html5 canvas redraw on resize

Answer 1

I decided to use a scale variable to resize my scales. I resize the canvas canvas.width *= 2; and then I redraw my scales.

var scaleStep;

and use add it into the code: ctx.lineTo(12*24*cScale+12, canvas.height-24); where the scaling needs to be done. The scaleStep is 2 when maximizing the canvas and 1 when returning to the original size.
