A graph or chart or diagram is a diagrammatical illustration of a set of data. If the graph is uploaded as an image file, it can be placed within articles just like any other image.

Graphs must be accurate and convey information efficiently. They should be viewable at different computer screen resolutions. Ideally, graphs will also be aesthetically pleasing.

Please note that "graph", "chart" and "diagram" are ambiguous terms, sometimes used interchangeably.

Accuracy

Main page: Wikipedia:Don't draw misleading graphs

Graphs that show a trend of data should illustrate the trend accurately in its context, rather than illustrating the trend in an exaggerated or sensationalized way. In short, don't draw misleading graphs.

Choose a type of graph that is appropriate for the data you are illustrating.

• Cartesian coordinates
• Pie chart — good for showing how a whole is divided up (e.g., how much money is spent on each thing in a budget)
• Bar graph — good for showing how things compare to each other (e.g., whether foo or bar is bigger) or how it has changed (e.g., sales of foo each year)

Vega

A graph-making tool called Vega was introduced in May 2015. You can use it to make charts and maps. If you have an old browser, you will see images instead. You can learn how to use it and write help pages for your wiki. You can use the Vega v2 edit tool to make charts and copy the code to your wiki. Note that only Vega 2 is supported at the moment. Charts and maps use complex code, and you should put them into templates.

Methods using Wikipedia templates

Timeline

Main page: Wikipedia:Timeline

A variety of templates and styles are available to create timelines.

• The {{Graphical timeline}} template allows representations of extensive timelines. The template offers complex formatting and labeling options to control the output. Typically, each use is made into its own template, and the template is then transcluded into the article. See an example here, and an example of it being used in an article here.
• The use of fixed images, such as File:Narnia Timeline.svg, was common in the past. However, these are difficult or impossible to adjust later, so this approach is frequently not the best option.
• In other cases, whole articles or sections present timelines in text as association (definition) lists. Timeline of chemistry is a featured list that uses this style to good effect.

Single statistic

70 / 100

{{Composition bar}} can be used to provide a single statistic.

This example shows 70% (70 out of 100), but the template is flexible and can show any positive integer out of any (equal or larger) integer. The template is 100 pixels wide, so the results are rounded to 1%.

To use this, copy the above and replace the values ("70" and "100" in the middle line) and the caption ("70% of women...") with your data. The color can also be changed, from "red" in this example to "blue", "green", or any hex color.

If you want to present multiple statistics, you can stack multiple copies of the template inside the first cell of the table.

Pie chart

1. One (40%)
2. Two (32%)
3. Three (12%)
4. Four (9%)
5. Other (7.00%)

{{Pie chart}} is an experimental graph-drawing template that produces a pie chart 200 pixels wide in the article. When making a pie chart, ensure that the segments are ordered by size (largest to smallest) and in a clockwise direction from 12 o'clock.

Setting the other parameter to yes will pad the chart so that the values total to 100.

This example was created by typing the following code:

{{Pie chart
|other = yes
|value1 = 40
|label1 = One
|value2 = 32
|label2 = Two
|value3 = 12
|label3 = Three
|value4 = 9
|label4 = Four}}

Up to 30 slices can be included.

Horizontal bar graph

Bar chart

{{Bar chart}} is a template that displays the data as a horizontal bar chart. The width of the graph can be changed.

Women's life expectancy at birth

Country	Predicted median age at death
China	71
India	60
USA	79
Indonesia	71
Brazil	67

Bar box

{{Bar box}} is a template that displays the data as a horizontal bar chart. The width of the chart can be changed, but care must be taken to make sure the bars stay within the box on many browsers.

kinds of stuff pcs. Foobar ? 33,213 Barfoo ? 123,123 Bazbar ? 210,121 Barfoobaz ? 12,854 Some stuff displayed by quantity.

Stacked bar

{{Stacked bar}} is a template that displays a set of data as a single bar of a stacked bar chart. The template supports up to 12 segments in their proportional lengths compared to a total, along with captions for each section. Care must be taken that the captions do not overlap excessively in smaller resolutions, and in many cases you may not be able to include captions if the segment(s) is too small.

Vertical bar graph

  Cardiovascular diseases - 29 %

  Infectious and parasitic diseases - 23 %

  Cancer - 13 %

  Respiratory disease - 7 %

  Unintentional injuries - 6 %

  Uncertain - 0.2 %

  Other - 21.8 %

{{Brick chart}} is a simple block-oriented chart template. It assumes that everything must add up to total=100 (or specify), and fills in any missing amounts with "other".

You can label (and optionally choose colors for) each item, and the labels can be wikilinks to relevant articles. Now, decimal amounts are supported (tiny amounts will appear as slivers).

Line charts

The template {{Graph:Chart}} implements line charts, such as:

{{Graph:Chart}} can also draw area charts, bar charts, pie charts and scatter plots.

The Graph extension has been disabled permanently as of July 2025. This alternative, known simply as the chart extension, should work:

Geographical maps

The template {{Graph:Map}} allows to draw geographical maps with either discrete colors for qualitative maps, or a gradient of colors for continuous values per country. Here is an example:

Colors

The default colors are created by Module:ChartColors. The basic 20 are:

                                                                               

If a chart plots 10 colors or fewer, then by default it uses every other one:

                                       

The colors can be manually set in a graph by adding them to the 'colors' parameter. For example, for two pie charts, the first of which is default and the second of which omits some colors in the first, you would manually enter your selections from the default 20:

colors=#1f77b4,#aec7e8,#ff7f0e,#ffbb78,#2ca02c,#98df8a,#d62728,#ff9896,#9467bd,#c5b0d5,#8c564b,#c49c94,#e377c2,#f7b6d2,#7f7f7f,#c7c7c7,#bcbd22,#dbdb8d,#17becf,#9edae5

Similarly if one chart plotted fewer than 10 colors and you wanted it to use the same colors as another that had more than 10.
