X and Y-Axes

The Y-axis (vertical) displays the scale of the measured temperature. Lower values are at the bottom and higher values at the top.

The Y-axis includes temperature labels on the left side of the graph. These four temperatures divide the vertical axis into four equal parts and are automatically scaled to fit the current Y-axis limits. These units can be displayed in Celsius or Fahrenheit using the Units command in the Preferences sub-menu on the Watch worksheet.

The X-axis (horizontal) displays values data points collected. The X-axis can be converted from data points to time or distance using the Units command in the Profile menu.

To see the X-value of any location on the Data Graph, the X/Y Readout in the Status bar continuously displays both X and Y-values at the location of the mouse pointer. Details of this feature are described in section Status Bar.
