Drag and drop channels in VIEW always selecting Time as X channel

[Simon_Aldworth]

A highly annoying feature seems to have appeared automatically in DIAdem 2020 VIEW panel and I cannot find a way of switching it off.

It used to be the case that if I wanted to plot a Y channel against an X channel then I would select the X channel in the portal list and then move the cursor so that the arrow turned from white to black and a + sign appeared next to the arrow and then select the Y channel. DIAdem would know that I wanted the second channel plotted against the first.

Now, it doesn't matter whether I move the cursor or not, the two selected channels are plotted against the time channel.

Perhaps it has something to do with the symbols next to the channel names:

The files are imported Excel files using a DataPlugin but a quick check of the script doesn't reveal anything weird there. I also can't find any reference in the portal channel properties that might tell me why it's happening.

How do I revert back to the original method of plotting Y against X channels in VIEW?

Thanks.

Hi Simon_Aldworth,

With DIAdem 2020 we have the new optional feature that a Y channel “knows” his associated X channel. This is like a waveform channel, with the difference that XY channels do not need an equidistant X channel. The X relation is a property of the Y channel.

You have two options for your case.

1. a) You drag and drop the Y channel, open the layout dialog box, and add with drag & drop the X channel.
2. b) You go to ANAYSIS -> Channel functions and open the converter function “Numeric channels <-> XY channels” and remove the X relation

Hi Walter,

Thank you so much for solving that - it was driving me mad.

I have since determined that the problem was created when I setup the DataPlugin to read some Excel files. I didn't spot the innocent looking tick box that asks if you want to set the first channel as the X channel.

Regards.
