You can drag the equation and the correlation box to change its position on the point cloud.Įxcel also includes linear regression functions with which you can find slope, intercept, and r-squared values with for y and x data arrays. This adds r squared to the graph just below the equation like in the snapshot below. To add r-squared value to the graph, select the Show R-squared value on graph check box. This equation includes a slope and an intercept value. Select the Show equation on graph check box to add the equation to the graph. The linear regression trendline highlights that the August value will likely be just above 3500, as shown below.Įach linear regression trendline has its own equation and square value that you can add to the graph. Then you can click Trendline Options and enter “3” in the Transfer text box. For example, suppose you need to forecast a data value three months after May for August, which is not included in our table. Once you have formatted the trendline, you can also forecast future values with it.

The linear regression trendline in the graph above highlights that there is a general upward relationship between the x and y variables despite some declines on the graph. Select Linear and click Close to add this trendline to the chart as shown below. You can select Exponential, Linear, Logarithmic, Moving Average, Power, and Polynomial regression type options from there. This is how you can add linear regression to Excel charts.įirst, click on Trendline Options and select a regression type from there.

For example, if you set up an Excel worksheet table with a month x column and save a data set for each of the months in the adjacent y column, the linear regression highlights the trend between the x and y variables by appending from trendlines to chart charts. In other words, they highlight a trend between two table columns on a worksheet.
