You can resize the chart using the resize function that is provided by KoolChart. Set the width and height of the <DIV> element where the chart is created before the resize function is called.
function changeChart (w,h) {
var ch = document.getElementById("chartHolder");
ch.style.width = width+"px";
ch.style.height = height+"px";
document.getElementById("chart1").resize();
}
