(How) can I change millisPerPixel on the fly while resizing?

When resizing the canvas, I'd like to millisPerPixel stay relative to the canva's width. Can I do that?

        var elem = document.getElementById("chart");
        var chart = new SmoothieChart({millisPerPixel: 1000 * 100 / elem.width, maxDataSetLength:2, grid: { millisPerLine: 1000, verticalSections: 1 }});

This way I always has 100 seconds of data worth on the chart with data points arriving one per second. The desire is to keep it this way even when the canvas is resized. Possible?

Actually, I'm just being dumb here, I can change char.options on a live chart and it will do what I want. Sorry for the noise.
