I should have given an example to better illustrate the problem. The pump system normally operates every hour except when there is an emergency situation at which time it changes both the volume pumped and the pumping interval.
A typical report to be bar graphed might look like this: 3 4 7 18 15 12 9 8 7 NB. high level 1 2 5 13 10 8 7 6 5 NB. low level 0 1 2 3 3.3 3.6 4.6 5.6 6.6 NB. logged time What I would like to see is the operations correctly located on the X time-line that could be calibrated in either minutes or minimally in 1/10 of an hour. There would be 'clumping' of data along the line.
