Use cases

When to use a line graph

Best uses

  • Show how a metric rises or falls across days, months, or years
  • Highlight the rate of change through the slope of the line
  • Track a single continuous series measured at regular intervals
  • Reveal seasonal or cyclical patterns over a long range

When another chart fits better

  • Unordered categories belong in a bar chart instead
  • Part-to-whole stories suit a pie or stacked bar chart
  • Several groups read better as a grouped line chart

FAQ

Line Graph maker FAQ

Answers to common questions about making a line graph with InstaCharts.

Is the line graph maker free?

Yes. You can create and export a line graph for free with no account. The free tier supports up to 500 rows and adds a small watermark; paid plans from $10 user/mo remove it.

What data do I need to make a line graph?

A column of dates or an ordered sequence for the X-axis and a numeric column for the values. Paste it in, upload a CSV or Excel file, or connect a Google Sheet.

Can I plot more than one line?

Yes. Add a breakdown column to turn the chart into a grouped (multi-line) chart, with one colored line per category, so you can compare trends side by side.

Does my line graph update when my data changes?

If you connect it to Google Sheets, yes. The chart, including any embed on your website, stays in live sync and refreshes automatically when the sheet changes.
