View Menu > Graph View > Set as Start, End Markers > Using the Start and End Markers
The start and end markers are provided as a convenient way of defining an area of interest of the graph. The information presented in statistics view mode normally pertains to the sample record as a whole, but if the start sample marker is not placed at the first sample, or the end sample marker is not placed at the last sample, the same statistics are also presented for the samples defined between the start and end samples.
The start sample is marked on the graph with the 
flag symbol. The end sample is marked on the graph with the 
flag symbol. You can set any sample to be the start sample by positioning the graph sample cursor at that sample, and using the View/Set as Start Sample, function or by pressing F7. You can set any sample to be the end sample by positioning the graph sample cursor at that sample, and using the View/Set as End Sample, function or by pressing F8.

The start and end samples can also be used to quickly determine the daily average temperatures of a sample record. |

A quick way of defining a region on the graph with the mouse is:
•Click on the graph where you want the start sample to be. •With the Shift key held down click on the graph where you would like the end sample to be. |
