A small dataset to try

Week,Open tickets
1,18
2,30
3,25
4,12

Open tickets peak at 30 in week 2 and decline to 12 by week 4. The chart shows the measured backlog at each point; adding the four values would not necessarily count distinct tickets.

When to choose this chart

An area chart emphasizes a nonnegative quantity changing over an ordered axis. The fill draws attention to the size of the series, making a clear baseline important.

Prepare and map your fields

Choose an ordered label, numeric or ISO-date X field and nonnegative numeric values. Review sorting and aggregation before filling the area under the line.

Map a single measure first so the filled shape has an unambiguous meaning.

Check the zero baseline and the interval represented by each point.

For multiple overlapping areas, review whether one fill hides another; a line chart may be clearer.

Read the result correctly

Read the vertical value at a position on X. The shaded shape is a visual emphasis, not an automatically calculated cumulative total or integral.

A mistake to avoid

An area chart can imply additive volume even when observations are snapshots. Negative values are unsuitable for this tool's area view, and overlapping fills can hide smaller series.

Export and keep your data private

Review the title, units, labels and any omitted-row warnings at the final export size. PNG is a raster image, SVG retains vector chart elements, and PDF embeds a raster image. Save the original table if you may need to revise the mapping.

Data stays in browser memory; no upload, external chart service or AI model. CSV, TSV, semicolon/pipe text, JSON and JSON Lines: 2 MB, 10,000 rows, 24 columns. Charts allow up to eight series; categorical charts 60 groups, lines/scatter/candlesticks 500 rows, pie/donut/waffle 12 categories, radar 3–12 dimensions. Blank/invalid mapped values are omitted and counted. Numeric values use a decimal point; remove currency symbols and grouping separators. Percent strings are treated as displayed numeric values (25% becomes 25). Dates use ISO format. Recommendations check data structure, not meaning or causation. PNG up to 16 MP; SVG stays vector; PDF embeds a high-resolution chart image. Review mappings, ordering, aggregation and labels before sharing.
