I'm plotting a HighCharts heatmap of a wafer with around 50~70k points (it's like a CPU/processor silicon wafer). I need to put horizontal and vertical gridlines visible on the map, so that our engineers can easily figure out what's going on with the actual unit.
I have two concerns:
Horizontal gridlines are already OK, but the vertical gridlines are not drawn or visible. I thought, I just need to set gridZIndex=4. Kindly see image below - it should be drawn based on xAxis.tickPositions values (similar to yAxis)
I put some color options I found, but none of them could change the grid's color.
So far this is my code:
var option = {
chart: {
type: 'heatmap',
zoomType: 'xy',
},
boost: {
useGPUTranslations: true
},
title: {
text: chrt_title,
align: 'left',
x: 0,
style: {
fontSize: '12px',
}
},
exporting: {
buttons: {
contextButton: {
menuItems: [
'viewFullscreen', 'downloadPNG', 'downloadXLS'
]
}
},
enable: true,
},
xAxis: {
title: {
text: null
},
labels: {
enabled: false,
},
tickPositions: [1, 19, 43, 67, 91, 115, 139, 163, 183],
gridZIndex: 4, // DOESN'T WORK
gridLineDashStyle: 'Dash',
gridLineWidth: 1, // DOESN'T WORK
lineColor: 'red',
minorTickColor: 'red',
tickColor: 'red'
},
yAxis: {
title: {
text: null
},
reversed: true,
labels: {
enabled: false,
},
tickPositions: [1, 82, 116, 174, 272, 370, 428, 462, 544]
gridZIndex: 4, // ONLY PUT THIS AND WORKS ALREADY
gridLineDashStyle: 'Dash', // THIS WORKS TOO (Dot,Solid,etc)
lineColor: 'red',
minorTickColor: 'red',
tickColor: 'red'
},
colorAxis: {
stops: colrstops,
min: minval,
max: maxval,
startOnTick: true,
endOnTick: true,
labels: {
format: '{value}',
style: {
fontSize: '8px',
fontFamily: 'Verdana, sans-serif'
}
}
},
series: [{
boostThreshold: 100,
borderWidth: 0,
nullColor: '#ffffff',
tooltip: {
headerFormat: chrt_title + '<br/>',
pointFormat: 'RB{point.y} SL{point.x} <b>{point.value}</b>'
},
turboThreshold: Number.MAX_VALUE, // #3404, remove after 4.0.5 release
data: data
}]
}
As you can see, both xAxis and yAxis have gridZIndex = 4, gridLineDashStyle = 'Dash', but only the yAxis that gives the horizontal gridlines, no luck for xAxis (assuming this is where need to set the vertical gridlines) :(
the only similar question i found reg vertical gridlines is this one:
Highcharts: xAxis with vertical gridlines
but I tried to put the gridLineWidth=1, still nothin's happening T-T please help. thanks very much.
Update:
I temporarily replaced my option{} based on #ppotaczek sample but vertical gridlines still did not appeared.
Then I played with my own option{}, tried to add min and max in xAxis, and tried to temporarily removed my dynamic data and use #ppotaczek sample, the layout remains the same (no vertical gridlines)..
Also thought it has something to do with the version i'm using..? it's 9.0.1 - so I tried to update to latest 9.1.1, but also have same result.
var option = {
chart: {
type: 'heatmap',
},
xAxis: {
tickPositions: [1, 19, 43, 67, 91, 115, 139, 163, 183],
min: 1,
max: 183,
gridZIndex: 4, // DOESN'T WORK
gridLineDashStyle: 'Dash',
gridLineWidth: 1, // DOESN'T WORK
lineColor: 'red',
minorTickColor: 'red',
tickColor: 'red'
},
yAxis: {
title: {
text: null
},
reversed: true,
labels: {
enabled: false,
},
tickPositions: [1, 82, 116, 174, 272, 370, 428, 462, 544],
gridLineDashStyle: 'Dash', // THIS WORKS TOO (Dot,Solid,etc)
lineColor: 'red',
minorTickColor: 'red',
tickColor: 'red',
},
colorAxis: {},
series: [{
data: [
[10, 0, 1],
[20, 1, 5],
[30, 1, 5],
],
}]
}
I want to change the stroke line color with the data range.
here what I have done with react-native-chart-kit
but I want to like this---V
if you have any idea please let me know
You can use the scriptable backgroundColor and segments for this, you need to improve the calculation a bit on when to show what color but its a basic starting point
Example:
var options = {
type: 'line',
data: {
labels: ["Red", "", "Blue", "", "Yellow", "", "Green", "", "Purple", "", "Orange"],
datasets: [{
label: '# of Votes',
data: [12, 15.5, 19, 11, 3, 4, 5, 3.5, 2, 2.5, 3],
borderWidth: 1,
pointRadius: (ctx) => (ctx.index % 2 === 0 ? 3 : 0),
backgroundColor: (ctx) => {
if (ctx.parsed === undefined) return;
return ctx.parsed.y > 16 ? 'orange' : ctx.parsed.y > 12 ? 'green' : ctx.parsed.y > 8 ? 'purple' : ctx.parsed.y > 4 ? 'blue' : 'black'
},
segment: {
borderColor: ctx => (ctx.p1.parsed.y > 16 ? 'orange' : ctx.p1.parsed.y > 12 ? 'green' : ctx.p1.parsed.y > 8 ? 'purple' : ctx.p1.parsed.y > 4 ? 'blue' : 'black')
}
}]
},
options: {
scales: {
yAxes: [{
ticks: {
reverse: false
}
}]
}
}
}
var ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);

I have a bar chart in vue-charts where when clicked I want to display the background data in a table. This is the render
startPie: function(canvas, type){
let chart = new Chart(canvas, {
type: type,
data: {
labels: this.labels,
datasets: this.chart_data
},
options: {
responsive: true,
animation:{ animateScale:true },
title: { display: false },
legend: { display: false },
scales: {
yAxes: [{
gridLines: {
color: "#989898"
},
ticks: {
fontColor: "#989898",
fontSize: 16,
beginAtZero: true,
callback: function(value) {
let ranges = [
{ divider: 1e6, suffix: 'M' },
{ divider: 1e3, suffix: 'k' }
];
function formatNumber(n) {
for (let i = 0; i < ranges.length; i++) {
if (n >= ranges[i].divider) {
return (n / ranges[i].divider).toString() + ranges[i].suffix;
}
}
return n;
}
return '$' + formatNumber(value);
}
}
}],
xAxes: [{
ticks: {
fontColor: "#989898",
fontSize: 12
}
}]
},

},
formatter: function(value, context) {
return '$' + Number(value).toLocaleString();
},
color: 'white'
}
},
'onClick':(evt, item) => {
console.log('CLICK', item[0]);
}
}
})
}
In the onClick Event in the console I can see the index
CLICK ChartElement {_chart: Chart, _datasetIndex: 0, _index: 4,
hidden: false, _xScale: ChartElement, …}
I can't access it though without an error. I have tried
item[0]._index, item[0]['_index'], item[0]['ChartElement']._index, item[0]['ChartElement']['_index']
Any help is appreciated.
Unfortunately, the onClick event handler is poorly documented. You could try to define the data in a separate variable outside of the chart configuration.
const data = [55, 68, 82, 48, 75, 45, 67];
Then, you can define the onClick event handler as follows:
options: {
...
onClick: (event, item) => {
const idx = chart.getElementAtEvent(event)[0]._index;
console.log(data[idx]);
}
}
const labels = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul"];
const data = [55, 68, 82, 48, 75, 45, 67];
let chart = new Chart(document.getElementById('myChart'), {
type: 'bar',
data: {
labels: labels,
datasets: [{
label: "My First Dataset",
data: data,
backgroundColor: ["rgba(255, 99, 132, 0.2)", "rgba(255, 159, 64, 0.2)", "rgba(255, 205, 86, 0.2)", "rgba(75, 192, 192, 0.2)", "rgba(54, 162, 235, 0.2)", "rgba(153, 102, 255, 0.2)", "rgba(201, 203, 207, 0.2)"],
borderColor: ["rgb(255, 99, 132)", "rgb(255, 159, 64)", "rgb(255, 205, 86)", "rgb(75, 192, 192)", "rgb(54, 162, 235)", "rgb(153, 102, 255)", "rgb(201, 203, 207)"],
borderWidth: 1
}]
},
options: {
responsive: true,
title: {
display: false
},
legend: {
display: false
},
scales: {
yAxes: [{

I want to develop an echart that has the area between 2 linecharts highlighted in a color. To achieve this, I made use of stacked area chart. I set the color of the upper area as the highlight color and color of lower area as white so as to achieve my result. However, the color of bigger area is merging with the lower area and producing a diff color. How can I set the colors of 2 areas to not interfere? Is there a way to give z-index to the areas for this?
Here is my code:
option = {
title: {
text: '堆叠区域图'
},
tooltip : {
trigger: 'axis',
axisPointer: {
type: 'cross',
}
},
legend: {
data:['邮件营销','联盟广告','视频广告','直接访问','搜索引擎']
},
toolbox: {
feature: {
saveAsImage: {}
}
},
grid: {
left: '3%',
right: '4%',
bottom: '3%',
containLabel: true
},
xAxis : [
{
type : 'category',
boundaryGap : false,
data : ['周一','周二','周三','周四','周五','周六','周日']
}
],
yAxis : [
{
type : 'value'
}
],
series : [
{
name:'联盟广告',
type:'line',
smooth: true,
areaStyle: {color: 'red'},
data:[170, 182, 161, 184, 160, 180, 165]
},
{
name:'邮件营销',
type:'line',
smooth: true,
areaStyle: {color: 'white'},
data:[120, 132, 111, 134, 110, 130, 115]
}
]
};
What I have achieved:
You need to increase the opacity of the below chart:
option = {
xAxis: {
type: 'category',
boundaryGap: false,
data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
},
yAxis: {
type: 'value'
},
series: [
{
z: -1, // optional, makes the yAxis' splitLines appear on top
data: [170, 182, 161, 184, 160, 180, 165],
smooth: true,
type: 'line',
areaStyle: {}
},
{
z: -1, // optional, makes the yAxis' splitLines appear on top
data: [120, 132, 111, 134, 110, 130, 115],
smooth: true,
type: 'line',
areaStyle: {
color: 'rgb(243, 243, 243)', // color of the background
opacity: 1, // <--- solution
},
}
]
};
The above answer only works if the series do not cross the X axis. Here is the configuration that works if your data is both above and below 0 for both upper and lower boundaries:
data = [{
"date": "2012-08-28",
"l": -2.6017329022,
"u": 0.2949717757
},
{
"date": "2012-08-29",
"l": 0.1166963635,
"u": 0.4324086347
},
{
"date": "2012-08-30",
"l": -0.8712221305,
"u": 0.0956413566
},
{
"date": "2012-08-31",
"l": -0.6541832008,
"u": 0.0717120241
},
{
"date": "2012-09-01",
"l": -1.5222677907,
"u": -0.2594188803
},
{
"date": "2012-09-02",
"l": -1.4434280535,
"u": 0.0419213465
},
{
"date": "2012-09-03",
"l": -0.3543957712,
"u": 0.0623761171
}];
myChart.setOption(option = {
xAxis: {
type: 'category',
data: data.map(function (item) {
return item.date;
})
},
yAxis: {
},
series: [
{
z: -1,
name: 'U',
type: 'line',
data: data.map(function (item) {
return item.u;
}),
lineStyle: {
opacity: 0
},
areaStyle: {
color: '#ccc',
origin: "start"
},
symbol: 'none'
},
{
name: 'L',
type: 'line',
data: data.map(function (item) {
return item.l;
}),
lineStyle: {
opacity: 0
},
z: -1,
areaStyle: {
color: "white",
origin: "start",
// opacity: 1
},
symbol: 'none'
}]
});
Create a third series with the difference between the minimum and maximum values. This data series is used only to be able to color the area between minimum and maximum values.
The stackStrategy option works from version v5.3.3
let max = [10, 22, 28, 20, 23];
let min = [8, 15, 23, 18, 19];
let dif = max.map((v, i) => min[i] - v); // [-2, -7, -5, -2, -4]
option = {
xAxis: {
data: ['A', 'B', 'C', 'D', 'E']
},
yAxis: {},
tooltip: {
trigger: 'axis',
},
series: [
{
data: max,
type: 'line',
stack: 'x', // stack name
},
{
data: dif,
type: 'line',
stack: 'x', // stack name
stackStrategy: 'positive', // strategy
lineStyle: {
opacity: 0 // hide line
},
symbol: 'none', // hide symbol
areaStyle: {
color: '#ccc'
},
tooltip: {
show: false // hide value on tooltip
}
},
{
data: min,
type: 'line',
},
]

I am selecting the first column, and i don't click it, just with the mouse over it. The higlight color is a variante of blue. But in the code i use itemmousedown, and i don't understand why the bar changed color only by passing by the mouse? how can i put it only highlight only in mouse click?
What about highlight: false?
If you just want the bar to be highlighted by a click, you should add a listener which highlights it on clicking the bar.
