This is an interactive graph of measurements of the Hubble parameter from the literature. Drag the canvas to pan. Double click or use the mouse wheel to zoom in and out. Click the legend to hide/show different datasets, and click any datapoint to get the corresponding reference.

The data used in this plot is taken from the excellent and comprehensive list of Hubble parameter determinations maintained on John Huchra's homepage. After 2010 the datapoints come from my own quick search of the literature, if I've missed anything please feel free to contact me and I'll add it.
