[Qgis-user] Problem installing Profile plugin

[Pedro Venâncio]

Hi Etienne,

>> Does this happen just with a 2-point polyline (when initially created)? How about if you first create (and save) a 3-point polyline before using the plugin?

It's the same, the plugin can not create the profile for the last segment of a polyline (if the polyline has only one segment, then it creates nothing).

Should I fill the tickets in http://hub.qgis.org/projects/profiletool/issues ?

Thanks!


Regards,
Pedro

I think this is due to major differences between 1.0 and 1.1 - I'll
try to look into this and probably just disable the matplotlib version
unless it's 1.0.
Unless someone has a fix for this...

probably a problem in plugin unloading.  Please file a bug report.

If I add another point, the Plugin only creates the profile for the first segment. If I create a fourth point, it just creates a profile for the first and second segments. And so on.

Does this happen just with a 2-point polyline (when initially
created)? How about if you first create (and save) a 3-point polyline
before using the plugin?

Please file another bug report for this issue.
