Bubble Chart

The Chart.js Bubble Chart macro can show several data sets of bubbles. The bubbles of each data set have a different color, indicated by the legend above the matrix. Each bubble is based on three values, its x-coordinate, its y-coordinate and its radius. A mouse-over tooltip shows these three values and the data set name it belongs to.

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.
Bubble Border Width
The bubbles 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.
Bubble Hover Border Width
When you hover a bubble 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.
Aspect Ratio
With this option switched on, you can force the height to be the same as the width of the chart (square display).

The table must have a header row. It serves a visual purpose only though and the macro will ignore it.
The table must have at least 5 columns. You can add more if you want for your own purposes but the App will only read the first five and interpret them as follows. Each row represents one bubble.
