hi, a can not install qtiplot in my KDE neon User Edition 5.19. I tried using apt but: Package qtiplot is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source.
So, please, how can I install qtiplot in my system?
Thanks

I am a user, and I found this work is great! I want to visualize the 3D data with the surface plot. Anyway, the raw data was stored as a typical 3-column table as following:

x(1) y(1) z(1,1)
x(1) y(2) z(1,2)
x(1) y(3) z(1,3)
x(2) y(1) z(2,1)
x(2) y(2) z(2,2)
x(2) y(3) z(2,3)

I know there exists an item as "Convert to Matrix" under the menu "Table". I tried to convert the 3rd column (z) to a matrix - if it works, obviously i will get the 3D graphic option for further plot. Unfortunately, it failed to give a 3x2 matrix but keeps the same form as the table. I am wondering whether there is some method to realize the conversion, or some way to visualize this 3-column data easily?

Regards,
Tianmin

Hi,

The issue is solved in the last release of QtiPlot, 0.9.8.3.

Please try it, the conversion should work now.

I hope this helps and best regards,

Hello,

As indicated on the downloads web page of QtiPlot it was required to install Python 2.5.4 separately.

Now I've just added python25.dll to the Windows installers, so just redownloading and reinstalling QtiPlot should fix the issue.

I hope this helps and best regards,
Ion Vasilief
