Conversion question

[blar58]

Hello,

I am converting an indicator from 7 to 8 and cannot find the right conversion code for this :
this.ChartControl.YAxisRangeTypeRight = YAxisRangeType.Fixed;

Help would be welcomed


Thanks

Hello blar58, and thank you for your question.

In NinjaTrader 8, the YAxisRangeType property is now a property you set panel-by-panel. Since a direct equivalent to your code is not available, and there are new concepts to understand in NinjaTrader 8, I am going to provide a more generic code sample first, then later, one that resolves your query.

This code sample will force every panel to automatic scaling. You can try it out. Just load it into an indicator's OnBarUpdate, and then with this indicator enabled, try to adjust a scale. It will snap back to automatic after a moment each time.

[FONT=Courier New]foreach(ChartPanel panel in ChartControl.ChartPanels)
{
  Print("--------------------------------------------------------------------------------");
  foreach(ChartScale scale in panel.Scales)
  {[/FONT][FONT=Courier New][FONT=Courier New]
    Print("now setting '" + scale + "' to automatic");
    [/FONT]scale.Properties.YAxisRangeType = YAxisRangeType.Automatic;
    Print("This scale is" + (scale.IsVisible ? "" : "n't") + " visible");
  }
}[/FONT]

ChartPanels[0] is your topmost panel, and every panel beneath it increases this index by 1.

As far as Scales, if you run the above sample, you may get output like this :

--------------------------------------------------------------------------------
now setting 'Scale: Right #[B=1;I=0;S=0;D=0] min=2176.94 max=2178.06' to automatic
This scale is visible
now setting 'Scale: Left #[B=0;I=0;S=0;D=0] min=1.79769313486232E+308 max=-1.79769313486232E+308' to automatic
This scale isn't visible
now setting 'Scale: Overlay #[B=0;I=0;S=0;D=0] min=1.79769313486232E+308 max=-1.79769313486232E+308' to automatic
This scale isn't visible
--------------------------------------------------------------------------------

This means that Scales[0] is your Right scale, Scales[1] is your Left scale, and Scales[2] is your Overlay scale. This also means that you can use your Scales[n].IsVisible property to determine which scales are active.

With all that understood, then, the equivalent to your code is

[FONT=Courier New]foreach(ChartPanel panel in ChartControl.ChartPanels)
{
  panel.Scales[0].Properties.YAxisRangeType = YAxisRangeType.Fixed;
}[/FONT]

Here is a top level documentation link, from which you can drill down into ChartPanels and Scales.

Great.

Thank you very much Jessica. I will play with this.
