Hi @AsymptoticRules,
An other solution would be to use the Variability Chart from the Analyze>>Quality and Process menu.
Starting from the Stacked table from the example from Victor, here is the plateform configuration.
This gives you the following chart, close to yours.
In the hotspot of the Variability Gauge Analysis, activate the option "Connect Cell Means" to get the following chart
In case you want to separate the charts, you jus need to unselect the options "Show Points" and "Show Range bars"
Hope this will help you,
