Paste a time series, get a trend line you can edit in PowerPoint or WPS — native chart object, missing months drawn as honest gaps, not fake zeros. Free, no sign-up.

Give ChartThat a table with a period column — months, quarters, years — and one or more numeric columns. When the shape says "something is moving", the line chart shows up among the recommendations. Export it as a native, editable PPTX chart (double-click to open the data sheet in PowerPoint or WPS) or as an animated GIF for the deck that needs motion. Free, no sign-up, no watermark.
When a line chart wins
- The story is momentum. Growth, decline, recovery, plateau — slopes read instantly, bar tops do not.
- You need the inflection point. The month churn flattened, the quarter growth bent. Lines make turning points visible; that is where you put your talk track.
- Two or three series race. Plan vs actual, this year vs last. A few lines on one axis is the cleanest race in the chart world.
When it lets you down
- Your categories have no order. A line across "North, South, East, West" implies a journey that does not exist. Use a bar chart.
- More than four series. Spaghetti. Cut series or split the chart — attention is the budget.
- Composition is the point. If the parts matter more than the movement, that is an area or stacked bar job.

Field notes on lines
- A missing month is a gap, not a zero. ChartThat draws absent values as an honest break in the line. A fake zero turns "we don't know" into "we crashed" — and someone will ask about the crash.
- Mark the moment you changed something. The pricing change, the launch. An annotation beats a footnote nobody reads.
- Thin line, calm color, loud endpoint. The eye travels the slope and lands on the latest number — make that the one it remembers.
- Truncating the y-axis is legal here. Unlike bars, lines encode position, not length — but say the range out loud when you present, or the room will assume zero.

From the field notes
Urgency wants a line — the reasoning is in field note #1. And before you fill a missing month with zero, read why that number is a lie.
