show two different stacked column data in one chart canvasjs react

I want two stacked column data in one chart using canvasjs like this:
I have currently done something like this with the options:
this achieves removing x axis and secondary y axis and showing two data together
{
animationEnabled: true,
options:{
scales: {
xAxes: [{ stacked:true}]
}
},
axisY: {
titleFontColor: "#4F81BC",
lineColor: "#4F81BC",
labelFontColor: "#4F81BC",
tickColor: "#4F81BC",
margin:24,
},
axisY2: {
gridThickness: 0,
tickLength: 0,
lineThickness: 0,
margin:24,
labelFormatter: function(){
return " ";
}
},
axisX:{
gridThickness: 0,
tickLength: 0,
lineThickness: 0,
margin:24,
labelFormatter: function(){
return " ";
}
},
toolTip: {
shared: true
},
legend: {
cursor:"pointer",
},
data: [{
type: "stackedColumn",
name: "Proven Oil Reserves (bn)",
legendText: "Proven Oil Reserves",
showInLegend: false,
dataPoints:[
{ y: 30.25 },
]
},
{
type: "stackedColumn",
name: "Oil Production (million/day)",
legendText: "Oil Production",
showInLegend: false,
dataPoints:[
{ y: 17.46 },
]
},
{
type: "stackedColumn",
name: "Oil Production (million/day)",
legendText: "Oil Production",
axisYType:"secondary",
margin:10,
showInLegend: false,
dataPoints:[
{ y: 10.46 },
]
},
{
type: "stackedColumn",
name: "Oil Production (million/day)",
legendText: "Oil Production",
axisYType:"secondary",
margin:10,
showInLegend: false,
dataPoints:[
{ y: 10.46 },
]
}
]
}
it produces the result like:
what I need is to
give margin between two datasets
able to label datasets with text over them as seen in the image above

give margin between two datasets
There will be gap between datapoints when the x-values are different.
able to label datasets with text over them as seen in the image above
You can use indexlabels. Please refer CanvasJS Docs for more info / examples. Below is an working example.
var chart = new CanvasJS.Chart("chartContainer", {
animationEnabled: true,
axisX:{
gridThickness: 0,
tickLength: 0,
lineThickness: 0,
labelFormatter: function(){
return "";
}
},
axisY: {
includeZero: true,
tickLength: 0,
lineThickness: 0,
gridColor: "#ddd",
labelFormatter: function(e) {
return "";
}
},
toolTip: {
shared: true
},
data: [{
type: "stackedColumn",
indexLabel: "RM xyz",
indexLabelFontColor: "#fff",
dataPoints: [
{ x: 1, y: 47, color: "#c63531" },
{ x: 2, y: 32, color: "#449fc7" }
]
}, {
type: "stackedColumn",
indexLabel: "RM xyz",
indexLabelFontColor: "#fff",
dataPoints:[
{ x: 1, y: 32, color: "#bb8786" },
{ x: 2, y: 27, color: "#74ab3e" }
]
}]
});
chart.render();
<script src="https://canvasjs.com/assets/script/canvasjs.min.js"></script>
<div id="chartContainer" style="height: 300px; width: 100%;"></div>

how to add new value in the tooltip?

I want to add a new value in the tooltip, but I don't want to show the value in the chart. I searched but i did not find any solution. for example:
{
show: false,
name: '利润',
type: 'bar',
label: {
show: true,
position: 'inside'
},
data: [20, 17, 24, 24]
},
{
name: '收入',
type: 'bar',
stack: '总量',
label: {
show: true
},
data: [320, 302, 341, 374]
},
{
name: '支出',
type: 'bar',
stack: '总量',
label: {
show: true,
position: 'left'
},
data: [120, 132, 101, 134]
}
can i add show:false or different things?
my echarts version is ^3.8.5.

Actually this can be done by reformatting your series data and customize tooltip formatter function. You can take a look at this case and make your own adjustment.
For example, data with higher dimension can be added like this:
data: [
['Mon', 120, 0],
['Tue', 200, 1],
['Wed', 150, 2],
['Thu', 80, 3],
['Fri', 70, 4],
['Sat', 110, 5],
['Sun', 130, 6],
],
Data with dimension index 0 and 1 will be plotted in the series, but dimension 2 will not shown.
Then make custom tooltip formatter function. For example:
formatter: function(params) {
return `
${params.seriesName}:<br />
Day: ${params.value[0]}<br />
Value: ${params.value[1]}<br />
New Value: ${params.value[2]}<br />
`
}
Complete example:
option = {
xAxis: {
type: 'category',
},
yAxis: {
type: 'value'
},
tooltip: {
trigger: 'item',
formatter: function(params) {
return `
${params.seriesName}:<br />
Day: ${params.value[0]}<br />
Value: ${params.value[1]}<br />
New Value: ${params.value[2]}<br />
`
}
},
series: [{
data: [
['Mon', 120, 0],
['Tue', 200, 1],
['Wed', 150, 2],
['Thu', 80, 3],
['Fri', 70, 4],
['Sat', 110, 5],
['Sun', 130, 6],
],
name: 'MySeries',
type: 'bar'
}]
};
Result:
See on Imgur

maybe custom series it worked but i couldn't find examples about bar chart. there is an example in the site but the example is about gantt chart.

You cannot find this one or similar settings because they should not exist. It's breaking the main dataviz concept: visualization should simplify rather than complicate the perception of data. You cannot to hide the same data for one place and show it in the another in common context. User don't understand what is the reason of this inconsistence and will stop to trusting your chart.
But if you insist, then make the desired like this:
legend: {
data: [{
name: '直接访问',
textStyle: {
color: 'red'
}
},
{
name: '邮件营销',
textStyle: {
color: 'green'
}
}
// [...]
]
}
and for hidden series:
series: [
{
name: '直接访问',
type: 'bar',
data: [0, 0, 0, 0, 0, 0, 0],
},
// {...}
]
var myChart = echarts.init(document.getElementById('main'));
var option = {
tooltip: {
trigger: 'axis',
axisPointer: {
type: 'shadow'
}
},
legend: {
data: [{
name: '直接访问',
textStyle: {
color: 'red'
}
},
{
name: '邮件营销',
textStyle: {
color: 'green'
}
}
// [...]
],
},
grid: {
left: '3%',
right: '4%',
bottom: '3%',
containLabel: true
},
xAxis: {
type: 'value'
},
yAxis: {
type: 'category',
data: ['周一', '周二', '周三', '周四', '周五', '周六', '周日']
},
series: [{
name: '直接访问',
type: 'bar',
data: [0, 0, 0, 0, 0, 0, 0],
},
{
name: '邮件营销',
type: 'bar',
stack: '总量',
data: [120, 132, 101, 134, 90, 230, 210]
},
{
name: '联盟广告',
type: 'bar',
stack: '总量',
data: [220, 182, 191, 234, 290, 330, 310]
},
{
name: '视频广告',
type: 'bar',
stack: '总量',
data: [150, 212, 201, 154, 190, 330, 410]
},
{
name: '搜索引擎',
type: 'bar',
stack: '总量',
data: [820, 832, 901, 934, 1290, 1330, 1320]
}
]
};

Apexchart leaves wrapper when I insert two Y-Axes

If I add two Y-Axes to an Apexchart it is pushed beyond the wrapper and does not resize properly.
I would like to have one Y-Axis displayed on the left side of the chart and the other one on the right side of the chart.
I tried to debug it in my dev tools but I am sure that this is a canvas problem itself.
I provided the snippet below which shows how the left Y-Axis and Jan data are out of scope.
var yearMapOptions = {

var yearMapChart = new ApexCharts(

yearMapChart.render();

Removing grid: { show: false } makes the y-axis visible.
PS: Changing grid behavior should not affect the y-axis. It seems like a bug in ApexCharts which will be addressed soon.

Echarts, how to use visualMap

How to use the visualMap to color lines based on their value on the X-axis. I want to color red for all values greater than 23 and green for all values greater than 23.
My script looks like the following:
<html>
<head>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/echarts/4.1.0/echarts.min.js"></script>
</head>
<body>
<div id="main_chart" style="width: 1200px;height:600px;"></div>
<script type="text/javascript">
// based on prepared DOM, initialize echarts instance
var myChart = echarts.init(document.getElementById('main_chart'));
var app = {};
option = null;
option = {
xAxis: {
type: 'category',
data: ['2012-03-01 05:06', '2012-03-01 05:07', '2012-03-01 05:08', '2012-03-01 05:09', '2012-03-01 05:10', '2012-03-01 05:11']
},
yAxis: {
type: 'value'
},
visualmap: {
show: false,
dimension: 0,
min: 0,
max: 10,
range: [0, 23],
inRange: {
color: 'red'
},
outOfRange: {
color: 'green'
}
},
series: [{
data: [20, 22, 25, 27, 30, 25],
type: 'line',
areaStyle: {}
}]
};
;
if (option && typeof option === "object") {
myChart.setOption(option, true);
}
</script>
</body>
</html
Unfortunately this doesn't work like this.
In general, there is a good description somewhere how this works with the visualMap, in the official documentary of echarts I don't get it.

I assume you want to color red for all values less than 23 and green for all values greater than 23.
you can use visualMap like this
"visualMap": [{
"pieces": [{
"gte": 23,
"label": ">= 23",
"color": "green"
}, {
"lt": 23,
"gt": 0,
"label": "< 23",
"color": "red"
}],
}],
let echartsObj = echarts.init(document.querySelector('#canvas'));
let seriesData = [1, 1, 2, 3, 4, 6, 8];
option = {
xAxis: {
type: 'category',
data: ['2012-03-01 05:06', '2012-03-01 05:07', '2012-03-01 05:08', '2012-03-01 05:09', '2012-03-01 05:10', '2012-03-01 05:11']
},
yAxis: {
type: 'value'
},
series: [{
data: [20, 22, 25, 27, 30, 25],
type: 'line',
areaStyle: {}
}],
"visualMap": [{
"pieces": [{
"gte": 23,
"label": ">= 23",
"color": "green"
}, {
"lt": 23,
"gt": 0,
"label": "< 23",
"color": "red"
}],
}],
};
echartsObj.setOption(option)
<html>
<header>
<script src="https://cdn.bootcss.com/echarts/4.1.0.rc2/echarts-en.min.js"></script>
</header>
<body>

Combination of Scatter HighChart with Polynomial Chart

I am trying a chart that combines two chart types in a one single-chart (spline & polynomial). When I merge both of them the chart stops working. If I them separately they work. Can I merge both chart in one using highchart?

That's a reported bug. Anyway while using a transparent color for the spline it works :
series: [{
regression: true,
regressionSettings: {
type: 'polynomial',
color: 'rgba(223, 183, 83, 0)', // transparent color
dashStyle: 'dash'
},
name: 'SplineChart',

marker: {

},
data: [
[1, 2],
[1, 6],
[3, 9],
]
}
