In healthcare, bubble charts can be life-savers (literally). For instance, they might analyze sales, profits, and market share all in one fell swoop! Healthcare Heroes Business BrillianceĬompanies can spot trends, make projections, and see which areas need a bit of spit and polish. Life's too short to make bad decisions, and bubble charts can be the ace up your sleeve in various realms. Bubble Charts in Action: Real-Life Applications Visual Oomph: Bubbles add a dash of pizzazz that’s not just aesthetically pleasing but also adds layers of information. Dimensions Galore: Scatter plots are plain Janes with two sets of data, whereas bubble charts are like Swiss Army knives, packing in three or more data sets. "Aren't bubble charts just glorified scatter plots?" you may ask. It’s like a double whammy! Bubble Charts vs. Simple as pie! - Color: When feeling snazzy, bubbles can change color to show even more data. Size: The bigger the bubble, the larger the value it represents. Let's not beat around the bush the bubbles are where the action is! They’re like chameleons, changing size (and sometimes color) to represent different data values. Their size, and sometimes color, represent additional data points. Bubbles: These circles are the showstoppers. Y-axis: This vertical axis is the sidekick, showing the effect or dependent data. It's the head honcho that calls the shots. X-axis: Typically the horizontal axis, this is where you'll plot data that’s independent or a cause. Just like how behind every great person, there’s a great behind-the-scenes crew, behind a mesmerizing bubble chart lies a cast of characters: the X-axis, Y-axis, and the bubbles. It’s like your regular scatter plot, but on steroids! The Nuts and Bolts of Bubble Charts A Three-Ring Circus: Axes & Bubbles The X and Y axes represent two sets of data, while the size and sometimes even the color of the bubbles add extra layers of info. Fields are listed by table or folder.In the buzzing hive of data visualization, there's one sweet treat that’s as eye-catching as it is insightful - Bubble Charts! A bubble chart is a nifty multi-dimensional visualization tool that goes the extra mile by showcasing not just two, but three (or more) sets of data in one go. Note: In Tableau 2020.2 and later, the Data pane no longer shows Dimensions and Measures as labels. For more information, see Color Palettes and Effects. To further develop this view, you might edit the colors for Profit to show negative profit in a different color, or create a calculated field to shows profit divided by sales (that is, profit margin) and then drop that on Color instead of absolute profit. The color of the bubbles shows the profit (the darker the green, the greater the profit).įor information about formatting mark labels, see Show, Hide, and Format Mark Labels. The size of the bubbles shows the sales for different combinations of region and category. Next we'll add another layer of information to the view.ĭrag Region to Label on the Marks card to clarify what each bubble represents. Tableau displays the following packed bubble chart:ĭrag Region to Detail on the Marks card to include more bubbles in the view. Tableau displays a bar chart-the default chart type when there is a dimension on the Columns shelf and a measure on the Rows shelf.Ĭlick Show Me on the toolbar, then select the packed bubbles chart type. Measure is aggregated as a sum and a vertical axis appears. To create a basic packed bubble chart that shows sales and profit information for different product categories, follow these steps:Ĭonnect to the Sample - Superstore data source.Ī horizontal axis displays product categories. The basic building blocks for a packed bubble chart are as follows: Mark type: Dimensions define the individual bubbles, and measures define the size and color of the individual circles. Use packed bubble charts to display data in a cluster of circles.
