Composite graphing in reconnoiter is pretty handy. To create a composite graph you will use the same RPN functions as you would to manipulate normal graphs.
The datapoints consist of the numeric datapoints that you’ve added to your graph, indexed off of zero.
For example, if you have four data points for system CPU, and you want to make a composite you can put the following in the function field:
Then hide all of the datapoints apart from the composite one.
