I'm trying to make an area chart using apexcharts with nuxt (vue2), but the area is not getting filled, and the options i set in chartOptions for fill are getting used by the line itself instead of the area, as below:
this is my apexchart component:
<client-only>
<apexcharts
type="area"
width="70%"
ref="realtimeChart"
:options="chartOptions"
:series="series">
</apexcharts>
</client-only>
this is my chartOptions:
chartOptions: {
chart: {
toolbar: {
show: true,
tools: {
download: true,
selection: false,
zoom: true,
zoomin: false,
zoomout: false,
pan: false,
reset: false,
},
},
id: "basic-bar",
colors: ["#FFA07A"],
fill: {
type: "gradient",
gradient: {
shadeIntensity: 1,
opacityFrom: 0.7,
opacityTo: 0.9,
stops: [0, 100],
},
},
forecastDataPoints: {
count: 28,
strokeWidth: 4,
dashArray: 5,
},
title: {
text: "doesnt matter",
align: "center",
},
grid: {
borderColor: "#e7e7e7",
row: {
colors: ["#f3f3f3", "transparent"],
opacity: 0.5,
},
},
xaxis: {
type: "date",
tickAmount: 40,
},
yaxis: [
{
title: {
text: "Mt CO2eq/we",
},
forceNiceScale: true,
},
]
},
Can anyone help ?
I was declaring type: "line" in my series. thats all.

Fairly straightforward, but I have a single bar on a barchart that I want to show by itself. I've hidden the axes and their ticks, but there is still all of that space there on the left and top//bottom of chart from the axes and the legend I am presuming.
Is there a way to remove this space without just putting negative margins on the element?
I've tried working with negative padding, but that doesn't work on the top and bottom of the chart.
I made a quick CodeSandbox to show my actual component
Any tips would be greatly appreciated!
Cheers!

This is because you set barThickness to 20 in your datasets. If you remove this it will show as you want:

I have a bar chart and I would like to change the font color, border width and some other tings, but it doesn't work. It is in my computed property. In the chartOptions I want to change the y axis min and max value but I don't know if it is correct. Can anyone help me?
Also I want to make a horizontal line in this bar chart. It is the "Enemy's Avarage" and now it is a constant. I set the type to line and now I have a dot in my chart.
This is my chart component:
<script>
import { defineComponent } from 'vue'
import { Bar } from 'vue3-chart-v2'
export default defineComponent({
name: 'ChanceChart',
extends: Bar,
props: {
chartData: {
type: Object,
required: true
},
chartOptions: {
type: Object,
required: false,
},
},
mounted () {
this.renderChart(this.chartData, this.chartOptions)
}
})
</script>
And this is my app:
<template>
<div id="chart">
<ChanceChart :chartData="chartData" :chartOptions="chartOptions" />
</div>
</template>
<script>
import Navigation from "../components/Navigation.vue";
import ChanceChart from "../components/ChanceChart.vue";
import PageLoader from "../components/PageLoader.vue";
export default {
components: {
ChanceChart,
},
computed: {
chartOptions() {
return {
options: {
scales: {
y: {
title: {
display: true,
text: 'Value'
},
min: 0,
max: 100,
ticks: {
stepSize: 10,
}
},
},
elements: {
point: {
radius: 0
},
line: {
borderWidth: 2
}
},
plugins: {
legend: {
labels: {
boxWidth: 0,
font: {
fontColor: "#fff",
color: "#fff"
},
},
},
},
}
}
},
chartData() {
return {
datasets: [
{
type: 'bar',
label: "Enemy's Chance",
borderColor: "#1161ed",
borderWidth: 2,
data: this.emnemyCardsFilled,
},
{
type: 'bar',
label: "My Chance",
borderColor: "#f87979",
borderWidth: 2,
data: this.myCardsFilled,
},
{
type: 'line',
label: "Enemy's Avarage",
borderColor: "rgb(238, 255, 0)",
borderWidth: 2,
data: [50],
},
],
}
},
},
You need to remove the options part in the computed chartOptions prop:
chartOptions() {
return {
scales: {
y: {
title: {
display: true,
text: 'Value'
},
min: 0,
max: 100,
ticks: {
stepSize: 10,
}
},
},
elements: {
point: {
radius: 0
},
line: {
borderWidth: 2
}
},
plugins: {
legend: {
labels: {
boxWidth: 0,
font: {
fontColor: "#fff",
color: "#fff"
},
},
},
},
}
},
I am creating simple bar chart using Chartjs in Vue
<bar-chart
:data="[40, 19, 3, 5,]"
:labels="['0-30 days', '31-60 days', '61-90 days', '90+']"
:colors="['blue', 'blue', 'blue', 'blue']"
></bar-chart>
and the code for this is
createChart(chartData: object) {
const canvas = document.getElementById('bar') as HTMLCanvasElement;
const myopt = {
deferred: {
xOffset: '50%',
delay: 250,
},
plugins: {
datalabels: {
align: 'top',
anchor: 'end',
color: 'blue',
},
},
legend: {
display: true,
},
title: {
display: true,
text: 'Chart.js - Different Bar Colors',
},
tooltips: { enabled: true },
responsive: true,
hover: { mode: null },
elements: {
point: {
radius: 0,
},
},
scales: {
xAxes: [{
scaleLabel: {
display: true,
labelString: '',
},
offset: false,
color: 'rgba(0, 0, 0, 0)',
gridLines: {
drawOnChartArea: false,
},
}],
yAxes: [{
id: 'y-axis-0',
mirror: false,
stacked: true,
offset: false,
callback(label:any, index:any, labels:[]) {
return `${label}%`;
},
ticks: {
beginAtZero: true,
min: 0,
},
gridLines: {
display: true,
color: 'rgba(0, 0, 0, 0)',
drawOnChartArea: false,
},
}],
},
};
const options = {
type: 'bar',
data: chartData,
options: myopt,
};
new Chart(canvas, options);
}
the chart which this is generating is not equidistant sharing image for reference
position and width of the bar is incorrect and also I want to know if there is any way by which i can customize labels for y axis e.g. instead of 40,35,30... it will be ** 40k,35k,30k** in y axis
If any one has worked on this case please help
You can make use of the tick callback for your K at the end (https://www.chartjs.org/docs/latest/axes/labelling.html#creating-custom-tick-formats)
var ctx2 = document.getElementById("stack-chart");
var stackChart1 = new Chart(ctx2, {
type: 'bar',
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero: true,
callback: (val) => (val + 'k')
}
}]
},
legend: {
display: false,
labels: {
fontSize: 20,
fontColor: '#595d6e',
}
},
tooltips: {
enabled: false
}
},
data: {
labels: ['1', '2', '3', '4', '5'],
datasets: [{
backgroundColor: "#5e63b4",
data: [20, 30, 40, 50, 60]
}]
},
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.9.4/Chart.min.js"></script>
<canvas id="stack-chart" width="1360" height="450"></canvas>
I have the following Chart Component:
<template>
<div class="gauge-chart">
<chart :options="options"></chart>
</div>
</template>
<script>
export default {
props: {
chartValue: { type: Number, required: true },
chartName: { type: String, required: true },
},
data: () => ({
options: {
series: [
{
type: "gauge",
startAngle: 180,
endAngle: 0,
min: 1,
max: 5,
splitNumber: 8,
axisLine: {
lineStyle: {
width: 6,
color: [
[0.25, "#7CFFB2"],
[0.5, "#58D9F9"],
[0.75, "#FDDD60"],
[1, "#FF6E76"],

},
},

offsetCenter: [0, "-30%"],
itemStyle: {

axisTick: {

lineStyle: {

splitLine: {

},
data: [
{
value: this.chartValue,
name: this.chartName,
},
],
},
],
},
}),
};
</script>
As you can see I am tryng to inject chartValue and chartName props into options.series.data.value and options.series.data.name respectively.
The values for the properties are coming from
<GaugeChart chartName="Sleep" :chartValue="2" />
At the moment the values are hardcoded, but eventually they will be dynamic.
However it keep throwing the following error:
"TypeError: Cannot read property 'chartName' of undefined"
"TypeError: Cannot read property 'chartValue' of undefined"
I have done a colsole.log of both properties and they come up as "Sleep" and 2. I have also done a typeof on both property names and they both come up as String and Number, respectively.
Could somebody tell me where I am going wrong please?
Many thanks in advance.
You cannot use 'this' operator inside an arrow function so define your data section as a normal function
<script>
export default {
props: {
chartValue: { type: Number, required: true },
chartName: { type: String, required: true },
},
data() {
return {
options: {
series: [
{
type: "gauge",
startAngle: 180,
endAngle: 0,
min: 1,
max: 5,
splitNumber: 8,
axisLine: {
lineStyle: {
width: 6,
color: [
[0.25, "#7CFFB2"],
[0.5, "#58D9F9"],
[0.75, "#FDDD60"],
[1, "#FF6E76"],
],
},
},
pointer: {
icon: "arrow",
offsetCenter: [0, "-30%"],
itemStyle: {
color: "auto",
},
},
axisTick: {
length: 12,
lineStyle: {
color: "auto",
width: 1,
},
},
splitLine: {
length: 20,
lineStyle: {
color: "auto",
width: 5,
},
},
title: {
fontSize: 30,
},
data: [
{
value: this.chartValue,
name: this.chartName,
},
],
},
],
},
};
}
};
</script>
You should use the prop in following manner:
<GaugeChart chart-name="Sleep" chart-value="2" />

I have an app that worked great for 2.0p5. I was able to set the various columns in the chart specific colors. In the chart config, I added
colors: [
'#89A54E',
'#4572A7',
'#AA4643'
],
When I upgraded to 2.0rc1, the colors no longer seem to get set. My chart config is:
Ext.create('Rally.ui.chart.Chart', {
animate: true,
chartData: {
series: [{
type: 'column',
name: 'Data1',
data: data1
},
{
type: 'column',
name: 'Data2',
data: data2
},
{
type: 'column',
name: 'Data3',
data: data3
}],
categories: xAxisData
},
chartConfig: {
chart: {
type: 'column'
},
title: {
text: 'Show Data'
},
yAxis: {
min: 0,
title: {
text: 'yAxis Info'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: 'gray'
}
}
},
legend: {
align: 'right',
x: -100,
verticalAlign: 'top',
y: 20,
floating: true,
backgroundColor: 'white',
borderColor: '#CCC',
borderWidth: 1,
shadow: false
},
tooltip: {
formatter: function() {
return '<b>'+ this.x +'</b><br/>'+
this.series.name +': '+ this.y +'<br/>'+
'Total: '+ this.point.stackTotal;
}
},
colors: [
'#89A54E',
'#4572A7',
'#AA4643'
],
plotOptions: {
column: {
stacking: 'normal',
dataLabels: {
enabled: true,
color: 'white'
}
}
}
}
});
Any ideas why I lost my color setting capabilities in 2.0rc1?
An example from one of my apps:
var series = [{
name : 'Col 1',
data : [],
showInLegend : false
},{
name : 'Col 2',
data : [],
showInLegend : false
},{
name : 'Col 3',
data : [],
showInLegend : false
}];
Ext.Array.each(records, function(record) {
//HighCharts Data
record.set('name', ...);
record.set('y', ...);
record.set('color', ...);
//Add record to series
series[index].data.push(record.data);
// Add to chartData
});
Hope this helps/works for you!
