To obtain more accurate slopes:
Magnify a portion of the Data Graph using the Magnify tool, and repeat this procedure.
To remove the slope line from the Data Graph, select the Erase Object(s) command from
the Tool menu and follow instructions in the Tool Status box (refer to section 5.8.8
Erase Object(s)).
Slope Applications:
Use the Slope tool to find the average slope between any two points on the graph.
Longer slope lines tend to produce more accurate slope calculations.
The Slope tool can be used to compare actual data with ideal conditions by drawing a
line with a known slope (to represent the ideal condition) beside a portion of a Data Plot.
Slope Limitations:
Slope calculations are based on logged points connected by the slope line. Points occur
only at the exact time intervals used to record data.
The Slope tool cannot measure slopes when dx (change in X) is equal to zero (when
the line is vertical).
The Slope tool can be accessed on the Profile worksheet Toolbar.
