why x-axis showing alternate months rather every month? - highcharts

Question

Following is my highcharts config, can you help me to why my alternate months are coming, and if i want to show every month, how do i do it ? Also, to change width of the bar if showing every month.
Highcharts.chart("energy_chart", {
chart: {
type: "column",
spacingBottom: 15,
spacingTop: 10,
spacingLeft: 10,
spacingRight: 10,
backgroundColor: "#f2f2f2",
events: {
load: function() {
var fin = new Date();
var finDate = fin.getDate();
var finMonth = fin.getMonth();
var finYear = fin.getFullYear();
var ini = new Date();
ini.setFullYear(ini.getFullYear() - 1);
var iniDate = ini.getDate();
var iniMonth = ini.getMonth();
var iniYear = ini.getFullYear();
if (this.yAxis[0].dataMax == 0) {
this.yAxis[0].setExtremes(null, 1);
}
//this.yAxis.set
console.log(new Date(Date.UTC(iniYear, iniMonth, iniDate)))
console.log(new Date(Date.UTC(finYear, finMonth, finDate)))
this.xAxis[0].setExtremes(
Date.UTC(iniYear, iniMonth, iniDate),
Date.UTC(finYear, finMonth, finDate)
);
},
drilldown: function(e) {
console.log('drilldown')
var charts_this = this;
var inidrillDate = new Date(e.point.x);
setTimeout(function() {
inidrillDate.setDate(0);
inidrillDate.setMonth(inidrillDate.getMonth());
var DateinidrillDate = inidrillDate.getDate();
var MonthinidrillDate = inidrillDate.getMonth();
var YearinidrillDate = inidrillDate.getFullYear();
var findrillDate = inidrillDate;
findrillDate.setMonth(findrillDate.getMonth() + 1);
findrillDate.setDate(findrillDate.getDate() - 1);
var DatefindrillDate = findrillDate.getDate();
var MonthfindrillDate = findrillDate.getMonth();
var YearfindrillDate = findrillDate.getFullYear();
console.log(Date.UTC(
YearinidrillDate,
MonthinidrillDate,
DateinidrillDate
))
console.log(Date.UTC(
YearfindrillDate,
MonthfindrillDate,
DatefindrillDate
))
charts_this.xAxis[0].setExtremes(
Date.UTC(
YearinidrillDate,
MonthinidrillDate,
DateinidrillDate
),
Date.UTC(
YearfindrillDate,
MonthfindrillDate,
DatefindrillDate
)
);
if (charts_this.yAxis[0].dataMax === 0) {
charts_this.yAxis[0].setExtremes(null, 1);
}
}, 0);
}
}
},
title: {
text: '<p className="energy_gen">Energy Generated</p>'
},
exporting: { enabled: false },
xAxis: {
type: "datetime",
labels: {
step: 1
},
dateTimeLabelFormats: {
day: "%e"
}
},
yAxis: {
title: {
text: "kWh"
}
},
credits: {
enabled: false
},
plotOptions: {
series: {
cursor: "pointer",
dataLabels: {
enabled: true,
format: "{point.y}"
},
color: "#fcd562",
point:{
events:{
click:function(event){
}
}
}
}
}
},
tooltip: {
formatter: function() {
if (this.point.options.drilldown) {
return (
"Energy generated: <b> " +
this.y +
"</b> kWh " +
"<br>" +
Highcharts.dateFormat("%b %Y", new Date(this.x))
);
} else {
return (
"Energy generated: <b> " +
this.y +
"</b> kWh " +
"<br>" +
Highcharts.dateFormat("%e %b %Y", new Date(this.x))
);
}
}
},
series: [{'data':obj.data,'name':obj.name,"color":"#4848d3"}],
drilldown: {
series: obj.data
}
});
Also, attaching the screenshot of the rendered highchart with drilldown.
,
Now drilldown graph(same sort a issue)
EDIT:
It turnsout to be a zoom issue, i.e if i zoomout enough, then it shows all points. So, how to show every point without zooimg out .

Use tickInterval property and set it to one month:
xAxis: {
type: "datetime",
tickInterval: 30 * 24 * 3600 * 1000,
labels: {
step: 1
},
dateTimeLabelFormats: {
day: "%e"
}
}
