chartValueSelected Delegate Method Not Called

[socaljoker]

When tapping on a bar using the BarChartView, the chartValueNothingSelected delegate method gets called instead of the chartValueSelected delegate method because the highlight is null in the highlightValue method. I've tried everything to get it to not be null but cannot figure it out.

check

        if callDelegate && delegate != nil
        {
            if h == nil
            {
                delegate!.chartValueNothingSelected?(self)
            }
            else
            {
                // notify the listener
                delegate!.chartValueSelected?(self, entry: entry!, highlight: h!)
            }
        }

You can override it to get what you want.

I did check that. h is always null no matter what. I've set a highlighter on the chart.

well.. you could add breakpoints and trace back to see how it generates highlight object. Please refer ChartsDemo as well.
