How to create extrapolation in line graph in jasper?

[cheapwebhoster]

Is it possible to create interpolation or extrapolation graph in jasper report designer? If possible please advise the following

1. How can i do it?
2. Is it possible to make the predicted line (extrapolation/interpolation) to be in different format of line graph. For example the true data is presented by the solid blackline and the extrapolated line is dotted line
3. basically its a forecast graph

See example

You can do that using highcharts (HTML5 Charts) api.

By the way thanks for the answer zh3ntil ....i have another questions ... it seem that is possible for a fix data...how about data that is dynamic meaning the value in the database will change over time? Can it be done to create a new extrapolation/forecast line when the real data is getting more/updated?
