Here's the instantaneous radius vector and orbital speed of the selected satellite for 1 orbit centered at the TLE epoch.
There are seven graphs that cover about 30 days (1 graph every 5 days).

In orbitDecayed. For these satellites, the first graph may be unreliable.
Abbreviations meaning
TLE: the epoch of the TLE used (along with the SGP4/SDP4 propagator) to obtain the satellite state.
Rave, Rmin, Rmax: average, minimum and maximum radius vector in kilometers. Rave is equivalent to the semi-major axis. The values in parentheses are the shown values minus 6371 (just to show an approximate altitude).
Vave, Vmin, Vmax: average, minimum and maximum orbital speed in m/s. Vave is calculated as the length of 1 orbit divided by the orbital period.
T: orbital period in minutes calculated as the time taken by the satellite to make a full revolution with respect to the mean equinox of date (this is the "true" orbital period and it is different from the period obtained from the TLE mean motion field).
The graphs show 1.6 orbits, but Rave and Vave are calculated for exactly 1 orbit.
