How to draw curve between two points in qwt polar?

[ike]

After some investigation of the legacy code we have, we determined that the solution done in the past was simply to interpolate the original set of data (in rectangular coordinates) and create a uniform data set of 700 points. Then we plot those 700 points in polar form and it makes the plot display with the appropriate "smoothed-out" curves.

We implemented this in our new code with QWT and it is an acceptable solution.

Unfortunately, we don't have a more elegant algorithm for this Uwe.

In the meantime I have added a new class QwtPolarFitter, that also simply adds a couple of equidistant points, that makes the lines "rounded". But QwtPolarCurve also allows to add more advanved algorithms by implementing an individual fitter object.

Available from SVN ( which is very close to QwtPolar 0.0.3 )
