List Peak Values

Displays a dialog box listing minimum and maximum amplitudes and the point at which they occur, along with mean, standard deviation, and standard error for each curve.

Shortcut:

       Click on the toolbar.

List Peaks within a Range

Identical to List Peak Values, but first allows you to specify a range in X using the cursor. Click on the plot at one end of the desired range, then drag the cursor to the other end of the range and release to display the minimum and maximum amplitudes within the selected range.

Shortcut:

       Click on the toolbar.

 

Interpolate...

Reports an interpolated amplitude for each curve at a user-specified abscissa.

Scan X, Y

Displays data values for a single curve as you scroll through the data.

Find Baseline

Finds the average amplitude between a user-specified range of points. Useful for performing baseline shifts.

Number of Points

Reports the number of data points in each curve.

Find Intersections

Finds the intersection(s) of one curve with another curve, optionally adding data points at the intersections and labelling those points. Both curves must have monotonically increasing X values. If necessary you can use the Sort command on the Edit menu prior to Find Intersections to sort curves in increasing X order.

Distance from

Reports the distance and slope between two X,Y points (not necessarily points on a curve). You can use your mouse to click and drag from one point to another, or of course enter the coordinates in the respective text boxes. Please note: the distance reported is simply the square root of the sum of the squares of the horizontal and vertical offsets, in whatever units are used for X and Y. The reported distance may therefore be meaningless. Exception: If both X and Y use either Degrees, Minutes or Degrees, Minutes, Seconds number format then DPlot assumes those values are longitudes and latitudes on the Earth, and reports the distance between points in both miles and kilometers.

Check "Snap cursor to nearest data point" to find the distance between two data points, rather than translated mouse position.

Shortcut:

       Click on the toolbar.
