# MeanRasterPixelValuesOverTime

The MeanRasterPixelValuesOverTime is a plot operator that computes a time series plot of mean raster values. For each time step in the raster time series, it computes one mean value. The output is a plot in Vega-Lite specification.

For instance, you want to plot the mean temperature of a monthly raster time series. Then, you can use this operator to generate a time series plot.

## Parameters

ParameterTypeDescriptionExample Value
timePositionstring (start, center or end)Where should the x-axis (time) tick be positioned? At either time start, time end or in the center."start"
area(Optional) booleanWhether to fill the area under the curve. Defaults to true.false

## Inputs

The operator consumes exactly one raster operator.

ParameterType
rasterSingleRasterSource
