Show BarChar In JTable Column In Java
I have JTable in that I need to Show Chart but i have tired several Code but not able to achieve waht i wanted to make. here what i have tried so far
http://www.jroller.com/Thierry/entry/swing_barchart_rendering_in_a
and i want to achieve according to this image
but how ever i dont get any Render-er for same. Please Any suggestion will be welcomed.
Solution
Okay, here's an idea...
Instead of using a JTable, you could create a layout manager which would calculate the offsets and allow for elements to overlap "columns"
Prototype example - !! DO NOT USE IN PRODUCTION !!
This is an EXAMPLE only and should be used to LEARN from, do not try using this in production, there is a lot that needs to improved, such as a proper event notification API
This example makes use of the JIDE Common Layer API (the JideScrollPane in particular), you can get a copy from here
