Since you aren’t allowed to use HTML in
drawTextyou can’t use<sup>andsub. Instead have to do it yourself.In other words, when you want superscript you will need to change the font to be smaller and either draw the text at a higher y-position or else set
textBaseline = "top". For subscript you will have to do similar.Otherwise you can use unicode. For instance it is valid to write:
ctx.fillText('x₂', 50, 50);,ctx.fillText('normalText0123₀₁₂₃₄₅₆₇₈₉', 50, 50);, etc.
