Roberta Estes writes in her blog 4 March 2018 https://dna-explained.com/2018/03/04/rootstech-day-3-jewish-dna-schmoozing-and-the-flapper-party/ keep scrolling to get to (the part on charts) . . . I came to RootsTech with a list of vendors that I absolutely wanted to see and meet. Pierre Cloutier who wrote Charting Companion <https://progenygenealogy.com/Products/Family-Tree-Charts> was one of those people. I’ve used this product for years to produce great charts and reports. It works with almost any genealogy software Here, Pierre’s explaining the McGuire Method to a visitor. I wasn’t quite sure how he could have implemented this methodology, so he kindly explained it to me. Charting companion now includes special mtDNA lineages <https://dna-explained.com/2017/02/07/using-x-and-mitochondrial-dna-charts-by-charting-companion/> displayed on charts, X chromosome inheritance <https://dna-explained.com/2014/02/03/charting-companion-from-progeny-software/> as well as the new McGuire methodology <https://thegeneticgenealogist.com/2017/03/19/guest-post-the-mcguire-method-simplified-visual-dna-comparisons/> . If you’re trying to figure out where a DNA tester places in a group of other testers, the McGuire Method will be helpful, and Pierre has automated this methodology. Thank you, Pierre!
