Signal Plot

Use the Signal Plot (Figure 1) to plot Vehicle Spy signals in real time. 

Signal Plot uses "Signal Groups", or collections of signals, to plot.  New groups are created by clicking on "+" and groups are removed by clicking "-" .  Signal groups are edited by clicking the "Select Signals" button and using the Expression Builder.  To choose a different signal group, select it from the drop down list to display that group in the plot. 

The Plot Signals button creates another Signal Plot window.  The Logging button opens the Logging view and the logging status is displayed just below the button.

The Signal Plot tool bar gives different features for displaying and saving your data.  Table 1 describes each of the Signal Plot toolbar controls.  The data plot is seen in the bottom section of the window .  The plot axes can be clicked on and dragged to stretch or zoom them.
