Display diagonal line when only one point is selected

[#1]

I have a graph like this:

This is my dimension tab:

This is my expression tab:

The third dimension is there to create the diagonal line (see the linear reference at the bottom left in my expression tab). I got the idea from here (Reference Line)!

When I select only one point in the graph the line disappears (see below). But I want it to remain there. Other solutions to display a diagonal line are welcome too. Thanks for the help!!

Hello,

Try Sum({1} IST) instead of Sum(IST).

Nice idea but unfortunately the not selected points stay in the graph (see below):

[#4 · Accepted solution]

My workaround is to create a second scatter chart which will only show up when only one entity is selected. Then make the background of that scatter chart transparent and add a diagonal line object. You need also to fix the axis both to 100%.

There is also the possibility to make those points at the bottom transparent and then it will look like that it works. The only two drawbacks are the performance because the selection stays the same and the legend still shows the not selected points but in grey color.
