[matplotlib-devel] Canvas HTML5 backend

[Michael T. <mic...@gm...>]

Hi,
  I'm trying to work on the canvas javascript backend I found here
[1]. I'm trying to add text but the canvas origin is at the top left,
how can I transform the co-ordinates from the matplotlib to canvas?

    def draw_text(self, gc, x, y, s, prop, angle, ismath=False):
        ctx = self.ctx
        ctx.font = "12px Times New Roman";
        ctx.fillStyle = "Black";
        ctx.fillText("%r" % s, x, y)
