Briefly |
Use control-click or drag to zoom in, control-shift-click or drag to zoom out. |
One way to zoom in is to adjust the axes.
But another is to use the cursor. If your mouse pointer is over something that can zoom, hold down the key. The pointer will change to a magnifying glass. Click to zoom in.
If you're looking at a slider, for example, you can zoom in by -clicking on the axis numbers.
If you're looking at a scatter plot, you can also drag a rectangle (the marquee) with the magnifying glass. When you let up the button, the region you had enclosed expands to fill the entire graph.
Holding down the and keys together reverses the sense of the magnifying glass; that is, you zoom out instead of in.
