Chapter II-12 — Graphs

II-293

You can use the custom size setting and the related Left, Top, Width and Height parameters to print a graph

of any size at any position on the page.

Printing Poster-Sized Graphs

Using the Custom Size setting in the Print dialog, you can specify a size for a graph that will not fit on a

single sheet of paper. When you do this, Igor uses multiple sheets of paper to print the graph. This makes

very large, poster-sized graphs. Another approach is to specify a custom size that does fit on a single sheet

and use the Reduce/Enlarge setting in the Page Setup dialog to enlarge the graph by, for example, 200%.

To make the multiple sheets into one big poster, you need to trim the edges of the sheets and tape them

together. Igor prints tiny alignment marks on the edges so you can line the pages up. You should trim the

unneeded borders so that the alignment marks are flush against the edge of the trimmed sheet. Then align

the sheets so that the alignment marks butt up against each other. All of the alignment marks should still

be visible. Then tape the sheets together.

If you need to reprint some of the sheets but not all you can use the Pages settings in the Print dialog. For

example, if you need to reprint just sheet two of a four sheet poster, enter “2” in the From parameter box

and “2” in the To parameter box. Now Igor will reprint only sheet number two.

Other Printing Methods

You can also print graphs by placing them in page layouts. See Chapter II-16, Page Layouts for details.

You can print graphs directly from macros using the PrintGraphs (see page V-514) operation.

Save Graph Copy

You can save the active graph as an Igor packed experiment file by choosing File→Save Graph Copy. The main

uses for saving as a packed experiment are to save an archival copy of data or to prepare to merge data from

multiple experiments (see Merging Experiments on page II-32). The resulting experiment file preserves the data

folder hierarchy of the waves displayed in the graph starting from the “top” data folder, which is the data folder

that encloses all waves displayed in the graph. The top data folder becomes the root data folder of the resulting

experiment file. Only the graph, its waves, dashed line settings, and any pictures used in the graph are saved in

the packed experiment file, not procedures, variables, strings or any other objects in the experiment.

Save Graph Copy does not work well with graphs containing controls. First, the controls may depend on

waves, variables or FIFOs (for chart controls) that Save Graph Copy will not save. Second, controls typically

rely on procedures which are not saved by Save Graph Copy.

Save Graph Copy does not know about dependencies. If a graph contains a wave, wave0, that is dependent

on another wave, wave1 which is not in the graph, Save Graph Copy will save wave0 but not wave1. When

the saved experiment is open, there will be a broken dependency.

The SaveGraphCopy operation on page V-553 provides options that are not available using the Save Graph

Copy menu command.

Exporting Graphs

You can export a graph to another application through the Clipboard or by creating a file. To export via the

Clipboard, use the Export Graphics item in the Edit menu. To export via a file, use the Save Graphics item

of the File menu.

The process of exporting graphics from a graph is very similar to exporting graphics from a layout. Because

of this, we have put the details in Chapter III-5, Exporting Graphics (Macintosh), and Chapter III-6, Export-

ing Graphics (Windows). These chapters describe the various export methods you can use and how to

choose a method that will give you the best results.
