a question about the visualization of the curves of measurements.

On my Dashboard I have to add a widget to visualize the values with the
"Field Details" which is more flexible to use.

here is an image for the explanation

In the example, there is no way to do it by clicking on the element
V_LIGHT_LEVEL element of the "LuX panel"?
