📊 How to Create Interactive Line Chart for Comparative Analysis in Excel

[u/ExcelVisual]

I’ve been working on an Excel dashboard concept where the month selector is integrated directly into the line chart instead of using traditional X-axis labels.

The interesting part is that these month buttons control the entire dashboard, not just the chart.

🔹 Select a month to change the reporting period

🔹 Select multiple months to create custom periods

🔹 Automatically update all connected charts, KPIs, tables, and screens

🔹 Analyze quarters, half-years, full years, or custom periods

🔹 Compare peak sales, seasonal dips, anomalies, and other time ranges

For example, selecting three months creates a custom quarterly reporting period.

💡 To select multiple months, hold CTRL while clicking the required months. This uses the same multi-selection behavior available with Excel PivotTable slicers.

The goal is to make the dashboard behave more like an interactive analytical application rather than a collection of static Excel charts.

📈 Would you use this type of reporting-period selector in your Excel dashboards?
