Scale Marker Size in Axis Units
Wed, 05/13/2020 - 01:10 pm
The attached zip archive contains a procedure file and a demo experiment that allow you to display a trace using markers where the size of each marker is controlled by a wave whose values are scaled in units of one of the axes.
In this application, we have X and Y waves and a wave containing a radius for each XY pair. We want to display a marker, such as a circle, at each XY location with the size of the marker controlled by the radius wave. The radius wave data is scaled in terms of one of the built-in axes: left, right, bottom, or top.
This version is for Igor Pro 6.37 through 8.0x. A different version will ship with Igor Pro 9.00 and later.
To try it, download and unzip the attached zip file. Copy the "Scale Marker Size in Axis Units.ipf" procedure file to your "Igor Procedures" folder. Copy the "Scale Marker Size in Axis Units Demo.pxp" file to anywhere on your hard disk. Run Igor and open the demo experiment file.
