When To Use A Bar Chart
Simplicity’s the key here. When you have categorical data, like your favorite coffee shop’s best-selling drinks or the monthly traffic on your blog, it’s bar chart o’clock.
Pinpoint the scenario where you need to compare these distinct categories or show some trends over time and bam, bar charts are your go-to.
It clicks when you’re presenting data and clarity’s the goal. Think about the audience too.
If they need quick, clean insights without the frills, bar charts deliver. It’s all about taking those figures and making them stick with minimal fuss.
How To Read A Bar Chart
- Identify the categories on the x-axis.
- Look at the y-axis for the scale or values.
- Observe the length or height of each bar.
- Compare the bars to understand the differences in values or frequencies between categories.
Types Of Bar Charts
Vertical Bar Chart
Traditional format with bars extending vertically from the x-axis. Good for comparing frequency or amount across categories.
Horizontal Bar Chart

Shows the total amount for each category and subdivides each bar to display the contribution of individual components to the whole.
Grouped Bar Chart (Clustered Bar Chart)
Places bars for different categories next to each other for easy comparison. Useful for comparing multiple sub-categories within each main category.
100% Stacked Bar Chart
Chart created with wpDataTables
Similar to the stacked bar chart but scaled so that each bar represents a percentage (100%), making it easier to compare the proportion of sub-categories within each main category.
Range Bar Chart

How To Make A Bar Chart In Excel
First things first, pick the data you wanna show off in your chart. Head over to the Insert tab, find the Charts group, and click on your chosen bar chart type.
If you’re rolling with just one column of numbers, your bar graph will show a single data series. Got more columns? Expect a color-coded party with each series in a different shade.
Now, Excel’s got a bunch of bar chart types. Clustered bar charts are great for comparing values across categories. Stacked bar charts? They’re all about showing how individual items stack up to the whole. And if you’re into percentages, 100% stacked bar charts have got your back.
Feeling artsy? Play around with the chart’s layout and style on the Design tab. Quick Layout and Chart Styles are your go-to buttons for this.
But wait, there’s more! Excel lets you tweak the bar width and spacing. Right-click a bar, hit Format Data Series, and adjust the Gap Width slider. Want your bars to overlap or have some space between them? The Series Overlap slider’s there for you.
Got negative values? No sweat. Excel handles them like a champ. You might want to move the vertical axis labels to the left and play with different colors for negative bars to make them pop.
And if your data’s looking a bit topsy-turvy, simply reverse the order of data categories or sort your bar graph without messing with your data.
How To Make A Bar Chart In Google Sheets
Creating a bar graph in Google Sheets? Piece of cake! Here’s the lowdown:
- Select Your Data: Grab the cells with the info you wanna show off.
- Hit the Chart Icon: It’s chilling in the Google Sheets toolbar.
- Customize Your Chart: Dive into the chart editor to make it your own.
Now, let’s jazz it up a bit. Want to label your bars? Click the three dots on your graph and hit “Edit chart.” You can add labels for clarity. And if you’re feeling fancy, customize those labels – change the font, size, color, you name it.
But wait, there’s more! Google Sheets lets you tweak your bar graph to the max. Play around with the chart style, axis titles, and series colors. You can even adjust the axis labels and gridlines.
Got a bunch of data? Stack it up with a stacked bar chart. Just choose your dataset, including headers, and select ‘Stacked Bar Chart’ in the chart editor. Want to show percentages? Go for a 100% stacked bar chart.
FAQ About Bar Charts
Why use bar charts?

Can a Bar Chart Show Continuous Data?
Eh, it’s not their prime gig. Bar charts are champs with categorical stuff – think “types of fruit” or “different brands.”
If you’re wrangling continuous data, like, say, heights or weights, you’d be better off with a histogram. It’s similar but built precisely for that kind of data.
What Should Be Considered When Creating a Bar Chart?
You’ll want to tune into things like the axis labels, bar colors, and spacing. Keep it clean and focused. Oh, and make sure your scale interval makes sense so your message doesn’t get lost in translation.

Are Bar Charts Effective for Large Data Sets?
They can be, but only if you’re not cramming a ton of bars into one congested space. It’s all about the clarity.
Big data? Consider breaking it down into smaller chunks or pivoting to another chart type. Keep it clean, or your story gets muddy quick.
How to customize a bar chart?
Customization involves adjusting axis labels, chart titles, color palettes, and bar lengths. Most chart software like Tableau or Excel offers extensive customization options. Adding data labels and chart legends can further enhance your data visualization efforts.
What is the difference between a bar and a histogram?
