Undo...

Allows you to undo the last 100 operations. If you find that performance suffers when working with large data sets and you can live without this feature, disable it under Options>General. Note: Individual macro commands cannot be undone. To preserve the state of a plot before running a macro, the macro should use the SaveUndo command.

Shortcut:

 

Redo...

Reverses the operation of the last Undo.

Shortcut:

 

Copy Picture

Copies a metafile and a bitmap image to the Clipboard.

Copy Data Values (XY plots only)

Copies the data points of a single curve to the Clipboard.

Copy Dimensions

Allows you to change the size of bitmaps and/or metafile pictures that are copied to the Clipboard by the Copy Picture command.

Paste

Creates a new curve using data from the Clipboard.

Paste Special

Opens a dialog box from which you can choose to establish a link with the source of the data, specify the data type (1D groups, X & Y values, X,Y,Z values for a 3D surface or scatter plot, or X,Y,Z,amplitude values for a 4D surface or scatter plot). You can also use this command to tell DPlot that the clipboard text contains a column of point labels.

Insert Link

Creates a new curve from data in another application, and links the curve to the source of the data.

 
NOTE: All Edit menu commands below are disabled if the currently active document contains linked data (added with Insert Link).
 

Move/Copy Curves (XY plots) or Move/Copy Groups (1D plots)

Allows you to easily move or copy one or more curves/groups from the currently active document to another open document or a new document.

MoveCurves

 

Edit Data

Edit data values for a new or existing curve.

Crop

Delete all data points that lie outside a rectangle you define with the mouse. XY plots and 3D/4D surface plots only. This command is disabled for 3D views of surface plots.

XY plots only

Combine curves

Allows you to append the data values from one curve to another curve. The curve with the source data will be deleted. You may optionally sort the resulting curve in ascending X order.

CombineCurves

Operate on X

Allows you to manipulate the X coordinates using an equation.

EditAddToX

EditMultiplyX

EditOperateX

Operate on Y

Allows you to manipulate the Y coordinates using an equation.

EditAddToY

EditMultiplyY

EditOperateY

Decimate Points

Provides three different methods for reducing data.

Delete Points in Box

Use your mouse cursor to define a box inside which all data points will be deleted.

Equal Intervals

Generates a new curve with a constant spacing on the X axis.

Erase Curve

Wipes out all data associated with one or more curves.

Shortcut:

Click  on the toolbar.

EditErase

 

Filter

Eliminates noise or otherwise alters a time history record.

Remove Random Spikes

Removes individual data points that depart from the trend of a curve by a user-specified criteria.

Remove Trend

Removes any trend from the amplitude by subtracting a straight line through the first and last points (i.e. make the first and last amplitudes equal to zero).

EditRemoveTrend

Replace Data

Replace the data for one curve with the data from another curve, and then delete the source curve. This command is particularly useful when updating an existing saved plot with new data.

EditReplaceData

Normalize

Adjusts the amplitudes of selected curves so that they range from 0-1 or 0-100: Y=scale*(Y-Ymin)/(Ymax-Ymin)

EditNormalize

Smooth

Smooths a data record using a low-pass filter.

Sort

Sorts the data for a selected curve in ascending abscissa (X) order, then in ascending Y order for equal X values. Many DPlot operations are optimized for monotonically increasing values of X, while others may require sorted X values.

EditSort

Swap X,Y

Switches the X and Y values for one or more curves. If the new curve has progressively smaller X values, then the order is automatically reversed so that X increases.

EditSwapXY

Truncate X

Eliminates all data with independent variable outside a user-specified range. If no data remains, the curve and all associated data are erased.

EditTruncate

Clip Y

Eliminates all data points with amplitudes outside a user-specified range. If no data remains, the curve and all associated data are erased. If instead of deleting points you want to simply ignore points outside a range, see the Amplitude Limits command on the Options menu.

ClipY

YYYYMMDDHHMM to Serial

This command translates X values that are dates in the form YYYYMMDDHHMM (for example January 19, 2003 5:25 PM would be 200301191725) to the Excel 1900 date system. This command also automatically turns on Date and Time number format for the X axis and adjusts the time format setting dependent on the granularity of the input values.

Data Processing mode only

Baseline Shift

Performs the same function as Add a constant to Y, but calculates the desired shift and automatically regenerates integrated data in "data processing" mode.

List Editions

Displays a list of all baseline shifts done on a record in "data processing" mode.

Undo Shift

Reverses the previous Baseline Shift performed in "data processing" mode.

3D plots only

Operate on Z

Allows you to manipulate the Z coordinates using an equation.

EditOperateZ

Swap X,Y

Switches the X and Y values for all data points. This option might be useful if, for example, your 3D input files are ordered latitude, longitude, elevation (rather than longitude, latitude, elevation).

Number Triangles

Numbers triangles on a 2D contour plot of randomly-spaced 3D points. This option is useful when deleting individual triangles using the right-click context menu.

Delete Triangles

Allows you to delete one or more triangles from a 2D contour plot of randomly-spaced 3D points. You might find this option useful in either creating holes in the surface of the plot or in overriding DPlot's creation of a convex mesh. For more information see the How To topic "How do I force DPlot to create a triangular mesh of my 3D points that is not convex?", and for an alternative solution see the Define Boundary command on the Options menu.

Delete Thin Triangles

Removes triangles with interior angles less than 5 degrees if the associated triangle vertex is on a free edge. Thin triangles often do a poor job of mapping a surface. Triangle removal is recursive: if triangle B has an interior angle less than 5 degrees which borders triangle A, and triangle A is removed, then triangle B will also be removed.
