Grouped bars in Combined chart

[pilot34]

Hello! Thank you for the great library.

In Charts 3.0 you added method open func groupBars(fromX: Double, groupSpace: Double, barSpace: Double) to group columns from different dataSets in BarChartData

But what if I have such BarChartData inside CombinedChartData combined with LineChartData? I need to recount coordinates for line too, but I'm afraid there is no such method.

Example

I have 2 x-values here. Line have both values and 2 groups of bars have values. But line is displayed wrong.

Should be smth like that:

What do you think about a support of grouped columns with lines?

I don't understand what's your issue. You should follow how ChartsDemo or the API to implement combined chart. Check Combined chart demo.
