<p:barChart id="category" value="#{machineReport.barChart}"

 public void setLineChartData(ArrayList machineBoList) throws IOException{
        private CartesianChartModel barChart=new CartesianChartModel();
        switch(reportType){
        case 1:

I'm not sure you can. On my system, the sample barchart wasn't an image, it was a collection of HTML5 elements. If you want an actual jpg image, you may have to employ some other charting tool.

barchart is object of CartesianChartModel of prime faces , My question was ,simply save it as and images like jpeg or png etc. Dear Tim Holloway this not HTML 5 element,
I want save <p:barChart > as an image.

What it is in your source code and what the rendering process produces on the client side are not the same object.

On the client side on my browser, it was not "an" HTML 5 element, it was a collection of HTML5 elements arranged so that they would look like a bar chart to the client plus have special properties such as highlighting when you rolled the mouse over a bar.
