Choosing the right chart type
Use a bar chart to compare amounts between categories, a line chart to show change over time, and a pie or doughnut chart only to show parts of one whole - and with no more than five or six slices.
Type your data one row per line as a label and a value, such as "March, 150". Keep the title short and specific, start bar charts at zero, and sort bars from largest to smallest when the order does not matter.

Frequently asked questions
Bar and line charts work well for comparing values or showing trends over time. Pie and doughnut charts work best for showing proportions of a whole (like percentage breakdowns) with a limited number of categories.
Typically enter labels and corresponding values directly into the tool's input fields, which then get plotted according to your chosen chart type.
Yes - most chart makers let you adjust colors and some styling options so the chart matches your presentation or brand needs.
Give it a clear title that states the takeaway, label the axes with units, use one highlight colour for the point you want noticed and remove gridlines and legends that add nothing.
When there are more than about five slices, when values are close together, or when you want to compare across time. A bar chart shows small differences much more clearly.
Yes. Bars represent amounts by their length, so a cut-off axis exaggerates differences. Line charts can start elsewhere when the trend matters more than the absolute value.
