5.5.2 Data Trend
Vertex M plots gas concentration in the Data Trend window. Multiple points may be chosen to
plot each point on a different colored line on the graph. Data displayed in the graph can be
either Stored data from the data log or Live (a continuous, real-time display, scrolling right to
left).
Data can only be stored if datalogging was selected in the Profile Management Utility screen. A
maximum of one year of data can be stored, however faster datalogging rates may require more
frequent purging. Stored data shows only concentration (not location names).
TIP: Drag a finger across the screen to zoom into the selected area.
Information for each point appears in the table to the left of the graph.
Figure 5-10. Data Trend

Y axis data: points to display (to a maximum of 8), the data to display (live or stored) and the
time span; and
X axis data: one, some or all detection values.
TIP: Touch Help for additional information on using the Properties dialog.
