# Pulling figures from a graph

I was wondering if there's any possible way of pulling data for a trendline from a graph and show it in a cell. The two values I'm trying to get are the slope of the line and the R squared value as seen below as y = 2.164ln(x) + 15 and R squared = 1. currently what I have to do is enter the data and the graph is created, then I have to manually type the data

Hi @LiamHiggins,

To extract the slope and R-squared value from a trendline in Excel, you can utilize Excel's built-in features. Follow these steps:

1. Display the equation on the chart: Right-click on the trendline, select "Format Trendline" from the menu, and then enable the "Display Equation on chart" and "Display R-squared value on chart" options.

2. Utilize the TREND function: Excel's TREND function allows you to calculate y-values based on a trendline for given x-values. This function employs linear regression to determine the result. The syntax is =TREND(known_y’s, known_x’s, new_x’s, const), where known_y’s and known_x’s represent the known x and y data in your data table, new_x’s is an array of data points for which you want to predict the y-value, and const is a binary argument for calculating the y-intercept.

Note that the TREND function acts as a dynamic array formula, automatically spilling the result for the entire array.
