I am quite new to using MaMuT. I am exploring creating spots and cell lineage tracing with it. I was not able to change the spot color as it is described in the tutorial. I tried double clicking on "Set color by" and changing the range. But all I get is a white bar below instead of a spectrum of colors as suggested in the tutorial. (I also clicked on the white bar to try activating it, but no luck).
Here is a screenshot:
How can I solve this?
