How to Make a Line Chart in Excel: Step-by-Step Setup
Learn how to make a line chart in Excel: prepare data, insert the chart, fix axes, and format for readable KPI reviews.
A how to make a line chart in excel search usually means someone has numbers in a sheet and five minutes before a stand-up. The steps are short — select data, Insert, Line — but the chart still fails when the table has blank rows, a total at the bottom, or dates stored as text. This guide walks through a reliable sequence: shape the grid, insert a 2-D line chart, fix axes and legend, then sanity-check before you paste into slides.
If you are still choosing among download paths and target-line layouts, start with the hub Download Google Spreadsheet Line Chart Template: Choose and Use. For data layout rules before charting, see How to Make Line Chart Data in Excel. More guides live in our template guides and tips.
Key takeaway: Make the table correct first — dates down, values across, no totals in the selection — then Insert → 2-D Line. Most “broken” charts are data-range problems, not missing design talent.
Before Insert: a table Excel can chart
Line charts expect a matrix: categories (usually dates) in the first column, one or more numeric series in the columns beside it. Microsoft Support and Excel Easy show the same shape.
Minimum viable layout:
| Date | Metric |
|---|---|
| 2026-01-01 | 120 |
| 2026-01-08 | 135 |
Turn the block into an Excel Table (Ctrl+T) if you will append rows weekly — the chart can expand with the table. Keep text out of value columns; use a separate notes column outside the chart range if needed.
Warning: Do not include a Total row in the selected range. Excel plots totals as another point and distorts the scale.
Insert a line chart in five steps
Insert a 2-D line chart
- Select the date column and value column(s) including headers.
- Go to Insert → Insert Line or Area Chart → Line (2-D).
- If series group by the wrong dimension, open Chart Design → Switch Row/Column.
- Click the chart → Chart Design → Add Chart Element to add axis titles and tune the legend.
- Right-click the horizontal axis → Format Axis → set Axis Type to Date axis when values are real dates.
DataCamp’s Excel chart tutorials echo the same sequence for beginners. Alt+F1 creates a default chart from the selection — change the type to Line if Excel guessed column.
Format for readability, not decoration
After the chart exists, spend five minutes on clarity:
- Title — state the decision (“Weekly sign-ups vs 200 target”), not “Chart1”.
- Lines — 2–4 series max before clutter; see Multiple Line Chart Excel when you need more.
- Markers — show markers on sparse data; hide on dense daily series.
- Gridlines — light horizontal lines only; delete vertical grid noise.
- Colors — pick distinct hues; avoid red/green-only pairs for accessibility.
[TABLE: Quick fixes]
| Symptom | Likely cause | Fix |
|---|---|---|
| Flat line at bottom | Text dates | Convert column A to dates |
| One giant spike | Total row selected | Shrink data range |
| Single dot | One data point | Add more periods or check filters |
| Legend shows “Series1” | Header missing | Include header row in selection |
Product highlight: Switching the horizontal axis to Date axis after import prevents Excel from treating ISO dates as category labels with uneven spacing.
Add a second series without starting over
You do not need to rebuild the chart to compare two metrics.
- Type the new series header in the next column and fill values.
- Click the chart → blue range handles appear on the sheet.
- Drag the corner to include the new column, or use Select Data → Add → pick the new range.
If scales differ wildly (units vs percentage), consider two charts or a combo approach — not two unrelated metrics forced onto one axis without thought.
Target lines and templates
When the stand-up question is “are we on plan?”, a horizontal goal line helps. Native options include a constant helper column plotted as a line — detailed in Add Target Line to Excel Chart.
If your team repeats the same chart every sprint, a structured workbook saves setup time. The PlanoNest line chart template ships with time-series examples and target-line patterns as a one-time purchase with instant download — see the product page for pricing. Pair it with this how-to when you customize colors after pasting live data.

Checklist before you paste into PowerPoint
- Data range excludes totals and blank separator rows.
- Horizontal axis uses Date axis when appropriate.
- Legend order matches the story you will tell aloud.
- Value axis title includes units (% , $ , count).
- Source table sits on the same sheet or a clearly named tab.
When the checklist passes, the line chart does its job: show trend over time without making the audience decode spreadsheet errors.
Update the chart when new weeks arrive
Teams that chart weekly KPIs should not recreate the chart every Monday. Tie the chart to an Excel Table so new rows at the bottom extend the blue data range automatically. Paste values only — avoid inserting rows above the header, which breaks structured references. If you must append manually, drag the chart’s range handles once, then save the workbook as the team standard.
When someone emails a CSV export, paste into a staging tab first. Compare column headers to your chart tab before overwriting live data. A two-minute header check prevents the legend from silently swapping series.
Copy to slides without breaking the story
Paste as Picture when the deck is final and numbers will not change before the meeting. Paste as Linked Picture or embed the workbook when finance may refresh figures during the meeting — but test links on the conference room laptop first. Crop empty plot margins in Excel before paste so the slide title aligns with the chart title.
Frequently Asked Questions
How do I make a simple line chart in Excel?
Dates in column A, values in column B, select both with headers, Insert → 2-D Line.
Why does my line chart look wrong?
Wrong range, totals included, text dates, or swapped rows/columns — fix the table first, then Switch Row/Column if needed.
Can I add a second series later?
Yes — extend the chart’s data range or use Select Data → Add.
Should the value axis start at zero?
Start at zero when absolute magnitude matters; narrow axes are OK for bounded rates if the audience knows the scale.
Where do target lines fit?
Add a constant helper series or follow the dedicated target-line guide in this cluster.
