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