Graph Copy

Generate/6002.gif The Copy Graph to Clipboard option in PeakLab Graphs offers a variety of formats for copying the current graph or its numeric contents to the clipboard.


Clipboard Object

The following clipboard graph copy options are available:

Windows Bitmap to Clipboard

Windows Metafile to Clipboard

Windows Enhanced Metafile to Clipboard

All Numeric Info as Spreadsheet Block to Clipboard


Use Color

Bounding Frame

To copy the graph as a Page-White image, simply uncheck the Use Color item. When the Bounding Frame box is checked, there will be a thin-box at the boundaries of the image.

Graph Size

You must specify the Width and Height of the image. If Size with Window is checked, these fields will automatically change as you size the window.

All Numeric Info

The Numeric Info is the only option that does not export the graph image. This option copies all of the numeric information used to create the graph to the clipboard in a spreadsheet format. It is easily pasted into Excel and many other Windows applications. Note that for large graphs with many component peaks, this may be a very large data block with thousands of rows and dozens of columns.

With this option built into the PeakLab graphing engine, you should never be at a loss for retrieving the numeric information in any graph. Everything used to create the graph is placed in this copied data.


A Windows bitmap is a raster image consisting of pixel-type information. A bitmap will accurately retain the positioning of all elements within the graph and its titles. The main drawback to using a bitmap image is the significant loss of resolution that occurs when the program importing the graph stretches, shrinks, or otherwise scales the image. This is especially true for an aspect ratio that differs significantly from the original image. You will almost always be successful pasting a clipboard bitmap into an application.


Windows metafiles consist of a series of Windows graphics vector instructions which are intended to reproduce the original image. Windows Metafiles offer superior resolution and scaling, although the program importing the image may have difficulties in properly rendering text elements such as superscripts, subscripts, and symbols in their proper positions. Metafiles are highly sensitive to the individual applications importing them. If you are unsuccessful in pasting a clipboard metafile image into your software, you should try importing a disk-based metafile using the Graph's Save option. That Windows Metafile saved to file will use an Aldus Placeable Format option which produces a disk-based Windows Metafile that is "placeable". This is the Windows Metafile format preferred and sometimes required by high-end desktop publishing and drawing software. The default file extension for Metafiles is [.WMF]. You may also wish to try the newer Enhanced Metafile format.
