What is a Line Chart?
A line chart plots data points connected by straight or curved lines, making it the go-to chart for showing how values change over time. It excels at revealing trends, patterns, and momentum — whether you're tracking monthly revenue, website traffic, or temperature readings. Use a line chart whenever the sequence and direction of change matters as much as the values themselves.
Key Features
Flexible Line Styles
Switch between solid, dashed, dotted, or dash-dot patterns to differentiate multiple series at a glance.
Configurable Data Points
Show or hide dots at each data point to control chart density and highlight key values.
Adjustable Stroke Width
Control line thickness to balance readability and visual weight for any audience or display size.
Legend Placement
Position the legend at the top, bottom, left, or right to keep the chart clean and easy to read.

Best For
Monthly or quarterly revenue tracking
Website traffic and engagement trends
Stock price or financial performance over time
Temperature, weather, or environmental data
Product usage or retention curves
Project progress and milestone tracking
When to Use
- Your data has a meaningful time or sequential order
- You want to highlight the rate of change, not just individual values
- You're comparing how two or more series trend relative to each other
- The relationship between consecutive data points matters
- You need to spot peaks, dips, or inflection points quickly
- Your dataset has more than 5–6 data points (use a bar chart for fewer)
Common Mistakes
- Plotting too many lines on one chart — more than 5 series creates visual clutter
- Using a line chart for categorical data with no natural order (use a bar chart instead)
- Starting the Y-axis at a non-zero value, which exaggerates small changes
- Connecting data points that have gaps or missing values without indicating the break
- Choosing smooth curves for data that doesn't actually interpolate between points
- Omitting axis labels or units, leaving viewers to guess what the values represent
