How to Add Icon to Tableau Dashboard

A wall of numbers is good for analysis, but it's terrible for quick comprehension. That's where icons come in. Adding simple visual cues to your Tableau dashboard can instantly transform it from a dense data summary into a clear, intuitive reporting tool. This article will show you three effective methods for adding icons to your dashboards, from the most flexible data-driven approach to a quick and simple trick for static visuals.

Why Use Icons in Tableau Dashboards?

Before we get into the "how," let's quickly cover the "why." Strategic use of icons does more than just make your dashboard look nice, it serves a functional purpose.

• Faster Cognition: Our brains process images far faster than text. A green up-arrow next to a sales number is understood instantly, while reading "Sales increased by 15% period-over-period" takes a moment longer. For Key Performance Indicators (KPIs), this instant recognition is invaluable.
• Improved User Experience (UX): Icons act as signposts, guiding your audience's attention to the most important metrics. They break up monotonous grids of text and numbers, making the dashboard less intimidating and more engaging to interact with.
• Brand Consistency: Using company logos, product icons, or branded visual elements reinforces your organization's identity, especially on dashboards shared with clients or external stakeholders.

Method 1: The Best Way - Using Custom Shapes

This is the most powerful and common method for adding icons that change dynamically based on your data. You can associate specific pictures with different values or calculations. Want a green checkmark for goals met and a red 'X' for those missed? This is the method for you.

Step 1: Get Your Icon Files Ready

First, you need the actual image files for your icons. You can get these from many places - a company brand kit, a graphic designer, or icon websites like Flaticon, The Noun Project, or Font Awesome.

A few tips for your icons:

• Use a consistent style. Don't mix and match different visual styles. If you use line art for one icon, use it for all of them.
• Stick to PNG format with a transparent background. This ensures your icon blends seamlessly into your dashboard without an ugly white box around it.
• Keep them small. Icons should be helpers, not the main event. Small file sizes also keep your dashboard loading quickly. A size around 50x50 or 100x100 pixels is usually plenty.

Step 2: Add Icons to Your Tableau Shapes Folder

Tableau needs to know where to find your custom icon files. It looks for them in a specific folder within your "My Tableau Repository" that was created on your computer when you installed Tableau.

1. Navigate to your repository. This is typically found in: Documents/My Tableau Repository/Shapes
2. Inside the Shapes folder, create a new sub-folder. Name it something descriptive, like "KPI Icons" or "My Custom Icons." This folder name will appear in Tableau's interface.
3. Move or copy your prepared PNG icon files into this new folder.

Step 3: Tell Tableau How to Use the Icons

Now, let's switch over to Tableau Desktop. First, if Tableau was already open when you added the icons, you need to tell it to check the folder again. In any worksheet, click the drop-down on the Marks card, select Shape, then click More Shapes..., and finally click the Reload Shapes button. Now Tableau knows about your new icons.

The key to making icons dynamic is to create a calculation that tells Tableau which icon to use based on your data. Let's build a common example: showing an up or down arrow based on profit margin.

1. Create a Calculated Field. Go to Analysis > Create Calculated Field. Let's name it "Profit KPI."
2. Write a simple IF/THEN statement. This calculation will output a text label that we’ll later link to an icon.

IF SUM([Profit Ratio]) > 0.15 THEN 'Good' ELSEIF SUM([Profit Ratio]) > 0 THEN 'Okay' ELSE 'Bad' END

This formula checks the profit ratio. If it's above 15%, it labels it "Good." If it's between 0% and 15%, it's "Okay." If it's negative, it's "Bad."

1. Bring It All Together:

That's it! You now have a worksheet where the icon changes automatically as your data updates. You can place this worksheet on your dashboard to serve as a dynamic KPI indicator.

Method 2: The Easiest Way - Floating Image Objects

Sometimes you don't need a dynamic icon. You just need to place a static image on your dashboard, like a company logo, a watermark, or an information icon that links to a help page. In this case, the Image Object is your best friend.

1. Go to your desired dashboard in Tableau.
2. In the Objects panel on the left (at the bottom), find the Image object.
3. Before you drag it, make sure the Floating option is toggled on at the top of the Objects panel. This lets you place the image anywhere you want, on top of other elements.
4. Drag the Image object onto your dashboard canvas.
5. A dialog box will appear. Click Choose... to browse your computer for the image file (JPG, PNG, etc.).
6. After selecting your image, you can check boxes to Fit Image and Center Image within the object's borders. You can also specify a URL to open when a user clicks the image.
7. Click OK. You can now resize and position the floating image object anywhere you need it on the dashboard.

Method 3: The Clever Way - Using UNICHAR and Symbols

This is a lesser-known but brilliant method that doesn't require any image files. You can use text symbols like ●, ■, ▲, and ▼ by leveraging special fonts and a simple Tableau function. It's fast, neat, and keeps your workbook lightweight.

The magic here is the UNICHAR() function, which lets you insert a specific Unicode character into a text field.

1. Create a Calculated Field. Let's make an indicator for sales performance vs. a parameter-based goal. Call it "Sales Symbol."
2. Use an IF/THEN statement with the UNICHAR() function. You'll need to find the Unicode number for the shapes you want. For example:

IF SUM([Sales]) > [Sales Goal Parameter] THEN UNICHAR(9650)
ELSE UNICHAR(9660)
END

1. Drag this new "Sales Symbol" calculation onto the Text property on the Marks card. You'll see the appropriate triangles appear.
2. Add Color. To make it even more effective, drag your original SUM(Sales) or a new KPI calculation onto the Color property. Set the color palette to be "Stepped" with 2 steps. The up-arrows will be one color (e.g., green), and the down-arrows will be another (e.g., red).

This method is excellent for simple, clean indicators like direction arrows, bullet points, or KPI status dots directly beside your numbers in a table.

Final Thoughts

Mastering the use of icons can significantly improve the clarity and impact of your Tableau dashboards. Whether you use the robust Custom Shapes method for dynamic, data-driven visuals, the simple Floating Image object for logos, or the clever UNICHAR function for lightweight symbols, you're making your data easier to understand at a glance.

Of course, building these views in Tableau still involves an investment of time, from preparing your data to configuring calculations and assigning shapes.
