These graphs present a graphical representation for the collected data for the last 7 days where you can configure your own graph to compare values together.
Up to nine different data values can be selected or removed using the below drop-down selectors. Each data value has a further drop-down selector to change the colour for that particular data plot.
Mouse over the chart to see the values at any given time. The graphs are sampled each minute. Preset time periods may be viewed using the zoom buttons to top right of the chart and or you can drag the navigator as necessary below the chart.
You can hide or unhide data sets from the chart by clicking the entry on the chart legend.
This data is drawn from a real-time database, and if there are system interruptions there may be gaps in the plotted data. Select-a-period Multi Graphs shows the trends without these gaps but at a lower sampling frequency.
