Chapter II-12 — Graphs

II-237

You can zoom in on a region of interest, expand or shrink horizontally or vertically and you can pan

through your data with a hand tool. You can offset graph traces by simply dragging them around on the

screen. You can attach cursors to your traces and view data readouts as you glide the cursors through your

data. You can edit your data graphically.

Igor graphs are fast. They are updated almost instantly when you make a change to your data or to the

graph. In fact, Igor graphs can be made to update in a nearly continuous fashion to provide a real-time oscil-

loscope-like display during data acquisition.

You can also control virtually every detail of a graph. When you have the graph just the way you like it, you

can create a template called a “style macro” to make it easy to create more graphs of the same style in the

future. You can also set preferences from a reference graph so that new graphs will automatically be created

with the settings you prefer.

You can print or export graphs directly, or you can combine several graphs in a page layout window prior to

printing or export. You can export graphs and page layouts in a wide variety of formats suitable for editing

in a drawing program or for inclusion in a word processor or page layout program with publication-quality

results. See Chapter III-5, Exporting Graphics (Macintosh), or Chapter III-6, Exporting Graphics (Windows),

and Printing Graphs on page II-292 for information about maximizing the quality of printed graphs.

You can have as many graph windows open as memory allows. The amount of memory required for a

graph is proportional to the size of the graph and is also related to the number of colors displayed on your

monitor. In this age of cheap memory it is rare that the memory required for graphs will be a limiting factor.

The Graph Menu

The Graph menu contains items that apply only to graph windows. The menu appears in the menu bar only

when the active or target window is a graph.

When you choose an item from the Graph menu it affects the top-most graph; that graph will necessarily

be the “target window”.

For textboxes, legends and data tags.

For user defined buttons and

other controls.

Adds drawing tools palette to left of window.

Adds cursors info panel to bottom of window.
