How to show an Intersection point in a Microsoft Excel graph

In Excel, showing the intersection point on a graph refers to displaying the coordinates where two or more plotted lines or curves intersect. This feature is particularly useful when analyzing data and identifying the exact point of intersection between different variables or trends. 

In this tutorial, we will learn how to show an Intersection point in a Microsoft Excel graph. In Microsoft Excel, we can simply identify the intersection point by utilizing the scatter chart with a smooth line. 

Currently, we have a line chart, and our objective is to display the point where the line intersects with another line that has its data points specified within the sheet. 

Step 1 – Select the Range of the cell 

  • First, select the range of the cell of the first dataset 

Step 2 – Go to the Insert  

  • Now go to the Insert tab and select the option Insert Scatter from the Chart group options 

Step 3 – Click on the option Scatter with Smooth line

Step 7 – Select the range of Y values  

  • Now select the range of Y values of The second Data Set 

Step 8 – Perform a Click on Ok 

  • Now perform a click on the Ok of the Dialog Box and then click on the OK of another Dialog Box after that graph of the data set with intersection points will appear. 

Step 9 – Identify the Intersection Point
