I am currently preparing 2-D hydro-dynamics modelling software and would like the software to display the results graphically. I have made some attempts to develop this code but could not go beyond scattered diagram, with out a link joining values of equal magnitude as is obtained in contours. The data could be imported from a data base and comprises the coordinates easting and northings and the values of velocity or elevations. Samples of the input data and the results of my code is hereby attached.
Thanks Ayoub Benayache, I will visit the website and explore the possibilities offered therein.
Ayoub Benayache it's correct.
You can make this with jfreeChart .
I use JfreeChart to plot river flow.
You can use too Jzy3d library.
http://www.jzy3d.org/
"Jzy3d is an open source java library that allows to easily draw 3d scientific data: surfaces, scatter plots, bar charts, and lot of other 3d primitives. The API provides support for rich interactive charts, with colorbars, tooltips and overlays. Axis and chart layout can be fully customized and enhanced."
JFreeChart is the best answer... Works very well and its easy to use. Input the the datasources and it will plot any kind of chart you need
I have tried writing the java code using Jzy3d but it is not recognizing the library. Can anyone assist me to debug the java code and possibly let me know were the problem is coming from?
I have below a link to the sample project including the library.

Charles;
It's worked with me.
But I needed to download some lib for Jzy3d.
That lib that I downloaded.

Hi Albert,
I have run the code on netbeans, after adding all the jar files in the zip folder as you have it.
I still get the following error messages below

Please could you send me the java package that worked with you since i have not been able to identify source of error and necessary corrective measures to take.
Regards,
Charles
Gincker.com has a contour template that allows you to create a contour or heatmap chart by simply typing in mathematical formulas, pasting your data, or loading a data file, without the need to write a single line of code:
