Hi @todd.hoffman,
I just built a Gantt Chart using the approach given in your linked post, but I couldn’t add the dates to the axis.
One option would be to use free-form mode and overlay a line chart that only displays the week dates on its x-axis above the horizontal visual. Something like this for example
I see you’ve also tagged this post as a feature request for Gantt Charts, so keep an eye out here on the community for any future launch announcements.
Many Thanks,
Andrew
