Trend Lines

Trend lines lets you overlay graphs to compare and interpret data.

Like the Scatter Plot visualization, you can now set trend lines on a graph visualization to display the rate of change based on linear, exponential, power, or polynomial lines. The Trend Line feature allows you to overlay trend lines on a graph, most commonly over a Time dimension.

For example, in this graph comparison, we can see that Visits are trending up, but Orders are trending down.

To add a Trend Line

1. Open a graph and right-click the metric name in the upper left corner.

2. Click Trend Lines and select from the options.

   

   You can select the trend line to appear over the graph as Simple Linear, Exponential, Power, or Polynomial. Polynomial will create a polynomial regression trend line. Simple Linear will create a trend line as the rate of change along the regression line. Exponential calculates a trend line as y = b*exp( a*x ) and Power as y = b*x<sup>a</sup>.

   The trend will be calculated and rendered on the graph, and a callout will open displaying detailed information of the trend equation.
