Line Chart Maker

How to use the Line Chart Maker

  1. Open the Line Chart Maker and review the sample Month / Revenue / Profit CSV.
  2. Paste your own CSV or TSV from Excel — first column is the X axis, remaining columns become series.
  3. Watch the chart animate as you edit values in real time.
  4. Switch Fintech, Terminal, or Print themes, then download a high-res PNG.

Why chart locally?

Financial and operational datasets often contain sensitive figures. This chart maker parses and renders entirely in your browser with zero server uploads.

Frequently asked questions

What CSV format is required?

Include a header row. The first column is treated as categories (e.g. months). Each additional column becomes a line series.

Is my data uploaded?

No. PapaParse and Apache ECharts run 100% client-side. Your spreadsheet never leaves the device.

Can I export the chart?

Yes. Use Download High-Res PNG to save a 2× pixel-ratio image for decks and reports.

Is this Line Chart Maker free?

Yes. Every tool on charts.logicapplabs.com is free with no account required.
