New Section plot No line layer selected issue

[jonasstromb]

Hi,

I´m trying to plot my first section plot using QGIS 3.34.1 and Midvatten 1.7.15.

Everything has been done accordingly to the steps in Midvatten wiki "Create section plot".

Featuring layers obs_points along a obs_lines polyline and a DEM in file in a projected coordinate system ESPG 3006

When plotting, the following error appears: "No line layer was selected. The stratigraphy bars will be lined up from south-north or west-east and no DEMs will be plotted". As shown in the picture below.

I see that the problem has been discussed in an earlier post 2021.

Is this a bug or is it just something I am doing wrong?

Regards Jonas

Hi! You need to select the line layer containing you profile line (layer Polyline?).

Hi, Thank you for answering.

Sorry, but i was using the obs_lines layer. Since the feature in the map was highlighted it should have been selected.

When trying once again now just to make sure i actually did select a line layer, a Python error appears.

I´m able to plot a section without a line layer selected. But with the error only a blank section is plotted. I tried once more on another computer, having the same error:

An error has occurred while executing Python code:

The plugin only supports QGIS 3.28 so far (the latest LTR release). The error you get is caused from a change in QGIS >3.30. I will check if it's simple to adapt it to 3.34.

I installed QGIS 3.28 and now I can do a section plot. Thank you for helping out!
