Answer: how to add data points to a scatter plot with trend line
Steps to add data points to a scatter plot with a trend line in Microsoft Excel:
- Create your scatter plot with the existing data points. To do this, select the data you want to plot, including the x-axis and y-axis values. Then, go to the "Insert" tab and select "Scatter" from the chart options.
- Add a trend line by right-clicking on any data point and selecting "Add Trendline" from the drop-down menu.
- In the "Format Trendline" pane that appears on the right side of the screen, select the "Options" tab. Under "Forecast," you can choose how far into the future you want the trend line to extend.
- Add your new data points to the scatter plot by entering them into the worksheet as additional rows of data. Make sure to include both the x-axis and y-axis values for each point.
- Once you have entered your new data points, they should automatically appear on the scatter plot. If they don't, you may need to adjust the axis scales to make sure they are visible.
