This tutorial explores Tableau Public's new Radial Charts feature, currently available in a trial until June 30th. Radial Charts allow you to create multi-level pie charts, offering a unique way to visualize hierarchical data.
To create a Radial Chart, start by dragging the subcategory field onto the level. Next, add the segment field onto the level field, and you will see a second level appear around the outside of the chart. The order in which you place these fields dictates the order of the sections in the chart.
The colour of the chart is dictated by the first field you drag into it. Currently, the colour palette seems to be uneditable, which might be a limitation during the trial. To show the correct proportions of the categories, add the quantity field onto the angle field.
Unfortunately, the current trial version has some limitations and potential bugs, such as unresponsive clicking and hovering over certain sections. Additionally, the feature doesn't offer the same flexibility in labeling and colouring as a traditional pie chart.
Despite these limitations, Radial Charts provide a more straightforward way to create multi-level radial charts compared to previous workarounds, such as layering multiple pie charts or using map layers tricks.
Remember, this feature is in beta until June 30th, so give it a try on Tableau Public and explore its potential for your data visualization projects! Stay tuned for more updates and tutorials on new Tableau features.
