Hi, my boss asked me to write a java program that display chart on a panel. The chart can be pie, bar or line depand on the user choice in a combobox. All the chart's data are read from mySQL server database. I just want you to write me a simple program that can display pie, bar and line chart on a panel/canvas depend on my click on a combobox. Please make it easy to input data for the chart so I can modify it for my needed -> input data from a database's query. Thank You.
