Lets you plot display filter field values over time.
As shown above, this window contains a plot drawing area along with a customizable list of plots. Plots are saved in your current profile. Each plot shows the value of the specified field (see Y Field below) at each point in time. Hovering over the plot shows the packet number of the selected plot at any given time. Clicking on the plot takes you to the corresponding packet in the packet list. You can drag the plots around with a left click and zoom on a specific area with a right click.
Individual plots can be configured using the following options:
