How to make CandleStickChart and BarChart do the same action

[z404558]

I have a CandleStickChart and a BarChart below it. When I make CandleStickChart zoom in or out or translate, I want BarChart do the same action.
Do you have a solution about this?

• (void)chartScaled:(ChartViewBase * __nonnull)chartView scaleX:(CGFloat)scaleX scaleY:(CGFloat)scaleY
  {

  NSLog(@"1:scaleX:%f_____scaleY:%f",scaleX,scaleY);

  if (chartView.tag == 100) {

  [_dayK_squareView setVisibleXRangeMinimum:5];
  
  
  [_dayK_squareView zoom:scaleX scaleY:scaleY x:0 y:0];
  

  }

  if (chartView.tag == 200) {
  [_day_Candle_chartView setVisibleXRangeMinimum:5];

  [_day_Candle_chartView zoom:scaleX scaleY:scaleY x:0 y:0];
  

  }
  }

You can achieve this by using

public func refresh(newMatrix newMatrix: CGAffineTransform, chart: ChartViewBase, invalidate: Bool) -> CGAffineTransform
public func zoom(scaleX scaleX: CGFloat, scaleY: CGFloat, x: CGFloat, y: CGFloat) -> CGAffineTransform

zoom is used to get the target matrix, and later used in refresh
and other functions in ChartViewPortHandler
