@bakanarchie,

In jQuery plugin, you can get reference to the chart object using $(“#chartContainer”).CanvasJSChart(). And you can update any of the options – like $("#chartContainer").CanvasJSChart().options.data[0].type = "column".

However if you like to update chart-options and call chart.render(), as a first step you need to get chart reference as $("#chartContainer").CanvasJSChart(). Once you have reference to the chart, you can update the chart-options and call chart.render(). Please refer second example in jQuery integration page for a live example.
