This topic describes the types of scatter charts and their examples.

A scatter chart is often used to display the relationship between the values of variable X and those of variable Y. In a line chart, the X-axis represents different categories. In a scatter chart, the X-axis represents the values of a variable.

A scatter chart consists of a horizontal value axis for variable X and a vertical value axis for variable Y. It combines the values of variable X and those of variable Y to data points and shows them in irregular intervals or clusters. A scatter chart is typically used to show and compare numeric values in scientific, statistical, and engineering data.

You can use a scatter chart to compare values of typically two variables from five dimensions. The color, label, or size of each data point can be used to represent a dimension of values.

You can use a scatter chart to find out the relationship between variable X and variable Y.

Scatter chart with smooth lines and markers

A scatter chart with smooth lines and markers displays smooth curves that connect data points.

Bubble chart

A bubble chart is a variation of a scatter chart. In a bubble chart, bubbles represent data points and the size of the bubbles represents an additional dimension of data. Similar to a scatter chart, a bubble chart consists of a horizontal value axis for variable X and a vertical value axis for variable Y. Different from the scatter chart, the bubble chart also displays the values of another variable, variable Z, which represents the size of the bubbles.

If your data contains three data series and each series contains a set of values, you can use a bubble chart instead of a scatter chart to display the data. The size of the bubbles is specified by the values in the third data series. A bubble chart is typically used to display financial data. The bubbles in different size bring strong visual impact.
