auto scale for indicator

[onnb1]

hi all,

Say I have an indicator, that plots several lines all within the range of 2000-2200. When I add it to a chart, it opens in a new panel. The right access starts at 0 and goes all the way up to 2500. So initially, the lines are all bunched together. I then can manually adjust the scale so that the right side displays 1900-2500 and then I can see the separate lines. Hope this makes sense.

Is there a setting that I can set that does this automatically? that will scale the panel based on the values on the visual area of chart?

There is an indicator in the file sharing that will help.
I hacked it up for my battery level indicator for 0-100 scale.

You can set "AutoScale" for that indicator to true. If you superimpose it to a second inidcator, then set it to "Overlay".

Hello onnb1,

Thanks for your post.

You can set the alignment of an indicator with ScaleJustification.

For example:
ScaleJustification = ScaleJustification.Left;

For added indicators to a strategy you can also set these.
For example:
Add(SMA(19));
SMA(19).ScaleJustification = ScaleJustification.Left;

thanks for all the replies. I understand that the scale justification would come into play if I was using overlay as Harry mentions.

I am sorry to have waster your time but I think I found the "problem". One of my plots is set as a Bar. It happens that all the values for that plot are N/A. I am guessing that regardless of the N/A, just because it is a bar, NT will start the scale at zero. When I remove that specific plot, the panel basically displays automatically as I would expect it to.

If that is true, my 2 cents to NT is that if a plot has N/A's, it should not be taken into account when scaling.

Hi onnb1,

I think it may be possible to accomplish this with code.

For example:

in Initialize():
Add(new Plot(Color.Blue, "myplot"));
AutoScale = false;

in OnBarUpdate():
Value.Set(myIntHere)
if (myIntHere > 0)
{
AutoScale = true;
}

I tried setting autoscale to true in the initialize section. It did not help. Is there any reason you have it set that way in OnBarUpdate?

Hello Onn,

After making AutoScale set to false in the Initialize section, you will need to remove the indicator from the chart, and the re-add it.

• Right-click the chart -> select Indicators....
• Select the indicator from the list of active indicators on the bottom left -> click the Remove button
• Click Apply
• Select the indicator from the master list on the top left -> click the Add button
• Click OK

The proposed changes will keep the autoscale false by default, then when the value of the line is greater than 0 it will change this to true.

Is this what you were looking for?
