Add the time series plots to the panels. now that we have set up our user interface and built the call back, we can define a time series chart. the chart uses the lat long selected by the user and builds a time series for ndvi or evi at that point. it takes the average ndvi or evi at that point, extracts it, and then adds it to the time series. Use ui.chart.image.series to display an image time series for a given region; each image band is presented as a unique series. it is useful for comparing the time series of individual image bands. here, a modis image collection with bands representing ndvi and evi vegetation indices are plotted. I've been trying to generate time series indexes charts and print it on the panel, but the savi index chart ends up looking just the same as the ndvi chart, besides, the range is wrong (0 1.5).
