Chapter II-12 — Graphs

II-251

Markers

If you choose the Markers or Lines and Markers mode you also get to choose the marker, marker size,

marker thickness, and whether the marker is opaque or not. The marker size is a fractional number from

1.0 to 9.0. It can also be set to 0 or “auto”, which chooses a marker size appropriate to the size of the graph.

The marker thickness is in points and can also be fractional. Setting the marker thickness to 0 makes the

markers disappear. The screen does not have enough resolution to show fractional points but they are

evident when you print the graph.

There is an interaction between marker size and marker thickness: Igor will adjust the marker size if this is

needed to make the marker symmetrical. The unadjusted width and height of the marker is 2

s+1 points

where s is the marker size setting.

Here is a table of the markers and the corresponding marker codes:

Markers 0-44 are compatible with Igor Pro 4. Markers 45 through 50 require Igor Pro 5.0 or later. Markers

51 through 62 require Igor Pro 6.1 or later and are available in new graphics only (see Graphics Technology

on page III-423). You can also create custom markers. See the SetWindow operation's markerHook key-

word.
