![]() ![]() For example, you might specify the coordinates of a background shaded area to be in terms of a pair of axes. Unique to Igor is the ability to specify the coordinate system for draw objects. Multiple layers are provided and all tools may be used programatically. You can use Igor’s powerful drawing tools to annotate your graphs or page layouts with lines, arrows, rectangles, Bezier curves and many other types. You can even specify what happens for out-of-range data. Images can be true color or many different forms of false color. Speaking of flexible, Igor’s image plots can use any data type from unsigned byte to double precision complex (complex data is automatically presented as magnitude.) Pixels can even have uneven spacing as with a log axis or user specified x or y values. You can embed graphs within other graphs and can compose page layouts with multiple graphs, tables, annotations and pictures. You can create graphs with an unlimited number of traces, axes, contour plots, images and annotations. Igor’s 2D graphs are exceedingly flexible. Graphs automatically update to take full advantage of the available space when you resize a graph window. You can compose fancy text annotations called tags that dynamically update as the data changes or as you move a tag to a different data point. Igor’s cursors provide live readouts of your xy or image data and can be used to specify data subsets for analysis. And unlike some competitors, Igor always plots all of your data so you don’t miss features that others may skip. Graph updating is extremely fast allowing you to smoothly zoom in and out and pan in all directions even with millions of data points. Simultaneously, Igor’s graphs are exploratory tools of the first order. Virtually any graph you see in your favorite scientific or engineering journal could have been made using Igor - and many of them have been. Not only are many dash patterns provided, but you can also customize them with a graphical dash pattern editor. For example, line thickness may be specified as 1.35 Points - not just 1 or 1.5. Each element of a graph can be finely adjusted to meet your (or your journal’s) exacting requirements. Igor Pro is first and foremost a publication quality scientific and engineering graphics program. Wide-Angle Neutron Spin Echo Spectroscopy. ![]()
