A thin yellow line indicating where the each data point in the vector layer is projected on the profile line. Default: On
.
A marker on the profile line indicating the location of the data in the plot. Default: Off
.
Plots can be saved as raster or vector file with various format (jpg, png, pdf, svg).
You can export data and profile line, and import profile line
Data used in the plot can be exported as text data with csv format.

Pixel size (px/map unit) can be set manually. You can also import alignment files which you used in WiscSIMS session to set pixel size.
Profile lines are also exportable as shape file. You can reproduce the profile line and plots.
Heavy processing, though.

- as points
Select checkbox if you want to normalize the Profile Line 2 to Profile Line 1.
The length of profile line 2 is normalized by the Profile Line 1
This option needs profile lines which have same number of segments.
