Gnuplot errors or warnings found - invalid palette option

Dear FLUKA/Flair experts,

I installed FLUKA and Flair on window10 using WSL (ubuntu 18.04). I tried to load my previous flair project and it works well, but there is an error for a 2-D color fluence plot as the following figure shows


The color on the plot seems abnormal as shown in the following

Do you have any experience to correct this? Thank you very much for your time and help.

Best,
Xi

Dear Xi,

I the latest Flair version, there was an overhaul of the color palettes.

It seems that you selected the color bar manually in your plot, and it is not working any more. You may try to select it again, or simply recreate the plot.

Cheers,
David

Hi @horvathd David,

Thank you very much. I wonder where to select the color bar,

I tried to create a new plot without any setting changes, it looks normal,

The old plot “electron” was from the old flair project in version 2.3, maybe not compatible with the new version? is that possible? Thanks.

Best,
Xi

Dear Xi,

you can access the color bar option by clicking the cb: button in the Axes field. See:

Then you can select the wanted palette in the dropdown menu.

This may fix the problem with your old Flair project, but a lot of things changed since Flair 2.3.

Cheers,
David

Dear David,

That works, my old flair project was using “FLUKA”, this new version is “fluka”.
Thank you very much for your solution and the details.

Best regards,
Xi
