Hello Bjoern,
thanks for the information.

Hi Regina,
Hello,
I have download the chart developer snapshot milestone 8. I tested a
spiral graph in xy scatter and find that it is still broken, when
using smoothing (which is issue 13699). Are you working on that issue,
so that it will be fixed in the new chart module?
No, we haven't addressed this issue yet. We have this on the list for
after integrating the new chart into the master. It requires a different
algorithm for spline calculation. This should be no rocket-science, but
it will still take some time to implement and test this.
At least one additional year :(
To fix this it would suffice to change the implementation of
SplineCalculater::CalculateCubicSpline() (just noted the wrong
orthography of calculator) in chart2/source/view/charttypes/Spline.cx.
So, if there are any volunteers who want to provide a new algorithm for
that, you are wellcome. The current algorithm sorts the x-values
and calculates splines with an algorithm that requires sorted x-values.
Unfortunately I have not enough time to try a solution myself.
BTW, Milestone 9, the "Beta" is coming soon, so stay tuned. In this
release the range-chooser for selecting ranges from Calc with the mouse
finally works and includes of course many other improvements.
That's good news. I hope the version is so good, that I can start to
write some guides and test all its steps.
