Data Logging and the Trend Chart Display
l
When data logging to memory, the trend chart maps each reading to a dot in a pixel column, draws a
line between multiple dots in each column, and draws a line from the last reading in a column to the
first reading in the next column.
l
When data logging to a file, if the instrument determines the readings will fit in memory, the trend
chart behaves as it does when data logging to memory. If there are too many readings to save in
memory, the trend chart behaves in a manner similar to that of the continuous measurement mode.
That is, the number of readings shown per pixel column depends on the reading rate and the selected
Time Window.
