Problem with function

[Igor]

Hi,
I've got a problem while trying to apply function (one-value-function, like tfCorrelation) on my serie. Right after plotting it looks like this:

But after starting to drag graph with right mouse button right axis looks like this:


Then if I do unzoom movement (left click from bottom-right to up-left) it returns to state on first image.
Thanks in advance

Hello,

I can't see the images you tried to add on your post. Could you please try to correct them?
Also, we'll probably need a simple example project we can run as-is to reproduce the problem here.

Hello, I've edited first post. If you can't reproduce the problem, I'll upload example later.

Hello Igor,

Are you linking the different series to different vertical axes?
If you still find problems with it, please try to arrange a simple example project we can run as-is to reproduce the problem here.

Hello,
Of course I'm linking different series to different vertical axes. They have different scales, so on one axis they will not be observable. Simple example in attachment, try to drag it.

Hi,

Try hiding the right axis grid:

Code: Select all

Chart1.axis.right.gridpen.visible = false;

[Igor]

I've hidden grid, but there are still multiple "0.214" values on the axis and correlation line drops down when starting to drag.

Hi Igor,

What about setting right axis increment, for example:

Code: Select all

Chart1.axis.Right.Increment = 0.01;

[Igor]

Have you tried it on your side? When I set increment, I see no label at all at the right axis when starting dragging, and correlation line still drops down.

Hello,

Try adding this at the end of your onLoadFunc. I can scroll the chart here always getting the "0.214" label on the right, with the latest TeeChart ActiveX version published, v2014.0.0.2.

Code: Select all

Chart1.axis.Right.SetMinMax(lineF.YValues.Value(0)-1, lineF.YValues.Value(0)+1);
Chart1.axis.Right.gridpen.visible = false;
Chart1.Axis.Right.Labels.Clear();
Chart1.Axis.Right.Labels.Add(lineF.YValues.Value(0), lineF.YValues.Value(0).toFixed(3));

Hello,
Thanks for response. Your code works but looks like dirty solution. If I apply more functions to this graph, I'll have to set new axis bounds each time which I didn't mean to do.
I think when right axis is set to automatic, it is not normal behaviour that I see now.

Note I suggested this trick because your right axis was in a quite particular situation: a single series assigned to the axis, with all its YValues being the same. This situation is internally handled showing a unique label in the middle of the axis.

If you add more series to the right axis, you shouldn't need such a trick and you can set it to be automatic again.

Is it normal that I need a trick at all in that situation? Why doesn't it just work?
