Charts in a document

A chart earns its place when the shape of the data is the point. Six types are available, they take the document theme colours, and the honest advice is that most documents need fewer charts than they contain.

The six types and what each is for

Bar compares categories. Horizontal bar does the same when the labels are long, which is most of the time in a business document. Line shows a value over time. Area does the same when the volume underneath matters. Pie and donut show parts of a whole, and they only work with a handful of slices, so if you have nine categories use a bar chart instead.

One message per chart

A chart that shows three things shows nothing. Decide the single sentence the chart is making, then check that the chart makes it without the caption. If it needs the caption to be understood, the caption is the content and the chart is decoration.

They take the theme

Charts are drawn in the document theme colours rather than a fixed palette, so switching the theme restyles them with everything else and a document does not end up with one section in somebody else’s brand colours.

When a table beats a chart

When the reader needs the actual numbers, which in an invoice, a budget or a rate card is always. A chart is for shape and a table is for values. Reports that carry both usually want the chart for the trend and the table for the detail, in that order.

Label it so it survives being photocopied

A chart in a document is read on paper as often as on screen, and often in black and white. That rules out colour as the only way to tell two series apart, and it rules out a legend far from the data. Label the series on the chart where you can, put the units in the axis title rather than assuming them, and check the chart still makes its point when the colour is gone.

How it works, in three steps

  1. Step 1

    Write the sentence first

    Say what the chart proves. If you cannot, you want a table.

  2. Step 2

    Pick the type from the data

    Categories to bars, time to a line, parts of a whole to a pie only when there are few slices.

  3. Step 3

    Caption it with the finding

    A caption that repeats the axis labels is wasted. Say what the reader should take away.

Questions people ask

What chart types are available?

Six: bar, horizontal bar, line, area, pie and donut.

Can a chart pull live data?

No. It draws the values in the document, so it is a snapshot rather than a dashboard.

Should I use a pie chart?

Only with a few slices where the parts genuinely make a whole. Past about five categories a bar chart is easier to read.
