Finally, here's how you can save a chart in high-resolution format specifying the DPI. This is useful when you want your charts to appear in printable material such as PDFs or books.

    BitmapEncoder.savePNG(chart, "./Sample_Chart.png");
    BitmapEncoder.savePNGWithDPI(chart, "./Sample_Chart_300_DPI.png", 300);

The difference is resolution is very clear in the following images.
