Displaying a linear trendline

Cloudera Data Visualization enables you to create a linear trendline. A linear trendline is a best-fit straight line that is used with simple linear data sets. The data is linear if the system data points resemble a line. A linear trendline usually shows that something is increasing or decreasing at a steady rate.

To display a linear trendline for the graph, navigate to the Trendline menu, and select Display linear trendline.

Note that the trendlines appear on the visual. To see the specific values related to the calculation of the trendline, hover your mouse over the trendline and examine the information in the Tooltip window.
