We want to zoom in on this area, so we drew a box around it, from upper left to lower right.
Here is our area of interest, zoomed in.
When you release the mouse button, the chart will redraw the area you drew a box around at a zoom level that fills the chart window with your data.
ZOOMING OUT
To zoom back out, press and hold the left mouse button anywhere on the chart window and with the mouse button still pressed, move the mouse up and to the left. The size of the box you draw does not matter when zooming out, you will always zoom out the original size of the template or graph.
