Interpolation Calculator
Use the Interpolation Calculator to interpolate a curve fit's X-value based on a Y-value and
subsequently display the
values
on the graph. The interpolation calculator is different from the interpolate function in that the
Interpolation Calculator remains in place while the interpolate
function moves with the mouse pointer.
Using the Interpolation Calculator
- Perform a curve fit or linear fit on
your collected data.
- Select Interpolation Calculator from the Analyze menu. The
following dialog will appear.

- Select from the pull-down menu the Curve Fit you want
the interpolation calculator to use.
- The current live
sensor reading will be entered as the default Y-value. You can use this
value or enter a value using the keyboard.
- Click OK when done.
A helper object with the X and Y-values
appears on the graph. This can be updated by double-clicking on
the helper object to call up the options dialog. If the curve fit
dialog has multiple X-values for a given Y-value, the square brackets
of the Interpolation Calculator can be used to select the region of the
fit used for interpolation.
