When you call a method such as fillRect() after translate(), the value is added to the x- and y-coordinate values. 

context.translate(x, y);

Parameter Values

You can specify one or both parameters.

Parameter Description
x The value to add to horizontal (x) coordinates
y The value to add to vertical (y) coordinates
