NMIS8 uses the RRDTool time series database tool for data storage and graphing, when . When RRDTool has to represent very small or very large numbers are represented , it will use units instead of showing many decimal places.  The following table summarises those units.


So in the chart below the little m in this case is 100m to 900m milliseconds is in fact 0.1 to 0.9 milliseconds.







If you find this feature undesirable you can adjust the relevant graph definitions to NOT use unit autoscaling.

Code Block
# ... header lines
%hash = (
# ...
   'option' => {
       'standard' => [
# ... lots of graph definition statement lines
        'small' => [
