QUESTION
I am using the SVGRenderer to draw the total value in the center of donut chart shown below:
The code to do this is shown below (please see CodeSandbox here)
...ANSWER
Answered 2021-Jan-25 at 13:11I can suggest two options for this case:
- Use the
events.render
callback, destroy and render a new label after each redraw:
Demo: https://jsfiddle.net/BlackLabel/ps97bxkg/
- Use the
events.render
callback to trasnlate those labels after each redraw:
Demo: https://jsfiddle.net/BlackLabel/6kwag80z/
Render callback triggers after each chart redraw, so it is fully useful in this case - more information API: https://api.highcharts.com/highcharts/chart.events.render
QUESTION
I am trying to create a pie chart of size 320 x 320 px as shown below:
When a pie is selected, it should expand like this:
What I have been able to achieve so far is shown below, which is obviously too far from the spirit of the design. I am not sure what levers to pull to get as close as possible to the requirements. Please see my CodeSandbox here.
The high-level requirements are:
- Chart size: 320 x 320 px
- Donut diameter: 152px
- Font family: Overpass
- Font sizes:
- General: 12px
- Title: 16px
- Total count: 32px
Some questions I have:
- How to reduce the size of the "ticks" so that the ellipsis on category labels are avoided. Or is there a way to wrap the category labels to avoid the ellipsis?
- How to add the data value to each spending category?
- How to add the total value in the middle?
- How to control font sizes on each element?
- How to grow a pie when selected?
- How to suppress the animations on hover?
My implementation so far is here.
Update
After further research and incorporating changes suggested by @Sebastian Wędzel, I have been able to bring the implementation upto the following level:

Answered 2021-Jan-20 at 09:40I see that you already found most of the answers to your questions. Here are my proposals for unanswered questions:
- Chart size: 320 x 320 px - you can define the
chart.width
andchart.height
API: https://api.highcharts.com/highcharts/chart.width
-
How to add the total value in the middle?
You can render it as a custom text by using the SVGRenderer tool.
Demo: https://jsfiddle.net/BlackLabel/xbhas3g6/
API: https://api.highcharts.com/class-reference/Highcharts.SVGRenderer#text
-
How to grow a pie when selected?
Here you probably will need to change your series type to the variablepie
- demo: https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/demo/variable-radius-pie and implement the point.update
on the click event to increase selected point Z value.

QUESTION
I'm having trouble recreating this answer in R with Highcharter to make the bars in a bar chart into clickable URLs. Here is the Javascript code from the answer. Highcharter has a vignette about recreating Javascript that I tried to follow. Here's what tried so far. It doesn't show any of the bars.

Answered 2018-Jan-19 at 19:00Andrew,
You have some (2) errors replicating the example:
- If you check carefully the example you gave. The
point
argument lives at the same depth ofcursor
in theseries
argument. - You didn't add the data in the correct way (like the vignette show).
A fixed version of your code is:
