dataIndex in toggledSelectionForPoint:


#1

Hi everyone,

i’m using the _sChart: toggledSelectionForPoint: inSeries:   _to get informed whenever a point in a line chart is pressed. But i’m having problems to get the dataIndex of the point being pressed. I need to know the Index to find the corresponding data object.

I tried subclassing SChartDataPoint to add the index directly there but the SChartDataPoint received by the delegate method is different from the point created in sChart: dataPointAtIndex: forSeriesAtIndex:

Any ideas?

Regards,

Stefan

Hi Stefan,

The index property on the datapoint should be the index of the closest datapoint to the tap (based on the chart’s interpolation) - are you managing to get an index back from the datapoint? If so, what kind of values are you seeing?

Best regards,

Rob

Hi Rob,

the index property is exactly what I was looking for. Thanks!
