So my boss asked for some 95th percentile information and I thought "easy enough". I opened up NPM, went to the device, then interface in question. From there is a graph that has 95th% checked, however, there is no line of data on the graph for 95th%. If I click on edit graph, both "show a trend line, and show the 95th percentile line" are checked. Why doesn't this data show, even though this is a built-in graph?
