Dynamic Charts with Formulas

A dynamic chart range is a data range that changes automatically based on a condition or selection. Instead of building a chart from a fixed range, you build it from a formula-driven range. When the formula result changes, the chart updates. The chart itself is not dynamic. The data source is.

How It Works

1. A user selects a value from a dropdown;
2. A formula returns only the matching rows;
3. The chart is built from that formula output;
4. When the selection changes, the formula output changes;
5. The chart updates automatically.

The key idea: the chart depends on a formula range, not the full dataset.

Creating the Dynamic Range

Assume:

Step 1: Create a Dropdown

1. Select an empty cell;
2. Go to Data → Data Validation;
3. Choose List;
4. Select the category range.

Step 2: Create the Formula Output

In a new area, enter: =FILTER(A2:C100; B2:B100=E2)

This creates a dynamic output table.

Step 3: Build the Chart

Insert a chart using the filtered output, not the original data. Now the chart updates when the dropdown changes.

Task

Using the provided dataset:

• Create a dropdown cell to select a Category;
• Use the FILTER function to return matching rows into a separate output area;
• Insert a Line or Column Chart based on the filtered output range;
• Change the dropdown selection and confirm that the chart updates automatically.

Goal: build a chart that updates based on a formula-driven data range, not manual filtering.
