How to make the chart and the other chart with the same translation

I have a CandleStickChart and a BarChart below it. When I make CandleStickChart zoom in or out , I want BarChart translation.
Do you have a solution about this?

• (void)chartTranslated:(ChartViewBase * __nonnull)chartView dX:(CGFloat)dX dY:(CGFloat)dY
  {
  // please code in here
  }

take a look at ChartTransformer and ChartViewPortHandler's methods. There are some playing with the matrix, like

    public func refresh(newMatrix newMatrix: CGAffineTransform, chart: ChartViewBase, invalidate: Bool) -> CGAffineTransform

There are some guys asked about this quesiton already.
