chart_img.show()
chart_img.save("101566.png")The project only includes one set of skin00_rip skins. If you want to use other skins, you can download them from Bestdori, use Tools for Cutting Unity Sprites to cut them, rename them, place them in the resources folder, and change the value of SKIN to the folder name.
