WARNING: it has been discovered that if the range of points on a plot is small compared to the size of the value (e.g. an interval of 3000 seconds from 70000000 to 70003000), pgplot sometimes overflows the values for the axis. The PLOT appears correct, but the x-axis values are written as “*”. The default of hkauxplot is to offset the times (offsettime=yes), this subtracting the lowest value (or TSTART if found) from all values in the x-array, and as a fail-safe, this task also forces exponential writing of these values if they are larger than 10000. Later versions of this task will address this problem, but it is felt that the current solution works in most cases.
