Linear Fit
The Linear Fit command, in the Common Tools menu, performs a linear least-squares fit on a user-defined region of data, and adds the resulting line as a trace on the chart. In order to use this command, you must specify a region on the Active trace.
- Make the trace on which to fit a line the Active Trace. Do this by right-clicking on the trace and choosing Activate Trace.
- Select a region on this trace using the mouse curve-selection tool.
- After you select the region, choose the Linear Fit command on the document menu. The algorithm now begins to fit a line to the selected region. When the fit is complete, a new trace is added to the chart.
- View the equation for the new line in the Quick View window that appears at the bottom of the your monitor.
