Each started chart is tabbed at the top of the Management window. Simply click the tab for the
chart you wish to view.
At any time, you can use the controls at the upper right corner of each chart to pause or stop the

Pausing the chart will stop the plotting of data, but data collection will still occur in the
background.
•
Stopping the chart stops both data collection and plotting.
The detail pane of the chart provides a legend indicating color/plot association. Clicking a row
in the legend results in the corresponding plot becoming highlighted.
If you wish to change the color of a plot, click the color under the Color column and then choose
a new color in the menu that appears.

moment.
