I am trying to find a way to plot 2 sets of data against each other while flying (e.g. one data set is y axis and the other is the x axis). Currently, I can only plot them separately with time as the X axis. I am viewing this data by selecting it from the “Tuning” menu.
This data is obtained by some sensors on an arduino, then it is sent over uart to the FC and logged using a LUA script.
For good plotting, log analysis ,graphing, fast and responsive data scrolling, scaling and much more related to tuning, nothing beats Apmplanner2 , be sure to check it out.
Plot in the Tuning menu and in general all log analysis software has time on it’s X axis.
You have to export the data and use some third party plotting solution if you want x/y scatter.
If your script put the data into the onboard log, you can extract them from there for plotting.
