Plot metrics

Plot one or more series over a period of time. Do this to follow a process, compare sites or look at what happened around an alarm.

Where: Metrics
Who: ViewerOperatorManagerAdmin

In the left navigation, open Metrics.
Select Series.
Find the series you want. Keep View by location to browse by site. To find the same kind of value everywhere, for example every turbidity sensor, select View by tag or type the metric name in the search box.
Select the checkbox of each series. A checkbox on a location, device, metric or tag selects everything under it. A chart appears for each new series as you select it.
Close the list by clicking outside it.
Select the period (the button showing the start and end dates), then choose a preset. For a custom period, see the table below.
Choose how to group the charts with the Location, Device and Metric buttons (see below).

The Series list open, grouped by location, with Conductivity and Temperature ticked under Sicon Filter Hall Series are listed by location, then device, then metric. A tick selects a series; the badge on Series counts the ticks.

Result: one chart for each group of series, over the period you chose. The Series button shows how many series are selected.

Set the period

Choice	What you get
Last hour, Last 6 hours	The period up to now. Live updates start: the charts move forward every 10 seconds.
Last day, Last 7 days, Last 30 days, Last 90 days, Last 365 days	The period up to now, without live updates.
A custom range	Select the first and the last day in the calendar, set the times under From and To, then select Apply. Future dates cannot be picked.

To move through time, use Shift back and Shift forward. Each click moves one period length; and move two. To zoom to a stretch that stands out, drag across it on any chart. Zoom in and Zoom out halve or double the period.

Start live updates works for periods up to 6 hours. If you start it on a longer period, the screen switches to the last 6 hours. Shifting, zooming or picking a custom range stops live updates.

Group the charts

The three grouping buttons decide which series share a chart. A series goes on the same chart as another when it matches on every field that is switched on.

Buttons on	Charts you get	Use it to
Location, Device, Metric (the default)	One chart per metric per device. Lines within a chart are tags.	Read each value on its own.
Metric only	One chart per metric, with a line for each device.	Compare the same value across sites, such as turbidity before and after filtration.
Location, Device	One chart per device, with a line for each metric.	See how a device’s values move together.

At least one button stays on. Grouping changes only how the charts are arranged, not which series are selected.

When a chart mixes units, its title shows a badge such as 2 units. Each unit has its own axis. Hover over the chart for exact values instead of comparing line heights.

Compare two periods

The screen shows one period at a time. To compare, for example, this week with last week:

Choose Last 7 days and read the charts.
Select Shift back once. The charts now show the 7 days before.
Select Shift forward to return.

To keep both periods at hand, save a view with a Fixed time range for each.

Read the charts

Hover to see the value of every line at that moment. Where a line has no value at exactly that time, the hover box shows the value between its neighbors.
Scale: switch to Fixed (start at 0) to judge the size of a change, and back to Dynamic to see small changes. See Dynamic or fixed scale.
Min/max bands: for periods longer than 6 hours each point is an average. Select Show min/max bands to see the lowest and highest value behind each point, so short spikes are not lost.
Samples: on a flow-cytometry series, click a point (Click to view sample) to open that sample.
Arrange: drag a chart by its handle () to move it, and drag its bottom-right corner to resize all charts.

The screen remembers your series, period, grouping, scale and chart size in this browser.

If it does not work

What you see	What to do
A series is not in the list	It has no data in the period. Select Show series without data in range, or choose a longer period. The line {n} series hidden (no data in range) tells you how many series are left out.
A chart is empty or has gaps	The instrument sent no values in that stretch. Check the device’s state on Devices.
Start live updates jumped to a shorter period	Live updates work for up to 6 hours.
The bands button is disabled	The period is 6 hours or shorter, so the charts show raw values and there is nothing to band.
A value shows the wrong unit or number of decimals	These are set for the workspace, not on this screen: see Add and edit metrics.
