If a channel is absent from one of three channel groups, and each channel group has a symbol, Curve expansion reassigns the order of the symbols. How to stop it from reordering the symbols for the channel groups.

Hello,

I have three channel groups and each of them are assigned specific symbols. A triangle, a square and a circle. I have a diagram where a channel is missing from the first channel group ie. the one with the triangle symbol. When i create the plot, the channel group with the square is assigned the triangle symbol and the channel group with a circle is assigned the square. This is not desired as the legend still shows that the triangle belongs to the first channel group , the square to the second and the circle to the third.

Can anyone please help me solve this problem?

P.S : I have attached the screenshots

Thank you

Hi Pars Chandaria,

I'm sorry, I think you're stuck.  If you always have 3 groups, then you can assign 9 curves and dedicate the first 3 to the first group and the second 3 to the second group and the third 3 to the third group, by group name.  Then if the the first group is missing, the second 3 curves will still point to the name of the desired group, even though it's group index is [1] now instead of the [2] it originally was.

The curve expansion explicitly ignores group names and simply follows the symbol list by index, based on how many groups it finds in the Data Portal.  Would it be possible for you to switch to explicit curves and away from curve expansion?
