearances.Add(lineApp);
