Graph Data
- This section should be written by AJ.
+ Select this button and you are prompted to select a flight
+ record file, either a .telem file recording telemetry data or a
+ .eeprom file containing flight data saved from the TeleMetrum
+ flash memory.
+
+
+ Once a flight record is selected, the acceleration (blue),
+ velocity (green) and altitude (red) of the flight are plotted and
+ displayed, measured in metric units.
+
+
+ The graph can be zoomed into a particular area by clicking and
+ dragging down and to the right. Once zoomed, the graph can be
+ reset by clicking and dragging up and to the left. Holding down
+ control and clicking and dragging allows the graph to be panned.
+ The right mouse button causes a popup menu to be displayed, giving
+ you the option save or print the plot.
+
+
+ Note that telemetry files will generally produce poor graphs
+ due to the lower sampling rate and missed telemetry packets,
+ and will also often have significant amounts of data received
+ while the rocket was waiting on the pad. Use saved flight data
+ for graphing where possible.
