This tool shows in separate panels the three components of the magnetic field and the total magnitude of the field.
The time range shown by the plot is defined by the time range chosen by the user before the plot was created. Using the manual time entry boxes at the top of the window, you can switch to a time range more narrow than the original one. But you cannot widen the time range using these entry boxes. To get a wider time range, you must launch the tool again, first selecting the wider time range that you desire.
Note that you may have more than one of these magnetic field plots (or any other plot) up at the same time, although if you are looking at a wide time range (more than a day or two), you may quickly run into memory problems on your computer.
