Igor Pro's 2D graph types include highly customizable X-Y (line, marker, area and bar) plots, contour, image, and category plots. As illustrated by the graph to the right, you can combine any or all of these forms in a single graph window. Igor places no limits on the number of graph objects or the size of your data.

In Igor, as you expand or shrink a graph window, the graph automatically takes full advantage of the available space, expanding or shrinking font, marker and line thickness to optimum values approprate for the new size. Of course, you can force a graph to specific size or aspect ratio and can override automatic adjustments.

Igor's annotation dialog enables you to create arbitrarily complex text boxes, legends (including color scales) and dynamic tags that can automatically present data values. Dynamic tags can not only be attached to points on an XY plot but can even be attached to pixels on an image plot. Tags can be set to automatically rotate tangent to the point on the curve to which they are attached.
