Line Plot Maker
A free line plot maker for anything that moves over time. Enter the periods and the values, and this line graph maker draws the trend, the grid and the hover readout in your browser — then hands you an SVG or PNG.

How to make a line plot
- Put the time periods in the left column, in order. Evenly spaced periods — days, weeks, months, quarters — keep the slope honest.
- Put one measure per series column. Add a second series to compare two things on the same axis, as long as they share a unit.
- Use Area instead of Line when the quantity accumulates towards a total and the filled shape carries meaning.
- Add a unit so a reader knows whether 63,400 is dollars, sessions or seconds.
- Download SVG or PNG, or copy the CSV back out.
Line plot, line graph, line chart — are they different?
In everyday use, no. A line plot, a line graph and a line chart all mean the same picture: points joined in order along an axis. In some school curricula "line plot" also names a dot plot — a number line with an × stacked for each observation — which is a frequency chart, not a trend. This page makes the trend kind; for the counting kind a bar chart of the counts is clearer anyway.
Reading a line plot honestly
- The slope is the message. If two series share an axis they must share a unit, otherwise the crossing point means nothing.
- A non-zero baseline is legitimate here, unlike with bars — but label the axis clearly, because a zoomed axis makes small noise look like a crisis.
- Do not join points across a gap in the data. A straight line over a missing month is a claim you did not measure.
- Mark what changed. A price change, a launch or an outage explains more than any amount of smoothing.
When to use something else
- Few categories that are not a sequence — use a bar graph; connecting unordered categories implies a trend that does not exist.
- Parts of a whole at one moment — use a pie chart or a stacked bar.
- One headline number — use a stat tile. A two-point line is not a trend.
Frequently asked questions
Can I plot two lines on one chart?
Yes. Use "Add series" for a second column of values. Keep both in the same unit so the shared axis stays meaningful.
What if some periods have no data?
Delete those rows rather than entering zero. A zero is a measured value; a gap is not, and drawing through it misleads the reader.
Can I switch to an area chart?
Yes, with the chart-type buttons above the chart. Area suits cumulative quantities; plain lines suit rates and ratios.
Is the data sent to a server?
No. The line plot is rendered client-side and the numbers stay in your browser.
