NT8 chart scaling [F] mode

Hello

Hello,

You can access this property using the following syntax:

ChartControl.ChartPanels[idx].Scales[idx].Properties.YAxisRangeType

YAxisRangeType can be Fixed or Automatic
where idx is equal to the Panel and Scale index you are trying to access.

I look forward to being of further assistance.

I am trying to set autoscale to automatic using this property:

ChartControl.ChartPanels[0].Scales[0].Properties.YAxisRangeType = YAxisRangeType.Automatic;

But I get an error (Object reference not set to an instance of an object.).

I also cannot "read" the value of YAxisRangeType (Same error). I am doing this inside the OnBarUpdate of an Indicator. I simply want to set the scale to automatic at the end of the day, at 031500 time. Is there a better way? Thanks.

Hello

Thank you for the post.

It looks like something has changed since this post was created, I tested this syntax and also get an error. I was able to use the following successfully to gather the scale and set its properties:

Ensure you have the following using statements at the top of the file:

using System.Linq;
using NinjaTrader.Gui.Chart;

if (ChartControl != null)
{
	ChartPanel cp = ChartControl.ChartPanels[0];
	if (cp != null)
	{
		ChartScale scale = cp.Scales.First(s => s.ScaleJustification == ScaleJustification.Right);
		if (scale != null) scale.Properties.YAxisRangeType = YAxisRangeType.Fixed;
	}
}

This includes error checking for null objects. You can control the panel using ChartPanels[0] and then pick the scale needed by its ScaleJustification. ScaleJustification == ScaleJustification.Right

I look forward to being of further assistance.
