Reset to default 33

The second argument is the Y coordinate for the baseline of the text (the default textBaseline is "alphabetic") , so the text is being drawn above the visible canvas element when you use 0.

jsFiddle.

You could use a different number or alternatively, change the textBaseline property to something suitable, such as "top".

ctx.textBaseline = "top";

jsFiddle.
