Charts of DNA matches

Post by dichorionic »

I wonder if someone can help me. I have an unexplained DNA match, almost certainly a NPE, that I've been researching for a couple of years. Using Shared Matches and the Leeds technique I have narrowed down the options significantly. However, I would like to draw a chart limited to my DNA matches and their forbears to show my connections with them graphically. I don't want to print a tree of everyone in my antecedent four generations, just those of proven matches. I have applied both the DNA Marker to every match as well as a custom DNA Flag. Is there a way to limit a chart to the matches?

I asked about this a bit back. It seems the only way to do it is to make a copy of the project and delete all the individuals you don't want in the chart to leave just the ones you want.

Thank you John. Ye gods! Time to get out the ruler and coloured pencils.

I have a custom attribute, DNA match (Ancestry), where the value is the relationship with myself, and a custom diagram where the box is coloured yellow if this fact is present, and green where the individual is a Most Recent Common Ancestor witness to that fact as per the recent discussion. I then produce a diagram starting with the relevant Most Recent Common Ancestor(s), and manually hide all the boxes relating to branches that have no match. Finally, I save it using Diagram > Save Diagram As... > Family Historian Chart..., with one chart per common ancestor.

An example of the final product is shown below. This public version uses a fully redacted text scheme that shows only the DNA match value, but it can of course contain any detail that you wish.

It can take a few experiments to configure it as you require, but is that worth trying?

This is the problem with what I wanted to achieve and I think what dichorionic wanted:

Basically what I wanted was a combined chart similar to how related with siblings hidden for all my MRCA and DNA matches.

Generalising, has anyone ever suggested a new chart option formatted like all relatives but only including those individuals in a list? That would be useful for more than just charting DNA matches.

Years ago I once used Diagram > Selection&Marks to mark specific boxes in a diagram and then only show them with the help of Diagram > Hide/Show Boxes. I don't remember exactly how I did that, but maybe you'd want to play around a bit with it, using a custom attribute for DNA and then a query working with it. This could also be done with an "all relatives" diagram.
