There are various ways to export the plots generated by PGOPHER for
use by other programs,
depending on the required result.
Text File with Numbers
This is produced by File,
Export, Main Plot and choosing .txt or .dat as the file type, or
Edit, Copy Main Plot and
then pasting into another application. The produces a text file, with
curves as a simple list of x,y points, one pair on each line. If
there is more than one curve in the plot (a simulation and overlay for
example) a blank line separates each curve. These files should be
easily readable by spreadsheets or scientific plotting programs. Notes:
- For multiple
curves the x axis points are
not necessarily the same, particularly if both a simulation or an
overlay are involved.
- Plotted points and measuring lines are also included in the
export, and show as a separate "curve" with one or two points.
- You may need to go via a spreadsheet or text file if you have
multiple curves to select the required curves.
Key Tip: Shrink the main
PGOPHER window to 1/4 - 1/8 of full screen before producing the plot.
(This will give larger lettering and symbols in the plot produced,
which is usually required for paper illustrations and PowerPoint
The easiest method is system dependent, though File,
Export, Main Plot can also produce SVG or Xfig plot files on any
system. For all these plot options note two settings in the Plot Menu under Plot Options:
|Selected by default, allowing
size on printout, clipboard and export to reflect on screen
on-screen plots typically have rather small characters, but if the main
window is reduced in size then the characters in the plot produced are
increased in size in the resulting plot.
If the option is not selected the character size remains fixed as the
window size is changed.
||Select (default) to limit
of segments on a plotted curve. It can be helpful to unselect this
option if you intend to edit exported plots. The only drawback is that
the resulting plots can be too complicated for some programs to handle.
Use Edit, Copy Main Plot
and the Edit, Paste
in Microsoft Office or other applications. This will
allow you to select "picture" as the type, which gives the plot
directly. (If you use normal Edit, Paste you will normally see the list
of numbers as described in "Text File with Numbers" above.) If using
Microsoft Office you can edit the resulting picture by right clicking
on it and selecting "edit picture" and then "ungroup" - this seems to
work better in PowerPoint than Word. Other drawing programs will have
It is not currently possible to
export plots via the clipboard; consider the vector graphics formats
below. Alternatively, installation of the cups-pdf package (available
most Linux systems) provides a "fake" printer that produces pdf files.
Simply use File,
and select "Cups-PDF" as the printer.
It is not currently possible to export plots via the clipboard;
consider the vector graphics formats below. Alternatively, a pdf or
postscript file can be produced from File,
Print and clicking on the "PDF" button.
Vector Graphics Files
Export, Main Plot allows the vector graphics formats to be produced:
- A .svg file, which can be read and edited by various
graphics programs, including Firefox for reading and Inkscape or Open Office.org Draw
- xfig format, associated with TEX.
