TUFLOW Viewer Matplotlib v3.5.1 Bug: Difference between revisions

Matplotlib is the Python plotting library used by TUFLOW Viewer. We have found a bug in version v3.5.1 of this library that can mix up the plotting datasets being displayed in the plot window if the user makes an update to the dataset labelling in a certain way. More information on the bug is given below. The Matplotlib library version installed in QGIS is controlled by the QGIS distribution and not something we have control over. AsThe ofbug writingappears thisto page the latest, and only version, this seems tobe affectintroduced isin QGIS 3.24. It may persist into future releases of QGIS if the bug is not fixed in the Matplotlib library, or if it is fixed then it must also be updated in the QGIS distribution.

Users can potentially workaround this bug by ensuring that the order of the labels in the selection box within the customise options dialog stays the same. Or alternatively, the error only occurs if the user re-enters the customise dialog after changing the labels (as demonstrated by the example above) so the user can update the plot labels without scrambling the dataset if they only edit the labels once.<Br>
