Chart tracing tool

This is probably one of the most useful utilities in Antenna Magus. It started as an in-house application used by the engineers to read off design values from scanned graphs (mostly from published papers that were only available in *.pdf or in hardcopy). After showing this to other engineers and seeing their excitement we decided to include this as a utility in Antenna Magus.

Simply select your scanned graph image, specify anchor values and follow the trace(s) with your mouse. Apply the spline or linear function and export the XY values to a TSV (tab sperated values) file. It supports both polar and cartesian graphs.

While the chart is being traced, values relevant to the indicated data type are automatically extracted, making it easy to determine quantities such as bandwidth, sidelobe level etc. of the data. These values can then in turn be used for design or specification refinement.

Watch the movie below to see how nicely it works.
