In Excel: put time or ordered categories in the first column, values in the next column, select both, then Insert ▸ Line or Area Chart ▸ Line.
Arrange the x-axis labels in the first column and the values in the next column.
Select only the label and value range, excluding totals.
Choose Insert ▸ Line or Area Chart ▸ Line.
Add a chart title, axis labels and markers when the individual points need to be visible.
What this does
A line graph connects values in order, usually across time, so the slope makes direction and change visible. The first column should hold dates, months or ordered categories; the second holds the values to plot. Excel treats each additional numeric column as another line, which is useful for comparing series but messy if totals or helper columns are accidentally selected. Keep the inputs visible and clearly labelled and the whole thing stays auditable — anyone who opens the file later, including you, can see at a glance exactly what feeds the result and change one assumption without hunting through the formula. For “make a line graph in excel”, the reliable version is a short checking loop, not just the first command that appears to work. Run it on a deliberately small range first, watch how the affected chart change, and only then apply the same setup to the full sheet. When this is a ribbon command, the selection matters more than the button: confirm the range, apply the command, then spot-check the output before saving. That is what makes a visual that makes the number obvious at a glance useful in real work: repeatable, auditable, and not dependent on memory or luck.
A worked example
Months Jan through Jun are in A2:A7 and sales 42, 51, 48, 61, 67, 73 are in B2:B7. Select A2:B7, choose Insert ▸ Line Chart, and Excel draws a six-point line rising from 42 to 73. Add markers if individual months matter, and format the vertical axis to start at zero only when that supports the story rather than flattening the change. Line graphs are strong for trends: monthly sales, weekly traffic, running totals, error rates, production output and any metric where readers need to see direction over a sequence. One habit worth forming early: name the cells that hold your inputs, so the formula reads in plain language instead of a string of cell addresses. A reviewer — or you in three months — can then follow the logic without decoding what B7 and D2 were supposed to mean, which is most of what makes a sheet maintainable.
In Google Sheets
Everything above works in Google Sheets too. Excel and Sheets share the formula syntax used here; only the surrounding menus are arranged differently. That portability is deliberate — learn it once and it follows you between the two tools and across Windows and Mac. Keep this page bookmarked for the next time the same question comes up. Better still, rebuild the example once in your own sheet — doing it yourself, with the tool above to check against, is what turns a copied formula into a technique you own. If you take one thing from this page on “make a line graph in excel”, make it the habit rather than the keystrokes: set the problem up with labelled inputs, reference those cells, and let Excel do the recomputing. Bookmark the page for the syntax, but do the example once in a blank sheet and check it against the tool above — five minutes of hands-on practice fixes the method in memory far better than re-reading, and it surfaces the small snags while they are still harmless. After that the technique is genuinely yours: faster than searching for it again, and reliable enough to drop into work that other people depend on.
Common mistakes
- Using a line chart for unordered categories, where a bar chart would compare values more honestly.
- Including a total row, which creates a sudden fake spike at the end.
- Letting Excel treat text dates as categories; convert them to real dates when spacing matters.
- Plotting too many series at once, turning the chart into unreadable crossing lines.
Frequently asked questions
When should I use a line graph?
Use it for ordered data, especially time series, where the change from one point to the next matters.
How do I add a second line?
Place the second value series in another column beside the first, include it in the selected range, and Excel plots it as a separate line.
Line chart or scatter plot?
Use a line chart for ordered categories or dates; use a scatter plot when both axes are numeric measurements.
