Line Charts

A line chart connects data points in a continuous line – perfect for showing chronological trends.

I know the example above isn't Power BI, it's Google Trends, but let me have my fun.

What Are Line Charts Good For?

Showing trends and patterns over time
Comparing multiple time-based series
Highlighting increases, decreases, or steady trends

Line charts are perfect when you have a time-based X-axis (like date, date_month, or date_week) and a numeric Y-axis (like sale_quantity or product_list_price).

Assignment

While still on the Sessions page, click an empty area of the canvas, then click the "Line chart" icon in the Visualizations pane. This should add a line chart below our column chart. Have it take up the bottom half of the page.
Drag session_date to the X-axis.
Drag session_pages_visited to the Y-axis.
You'll likely see all the data on a single point, which is not ideal! Click on the dropdown next to session_date in the X-axis selection. Change it from "Date Hierarchy" to session_date. This should expand the data to show day-by-day.
Title the chart Pages Visited by Date.

Save the project and, from the course directory, submit the CLI tests.
