Elevation profiles - option to draw / export to relative scale? #49246

Open walking-the-talk opened 2 years ago

walking-the-talk commented 2 years ago

Feature description

The new core functions for Elevation profile are really useful for working with 3D data but I can't find a way of controlling the scale(s) of the plots - is this a feature that has not been documented? If not, it would be really helpful to be able to fix the relative horizontal and vertical scales (e.g. 1:1 or 1:10) or for it to be mathematically obvious on any plot. Currently my plots are pretty but meaningless / arbitrary in terms of gradients. When exporting to pdf it appears to be possible to specify some parameters, but nothing that directly controls vertical or horizontal scale. And ideally I would like to be able to export to directly to SVG format (but maybe that's another feature request!). Many thanks for your work on this.

As an additional comment, it would be perfect if, in addition to setting the scale as commented, to fix the "y" values for both the export and display of the profile could be modified

In order to automate the generation of a series of profiles it would be interesting to include elevation profile within print composer. In this way, as data on which to generate the profile it would be necessary to set the coverage layer and the vertical/horizontal scale, which could be an attribute of the coverage layer itself.

Did you ever find a solution to fix the vertical and horizontal scales?
