(II) Graph Display Controls
By default, the graph will automatically scale the axes of the graph to display all the data within it. The view
can be controlled manually using the following mouse controls:
•
Left/Middle click and drag – pan the axes.
•
Right click and drag – scale the axes.
•
Scroll wheel – scale the axes.
A specific axis can be controlled by using these controls on the axis labels. The axes can be reset by clicking
the ‘A’ button in the bottom-left of the graph, as shown in
Figure 9.7
.
(III) Selecting and Removing Curves
When there are multiple curves on the graph, one of them is considered the active curve. This curve will be
displayed in blue, whilst the other curves will be grey. By default, the last curve to be measured is the active
curve. You can change which curve is the active curve by clicking on any curve using the left mouse button.
To remove an individual curve from the graph, click on it using the left mouse button to make it the active
curve, then press the Delete key.
