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.
Aspect Ratio	With this option switched on, you can force the height to be the same as the width of the chart (square display).
