Graph

The main graph plots the data at 30 minute intervals. Selecting part of the graph will zoom into the data further, with a 'Reset Zoom' button appearing to go back to the default. Hovering over (or clicking on Tablets) any data point will provide the date, time, meter number and value

Expanding the graph  is useful if you are using a smaller screen or many meters, however, the default view will always show all the options as above

 Where does the data come from and how do you get the best out of Meter Analysis?

The activity will display any Meter that has a consumption periodic channels (with data recorded at regular intervals) for gas and electricity.

If the Site is selected (indicated by a green tick)  then 1 line on the graph will display a total of all meters available at the site for the period selected.
