Dear Developers,
I am trying to plot the first bright excitons on the band structure. But the excitons are barely visible on the bands. Is there any method where I can increase the colour of the excitons in the plot (I have tried varying alpha_weights and other parameters), or are there any reasons for them to be so light? The second bright exciton is much more difficult to find in the plot. I have attached the plot obtained for the first bright excitonic state. Any suggestions would be greatly appreciated. Regards,

Dear Ponnappa,

When you call the plotting function, such as
You should be able to control the color of the excitonic weights with "c_weights" and their size with "size": do you confirm that by changing the value of these arguments nothing happens?

(Here "exc_on_bands" is the object returned by the interpolating or band structure functions as in the tutorial script at tutorial/databases_yambopy/exc_kspace_plot.py.)

Best,
Fulvio

Dear Palful,
Thank you for the response, which helped in sorting the issue.
