Y Axis Fix

[DaveS]

Hi Everyone
Is it possible, in the indicator panels, (not panel 1 of course), to set the Y axis to have a constant range e.g. -100 to +100. Sometimes automatic Y axis scaling masks what is realy going on. If an indicator sometimes swings between -100 and +100, but at other times only between -1 and +1 (say), automatic scale changes can lead to a similar appearance when the meaning is quite different.
If its possible to set a fixed range could you tell me how to do it please?

Thanks
Dave

Hello,

To fix the range add two plot lines and fix their values like this:

Add(new Plot(Color.Black, PlotStyle.Line, "Zero Line"));
Add(new Plot(Color.Black, PlotStyle.Line, "100 Line"));

Values[1].Set(0);
Values[2].Set(100);

The above fixes the indicator panel range 0 to 100.

Thanks Ben, just what I wanted.
Its a pity that I had to ask though, I'll bet there is a VERY large amount of useful stuff like this that, like Values.Set, is not in the user documentation.

Values[] is in the documentation. It is just another way to access your plots without calling its particular name. The .Set is just like how you would set any other plot value.

I see how its meant to work now, however, I spoke too soon, it doesn't work for me.
I now have -

protected override void Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "PlotSlope"));
Add(new Line(Color.FromKnownColor(KnownColor.DarkOliveGree n), 0, "Zero"));
Add(new Plot(Color.Black, PlotStyle.Line, "Plus20"));
Add(new Plot(Color.Black, PlotStyle.Line, "Minus20"));
Values[1].Set(20);
Values[2].Set(-20);

CalculateOnBarClose = false;
Overlay = false;
PriceTypeSupported = false;
POsc = new DataSeries(this);
}


The code compiles OK, but does not draw any of the plots. The Y scale is fixed at 0 to 1.

You cannot set it in the Initialize() method. You need to set it in the OnBarUpdate(). It is just like any other plot. No different.

Doh!

Thanks
