Chart titles and captions make visualizations far easier to comprehend. Use titles whenever possible. Titles can combine both a main title and a subtitle to provide additional information about the chart.

NEED CONTENT

Use simple language, free of acronyms to clearly explain what the subject of the chart is. Keep the title short and precise and avoid using articles like a, an, the as well as adjectives like great, amazing etc

<C100 insert image – chart long weird title, simple short title>

You should include the unit of measure in the title or subtitle. For example Sales by Region ($ in millions). Often the unit is mentioned in a smaller font in the axis title. Mentioning it in the chart title gives the unit more visual prominence.

When a chart shows data for a set period of time, such as Year to Date include that in your title or subtitle. 

<C102 insert image – chart subtitle no date, subtitle with YTD >

Where the data or the date period can change in your chart based on user interactions, such as filtering or drill down, consider using dynamic titles to highlight the details of the chart. For example use a dynamic filter to highlight that the subject of the chart is a particular store – based on the filter values.
