QUESTION
After thoroughly reading the Chart.js documentation, I didn't find any method to get the innerRadius
of a doughnut chart.
This is one of the many issues I found after migrating from Chart.js 2.x to 3.x
In Chart.js 2.x, to get the inner radius of a doughnut chart, I would do:

Answered 2022-Apr-15 at 08:56Each dataset has its own controller so there is no global single doughnut controller. So if you want to get the controller you need to get it from the meta of the dataset:

QUESTION
My study colleague and I are working on creating some doughnut graphs, and want to use mouseOver to print the values of doughnut slices. The calculations we are using are in radians (using angleMode(RADIANS). To track the mouse position, we are calculating the mouseX and mouseY positions, and also a 'mouse angle' as the angleBetween comparing a vector(1, 0) and a vector of mouseX, mouseY. For me, the result is positive radians clockwise from 3.00 o'clock to 9.00 o'clock, and then negative radians for the opposite. However, for my study colleague they are getting absolute values in radians. We found a GitHub detailing a bug in this function from August 2019: (https://github.com/processing/p5.js/issues/3973) My colleague implemented a fix checking on the overall position of Y before calling the angleBetween function, but this is obviously not optimal.
Has anyone else encountered this issue, and know why this is happening?
Thanks!
...ANSWER
Answered 2022-Mar-17 at 20:46Older versions of the p5.js library the angleBetween
function had different behavior (only return the absolute value of the angle irrespective of direction). However as of version 0.10.0, angleBetween
will return a signed value depending on whether the second vector is clockwise or counter clockwise of the first vector (see pull request #4048). So the solution is to make sure they everyone is using the same, recent, version of p5.js.
QUESTION
I'm trying to build a doughnut chart with rounded edges only on one side. My problem is that I have both sided rounded and not just on the one side. Also can't figure out how to do more foreground arcs not just one.
...ANSWER
Answered 2022-Feb-28 at 08:52The documentation states, that the corner radius is applied to both ends of the arc. Additionally, you want the arcs to overlap, which is also not the case.
You can add the one-sided rounded corners the following way:
- Use arcs
arc
with no corner radius for the data. - Add additional
path
objectscorner
just for the rounded corner. These need to be shifted to the end of eacharc
. - Since
corner
has rounded corners on both sides, add aclipPath
that clips half of this arc. TheclipPath
contains apath
for everycorner
. This is essential for arcs smaller than two times the length of the rounded corners. raise
all elements ofcorner
to the front and thensort
them descending by index, so that they overlap the right way.

Either you can remove it, if not you can try below solution

QUESTION
I am working on a doughnut circle svg with expanding tabs. As of last night the expanding tabs are fully functional and the correct x/y transform is applied on mouseenter/mouseleave. (the x/y is essential on both mouse enter and mouse leave for proper transform origin - this was difficult to get each tab expansion to appear centered as it is a circle).
Today I have tried going further with the project by creating an additional loop that displays corresponding content based on the active tab index. (This is working).
Now I want to go a step further by making the current tab stay expanded until another tab is hovered over. Right now the eventlistener mouseleave applies when my mouse leaves the tab (obviously). What can I do to keep the current tab "active" unless hovering over another tab? (rather than the mouseleave?). I am still fairly inexperienced with JS, I'll be content if anyone could just send me in the right direction
...ANSWER
Answered 2022-Jan-26 at 18:29Instead of using the mouseout
event here, you will have to use a "custom event".
Yes, you can create events... Read more here and dispatch them. That allows you to trigger something special without interfering with the "normal behavior" of any other regular event.
Below, I called the event "retract". Yay! You also can name it like you wish!
Here is the function:
QUESTION
I am attempting to animate an svg doughnut circle with gsap. After much testing with code and layering, I am stumped with a glitchy hover effect (which I tried to resolve with pointer events) and the transform origin is only applied to a few of the expanded tabs. I am wondering if this might be that the tabs may have a different bounding box?
Comments added per request:
Side Note: I've tried applying fill-box to entire svg instead, I'm wondering if I need a parent layer thats an exact square so I can apply the transform origin for the child "expandtabs" to the center of that?
I assumed I needed to iterate through an array of both to have the tabs correspond. Unless the tabs were children of each other?
TLDR; Tabs are not scaling from center of circle, and glitchy hover effect
...ANSWER
Answered 2022-Jan-26 at 01:54About the glitchy hover effect, the mouseenter
and mouseleave
will do the job better. mouseover
is firering way to much...
For the "growing" effect, it is more complex. The transform-origin
CSS property won't be enought. Any way, you will need different values for each five parts of the circle.
Additionnaly, you will need to adjust a transition to "fit" or "keep" the inner part of the circle in place. I suggest you to look at the fromTo method of GSAP. That will allow you to specify explicitely the starting and the landing coordinates.
Be patient! ;)
QUESTION
HTML
...ANSWER
Answered 2022-Jan-25 at 12:04This is because you did not disable the legend, title or tooltip. If you hover your chart you can see the tooltip is still working, title is hidden by default. Why the legend does not show I dont really know, should still show 1 item with undefined as text. But if you disable it in the correct space with is the plugins
namespace you see your extra padding goes away.
Also cutout and responsive have to be configured in the options not in the root of new Chart:
