GetYByValue

[KhaosTrader]

Hi,
I guess this is not supported in Ninja 8

ChartControl.GetYByValue(this, price);


So I looked at using

protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
{
  // gets the pixel coordinate of the price value passed to the method
  int     yByValue = chartScale.GetYByValue(Close[0]);
 
  Print("yByValue: " + yByValue); // 207
}

the problem is that I have many plots, and when I use this override, even if I have nothing in the brackets, it causes my plots to stop painting.

Is there an efficient way to get GetYByValue?

Thanks in advance

Hello KhaosTrader,

Add

base.OnRender(chartControl, chartScale);

to the first line of OnRender().

This will allow the other plots to render as well.

The ChartScale is provided by OnRender. After it is available you could save this to a handle (variable) and use this how you would like. Generally it is most efficient to use a condition to trigger your code only when necessary (instead of on each pass of OnRender().

Hi There,

When I override Render, my usercontrolcollection buttons stop showing up. Even with
base.OnRender(chartControl, chartScale);
What can I do?
