PlotJuggler: custom plots, filters and transformations
Things you will learn
- Ready to use data filters for your every day needs.
- Write your own function using Lua.
Analyze data with Filters
- Right click with the mouse and open "Apply filter to data..."
- You can apply a filter to any of the timeseries in the plot, for instance try the "Derivative" or "Scale/Offset"
Custom timeseries 1/X
- You can create a custom timeseries using Lua.
- Drag and Drop an "input timeseries" and write the body of the function that will transform the input into a new series.
- Check Learn Lua in 15 minutes, but you can stop after 5 minutes :)
Custom timeseries 2/X
- You can use multiple inputs, but keep in mind that all the data points MUST share the same time axis.
- Use the "Function Library" to save/load reusable functions. Double-click on the name of a function to load it.
Custom timeseries 3/X
- When your function returns a single value (most common case) the new data point will use the same time as the input (X) but the returned value (Y).
- If your return two values, the first is the new time and the second is the new value.
- To skip a point, return no values with "{}"
Custom timeseries 4/X
- Currently, PlotJuggler uses Lua 5.4
- You can use any of the Mathematical functions.
