Initially, the latest LI image is shown. Use the buttons to select other images.

Click on image to get a graph of the values of LI, PW, and CAPE. Note that each click makes a new graph -- the previous one is still there until you remove it (by double-clicking in the upper left corner). Use the Remove markers to remove the markers put on the images for each graph. Use the Close all graphs to close all the graphs and remove the markers.

Presently the closest data to the cursor point will be used; however, if no data are available within about 30km for a given time period, a thin line (or no line) will be used on the graphs.
