How to Visualize Salary Ranges in Google Slides Using a Box Plot

Ever tried presenting compensation data to the executive team and watched their eyes glaze over?

You throw up a standard bar chart showing "Average Engineer Salary: $115,000." Almost instantly, someone interrupts. "But what's our ceiling? Are we underpaying our junior staff? What about that one guy we hired from Google?"

Averages lie. Or at least, they only tell half the truth.

When you're dealing with salary bands, you don't just need a single number. You need to show the whole spread: the minimums, the maximums, where the bulk of your team actually sits, and those couple of high-earning outliers.

You need a box plot.

Why Box Plots Are the Ultimate HR Tool

If you aren't familiar with them, box plots (or box-and-whisker charts) look a bit like a stock market ticker. But for HR and hiring managers, they are absolute magic.

Here is what a single box plot tells your audience at a glance:

• The Box: Shows where the middle 50% of your salaries fall. This is your core compensation band.
• The Line Inside: The median salary. Exactly half your team makes more, half makes less.
• The Whiskers: The realistic minimum and maximum ranges you pay for that role.
• The Dots (Outliers): That one superstar you paid double to poach from a competitor.

It packs five different data points into one clean visual.

The Google Slides Problem

There's just one massive catch. Try finding a box plot in standard Google Slides.

Spoiler: it doesn't exist.

If you use the native tools, you usually end up wrestling with stacked bar charts, making certain segments transparent, and wasting three hours just to create something that looks vaguely like a whisker. It's frustrating, and worse, it breaks the second you need to update the numbers.

I'm going to show you a better way. We're going to build a presentation-ready box plot directly inside Google Slides, and it's going to take about two minutes.

How to Build a Salary Box Plot with ExtraChart

Instead of hacking together shapes, we use ExtraChart. It's an add-on I rely on heavily because it gives Google Slides the advanced charting capabilities it desperately lacks, all without leaving the presentation.

Here is how to set it up:

1. Launch the Editor

First, open your presentation. Go to Extensions -> ExtraChart -> Create & Edit Charts. The ExtraChart sidebar will slide open on the right.

2. Select the Box Plot

You'll see a categorized list of 20 different professional charts. Scroll down to the Business & Analytics section and click the Box Plot icon.

3. Drop in Your Salary Data

Clicking the icon opens a popup editor with a split view. On the left, your real-time preview. On the right, a built-in spreadsheet.

You don't need to manually type everything out. Just open your Excel file, CSV, or Google Sheet containing your salary data, highlight the rows, and paste them straight into the ExtraChart data tab. The chart on the left will instantly snap into shape, calculating your quartiles and medians automatically.

4. Style It for the Boardroom

Nobody wants a generic-looking chart in a high-stakes meeting. Click over to the Settings tab.

Here, you can adjust the padding, change the fonts to match your company's brand guidelines (I usually stick to Inter for modern presentations), and set custom hex codes. You can even toggle gridlines to make the salary intervals crystal clear.

5. Insert and Update Later

Once it looks perfect, click "Create." ExtraChart drops a high-resolution, completely private image of your box plot right onto your slide.

But here is my favorite part, and why I stopped pasting screenshots from Excel. Next quarter, when HR updates the salary bands, you don't have to start over. Just click the box plot image on your slide, re-open ExtraChart, and it remembers all your data and settings. Update the numbers, and you're done.

Stop Hiding Your Data

Salary transparency and compensation analysis are too important to hide behind a flat average.

By switching to box plots, you give your leadership team the actual context they need to make hiring and retention decisions. Give ExtraChart a try on your next compensation review deck—you get 10 free charts a month to play with—and see how much faster those meetings go when everyone can finally see the whole picture.
