Tableau Tip: How to Create DNA Charts

The Data School launched this week and on the consultants' second day, we brought them into an all day training class with the rest of the Information Lab team. One of the courses we taught was advanced visualisations. The reason we run these internal training classes is because we have a core belief in continuous learning.

As part of this exercise, we were building a dot plot and Laszlo Zsom asked how to connect two dots on the same row.  I hadn't ever done it before, so I used a Gantt chart to connect them. Then Chris Love suggested using lines.

In this week's tip (two days late as it is), I demonstrate both of these methods.  Click on the image below to enjoy the video.
