Exciton weights

[sdwang]

Dear all,
I used yambopy to plot the exciton weights on the bands, and the weights seems very small as attached.
The script related to the exciton weifghts as:
...
## [3.B] Interpolate the values
if Bands_Plot_Interpolate:
fig = plt.figure(figsize=(4,6))
ax = fig.add_axes( [ 0.15, 0.15, 0.80, 0.80 ])
# In case of problems with the interpolation, try to increase lpratio
exc_on_bands = yexc.interpolate(yel,path,states,lpratio=20,f=None,size=1.0,verbose=True)
exc_on_bands.plot_ax(ax,color_bands='grey',c_weights='red',alpha_weights=1.0)
I increased 'size' but it does not work. If I reduced lpratio, the weights are bigger, but the bands are crossed heavily.
How to solve the problem?
Thanks!
