Graphing Data
The PanaView network tree has already been described, and the display pane shows only a graph in the default style
with no data points. The bottom right pane enables you to set up the graph. To begin graphing your data, proceed as
follows:
1. Expand the network tree as far as necessary and double click on the process parameter to be graphed. The grid for
the selected graph appears in the display pane, with Time as the x-axis and the parameter Value as the y-axis. In
addition, a legend appears above the graph, which indicates the name, data point shape and line color for that
parameter.
2. If desired, a second parameter may be added to the graph by repeating Step 1. In this case, the parameter "Value" is
shown as a right y-axis (Y2).
Note: Although only two parameters may be graphed for any one meter channel, the same two parameters may also
be graphed for any other active meter channels.
3. To begin plotting data for the selected parameter(s), enter a time Interval for data sampling in the text box provided
(the default value is 5 seconds).
