Free Line Graph Maker

Each row becomes a category at an equally spaced horizontal position, in the order supplied. Week 1, Week 2 and Week 4 would still be equally spaced; the longer time gap would not be represented. Arrange a complete regular sequence before building. Do not hide a missing period by relabeling the remaining rows as consecutive observations.

A line helps a reader follow an ordered sequence. It is less suitable for unrelated categories such as departments or product names; bar graph maker is an alternative for comparing those amounts. For numeric x positions with unequal distances, consider scatter chart maker. Choose a tool that supports the values and spacing your data requires.

This is synthetic data, not a study or customer activity. Open Paste data and copy the following five comma-separated lines, including the header:

Week,Trial A,Trial B

Week 1,10,12

Week 2,15,14

Week 3,12,18

Week 4,20,20

Confirm that the first row is treated as a header, then choose Build graph. Replace the title with Illustrative weekly observations, the subtitle with Synthetic example — two trials, four weekly readings, the vertical axis with Observed units, and the horizontal axis with Week. Keep the line names Trial A and Trial B.

Choose Studio, Report (960 × 620), Legend Top, straight lines, Point markers and Grid lines. Turn Show values on to check the eight numbers. Trial A changes from 10 to 15 to 12 to 20; Trial B changes from 12 to 14 to 18 to 20. Both finish at 20, but only Trial A falls between Weeks 2 and 3. This describes the supplied values, not an explanation for the change.

The nearby Week 2 values and coincident Week 4 values can crowd each other. Turn Show values off for this final image, retain the legend and markers, and keep this source table with it. Download PNG and check the title, units, four week labels and both lines. A smooth curve or decorative motion is not evidence of unmeasured values between the weekly observations.

Use a complete table with one value per line at each position. Plain nonnegative numbers and decimals avoid ambiguity. The paste panel identifies a row and column to correct when a value is missing or invalid; it does not replace the chart until the paste is valid. Review the first-row header choice when names and numbers could be mistaken for data.

On the chart, select a point to edit its Value field, turn on Show values to edit a label, or drag the point vertically. A rejected manual draft leaves the plotted number unchanged. Blur, Enter and Escape restore the latest accepted number; they do not undo valid edits made earlier. Focusing an abbreviated label exposes its exact stored value.

A zero means an observed value of zero. Do not fill unknown measurements with zero merely to pass validation. This studio cannot leave a gap inside a line; use a suitable alternative if missing observations or negative values are essential to the chart.

Six themes and three canvas sizes change presentation, not the meaning of the data. Keep units consistent between lines, replace every unrelated starter label, and choose a legend position that identifies the series. Straight segments and markers make the example observations easy to locate; smoothing is an optional visual treatment.

The canvas zoom control changes the on-screen view, not the standard PNG dimensions. Inspect the downloaded Compact, Report or Slide image for readable axes and line names. Long sequences may omit some labels, and nearby or coincident value labels can overlap. Hide Show values and supply a table when exact amounts need more room.

Standard PNG needs no account. HD PNG, SVG and MP4 use Pro access or an active export pass; saving an editable design requires sign-in. Check the format and access requirement before choosing it. A PNG is suitable for placing in a document or slide, but does not retain the studio controls for later editing.
