How to change font size and font style in plot_dispersion?

[BianTieyuan]

Hi developer,

I want to change line color, font size and font style in Phon.plot_dispersion. However I can only change line color via fig, ax = system.Phon.plot_dispersion(color='green') . I noticed that only few can be changed via this way:

help(system.Phon.plot_dispersion)

Help on method plot_dispersion in module mdapy.phonon:

plot_dispersion(units='THz', yticks=None, ylim=None, color=None, merge_kpoints=None) method of mdapy.phonon.Phonon instance
    This function can plot the phonon dispersion.
    
    Args:
        units (str, optional): units of frequency, selected in ['THz', '1/cm']. Defaults to "THz".
        yticks (list[float], optional): y axis ticks, such as [0, 10, 20]. Defaults to None.
        ylim (list[float], optional): y axis limitation, such as [0, 100]. Defaults to None.
        color (str | rgb turple, optional): line color, can be a str, such as 'r', '#729CBD', or a rgb turple, such as [125, 125, 125]. Defaults to None.
        merge_kpoints (list, optional): sometimes you want to merge two equalvalue points, such as [2, 3]. Defaults to None.
    
    Returns:
        tuple: (fig, ax) matplotlib figure and axis class.

But how to change font size and font style?

Hi, @BianTieyuan, currently, you can directly utilize the source code to plot the results and make any desired modifications. Should you encounter any difficulties in modifying the code, I am available to assist you. Alternatively, you can await the upcoming version, which will unveil a comprehensive user interface for customizing the details of Matplotlib. Numerous features have been prepared for integration in the next release, but verifying them necessitates time. However, my current schedule is occupied with other commitments, hence the release of the next version may be delayed.

For font size and font style:

change code

fig, ax = set_figure(figsize=(10, 7.5), bottom=0.08, left=0.16, use_pltset=True, figdpi=150 )

to this:

mp.pltset(**{'font.serif':'Times New Roman', 'font.size':10})
fig, ax = set_figure(figsize=(10, 7.5), bottom=0.08, left=0.16, figdpi=150 )

Thanks for your reply. @mushroomfire I extracted the data in Phon. dictionary and plot figure myself. The next version would be wonderful and I am looking forward your release.
