Zoom in and out of a graph
Use the zoom tools to magnify a graph or bring back a standard view.
Zoom In makes the window smaller around the centre, so you see more detail. Zoom Out does the opposite. A standard zoom resets the view to -10 to 10 in both directions.
After zooming, open the window settings to see the new edges.

Tips
- If a graph disappears after a zoom, go back to a standard or decimal zoom and start again.
- ZoomFit (when your model has it) chooses the y-range for you so the whole curve fits.
