Custom Shapes allows you to add an extra dimension to your visualisation and have the benefit of being very easy to do. As such, in this quick tip, we are going to spend 10 minutes talking about where you can find icons and how you can make them accessible in Tableau.
Note: Custom shapes can also create confusion and subtract away from your data visualisation, so please use when appropriate.
To add shapes is a very easy thing to do in Tableau.
- Locate the My Tableau Repository directory.
- Within the directory, there should be a folder called Shapes.
- Create a new folder called Custom Shapes.
- This is where we are going to put our shape image files.
We are going to have some fun and download a few shapes and save them into this folder for usage within Tableau.
You can always create your own custom shapes, however, there are quite a few websites out there that provide images for you to use:
- Go to http://fa2png.io
- In the configuration box:
- Search for wi-day-cloudy.
- Set the Color of the icon to #000000.
- Leave the Background of the icon as transparent.
- Leave the Size of the icon as 256px.
- Leave the Margin of the icon as 0px.
- Click on Generate.
- After the image has been generated, click on Download, to save this image.
- Repeat the above for the following icons:
- Copy these files into your Custom Shapes folder.
Note: Font Awesome gives you scalable vector icons that can instantly be customized — size, color, drop shadow, and anything that can be done with the power of CSS. I use this often in my websites and this site allows you to download the png version. This site also has plenty of other web icon libraries for download.
Copy the following data set and load this into Tableau Desktop / Public.
Weather, Days of Year Cloudy, 80 Fog,100 Rain,120 Sunny,65
Once the data is loaded, we are going to build our worksheet:
- Change the Mark Type to Shapes.
- Drag Weather onto the Color Mark.
- Drag Weather onto the Shape Mark.
- Drag Days of Year onto the Size Mark.
- Drag Days of Year onto the Label Mark.
- Click on the Shape Mark.
- Click Reload Shapes to ensure that your shapes are loaded into Tableau.
- In the Select Shape Palette choose Custom Shapes.
- Now assign the Shapes to your Weather Dimensions by matching the text in Select Data Item to your custom shapes.
- The click apply.
You want something like the following:
Your worksheet will now look like the following:
Yep, I am from London and we do not have enough sunny days each year, this is fake data, but jokes aside, we can leverage any shapes that we can get out hands on. Use this Tableau Quick Tip (QT) responsibly and have loads of fun.
