Charts: Custom xAxisRenderer

[npmrtsv]

I'm trying to set my custom xAxisRenderer like this:

  class CustomXAxisRenderer: XAxisRenderer{
  }

  chart.xAxisRenderer = CustomXAxisRenderer(viewPortHandler: chart.viewPortHandler, xAxis: chart.xAxis, transformer: Transformer(viewPortHandler: chart.viewPortHandler))

But after that I can't see any xAxis labels or grid lines, because of incorrect valueToPixelMatrix. What is correct way to set custom renderer?

Ok, I solved it.

  chart.xAxisRenderer = CustomXAxisRenderer(viewPortHandler: chart.viewPortHandler, xAxis: chart.xAxis, transformer: transformer: chart.getTransformer(forAxis: .left))

VERY HELPFUL! Thanks
