(Yeah, ok, I have asked before..... B-u-t.....)
I have a screen with multiple charts. Alas at this point all but one are inactive. It is the one which is the problem.
(Oh, when the others are getting data, they are 99.9% black, as per settings.)
So, this chart - like the others - has the setting for the trace set to BLACK.
Usually it is blue - which I now can say is actually the second colour of the settings - and I had the first colour as BLACK.
I don't get why it is/was blue. But of late it has behaved itself and become black.
Alas it has decided to go back to blue.
I haven't edited anything in the flow anywhere near the chart to cause the data flow to change to the second colour.
Today I worked out it was the second colour because after seeing it was back to BLUE, I went in and looked at the settings. BLUE was the second colour, and if I change it to another colour, the trace colour changes.
But it is colour #2. Not #1.
This is annoying to me - though I could "cheat" and just make all the colours BLACK and not care. But I don't think that is the right thing to do.
Can anyone offer suggestions to why it is changing between colour #1 and colour #2 of the settings?
