Occasionally it is frustrating when we cannot get ICT to do exactly what we want, so it is useful to know some of the constraints of this tool.
Plotting and deleting coordinate points
- Once a coordinate point has been created, it cannot be moved by dragging. To amend its position, you must change the value of its coordinates in the table and then click Update points.
- To delete a coordinate point, point to it and, when the cursor changes from an arrow to a hand, select the point. The point will change colour from yellow to orange. Click on the dustbin icon to delete the point.
- To delete all of the points on the coordinate grid, select Clear all points.
