How to Create a Nightingale Rose in Tableau Desktop 10.1 Download

Are you looking for a unique way to visualize your data? Look no further than the Nightingale rose, also known as a polar map or circular histogram. This chart type is perfect for summarizing and analyzing data across multiple categories. In this article, we'll show you how to create a Nightingale rose in Tableau Desktop 10.1 download.

To start, import your data source into Tableau Desktop and create a bucket of Path fields. Then, drag the Path (data bucket) into the path of the tag card, followed by X into the column and Y into the row. Right-click on the Path to display missing values.

Next, you'll need to create eight calculated fields:

1. Edges: used to calculate the angle

2. Angle: calculated field using WINDOW_MAX()

3. Count: calculates the number of slices

4. Number of Slices: calculated field using WINDOW_MAX()

5. Radius: calculated field using SQRT(AVG()/PI())

6. Index: used to calculate X and Y axes

Once you have created these calculated fields, it's time to start building your Nightingale rose.

Step 1: Prepare the data structure by creating a data bucket of the Path field.

Step 2: Create a calculated field INDEX(), named Edges, which is used to calculate the angle. Then, create a calculated field (-1)*(2*PI()/WINDOW_MAX()) and name it Angle.

Now that you have your calculated fields set up, it's time to start building your chart. Drag Data into the color and display it as a month, followed by Product Category into the detail and convert it to a color. Select the shape as Polygon, then load the Path into the row.

Finally, create a calculated field INDEX(), named Count, to calculate the number of slices. Then, create the calculated field WINDOW_MAX() and name it Number of Slices.

The result is a beautiful Nightingale rose that showcases your data in a unique and visually appealing way. With this chart type, you can easily compare the differences between different types (multi-angle analysis) and reflect the size of each item (higher proportion of items).

In conclusion, creating a Nightingale rose in Tableau Desktop 10.1 download is easier than you think. By following these steps, you can create a stunning visual representation of your data that will impress anyone who sees it.
