Line Graph Maker

It takes a set of values measured over time and draws them as a connected line, so the shape of the change is visible rather than having to be read out of a table. The part that varies between tools is how much tidying you have to do first, and whether anything checks that the picture matches the numbers.

Yes. One chart at a time runs on the free plan. Longer series, keeping one visual style across a whole report, and storing the choices so later charts match are on the paid plans.

Paste it, upload it, or describe it. A spreadsheet export, a CSV, a table copied out of a document, or a handful of figures typed into the box all work — including the ones with subtotals buried in them, merged headers, or dates written four different ways.

When the horizontal axis is not a scale. Regions, product names, survey answers, teams — these have no order that a connecting line could mean anything about, so joining them up invents a relationship. That picture wants Bar Graph Generator instead.

Most are drawing surfaces: give them clean numbers and they render them faithfully, including faithfully rendering a misleading chart. Here the data can arrive messy and the result comes with a note when the chart is arguing with it — and the choices you make about scale and colour stay on file, so a monthly series looks like a series rather than twelve separate attempts.
