![]() Absolute: coordinates are measured in points relative to the top-left corner of the window.This capability is especially useful in graphs to allow your drawings to adjust to changes in window size or to changes in axis scaling. You can choose different systems on an object-by-object basis and for X and Y independently. Polygon and Bezier objects can use dashed lines, have a fill color and pattern and can have arrow heads.ĭouble-clicking on an object leads to a dialog where the object’s properties can be adjusted.Ī unique feature of Igor’s drawing tools is the ability to choose different coordinate systems. Alignment for adjusting the drawing order, object positions, group and ungroup objects, and perform other object movement tasks.Draw environment for changing properties such as line thickness, color, fill pattern, and other visual attributes.The Polygon tool is also used when graphically editing data. Arrow tool for selecting, moving and resizing objects.The drawing tools are available in page layout, graph and control panel windows. Although only programmers can create such packages, everyone can make use of them. This allows programmers to create packages of code that add new graph types to Igor’s repertoire. Like all other aspects of Igor, drawing tools are fully programmable. In control panel windows, you can use the drawing tools to create a fancy background for controls. ![]() You can also create new waves by simply drawing them. You can graphically edit a wave’s data values when it is displayed in a graph data points can be deleted, added or modified. For example you can specify that a line thickness be 0.76 points. All line sizes and object coordinates can be specified using real numbers. These drawing tools are object-oriented and optimized for the creation of publication quality graphics. Igor Pro®’s drawing tools are useful in page layout and graph windows for highlighting material with boxes, circles and arrows and can also be used to create diagrams. ![]() Wide-Angle Neutron Spin Echo Spectroscopy. ![]()
