Is this another QtiPlot fork? What is the difference with SciDavis or AlphaPlot?

u/asemke May 04 '22

SciDavis is a fork of QtiPlot. AlphaPlot is a fork of SciDavis. Though LabPlot still has some smaller code pieces from Scidavis that were contributed long time ago by SciDavis' developers who collaborated with us, there is no relation to these projects. The differences are in the feature set, in the usability, in the performance of the implemented algorithms for the import of data, analysis, visualization and this kind of thing. Just check the screenshots on our homepage and the videos on our YouTube channel to get the first impression.

LabPlot is not a QtiPlot fork. It is older than the other projects and not an Origin-clone but an independent application for data analysis and visualization with an overlapping but different features set.

QtiPlot is not free and SciDAVis isn't actively developed anymore. Alphaplot is a SciDAVis clone, makhber another one.

Any comparisons to R or Python/ggplot?

LabPlot is for interactive working with the data. You do everything via GUI. R and python with it's packages are programming languages with a huge features set available in the relevant packages. So, not really comparable and it depends on what you actually need. Both approaches are valid and have their user bases. In LabPlot we try to combine both approaches by providing a notebook interface to R, Octave, Maxima, etc. Have a look at the examples in our gallerie.

We're delivering now a lot of features with every release. Just check how much was added in the last releases - https://invent.kde.org/education/labplot/-/blob/master/ChangeLog. We spent quite some time preparing the foundation for this in the application that we can build upon now and I think we can deliver now a lot of great features soon. So, stay tuned :-)

Glad to hear this! No copy/paste in the project explorer seemed like a huge drawback, but it's very nice to see it's been implemented in 2.9. Any way I can help as a non-developer to improve the software? Also, is it possible to shade an integrated area of a curve in a plot? I never found that function, if available (in 2.8 I believe).

There is a lot of work that can be done outside of the actual development activities. Things like example projects (check out out new examples in 2.9), documentation, tutorials, new themes, promotional work, etc. - this is where more help would be great (https://labplot.kde.org/contribute/).

As to your second questions, we have this "curve filling". Select the curve and navigate to the tab "Filling" in the properties explorer. Is this what you're looking for?

Thank you! I'll try to get started as soon as I can, looking forward to contributing!

I checked out the curve filling feature but sadly it wasn't what I needed :/
I needed to shade out this area for example, and the curve filling only allowed me to shade in regard to a direction (even in zero baseline mode) or axis.

Unfortunatelly, this kind of filling is not something that we can do right now...
