How I can have multiple y-axis?

[coderrrr]

I want the data2 on second y axis data1 on first. And How I can have months name as x-axis titles?
`window.onload = function () {
var data = [];
var data2 = [];
var chartData = [
{
“January”:”1″,
“February”:”2″,
“March”:”3″,
“April”:”4″,
“May”:”5″,
“June”:”6″,
“July”:”7″,
“August”:”8″,
“September”:”9″,
“October”:”10″,
“November”:”11″,
“December”:”12″
},
{
“January”:”12″,
“February”:11″,
“March”:”10″,
“April”:”9″,
“May”:”8″,
“June”:”7″,
“July”:”6″,
“August”:”5″,
“September”:”4″,
“October”:”3″,
“November”:”2″,
“December”:”1″
}
]

for( var i=0; i<chartData.length; i++) {
var dataPoints = [];
for (var obj in chartData[i]) {
if(i == 0){
if (chartData[i].hasOwnProperty(obj)) {
dataPoints.push({x : chartData[obj], y: Number(chartData[i][obj])});
}
data.push({
type: “line”,
dataPoints: dataPoints
})
}
else
{
if (chartData[i].hasOwnProperty(obj)) {
dataPoints.push({x : chartData[obj], y: Number(chartData[i][obj])});
}
data2.push({
type: “line”,
dataPoints: dataPoints
})
}
}
}
var chart= new CanvasJS.Chart(“chartContainer”, {
title:{
text: “Multiple y – axis”
},
axisY2: {
},
axisY: {
},
data:data
});
chart.render();

@dhami97,

You can use label property to show labels over axisX and setting axisYType to secondary will attach dataSeries to secondary y-axis. Please take a look at this JSFiddle for a working example with your set of dataPoints.

thanks you so much @Vishwas R, Could you please tell me how i can include legend for this chart?

[Vishwas R]

@dhami97,

By setting showInLegend property to true, you can show legend to a dataSeries. Please refer to the documentation page on legend for more information and more customization options available.

Hey Thanks. The data series legend is visible now but not sure where to put the legendText.

@dhami97,

legendText is a property of dataSeries that’s used to set the text to be displayed in the legend for a particular dataSeries. Please refer documentation for more information along with live example.
