axis agenda using color

[Haifeif]

Problem

I'm always frustrated when I have to use multiple axis-agendas for the y-axises, because it becomes quite tricky to read or combine the curves with the corresponding axis.

If I have 3 lines (CO2 - red, Temp - blue, Humidity - green) and three agendas for these data - 2 on the left side, 1 on the right side, I need some time to find out what curve is related to which agenda.

Possible Solution

A checkbox, that allow me to set the agenda color to the corresponding curve color. Checked: agenda color = curve color Unchecked: agenda color = properties (like now)

Alternative

Make another properties inputbox to select the color for each axis agenda

Additional context

Like that:

To me, it would help a lot!
