-The "Parameters" panel provides pull-down menus to specify variations for the metrics displayed in the usage histogram figure. "Metric" allows for the selection of various usage metrics binned from job records. Available metrics are; CPU, CPU-equivalent, RGU, RGU-equivalent, Memory, Billing, gpu and all specific GPU models available on the selected cluster (e.g. for Graham: gpu:a100, gpu:a5000, gpu:p100, gpu:t4, gpu:unknown and gpu:v100). The "Summation" pull-down allows you to switch between the daily "Total" usage and "Running total" cumulative sum of the usage over the query period. "Include Running jobs" reduces the usage calculation to job completion records when set to "no", but includes all running jobs in the usage calculation when set to "yes". The "Display allocation target by default" pull-down menu sets the default behaviour of the figure window to show the "Allocation target" when set to "Yes" and suppresses it by default when set to "No".
+Use the "Metric" pull-down control in the "Parameters" panel to select from the following metrics: CPU, CPU-equivalent, RGU, RGU-equivalent, Memory, Billing, gpu, and all specific GPU models available on the selected cluster.
+The "Summation" pull-down allows you to switch between the daily "Total" and "Running total".  If you select "Total", each bar of the histogram represents the total usage in that one day.  If you select "Running total", each bar represents the sum of that day's usage and all previous days back to the beginning of the time interval.  If the "Allocation Target" is displayed, it is similarly adjusted to show the running total of the target usage.
+If you set "Include Running jobs" to "No", the figure shows only data from records of completed jobs. If you set it to "Yes" it includes data from running jobs too.
