Save Chart as Image File

Charts can be saved as jpg or png images.

This is the codeblock for saving a chart to an image.
An IOExpetion must be catched in case the storage device is full or write protected.

//saving the chart as jpg and png in the current working directory
try {
chart.saveAsJPEG("testchart.jpg", 640, 480);
chart.saveAsPNG("testchart.png", 640, 480);
} catch (IOException ex) {
Logger.getLogger(JChartLibApp_SaveAsJpg.class.getName()).log(Level.SEVERE, null, ex);
}
