How to Remove Gridlines in Tableau
Gridlines in Tableau can sometimes feel like a well-meaning friend who just doesn't know when to leave a party. They are there by default to provide context, but they can easily clutter your visualization and distract your audience from the story your data is telling. This guide provides a clear walkthrough of everything you need to know to remove gridlines, axis lines, zero lines, and other pesky chart lines in Tableau for a cleaner, more professional dashboard.
Why Remove Gridlines in the First Place?
Before jumping into the "how," it's worth understanding the "why." While gridlines seem helpful, experienced analysts often remove them to improve their visualizations. Here are a few key reasons:
- Improved Data-to-Ink Ratio: A core concept in data visualization is maximizing the "data-ink" - the pixels used to display the actual data - and minimizing everything else. Gridlines are non-data ink. By removing them, you make your data points, bars, or lines the undeniable stars of the show.
- Reduced Visual Clutter: Every line you add to a chart increases its cognitive load, the mental effort required for your audience to understand it. A clean, minimalist design is easier to interpret at a glance. When the focus is on a trend or comparison, dense gridlines just get in the way.
- Enhanced Professionalism: Polished, publication-ready charts often use a clean design. Removing unnecessary lines signals intentionality and gives your dashboard a more deliberate, polished aesthetic. Your goal isn't just to show data, but to present it effectively.
Think of it this way: if your data is the lead actor, gridlines are the extras in the background. Sometimes you need them to set the scene, but most of the time, the story is stronger when the focus is purely on the main character.

The Central Hub for Line Formatting: The Format Pane
Tableau centralizes almost all of its visual formatting options in one convenient place: the Format pane. Instead of hunting through different menus, you can handle nearly all line removal from this single hub. Getting comfortable with this pane is the fastest way to master visualization styling.
Here’s how to open it:
- On your worksheet, right-click anywhere on the empty space of your chart (not directly on a data mark like a bar or a point).
- From the context menu that appears, select Format....
That's it! The Format pane will now open on the left side of your workspace. By default, it might open to the Font formatting options. At the top of this pane, you'll see a row of icons:
- Font (Aa): Controls text styles.
- Alignment (aligned lines icon): Controls text positioning.
- Shading (bucket icon): Controls background colors and banding.
- Borders (grid icon): Manages the borders around headers, cells, and panes.
- Lines (wavy line icon): This is our primary target. It controls gridlines, zero lines, trend lines, and axis lines.
For removing gridlines, we'll spend nearly all our time in the Lines and Borders sections.
A Step-by-Step Guide to Removing Every Line
With the Format pane open, let's systematically eliminate all the unwanted lines from your view. Click on the Lines icon (it looks like a wavy line) at the top of the pane to get started.
1. Attack the Main Gridlines (Sheet Tab)
The Sheet tab in the format menu controls the lines that span across the main body of your visualization. This is where you’ll handle the most common culprits: gridlines and zero lines.
- Grid Lines: This dropdown is your main weapon. By default, it's often set to a thin, gray line. Click the dropdown and select None. This will remove the primary horizontal and vertical lines that form the grid in your chart's background.
- Zero Lines: These lines specifically indicate the zero mark on an axis. They are especially common in bar charts showing both positive and negative values. Even after removing main gridlines, the Zero Line often remains. Find the "Zero Lines" dropdown under the "Grid Lines" option and change it to None.
2. Clean Up the Axes (Rows & Columns Tabs)
Next up are the lines directly connected to your axes. These are managed in the Rows and Columns tabs within the same Format Lines menu.
- Rows Tab: This controls the formatting for everything originating from the vertical (Y) axis.
- Columns Tab: This does the exact same thing for the horizontal (X) axis.
Checklist for a Line-Free Chart
Feeling overwhelmed? Here’s a quick-reference checklist to follow every time:
- Right-click the chart and select Format.
- Click the Lines icon.
- In the Sheet tab:
- In the Rows tab:
- In the Columns tab:
Troubleshooting: The Gridlines Won't Go Away!
Sometimes you follow all the steps above, but stubborn lines refuse to disappear. This is usually because the line is actually a border, not a gridline. Luckily, the fix is in the same area.
Problem: Faint Lines Between Bars or Panes Remain
If you see residual lines dividing your visualization into sections, they are probably borders.
- The Fix: In the Format pane, click the Borders icon (the grid box). These settings control the outlines of different chart sections.
- Under the "Sheet" tab, find the Row Divider and Column Divider dropdowns.
- Set both the "Pane" section to None. This cleans up any interior dividing lines. In most cases, this takes care of the remaining clutter.
Problem: Extra Lines from Trend or Reference Lines
If you've previously added a trend line, reference line, or forecast, it will not be affected by the gridline formatting settings. These are analytical objects layered on top of your chart.
- The Fix: Removing these is straightforward. Simply right-click directly on the line itself and choose Remove. You can also re-format them by selecting Format... to change their color or style to be less intrusive.
Smarter Formatting: When Not to Remove Lines
While removing all lines creates an ultra-clean look, it's not always the best choice. Some visualizations, especially larger tables or complex plots, benefit from subtle guidance.
Instead of turning everything off, consider these alternatives:
- Lighten Up: Instead of selecting "None," choose the lightest possible gray color and the thinnest solid line style. This provides just enough structure to guide the eye without adding visual noise. A faint, unobtrusive line is often better than no line at all.
- Go Dashed: A thin, dashed, or dotted line is another excellent way to reduce visual weight. Dashed lines feel less "final" and "heavy" than solid lines, making the data stand out more clearly.
- Use Shading Instead of Lines: Go to Format > Shading and apply subtle row or column "banding." This adds alternating light gray stripes to the background, which helps readers track across a wide table or chart without needing any lines at all.
The goal is intentionality. Every element in your visualization should have a clear purpose. If a line is not actively helping your audience interpret the data, it's probably hurting them.
