Figure 32. Selecting the Measurement Units for the Data Streaming Graph

To select which measurements are displayed in the graph, check or uncheck the temperature and relative
humidity boxes shown next to the graph units. Selecting or not selecting the data types only affects the
graph and not the data logged to a file. If a data type is not enabled in the Configuration page it will not
appear on the Data Streaming page.
