plot combo plots

[TingTingShao]

Hi Klest,

The package ran smoothly, except one error when plotting combo plots (paste_combo_image.py -> render_title). I had to change the code in order to run:

def render_title(combo_width, title, image_dpi_res, font_size=36, title_padding=20):
    font_size = round(font_size * (image_dpi_res / 72))
    # font = ImageFont.truetype("arial.ttf", font_size)
    # set default font if arial.ttf not found
    try:
        font = ImageFont.truetype("arial.ttf", font_size)
    except Exception:
        font = ImageFont.load_default()
        print("Could not load 'arial.ttf'. Using default font.")

Best,
TingTing

Thank you for reporting the issue! This happens when the user does not have the arial.tff font installed on their machine. I was wrongly assuming that it was the case.

I pushed a fix with a fallback to the default font. Let me know if it works, and I can proceed by closing the issue!
