Together they can be used to implement AJAX style applications. The rrdFilter module can be used to filter datasources (DSs) and apply user-customized filter objects such as mathematical operations. This module also has methods to Filter RRAs for time shifts (for timezone implementation) and/or Averaging (for creating new, averaged RRAs with different step sizes). See the rrdJFlotFilter.html (DS Filters) example and the rrdJFlotFilterRRA (RRA Filters) example.

The rrdFlot module can be used to plot a single RRD file.
- See also the rrdJFlot.html example and the same graph with all rrdflot_defaults available options shown.
The rrdFlotMatrix module can be used to plot a list of RRD files.
- See also the rrdMatrixFlot.html example.
