QUESTION
I am currently a bit stuck! Lets say, have a grid of shapes (nested For-Loop) and I want to use a wave to animate it. The wave should have an offset. So far, i can achieve it. Currently the offset affects the Y-axis … But how can I manage to have a RADIAL offset – you know – like the clock hand, or a radar line… I really would like the offset to start from (width/2, height/2) – and then walks around clockwise. Here is my code and the point where I am stuck:
...ANSWER
Answered 2021-Jun-14 at 18:00Right now, you're defining the size of the ellipses based on a transformation of sin(y). A transformation means it looks like a * sin(b * y + c) + d, and in this case you have
a = tileSize / 2b = 300 / 60 = 5c = frameCountd = tileSize / 2
If you want to do a different pattern, you need to use a transformation of sin(theta) where theta is the "angle" of the dot (I put "angle" in quotes because it's really the angle from the vector from the center to the dot and some reference vector).
I suggest using the atan2() function.

I'm trying to make a radar chart using quickchart.io. I accomplished the look I want on raw html, but for some reason, quickchart doesn't like it when it comes to radial option :(
...ANSWER
Answered 2021-Jun-01 at 08:43quickchart.io defaults to latest Chart.js v2 according to their documentation. Therefore, your chart options need to be written as follows. Alternatively you can try to define the version parameter to explicitly tell quickchart.io to use Chart.js v3.

I'd like to get specific an array with onClick but the results always is undefined. if the explanation is unclear, tell me please. i will fix it ! Thanks here is the code
...ANSWER
Answered 2021-May-27 at 13:54your onClick is actually grabbing the html element, that's why you're not getting any matches, when you click a particular h1, it returns
Foo. To get the correct target you need e.currentTarget.innerText. Also since you are using React, please add a unique key prop to the iterated items.

I'm trying to create empty space inside the center circle of the radar chart. Ideally, I want the axis to start at 1 radius (the first circular line) or the stoke to be 0 for the first radius. Thank you for the help.

QUESTION
My chart was rendering last night. Now, it will sometimes render fully, sometimes partially, or often not at all. I am getting no errors in the dev tools. I copied my d3 code to a simple javascript file, with only the latest d3 scripts, and it works. Any insight would be appreciated. Thanks so much in advance.

Answered 2021-May-25 at 19:58You can run the D3 code inside your RadarChart component only when it's properly mounted:

I am trying to replicate the example here by Nadieh Bremer which is a radar chart made in D3.js.
The data structure which is used in Nadieh's example is:
...ANSWER
Answered 2021-May-25 at 13:06You can just use a standard .map and for every pair returned from Array.from(d3.group(...)) return the 2nd item of that pair. For the 2nd item in each pair use index [1] because arrays are zero-based indices.
The working example aligns to the data structure in Nadieh Bremer's block:
QUESTION
I'm trying to program a layout for radar in Kivy 2.0.0 with python 3.6.8 and everything is looking fine until I try to add dots to my layout. Instead of being in the right position, they keep getting centered. Does anybody know the reason why that is happening?
I based my code on this rotating line example: Example
Is there a way for those dots to be positioned by their "pos" value?

Answered 2021-May-23 at 19:02You haven't provided a pos for the Ellipse, so the default (0,0) is used. Try adding pos to your rule:

I have a script to download consecutive satellite and radar images as they come online, later combine them into satellite image animation and radar image animation. I created two separate scripts to download images from satellite and radar. I run these from the shell script same time.
