Question

I am using Jfreechart to create a chart. I am displaying this on a swing. I want to save this chart and upload it onto my database. Does anyone know how to do this. If it is not possible what other library can i use for achieving this.

Answer 1

Maybe the easiest way is to save the graph as a PNG:

import java.io.ByteArrayOutputStream
import org.jfree.chart.JFreeChart;
import org.jfree.chart.ChartUtilities;

JFreeChart myChart = ...
ByteArrayOutputStream out = new ByteArrayOutputStream();
ChartUtilities.writeChartAsPNG(out, myChart, width, height);

and then store that byte array as a BLOB in your DB.
