The textAlign property

The textAlign property sets how any text that you draw on the canvas is aligned. It can be left, center or right aligned. The left / start and the right / end values may appear to be very similar or identical.

Examples of setting the textAlign property

These are the possible values for the setting. It should be noted that RGraph only uses three of these values - left center and right

    window.onload = function ()
        var canvas  = document.getElementById("cvs");
        var context = canvas.getContext('2d');

        context.textAlign = 'start';
        // context.textAlign = 'end';
        // context.textAlign = 'left';
        // context.textAlign = 'right';
        // context.textAlign = 'center';

        context.fillText('Some example text', 200, 25);
