My data appears as a single point in the map window

Occurrence

When I open the map window after I have created points from my data table, the points appear in a
single point in the center of the map window.

Solution

This occurs when there is a mis-match between the projection of the point data and the projection of
the table's map. Check the projection of the Map window and table matches that of which the points are created in.

To check the Table's projection go to Table->Maintenance->Table Structure and click the projection
button.  Alternatively right click on the layer in the Enhanced Layer Control and select Show Table Projection.

If this is the correct projection (.. it matches the projection your co-ordinates are recorded in), go to
Table->Create Points make sure to choose the same Projection and check the 'Overwrite
Existing Points
' option.

If the projection of the Table is wrong, go to Table->Maintenance->Table Structure and untick
Table is Mappable. This will delete and clear the incorrect map.  Now tick the box again and select
the correct Projection. Now you can go to Table->Create Points, making sure to choose the same
Projection
as the table.
