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.
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”.
Enter the title of the chart. You can chose to display it or not by the “Show Title” checkbox.
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.
Enter the thickness of the line in pixel. Enter 0 for none.
Enter the radius of the value points in pixel. Enter 0 for none (continuous line).
Point Hover Radius
Enter the radius of the value points in pixel when hovered.
Point Border Width
Each point has a 1 pixel white border to separate it from the line. You can enter a higher pixel value here. 0 will default to the minimum of 1. (Note: If you want a continuous line, set the point radius to 0.)
Point Hover Border Width
Enter the width of the value points when hovered over them in pixel. Enter 0 for no border.
Fill Line Area
Select whether to use a background color for the area below the lines.
Check this option if you want straight lines from point to point instead of a Bezier curve.
With this option switched on, you can force the height to be the same as the width of the chart (square display).
Select whether you want to show the legend or not.
Select where to show the legend.
Select whether you want to show the tooltips when hovering a bubble or not.
Show Data Table
Select whether you want to show the data table of the macro body in the page view or not.
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:
The table must have a header row. The first two cells are ignored. The rest are used to label line point of the chart.
Each subsequent row describes a data series. The label, color and its values.
The label of this series
The first value (its label is taken from the header row)
The second value (its label is taken from the header row)
