Bug 216041 – qtiplot-0.9.4 matrix/3dplot malfunction

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description George Deligeorgis 2008-04-03 14:06:19 UTC]

Importing a large set of data in qtiplot and trying to plot them in 3dplot
results in corrupted plot. The data in the matrix also appear to be corrupted
I have also filed a bug report in qtiplot main page (bug #13543) although it is not clear whether this is due to some lib not working correctly or the main qtiplot application.
I'll try to add the related files.

Reproducible: Always

Steps to Reproduce:
1.Import the ascii data
2.convert spreadsheet to matrix and delete the first 2 columns ( which contain X data)
3.plot 3d wireframe. the curves are partially corrupted on the low x values side.

Actual Results:  
The 3dplot should be symmetric and it is not. A 2d plot on the spreadsheet is helpfull to see the expected shape

Expected Results:  
The 3dplot should be symmetric

Recompiled everything to make sure this is not a broken dependency issue.
Gentoo amd64 on Intel core 2 duo with:

Ascii data causing the malfunction

This is the ascii data that are used to replicate the problem

screenshot of the resulting plots

Plot on the left is the wrong 3dplot.
PLot on the right is the 2dplot of the data in spreadsheet.

Closing this bug. 
It is the ascii data that have a non-uniform x value set.
The software is working as expected.
