Points on a line in jfreechart

Question

How to get all the points (x,y) lying on the line connecting two data-points in a chart in jfreechart ?.

In a chart, as we point to the end-points of the line, it shows the x & y coordinates. Can't we get the coordinates at any point on the line (via code)?

As you have two points, use the formulae of a linear equation to obtain the slope and intercept of the line. Once you have the equation, you can evaluate it at any point.

Addendum: The org.jfree.data.statistics.Regression class offers some built-in support for regression analysis.

For more than two points, see this [answer](http://stackoverflow.com/a/6659201/230513) on regression. – trashgod Apr 10 '12 at 19:30
yes, that's an option but doesn't jfreechat provide something for this type of requirement? – vkantiya Apr 11 '12 at 04:57
