i have highchart graph api similar to pasted fiddle link, the problem
is number is missing in few stacked column( example in fiddle decission line one label value is missing) could anyone help on this why
this is happening

If I change stacking to percent ,all labels are visible. minPointLength is set to make minimum column stacks width for a relatively less number
use following :
plotOptions: {
column: {
stacking: 'percent',
minPointLength:10 //this needs to added
}
}

Chart.js doughnut text visibility. Tell me how to make it so that when the values intersect, the text comes out and changes its position.
const myChart = new Chart(canvas,
{
type: 'doughnut',
data: {
labels: dataNameDB,
datasets: [{
data: dataCountDB,
backgroundColor: backgroundColor,
borderWidth: 0,
}],
},
plugins: [ChartDataLabels, DoughnutLabel],
options: {
cutout: 340,
responsive: true,
animation: false,
plugins: {
legend: {
display: false,
},
datalabels: {
formatter: (val, ctx) => {
return Math.round((ctx.chart.data.datasets[0].data[ctx.dataIndex] * 100) / summChart()) + "%";
},
display: (val,ctx) =>{
return 'auto';
},
clamp: true,
clip: true,
anchor: 'center',
align: 'center',
offset: 1,
font: {
size: 65,
weight: 'bold',
color: '000000'
},
color: '000000',
labels: {
value: {
color: '#000000'
}
}
},
doughnutlabel: {
labels: [{
text: summChart,
font: {
size: 140,
weight: 'bold',
color: '000000'
}
}]
}
}
}
},
);
Now it outputs something like this, but I need it to be like this:
Although the documentation says that display 'auto' is responsible for this, how to catch it when the text is hidden in order to move it?
I'm trying to customise my chart's legend. My current legend needs to look like this legend.
Basically I need to make the circular icons rectangular and change the legend text color to correspond with the icon.
I've looked everywhere in the docs but I'm not finding a solution. This is how I configured the graph below (legend > itemStyle):
useEffect(() => {
Highcharts.chart(chart.current, {
chart: {
type: 'column',
style: {
fontFamily: '"Roboto", sans-serif',
},
height: 312,
},

},
title: {
text: null,
},
xAxis: {
categories,
labels: {
step: 1,
style: {
fontSize: '8px',
color: '#808992',
},
useHTML: true,
formatter() {
const day = this.value.format('D');
if (moment().isSame(this.value, 'd')) {
return `<strong style="font-weight: 900; color: #0E2C47;">${day}</strong>`;
}
return day;
},
},
gridLineWidth: 1,
},
yAxis: {
min: 0,
title: {
text: `Collections ${showValue ? 'value' : 'count'}`,
style: {

lineHeight: '14.4px',
},
},
labels: {
style: {
fontSize: '8px',
color: '#808992',
},
useHTML: true,
formatter() {
// eslint-disable-next-line react/no-this-in-sfc
const collection = this.value;
const format = Math.abs(collection) > 999 ? `${Math.sign(collection) * ((Math.abs(collection) / 1000).toFixed(1))}K` : Math.sign(collection) * Math.abs(collection);
return `${format}`;
},
},
useHTML: true,
},

},
},
series: [{

data: chartData.draft, // [...times(() => null, 30), ...times(random, 31)],

legendIndex: 0,
}, {

data: chartData.approved,
color: collectionStateColors.approved, // orange
legendIndex: 1,
}, {

data: chartData.expired,

Hell, all,
I would like to draw the chart like this:
Currently, I can use afterBuildTicks to get only zero yAxis. But the problem is that the whole other ticks were removed also. So Not sure if we have a way to draw zero tick and keep other ticks hidden except the label.
var ctx = document.getElementById("myChart").getContext("2d");
var myChart = new Chart(ctx, {
type: 'line',
data: {
labels: ['Value 1', 'Value 2', 'Value 3', 'Value 4'],
datasets: [{
label: "Dataset",
data: [20, 15, 27, 18],
backgroundColor: 'rgba(54, 162, 235,0.5)',
}],
},
options: {
responsive: true,
elements: {
line: {
fill: false
}
},
scales: {
xAxes: [
{
position: 'top',
display: true,
gridLines: {
display: true,
},
stacked: true,
ticks: {
fontColor: "#C4C4C4",
fontSize: 10,
}
}
],
yAxes: [
{
type: 'linear',
display: true,
position: 'right',
id: 'y-axis-1',
gridLines: {
display: true,
},
labels: {
show: true
},
stacked: false,
ticks: {
fontColor: "#C4C4C4",
fontSize: 10,
precision: 0,
suggestedMax: 100,
suggestedMin: -100
},
afterBuildTicks:function (axis) {
axis.ticks = [0]
}
}
]
},
tooltips: {
mode: 'label',
bodySpacing: 10,
titleMarginBottom: 10,
titleFontSize: 14,
titleFontStyle: 'bold',
footerAlign: 'right',
callbacks: {
label: (tooltipItem, data) => {
const label = data.datasets[tooltipItem.datasetIndex].label || ''
const value = tooltipItem.value
return ` ${label}: ${value}`
}
}
}
}
});

Thanks so much
I found the solution that use: gridLines options to draw chart with width is zero:
gridLines: {
display: true,
tickMarkLength: 10,
lineWidth: 0
}
I'm using echarts-for-react to create a gauge. I'm trying to disable the hover effect on the pointer.
The current behaviour is that I have a circle with a small pointer, and when hovering, the pointer covers the text. I've tried setting emphasis: null but it didn't change anything.
Here's the pictures demonstrating this issue:
Normal Behaviour
When hovering
Here's my code:
const series = {
type: 'gauge',
radius: '100%',
startAngle: '-20',
endAngle: '200',
clockWise: false,
data: [ltv],
max: 150,
axisLine: {
show: true,
lineStyle: {
width: '12',
color: [[0.2, '#e2da34'], [0.4, '#c2e234'], [0.6, '#7dea52'], [0.8, '#c2e234'], [1, '#e2da34']],
shadowColor: '#f5f5f5',
shadowBlur: 10,
shadowOffsetX: 5,
shadowOffsetY: 5
}
},
splitLine: {
show: false
},
axisTick: {
show: false
},
axisLabel: {
show: false
},
pointer: {
length: '100%',
width: '4'
},
itemStyle: {
color: '#d1d1d1',
borderWidth: 5,
borderColor: '#d1d1d1'
},
detail: {
show: true,
formatter: e => [`{val|${e.toFixed(1)}%}`, '{text|Good!}'].join('\n'),
rich: {
val: {
color: '#2f353a',
fontWeight: 'bold',
fontFamily: 'SegoePro-Bold',
fontSize: '24'
},
text: {
color: '#9c9c9c',
fontFamily: 'SegoePro-Regular',
fontSize: '12'
}
},
offsetCenter: [0, 0],
padding: [40, 10, 0, 10],
width: 85,
height: 65,
backgroundColor: '#ffffff',
borderWidth: 1,
borderRadius: 50,
borderShadow: '#000000'
}
};
const config = {
title: {
show: false
},
legend: {
show: false
},
tooltip: {
show: false
},
series
};
I have set min:0, in y-axis. But in tooltip i want to show negative values also and also it should start with value y=0 only.
if i will remove min:0 in y axis it will show negative values with tooltip in chart. But i only want to see negative values on tooltip not on chart.
but it is not allowing me to show negative values.
below is sample code.
$(id).highcharts({
chart: {
zoomType: 'xy',
marginLeft: 45,
marginRight: rightval - 10
},
title: { text: title },
exporting: { enabled: false },
credits: { enabled: false },
legend: { enabled: false, align: 'left', x: 10, verticalAlign: 'bottom', y: 3, shadow: false },
xAxis: {
min: minimum,
max: maximum,
scrollbar: {
enabled: scroobarVal
},
fontWeight: 'bold',
categories: Data['categories'],
labels: {
y: 20,
rotation: 0,
style: {
color: 'gray',
//fontSize:'1px !important;'
}
}
},
yAxis: [{
min: 0,
allowDecimals: false,
endOnTick: false,
gridLineWidth: 0,
labels: {
formatter: function () {
if (optionSelected == 'Day') {
return this.value;
} else {
return this.value / 1000000 + 'M';
}
},
style: {
color: '#767676'
}
},
offset: -10,
title: {
text: 'Inv ' + val_qty,
"textAlign": 'top',
"rotation": 0,
x: 60,
y: yaxisVal,
style: {
color: '#767676',
fontWeight: 'bold'
}
}
}, {
allowDecimals: false,
min: 0,
endOnTick: false,
gridLineWidth: 0,
title: {
text: y2axisname,
"textAlign": 'top',
"rotation": 0,
x: -75,
y: yaxisVal,
style: {
color: '#767676',
fontWeight: 'bold'
}
},
offset: -10,
labels: {
format: '{value}',
style: {
color: '#767676'
}
},
opposite: true
}],
labels: {
items: [{
html: ' ',
style: {
color: (Highcharts.theme && Highcharts.theme.textColor) || 'black'
}
}]
},
tooltip: {
style: { fontSize: '7pt' },
formatter: function () {
var s = '<b>' + this.x + '</b>';
$.each(this.points, function (i, point) {
s += '<br/><span style="color:' + point.series.color + '">\u25CF</span> ' + point.series.name + ': <b>' + CurrencySymbol + '</b>' + point.y.toString().replace(/,/g, "").replace(/\B(?=(\d{3})+(?!\d))/g, ", ");
});
return s;
},
shared: true
},
series: Data['series'],
});
I don't think there is a simple way to do this on Highchart.
One hacky way I found (don't judge me!) is to have a "ghost" series and set the tooltip.shared option to true.
