The Elevation statistical function show parameter values against the elevation of the location on one particular time. The time for which the values are shown can be altered with a slider bar.
An example of the elevation plot is given here:

Ensemble Percentile Exceedence
The ensemblePercentileExceedence function in the TimeSeriesDisplay allows selection of multiple timesteps to be shown in the exceedence diagram. The function can be used in combination with multiple locations as well as multiple selected forecast. The time series must be part of an ensemble. For a selected time step all ensemble member values of that time step will be placed in an array and will be sorted from high to low values and plotted. In the plot the Y-axis repesents the value of a member and the X-axis repesents the precentage of values that exceed the esemble member.
An example of the ensemblePercentileExceedence plot is given here:
The above plot is based on a selection of 51 ensemble members that are represented in the following plot. (Only two lines shown as many members have the same values).
Configuration example:
| Code Block |
|---|
<statisticalFunction function="ensemblePercentileExceedence"/> |
Frequency distribution
The frequency distribution function divides the distance between the min and max value of the timeseries by the number of samples to create a classification. It then evaluate each value in the timeseries and assigns it to a class. The result is a frequency distribution diagram listing the number of occurences per class. Number of classes (samples) can be selected in dropdown box.

Ensemble Percentile Exceedence
Plots for the selected time stamp(s) each member of an ensemble along the horzontal axis, sorted by value. The result is exceedence diagrams for an ensemble forecast at a selected timestamp(s) within the timeseries.
The function allows multiple locations and/or multiple time stamps and/or multiple forecasts in one diagram. If multiple forecats include the same selected timestamp, the legend only can distinguish between these forecasts if a taskdescription is used during job submission.
