I have used doughnut chart in my application, I need border radius but not working, I am using this borderRadius:30, could you please solve this issues.
$(function() {
//get the doughnut chart canvas
var ctx1 = $("#doughnut-chartcanvas-1");
//doughnut chart data
var data1 = {
labels: ["match1", "match2", "match3", "match4", "match5"],
datasets: [{
label: "TeamA Score",
borderRadius: 30,
data: [10, 50, 25, 70, 40],
backgroundColor: [
"#DEB887",

],
borderColor: [
"#CDA776",
"#989898",
"#CB252B",
"#E39371",
"#1D7A46"
]
}]
};
//options
var options = {
responsive: true,
title: {
display: true,
position: "top",
text: "Doughnut Chart",
fontSize: 18,
fontColor: "#111",
},
borderRadius: 100,
legend: {
display: true,
position: "bottom",
labels: {
fontColor: "#333",
fontSize: 16
}
}
};
//create Chart class object
var chart1 = new Chart(ctx1, {
type: "doughnut",
data: data1,

I need bend each corner in our doughnut chart . So how to use this properties inside of our code (outerStart, outerEnd, innerStart, innerRight). could you please let me know. How do I solve this.
You can use:
var data1 = {
borderRadius: [{ innerEnd: 200, outerEnd: 200, innerStart: 200, outerStart: 200}],
spacing: -300,
}

I have created a chart using the HighCharts javascript library, the problem I have is that my y-Axis labels are cut by the Y-Axis vertical line. I would like to add more space in the y-axis label gutter area to allow for the labels to be fully visible and so i can add some annotations to the in that area, see image below:
Ideally I would like to add 40px, to the Y-Axis gutter. I have read through the api reference and tried using "yAxis.labels.padding", "yAxis.margin" and "yAxis.offset".
My code is as follows:

Been banging my head around this for while, but I cant seem to figure it out any help would be very much appreciated. Thanks
In Highstock, the yAxis is inverted by default, so aligning the labels is reversed as well.
The only thing you need to change is setting yAxis.labels.align to 'left'.

I am experimenting with Chart.js to build radar charts. I mastered the basics (see basic chart below), but I would like to use the x y coordinates of the graph to place texts directly on the canvas.
After some digging, I found out that it is not possible to use getValueForPixel or getPixelForTick in a radar chart. See this github issue. In the connecting thread, a new method getValueForDistanceFromCenter is introduced.
As I understand it, it would be possible to calculate the distance from the center with this method, and use it to get coordinates. I searched the Chart.js documentation and other sites, but cannot find any code examples or information on how to implement this.
Can somebody point me in the right direction how to implement the method in the code?
var data = {
labels: ["Ball Skills", "Shooting", "Physical"],
datasets: [{
label: [`ikke`, `jij`],
backgroundColor: "rgba(38,120,255,0.2)",
borderColor: "rgba(38,120,255, 1)",
data: [90, 90, 90]
}]
};
var options = {
responsive: true,
tooltips: false,
title: {
text: 'Basic example',
display: true,
position: `bottom`,
},
scale: {
angleLines: {
display: true
},
ticks: {
suggestedMin: 0,
suggestedMax: 100,
stepSize: 25,
maxTicksLimit: 11,
display: false,
}
},
legend: {
labels: {
padding: 10,
fontSize: 14,
lineHeight: 30,
},
},
};
var myChart = new Chart(document.getElementById("chart"), {
type: 'radar',
data: data,
options: options
});
The radialLinear scale (in version 2.9.4 that I have seen your are using version 2) there is the method getValueForDistanceFromCenter(value) to get the distance from center but there is another method getPointPositionForValue(index, value) which can provide you the point at a specif index of your data.
To use them and to draw what you want on chart using those points, you need to implement a plugin.
In the below snippet, I'm drawing a rect between the points at a specific value.
const ctx = document.getElementById("myChart");
const data = {
labels: ["Ball Skills", "Shooting", "Physical"],
datasets: [{
label: [`ikke`, `jij`],
backgroundColor: "rgba(38,120,255,0.2)",
borderColor: "rgba(38,120,255, 1)",
data: [50, 50, 50]
}]
};
const options = {
responsive: true,
tooltips: false,
title: {
text: 'Basic example',
display: true,
position: `bottom`,
},
scale: {
angleLines: {
display: true
},
ticks: {
suggestedMin: 0,
suggestedMax: 100,
stepSize: 25,
maxTicksLimit: 11,
display: false,
}
},
legend: {
labels: {
padding: 10,
fontSize: 14,
lineHeight: 30,
},
},
};
const plugin = {
id: 'getDistance',
afterDraw(chart) {
const c = chart.ctx;
const rScale = chart.scale;
c.save();
chart.data.datasets[0].data.forEach(function(item, index) {
const point = rScale.getPointPositionForValue(0.5 + index, 50);
c.beginPath();
c.fillStyle = 'red';
c.fillRect(point.x - 5, point.y - 5, 10, 10);
c.fill();
});
c.restore();
}
};
const myChart = new Chart(ctx, {
type: 'radar',
plugins: [plugin],
data: data,
options: options
});

I use chart.js for creating this chart:
I want to change the position of two legends( legend1 and legend2), but it did not work!
NOTE: all features work correctly, but problem is that I can't change position of legends:
the version of CDN chart.js :
<script src="https://cdn.jsdelivr.net/npm/chart.js#3.7.1/dist/chart.min.js"></script>
I can't understand, what is the problem? Is it because of it's CDN package version?
my pure js code:

const ctx = document.getElementById('myChart').getContext('2d');
const myChart = new Chart(ctx, {
data: {
labels: ['۱۴۰۰/۰۱/۰۱', '۱۴۰۰/۰۱/۰۲', '۱۴۰۰/۰۱/۰۳', '۱۴۰۰/۰۱/۰۴', '۱۴۰۰/۰۱/۰۵', '۱۴۰۰/۰۱/۰۶'],
datasets: [{
type: 'line',
label: 'legend1',
data: [6, 5.5, 4, 7, 5.4, 5.8],
fill:false,
borderColor: 'rgb(14, 156, 255)',
tension:0 },
{
type: 'line',
label: 'legend2',
data: [6.2, 5.7, 3.8, 7.2, 5.2, 5.9],
fill:false,
borderColor: 'rgb(22, 185, 156)',

} ]
},
options: {
legend: {
position: 'bottom',
}, // end: legend
scales: {
y: {
beginAtZero: true,
display: false }// end: y
,x: {

lineWidth: 1,
color:'#CCCCCC' }// end grid
}//end:x
} // end: scales
} //end options
});
</script>
</body>

I believe it needs to be set under the plugins property in options, like
options: {
plugins: { /// PUT LEGEND UNDER THIS PROP
legend: {
position: 'bottom',
}
},
scales: {
y: {
beginAtZero: true,
display: false }// end: y
,x: {
grid: {
borderDash: [6, 5],
lineWidth: 1,
color:'#CCCCCC' }// end grid
}//end:x
} // end: scales
} //end options
I am trying to make my ChartJS Pie chart responsive on mobile. All the labels and titles scale ok, but when it comes to the actual chart
it looks like this.
This is what I am aiming for it to look like.
I tried changing aspect ratios and responsiveness true/false values, but that didn't do anything.
Does anyone know what could be the issue here?

I have a large data set which, when graphed have several vertical sections as shown below. Chart.js formats these sections with thin, semi-transparent coloring. I want to format these to match the regular, thicker and solid line style.
The dataset itself is normally in a separate file called data.js, but I linked a portion of it from a CodePen.

I figured it out, what you're seeing when you look at the graph is actually mostly just the individual points. Due to the large number of point data, it wasn't apparent at first, but the lines were thinner than the points width.
The vertical lines being so much thinner are actually because those are formatted with the line settings. By setting the transparency of the points color and border to 0, and by reformatting the line settings, I got was able to format it the way I intended. Sample below for reference should anyone else have a similar issue in the future.
