## Which is better line chart or pie chart?

Line graphs can also be used to compare changes over the same period of time for more than one group. . . . a Pie Chart. Pie charts are best to use when you are trying to compare parts of a whole.

## When should you use a line graph VS bar graph?

Line graphs are useful for displaying smaller changes in a trend over time. Bar graphs are better for comparing larger changes or differences in data among groups.

**Why is a pie chart better than a line graph?**

Line graphs are used to show trends over time. A pie chart shows the relationship of categories in regards to the whole.

### Which type of chart will be most effective?

Line charts are the most effective chart for displaying time-series data. They can handle a ton of data points and multiple data series, and everyone knows how to read them.

### What are the main differences among line bar and pie charts?

You would use:

- Bar graphs to show numbers that are independent of each other.
- Pie charts to show you how a whole is divided into different parts.
- Line graphs show you how numbers have changed over time.
- Cartesian graphs have numbers on both axes, which therefore allow you to show how changes in one thing affect another.

**When would you use a pie graph?**

Pie charts are often used in business. Examples include showing percentages of types of customers, percentage of revenue from different products, and profits from different countries. Pie charts can be helpful for showing the relationship of parts to the whole when there are a small number of levels.

#### Which is the main use of line graph?

Line graphs are used to track changes over different periods of time. Line graphs can also be used as a tool for comparison: to compare changes over the same period of time for more than one group.

**How do you know which chart to use?**

Bar charts are good for comparisons, while line charts work better for trends. Scatter plot charts are good for relationships and distributions, but pie charts should be used only for simple compositions — never for comparisons or distributions.

## When would you use a pie chart?

A pie chart is best used when trying to work out the composition of something. If you have categorical data then using a pie chart would work really well as each slice can represent a different category. A good example of a pie chart can be seen below.

## What is the difference between pie chart and bar chart Why do we use them?

In short, a pie chart can only be used if the sum of the individual parts add up to a meaningful whole, and is built for visualizing how each part contributes to that whole. Meanwhile, a bar chart can be used for a broader range of data types, not just for breaking down a whole into components.
