Macro Options

Option	Description
Chart ID	Enter a unique identifier for this chart on your page. If you use more than one Chart.js chart on your page, make sure that each one of them has a different Chart ID. Use no blanks or special characters.
Show Title	Switch on or off the display of the chart title. If switched on (default), the title is shown above the chart’s matrix as shown in the screenshot above: “My Chart.js Bubble Chart”.
Chart Title	Enter the title of the chart. You can chose to display it or not by the “Show Title” checkbox.
Chart Width	This value defines the width of the chart block. The chart itself will adjust to this size. You can enter a pixel (e.g. “500px”) or a percentage (e.g. “100%”) value. A pixel value will make the block exactly that size, a percentage value refers to the parent block, e.g. a Confluence page section. The default is “500px”. Enter the value without the quotes.
Chart Border Width	The chart can have a border if you want so. Enter the size of it here in pixel. Enter just the number without the “px”, e.g. “1”. The default is “1”. Enter the value without the quotes.
Chart Border Color	If you chose to display a border around the chart, you can enter the color of it here. Enter the hex value of the color starting with a “#”, e.g. “#d7d7d7”. Enter the value without the quotes.
Bar Border Width	Enter the size of the bar border width here in pixel. Enter just the number without the “px”, e.g. “1”. The default is “1”. Enter the value without the quotes.
Bar Hover Border Width	When you hover a bar with your mouse its border width can be changed in size with this value. Enter the size of it here in pixel. Enter just the number without the “px”, e.g. “2”. The default is “2”. Enter the value without the quotes.
Line Background	When you use a line instead of bars for a series, the area below the line will have a background color when you tick this option.

Data Table

The macro requires a table with your data in the macro body. It needs to follow a certain format. Here is an example used for the above screenshot:

Series	Type	Color	Apples	Oranges	Bananas	Mangos	Grapes
Maximum	bar	maroon	19	29	40	34	24
Minimum	line	blue	10	12	20	14	4

Header Row

The table must have a header row. The first three cells are ignored. The rest are used to label each bar of the chart.

Rows and Columns

Each row describes a data series. The name of it, the chart type of it, the color of it and its values.

Series	Type	Color	Apples	Oranges	…
The name of this series	The chart type of this series: ‘bar’ or ‘line’	The color of this series. Use ‘random’ or one of the web colors.	The first value (its label is taken from the header row)	The second value (its label is taken from the header row)	…
