Plot by hand on scatter plot

[yannJFreeChart]

Hello,

I'am a french student, so I'm sorry for my English.

I have a serie of point that I plot on a scatter JFreechart.
I would like to draw points by hand when I click on the graph and get back their coordinates.

Is it possible and how to do that ?

Thank you.
Have a good day.

Hi!

Drawing on charts is not directly supported by JFreeChart. However, Searching the forum got me to this post which might help you.
If this is not what you need, try searching for the ChartMouseListener interface.

Thank you for your reply.

In fact, I don't have to draw point when I click on the graph but I want to get back the coordinate of the mouse.

I try with

Code: Select all

frame1.addMouseListener(this);

With this I can have the coordinates all over the frame when I click with the mouse exept when the mouse is on the graph.

So, I try with :

Code: Select all

chart1.addChartMouseListener(this);

but this method is undefinied for JFreeChart.

Do you know how to do ?

Something like this:

Code: Select all

ChartPanel chartPanel = new ChartPanel(chart);
chartPanel.addChartMouseListener(this);
