Can anyone provide step by step instructions for using jfreechart in IntelliJ project

I haven't used IntelliJ before, but I downloaded it and immediately created a new project called JFreeChartExample File -> New Project

. Then I clicked File -> Project Structure...

and selected entry Libraries

, then clicked the icon +

to add both jcommon-1.0.23.jar

and jfreechart-1.0.19.jar

(which I had on my local filesystem after unzipping the JFreeChart distribution). Then in the directory src/

I created a new Java file BarChartDemo.java

(see below). Now my project looks like this:

BarChartDemo1.java looks like this:
