Any of your Daily and 15 Min. Interval graphs support the ability for you to print them through the web client. We recommend the approach written below rather than printing the entire webpage.
In the toolbar, on the left-hand side of each graph, the Print icon is listed fourth from the top. Select that icon, and you will immediately be prompted with a print preview for the corresponding graph. You may need to select the Print icon again in the top left-hand corner of the print preview window. Only the data you are currently displaying or overlaying on the graph will be included in the print.
