Autoscaling algorithm

[STG82]

Hallo Everyone,

I need to figure out the algorithm of the automatic Scaling in DIAdem for Diagramms.

Or at least if I put a Diagram on Autoscale to read min max and Tick-Step.

is this possible?

I need that for my Reports which are very high automatisated and depending on the size of the numbers other objects have to move.

Thanks in advance

Hi STG82,

Would you please describe what you are wanting to accomplish?  If you are unsatisfied with DIAdem's automatic axis scaling, then you can apply your own algorithm-- do you know what approach would accomplish your scaling goals?

Hallo Brad,

I´m fully satisfied with the Automatic Scaling itself.

My Problem is that I use a 2Y-Time Diagram in my Report (for all Channels the Same Report-Template) and that depending of the scaling 2 Objects have to move.

Like if my Left Y-Scale is from -2 to 0 to 2 the Object shall be closer to the diagram than if the Scale would be -1500 to 4500 for example.

So what I would like to do is taking the Auto-Scale algorithm and then read the numbers for TickStep, Min and Max

no matter if I read it out in the Report or in the script.

I hope u know what i mean and that it is possible. I work already on a autoscale algorithm by myself, but the NI algorithm is really nice already.

Thanks in advance and best regards

Hi STG82,

You can reference the Y axes by either name or index-- here is the name method:

Dim Ystart(2), Ystop(2), Ystep(2)

Call PicUpdate
Call GraphObjOpen("2DAxis1")
  Call GraphObjOpen("2DAxis1_YAxis1")
    Ystart(1) = D2AxisYBegin
    Ystop(1)  = D2AxisYEnd
    Ystep(1)  = D2AxisYTick
  Call GraphObjClose("2DAxis1_YAxis1")
  Call GraphObjOpen("2DAxis1_YAxis2")
    Ystart(2) = D2AxisYBegin
    Ystop(2)  = D2AxisYEnd
    Ystep(2)  = D2AxisYTick
  Call GraphObjClose("2DAxis1_YAxis2")
Call GraphObjClose("2DAxis1")
Call PicUpdate

MsgBox Ystart(1) & vbTAB & Ystep(1) & vbTAB & Ystop(1) & vbCRLF & Ystart(2) & vbTAB & Ystep(2) & vbTAB & Ystop(2)

Muchas de muchas Gracias.

Vielen Dank.

Thanks a lot.

That was exactly what I was looking for. In between i wrote an algorithm which is as exact as the DIAdem-Auto-Scale... but with just reading MIN MAX and TICK I´m more satisfied.

I tried a lot to read that numbers, but I didn´t get the right idea.

Thanks a lot
