javascript - Create SVG circle using path with 6 segments

Question

how to create circle using svg with multiple path with 6 segments in angular 7. Each segments have different path and also gap in between each segment. refer below link for reference. Want to use same image for svg element. how to create in angular 7?

Answer 1

This is how I would do it: I'm creating a path id="segment" and I'm using and rotate it 6 times:

let R = 45;// the outer radius
let r = 15;// the inner radius
//the radius for the text
let textR = r + (R - r)/2
// the angle for the slice
let A = Math.PI/3;
//points used to draw a slice
let p1 = {}
let p2 = {}
let p3 = {}
let p4 = {}
p1.x = r*Math.cos(-A/2);
p1.y = r*Math.sin(-A/2);
p2.x = R*Math.cos(-A/2);
p2.y = R*Math.sin(-A/2);
p3.x = R*Math.cos(A/2);
p3.y = R*Math.sin(A/2);
p4.x = r*Math.cos(A/2);
p4.y = r*Math.sin(A/2);
// the d attribute for the slice
let d =`M${p1.x},${p1.y} L${p2.x},${p2.y} A${R},${R} 0 0 1 ${p3.x},${p3.y} L${p4.x},${p4.y} A${r},${r} 0 0 0 ${p1.x},${p1.y}`;
// set the d attribute for the slice
sectorpath.setAttributeNS(null,"d", d);


// set the x and y attributes for the text
let text = document.querySelectorAll("#txt text")

text.forEach((t,i) =>{
  let x = textR * Math.cos(A*i - Math.PI/2);
  let y = textR * Math.sin(A*i - Math.PI/2);
  
  t.setAttributeNS(null,"x",x);
  t.setAttributeNS(null,"y",y);
})

svg{border:1px solid}
use{fill:blue; stroke:white; stroke-width:3}

<svg viewBox="-50 -50 100 100" width="300" >
  <defs>
    <path id="sectorpath" />
    <mask id="themask">
    <use xlink:href="#sectorpath" style="stroke:#000; stroke-width:3; fill: #ffffff"/>
    </mask>
    <use xlink:href="#sectorpath" id="sector" fill="blue" style="mask: url(#themask)"  />
  </defs>
  
  
  <use xlink:href="#sector" transform="rotate(-90)" />
  <use xlink:href="#sector" transform="rotate(-30)" />
  <use xlink:href="#sector" transform="rotate(30)" />
  <use xlink:href="#sector" transform="rotate(90)" />
  <use xlink:href="#sector" transform="rotate(150)" />
  <use xlink:href="#sector" transform="rotate(210)" />

    
</svg>
