A dynamic range chart in Excel allows the data in the chart to update automatically when the underlying data changes. This is useful when you have a large dataset that is constantly being updated and you want the chart to reflect these changes without having to manually update the chart.
The table
It is very easy for you to add dynamic range to a chart. We are going to go through this, in a step-by-step format.
Click on insert (1) and then choose table (2).
Just click ok.
Note: If you click on the beginning of data, it would automatically choose all the range. If it does not, you can change it yourself. Otherwise, just follow the step.
A scatter chart
Click on insert (1), and then click on scatter chart (2).
Add data to the table created in step 2, and the chart would be dynamically changing.
Your chart will now dynamically update whenever the underlying data changes. This can save you a lot of time and effort and make your data analysis more efficient.
