Using MeterGrapher
The Graph form can be initiated via ‘Graph Old Logs’ in the MeterGrapher’s Options menu when MeterGrapher is offline, or via the Status form when MeterGrapher is Online.

Select the display type (you need to stop logging to do this). Strictly speaking, lines should not be used as we do not know the value between readings.
Sets the scale to include all logged values.
Double the Y and/or X Axis increase the scale. For example Y Axis scale from -2 to 12 will double to -8 to 18.
Size of the dots (2 to 5)
MeterGrapher Graph remembers your previous displays. Use the Back and Fwd buttons to scroll through the displays.
Add available meters via this drop down menu. Once all meters are displayed the menu is disabled. A maximum of 8 meters can be displayed.
Remove meters from the graph. Once all meters are removed the menu is disabled.
If the last points are in the display but the next points would be out of view the graph will scroll to keep the latest points in view.
Click and drag the mouse cursor from top left to bottom right over an area to zoom in. Use the Back and Fwd buttons to scroll through the displays.
Note that when logging, a maximum of 3000 points will be shown in the graph. Without this feature PC performance is adversely affected. If this value is exceeded the earliest points are deleted. Note that this only affects the graph when logging. All data points are written to file, and Graph Old Logs will show all points. (Tested up to 132,000 points).
Legend for meters currently being displayed. A maximum of 8 meters can be displayed – if you want to add another, delete one first.
Simple print of chart on one page.
