color scale in the ranking tab can collapse to all grey

[jrouquie]

Low importance.

- open a graph with an attribute "weight" on edges, of type "float".
- click tab ranking, edge, choose "weight".
- click in the middle of the color scale (that goes from white to black). A white triangle (a slider) appears.
- move the leftmost triangle to the right until it disapears
Now the color scale goes from grey to black, I see no way to restore it from white to black.

Those steps can be repeated, mirrored (right to left) to make black disappear. One then gets a uniformly grey colorscale, not really useful ;-)

I think it's normal behavior, slider are clickable and color can always been changed.

Having an all grey slider is normal behavior. The problem I was talking about is that the slider in then stuck to all grey. It cannot be restored to a full scale from white to black.

[Mathieu Bastian (mathieu.bastian)]

Hum so I can't reproduce this problem. When you say it cannot be restored to a full scale from white to black, what avoids this? At least two sliders should always remain and therefore one can be white and the other black.

>two sliders should always remain

Yes

>one can be white and the other black.

No.

I have three sliders: white, grey, black. Then I move the white slider to the right until it disappears (strange idea, I admit, but I did it incidentally). I'm left with two sliders, one grey and one black. I cannot have any white in the scale anymore.

[Mathieu Bastian (mathieu.bastian)]

Ok, but why you can't click on the slider and change the color of the slider?

[jrouquie (jrouquie)]

OK, sorry. I didn't know one can double-click a slider to change its color.
