Types of line chart
Line charts are essential for showcasing trends over time. In Power BI, they’re perfect for illustrating fluctuations in sales, web traffic, stock performance, and any metric that evolves chronologically. A line chart connects individual data points with continuous lines, helping users understand patterns at a glance.
“A line chart doesn’t just show where you are — it reveals where you’ve been and where you’re going.”
🛠️ Getting Started with Line Charts
- Step 1: Drag a line chart visual onto your report canvas from the Visualizations pane.
- Step 2: Set the X-axis to a time-based field such as "Date," "Month," or "Quarter."
- Step 3: Assign a metric (e.g., Sales, Visitors, Profit) to the Y-axis.
- Step 4: Add a Legend if you're comparing multiple series, like different product lines or regions.
🎨 Customization Options
Power BI allows you to tailor line charts using the Format pane. You can:
- Change line color and thickness for each series.
- Add markers to emphasize specific data points.
- Enable Data Labels to show values directly on the chart.
- Insert Trend Lines to highlight general movement over time.
- Use Tooltips to provide context when users hover over points.
💡 Pro Tip: Use a combo chart to overlay a line chart on a bar chart when comparing volume (bars) with trends (lines) — perfect for revenue vs. growth rate visuals.
📊 Types of Line Charts in Power BI
- Basic Line Chart: A single metric over time — ideal for straightforward trends.
- Multi-Line Chart: Compare multiple series like different product categories or countries.
- Line and Stacked Column Combo: Combines bar and line to show dual metrics with contrasting display styles.
- Area Chart (Line Variant): Adds shaded color below the line to emphasize volume and magnitude.
Whether you're tracking KPIs or forecasting performance, line charts offer clarity and continuity. With proper formatting and interactivity, they transform raw data into compelling visual stories that decision-makers can act on instantly.

📉 Single Series Line Chart
A Single Series Line Chart in Power BI is one of the most effective ways to highlight the progression of a single metric across time. Whether you’re visualizing monthly revenue, website visits, or temperature changes, this chart type offers a clear, continuous view of change over time.
It consists of a single data line plotted across the X-axis (usually time) and the Y-axis (the metric). This makes it ideal for identifying trends, seasonality, or sudden spikes and dips in performance.
“A single line can tell a complete story — if the axis and context are right.”
🔧 How to Create in Power BI
- Drag the Line Chart visual onto the canvas.
- Assign a Time-based field to the X-axis (e.g., Month, Date).
- Place the metric (e.g., Sales, Cost, Score) on the Y-axis.
- Style the line using the Format pane for color, thickness, and markers.
💡 Pro Tip: Keep the line smooth and label key milestones using Data Labels or Annotations. This improves interpretability without overwhelming the chart.
When your story involves just one metric over time, a Single Series Line Chart is your go-to visual — clean, precise, and insightful.

📈 Multiple Series Line Chart
A Multiple Series Line Chart in Power BI allows you to visualize and compare multiple metrics or categories on a single timeline. Each series is represented by its own line, providing an easy way to spot patterns, correlations, or divergences between variables over time.
This chart type is ideal when your analysis involves comparing more than one entity — like tracking revenue, cost, and profit across months, or analyzing multiple product lines simultaneously.
“A well-constructed multi-line chart lets you see the story between the lines — not just on them.”
🔧 How to Create in Power BI
- Add a Line Chart visual to your report canvas.
- Assign a date or time field to the X-axis.
- Place a measure (e.g., Sales) on the Y-axis.
- Add a Legend field (e.g., Product Name, Region) to display separate lines for each value.
✅ Best Practice: Use contrasting colors for each line and include a clear, readable legend. Avoid using too many series — stick to 3–5 to keep the chart legible and visually balanced.
Multiple Series Line Charts are excellent for comparative analysis and performance benchmarking. Just make sure your story stays readable — clarity always beats clutter.
-
📊 Stacked Line Chart
A Stacked Line Chart in Power BI is designed to display the cumulative contribution of multiple data series over time. Rather than overlapping lines, each series is stacked on top of the previous one, giving a visual sense of both total growth and individual contributions.
This format is especially helpful for understanding how different segments contribute to a whole — for example, tracking department-wise budget usage, or customer acquisition from various channels.
“Stacked line charts help tell the story of accumulation — who contributes most, and when.”
🛠️ How to Build in Power BI
- Insert a Stacked Area or Line Chart visual from the Visualizations pane.
- Drag a date field into the X-axis.
- Add your measure (e.g., Revenue, Users) to the Y-axis.
- Add a category field to the Legend to split the stacked values by group.
💡 Pro Tip: Use tooltips to break down each layer’s value at specific time points. This makes the cumulative data more transparent and easier to interpret.
Stacked Line Charts are great for showing overall growth while maintaining visibility into segment-level changes — just remember they may not be ideal for comparing series individually.
-
📈 100% Stacked Line Chart
The 100% Stacked Line Chart is a variation of the standard stacked chart, designed to show the relative percentage that each series contributes at every point along the x-axis. Each stacked point totals exactly 100%, making it perfect for understanding proportional trends over time.
This chart is particularly helpful when you want to compare distribution or share across different segments — for example, the percentage contribution of marketing channels to total traffic each month.
“Use 100% stacked visuals when the focus is on ratio or proportion — not raw values.”
🛠️ How to Build It in Power BI
- Select the 100% Stacked Area or Line Chart visual from the Visualizations pane.
- Add a date or time-based field to the X-axis.
- Add your measure (e.g., count of users, sales) to the Values section.
- Use a category or group field in the Legend to split data into multiple lines.
✅ Best Practice: 100% stacked charts work best when the number of categories is small and color distinctions are clear. Use tooltips or filters to help viewers explore detailed percentages.
In summary, 100% Stacked Line Charts give a quick view of how the composition of data shifts over time, even when the total values themselves are not the focus.
-
📊 Area Chart
The Area Chart is a close cousin of the line chart, designed not just to show trends over time but also to emphasize the magnitude of change by filling the space below the line with color. This makes it ideal for highlighting cumulative values or visually reinforcing volume and dominance among data series.
Area charts can be single-series or stacked (even 100% stacked), and are frequently used to represent things like total revenue growth, cumulative signups, or share of voice in marketing over time.
“Think of area charts when you want to combine trend with quantity — especially when comparing totals visually.”
🛠️ How to Build It in Power BI
- Select the Area Chart visual from the Power BI Visualizations pane.
- Add your time-based field (e.g., date or month) to the X-axis.
- Drag your measure (like revenue or sessions) to the Values area.
- For multi-series, use a Legend category to break it by product, channel, etc.
💡 Tip: Area charts look great with smooth lines and partial transparency. Avoid overlapping too many categories — keep it to 3–4 series for optimal clarity.
Use area charts to make trends visually rich and easy to compare at a glance — especially when total value over time is just as important as the pattern itself.
