When to use bar graphs
A common question is when it’s best to use a bar chart instead of other types of diagram. Here’s some guidance.
Bar graphs vs pie charts
Pie charts are a good choice if you want to compare a small set of data to the whole. Bar graphs on the other hand are good if you have a larger number of data categories, particularly if there are small differences between them. For example, you could use a pie chart to visualize how different marketing channels contribute to overall business revenue (assuming the number of channels is not very large). Whereas a bar chart would be a better way to represent how much was spent on ads per month during the last year.
Bar graphs vs line charts
Line charts are ideal to show trends over time. The continuity of the line allows for better visualization of more subtle differences between periods. For example, the increase in revenue month on month. Line charts are not recommended for larger data sets, since it will make harder to compare groups of data.
Type of bar graphs
All bar charts can be categorized into 2 groups
Vertical bar charts
These are the most common type. They’re perfect for showing variations in sets of data and comparisons over time. In the example shown we can easily see how the sales evolve over the first four months of the year.
Horizontal bar charts
Nevertheless these have some benefits. For example, they’re easier to label, with more room for longer labels. Our example shows a series of marketing channels vs how much was spent on them.
Variations of the classical bar chart
Grouped bar charts: Can show data of different sub-groups of the same category. For example it could be used to group the same months of the year and compare each month, not just to other months that year but also to the same month of the previous year.
Stacked bar chart: Similar to the grouped bar chart but in this case the sub-groups are placed on top of each other in a way that makes it easier to compare both the total of the category and the sub-groups. For example it could be used to show how much was spent on different marketing channels month by month.

– Color of the bars, labels, legend, etc. You can personalize the color of every detail of your chart to ensure it perfectly fits the context

Tips for creating your bar chart
- Decide exactly what you want to show in your chart. Whether you’re creating your bar chart as part of a presentation for your next company meeting, or for a proposal that you’ll send to a client, you should always have a clear idea of the message you want to convey before you start.
- Prepare your numbers in a table or document so there are no mistakes.
- Log in to Xara Cloud and open the document in which you want to place your chart. If you haven’t signed up yet, you can take advantage of our free trial. If you want to use your chart stand-alone, and not in a document, you can open a blank template. You’ll be able to download your chart as a PNG, JPEG or SVG.
- Click on the plus symbol, select charts and select the kind of chart you want: Vertical or horizontal. Drag the chart and drop it on your document. It will automatically adopt your document colors.
- Change the sample values to your own. Also, make sure you change the sample labels to your own. You can do this by simply clicking on each text and value.
- Change the look and feel. Play with the handles to adjust the width and length of bars, spacing, rounded corners, etc.
- You can change the colors of your chart, but we recommend that you use the default ones since they will be consistent with the rest of your document.
What is a bar graph?
Although it’s more common to find vertical bar charts, you’ll also come across horizontal bar charts, and in fact they can be perfect to show a large number of entries in horizontal documents.
A bar graph is formed on two axes. If you’re looking at a vertical chart, the horizontal axis will show the data categories – this could be months or years, products, etc. On the vertical axis you’ll find the numerical values. The taller the bar, the bigger the amount.
The history of bar charts
The bar chart was invented by William Playfair at the end of the 18th-century. Playfair’s colorful career included working as a secret agent for Great Britain during the Napoleonic wars, so it’s somewhat disappointing to find that his first known chart showed the Exports and Imports of Scotland in 1781.
