The date of every image observation is included along the Image collection with bands representing NDVI and EVI vegetation indicesĪre plotted. Use ui. to display an image time series for a given region Įach image band is presented as a unique series.

Region reduction is performed on ecoregions defined byįeatures in a FeatureCollection designed for demonstration purposes The following examples rely on an ImageCollection that is a time series of The reduction of image pixels in a given region, grouped by day-of-year, for a Region, grouped by day-of-year, for a selected image band. Y-axis values are the reduction of image pixels in a given Series are defined by years present in the Image day-of-year is plotted along the x-axis according to theĪre the reduction of image pixels in a given region, grouped by day-of-year.

Y-axis valuesĪre the reduction of images, by date, for a single image band. Y-axis valuesĪre the reduction of images, by date, for a single region. Image date is plotted along the x-axis according to the Examples in the following sections useĮe.an() as the argument for both of these parameters. Reduction ( regionReducer) and another for intra-annual coincident day-of-year Ui.* functions take two reducers: one for region I.e., what elements define x values, y values, and series.

Use the following plot diagrams as a visual guide to understand how eachįunction arranges spatiotemporal image collection reduction results in a chart Use the following function descriptions and examples to determine the bestįunction for your purpose. The chart, i.e., what defines x- and y-axis values and what defines the series. The choice of function dictates the arrangement of data in The ui.Chart.image module contains a set of functions for rendering chartsįrom the results of spatiotemporal reduction of images within an
