Displaying the Data Quality

Quality
Range
button

Select the Quality Range toolbar button to display the monitor data
quality statistics on the hydrograph.

As the monitor generates flow data, it assigns each flow data point a
quality statistic between 0% and 100%. When the Quality Range
toolbar button is selected, a multi-colored legend displays on the
hydrograph's Y axis, indicating 10 levels of data quality from 0 to
100%. Low quality (0%) is indicated at the bottom of the legend in
red, and high quality (100%) is indicated at the top of the legend in
green. Each data point on the hydrograph is assigned a quality
percent color corresponding to the legend.

Overlaying Hydrograph Data

Overlay
button

Use the Overlay toolbar button when you have requested more data
than can be displayed on the current hydrograph format and you
want to superimpose the additional data over the first data. For
example, select the Overlay toolbar button when you have
requested 14 days of data, but have selected a 7-day hydrograph
report format. Selecting Overlay superimposes the additional 7
days of data over the first 7 days.
