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

Parameter	Type	Description	Example Value
`timePosition`	string (`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) `boolean`	Whether to fill the area under the curve. Defaults to `true`.	`false`

Inputs

The operator consumes exactly one raster operator.

Parameter	Type
`raster`	`SingleRasterSource`
