Ah, ok let us look at that.

I do believe the data source we have has data in the format POINT
(-118.550003051999994 34.016666412399999).

What is the format for line data?

I'm not sure, I have not used the OGR connection. Assuming it is returning WKT where points are:

POINT(-118.550003051999994 34.016666412399999)

then lines would be:

LINESTRING(-118.550003051999994 34.016666412399999,-118.560003051999994 34.016666412399999,...)

I do not believe that this is possible.
If you want to draw lines you have to create a data source the returns
lines not points.

The problem is that mapserver draws features and each point is a
feature. It does not have a mechanism that can read a data source and
aggregate the point features into a single line feature.

I have seen posts on the PostGIS list for SQL that can do this. You
might ask on the GDAL list if there is a way to do this. Or if you can
use PostGIS, then you can find the SQL in the archives or ask again.

Hello list,

Using an OGR connection to an sqlite data file we can get point and
labels to draw successfully.

However when we try and draw a line using the point data we do not get
anything drawn.

Layer details below.

Thanks
