I made a pine script for trading view indicator. I want it to plot an uninterrupted line, however I see interrupted line (dashed line) being plotted. I don't know how to resolve this.
I follow the pine script Version 5 user manual on tradingview, but couldn't track the problem.

I want to add a custom profile avatar to one of my projects. I tried with the custom painter & clipper. But, when I test in different devices the shape & size are not as my designer gave to me.
This is my painter class.
import 'package:flutter/material.dart';
class ProfileBox extends CustomPainter {
#override
void paint(Canvas canvas, Size size) {
final paint = Paint();
paint.color = Colors.grey;
paint.style = PaintingStyle.fill;
final path = Path();
path.moveTo(25, 4);
path.quadraticBezierTo(size.width / 2, -4, size.width - 25, 4);
path.quadraticBezierTo(size.width - 10, 10, size.width - 4, 25);
path.quadraticBezierTo(
size.width + 4, size.height / 2, size.width - 4, size.height - 25);
path.quadraticBezierTo(
size.width - 10, size.width - 10, size.width - 25, size.height - 4);
path.quadraticBezierTo(
size.width / 2, size.height + 4, 25, size.height - 4);
path.quadraticBezierTo(10, size.height - 10, 4, size.height - 25);
path.quadraticBezierTo(-4, size.height / 2, 4, 25);
path.quadraticBezierTo(10, 10, 25, 4);
canvas.drawPath(path, paint);
}
#override
bool shouldRepaint(CustomPainter oldDelegate) {
return this != oldDelegate;
}
}
This is my clipper class.
import 'package:invoice_app/constants/globals.dart';
class ProfileClipper extends CustomClipper<Path> {
ProfileClipper({#required this.profileSize});
final ProfileSize profileSize;
#override
Path getClip(Size size) {
final path = Path();
path.moveTo(23, 2);
path.quadraticBezierTo(size.width / 2, -4, size.width - 23, 2);
path.quadraticBezierTo(size.width - 8, 8, size.width - 2, 23);
path.quadraticBezierTo(
size.width + 4, size.height / 2, size.width - 2, size.height - 23);
path.quadraticBezierTo(
size.width - 8, size.width - 8, size.width - 23, size.height - 2);
path.quadraticBezierTo(
size.width / 2, size.height + 4, 23, size.height - 2);
path.quadraticBezierTo(8, size.height - 8, 2, size.height - 23);
path.quadraticBezierTo(-4, size.height / 2, 2, 23);
path.quadraticBezierTo(8, 8, 23, 2);
return path;
}
#override
bool shouldReclip(covariant CustomClipper<Path> oldClipper) => false;
}
And, I'm using it in UI with the below widget.
painter: ProfileBox(),
child: Container(
padding: const EdgeInsets.all(5),
height: 100,
width: 100,
child: ClipPath(
clipper: ProfileClipper(profileSize: ProfileSize.smallProfile),
child: Container(
// if image url is null and want to display icon or svg then add padding
padding: _imageFile != null
? const EdgeInsets.all(0)
: const EdgeInsets.all(13),
// color: Colors.blue,
child: Image(
// if image url is null then display icon or svg
image: _imageFile != null
? FileImage(_imageFile)
: AssetImage(
'assets/defaultbusiness.png',
),
fit: BoxFit.fill,
),
),
),
),
),

I tried both on scaled and non-scale values:
fviz_nbclust(scale(tab), kmeans, method = "wss")
fviz_nbclust(tab, kmeans, method = "wss")
and I get this error:
Error in FUNcluster(x, i, ...) :
more cluster centers than distinct data points.
how can I fix it?
Many thanks for your help !
I maybe found the solutions: it was sufficient to specify k.max = any number lower than nrow(tab)
I wanted to draw a hexagon shape but I couldn't do what I wanted.
this is my result:
Path createHexagonPath() {
const int SIDES_OF_HEXAGON = 6;
const double radius = 50;
const Offset center = Offset(50, 50);
final path = Path();
var angle = (pi * 2) / SIDES_OF_HEXAGON;
Offset firstPoint = Offset(radius * cos(0.0), radius * sin(0.0));
path.moveTo(firstPoint.dx + center.dx, firstPoint.dy + center.dy);
for (int i = 1; i <= SIDES_OF_HEXAGON; i++) {
double x = radius * cos(angle * i) + center.dx;
double y = radius * sin(angle * i) + center.dy;
path.lineTo(x, y);
}
path.close();
return path;
}
I want that to be the case:
go over to this website https://fluttershapemaker.com it is simple and easy
you can try this, polygon_clipper with flutter_neumorphic
Neumorphic(

So, I've created a shape using drawPath and drawArc from CustomPainter, the PaintingStyle is stroke, but when I change it to fill, it only fills the arcs and not the whole shape.
I want to fill the shape I created with a color, so how can I fill the shape with a particular color?

final Color color;

When the PaintingStyle is stroke, I get this,
When I change PaintingStyle to fill, I get,
