This example performes import and visualization of TUDelft disdrometer data (http://www.disdrometrics.com/). TUDelft disdrometer data delivers rain in mm and dropsize distribution (-, number of drops per class).
Within the Smart Urban Water project, part of the European project "Climate KIC", rainfall and dropsize distribution data from the TUDelft disdrometer had been imported and visualized in Delft-FEWS. Import format is WaterML 2.0.
The used procedure can be useful for import of other sources of rain data including dropsize distribution or more in general for other data with information of internal classes' distribution.
Rain data (mm) and number of drops per class (-) can be imported each as independent timeserie with the import waterml time series parser.

Dropsize distribution (in % per class) can then visualized per timestep as 100% stacked plot, together with rain using the stackPlot="true" option in the DisplayGroups file.
