While the parameter accepts the float value, the legend does not reflect that choice between 1 and 1.5

Now it's awkwardly on top. Isn't it strange how each trace isn't defined on a proper legend that you can toggle on/off?

I created an issue (#4932) regarding the overlap, which already has a pr linked to it now. Shall we merge this and then adjust possibly adjust it and add a legend for each trace after #4941? The pr fixes the --std argument and the missing legend for each trace is an overarching thing for the whole TA menu, so it should be its own issue.
