How to change the scale of an axis with HighChart

I'm using HighChart to display the memory usage of some containers. The problem is that sometimes the scale is in K sometimes in M and sometimes with nothing (like the picture bellow):
And this is how I create my HighChart:
var cursor = Template.currentData();
liveChart = Highcharts.chart(cursor.chart_id, {
title: {
text: 'Memory usage of the controlcontainers_mongo_1'
},
xAxis: {
type: 'datetime',
},
yAxis: {
title: {
text: 'usage'
}
},
tooltip: {
formatter: function() {
return '<b>' + this.series.name + '</b><br/>' + Highcharts.dateFormat('%Y-%m-%d %H:%M:%S', this.x) + '<br/>';
}
},
series: [{
type: 'line',
name: 'memory usage',
data: []
}]
});
[EDIT] Maybe it could be helpful to see the entire graph so there is it:
This is my formatter if someone need it:
formatter: function() {
var usage = this.value;
if((usage >= 1000000)&&(usage < 1000000000)){
return (usage/1000000).toFixed(2) + "MB";
}else if (usage >= 1000000000) {
return (usage/1000000000).toFixed(2) + "GB";
}else{
return usage + "KB";
}
}

You can round up the values in y-axis formatting function
var cursor = Template.currentData();
liveChart = Highcharts.chart(cursor.chart_id, {
title: {
text: 'Memory usage of the controlcontainers_mongo_1'
},
xAxis: {
type: 'datetime',
},
yAxis: {
title: {
text: 'usage'
},
labels: {
formatter: function() {
//This will round the value, but you can do anything to this value now
return this.value.toFixed(2);
}
},
},
tooltip: {
formatter: function() {
return '<b>' + this.series.name + '</b><br/>' + Highcharts.dateFormat('%Y-%m-%d %H:%M:%S', this.x) + '<br/>';
}
},
series: [{
type: 'line',
name: 'memory usage',
data: []
}]
});

Only one function in highcharts will function

I'm trying to manipulate a chart with input boxes. Each input box should correspond to a bar. In my code, I can get the first function at the bottom of the highcharts to work, but identical code with the bar changed and the input id doesnt work. Function in question is the last function with season-2 as id.
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
animation: false
},
xAxis: {
categories: ['2016-17', '2017-18', '2018-19', '2019-20', '2020-21', '2021-22'],

text: 'Season'
}
},

title: {
text: '$ Dollars'
}
}],

series: {
borderColor: '#2c3e50',
point: {
events: {
drag: function(e) {
$('#drag').html(
'Dragging <b>' + this.series.name + '</b>, <b>' + this.category + '</b> to <b>' + Highcharts.numberFormat(e.y, 2) + '</b>');
if (this.category == "2016-17"){
$('#season-1').val(Highcharts.numberFormat(e.y, 2));
}
if (this.category == "2017-18"){
$('#season-2').val(Highcharts.numberFormat(e.y, 2));
}
if (this.category == "2018-19")
{
$('#season-3').val(Highcharts.numberFormat(e.y, 2));
}
if (this.category == "2019-20"){
$('#season-4').val(Highcharts.numberFormat(e.y, 2));
} if (this.category == "2020-21"){
$('#season-5').val(Highcharts.numberFormat(e.y, 2));
}
},
drop: function() {
$('#drop').html(
'In <b>' + this.series.name + '</b>, <b>' + this.category + '</b> was set to <b>' + Highcharts.numberFormat(this.y, 2) + '</b>');
}

dragMinY: 0,

}]
}, function(chart) {
$('#season-1').change(function() {
var val = parseInt(this.value) || 0;
chart.series[3].data[0].update({
y: val
});
})
},
function(chart) {
$('#season-2').change(function() {
var val = parseInt(this.value) || 0;
chart.series[3].data[1].update({
y: val
});
})
});
http://jsfiddle.net/twq6gb7d/

What I did is I isolated the change functions from inside the highcharts initialization function, and let JQuery handle it by selecting the container of the chart and calling the highchart function.
Snippet of the code:
.... //rest of the code
dragMinY: 0,
type: 'column',
minPointLength: 2,
color: '#2c3e50'
}]
}); //end of the highchart initialization
$('#season-1').change(function() {
var val = parseInt(this.value) || 0;
$('#container').highcharts().series[3].data[0].update({
y: val
});
});
... // other change functions

how to change the default animation from right to left for series in highcharts?

How to change the default animation from right to left for series in high charts as animation:false will remove animation and by default whenever chart loads its from left to right but i want it from right to left..
I am adding the link in addition to that which captures live data and then it is displayed in high charts.

Why isn't the xAxis showing the date?

I have a question related to HighCharts. Below is my code for implementing a highchart with integer values on yaxis and date on x-axis. I am getting my data from database both date and values.
The x-axis date and time isn't displayed correctly. In my database it looks like that ,2015-04-27 15:26:41.463 .
var a = [];
$('#container').highcharts({
chart: {
type: 'spline',
animation: Highcharts.svg, // don't animate in old IE
marginRight: 10,
events: {
load: function () {
// set up the updating of the chart each second
var series = this.series[0];
xAxis[0].setCategories(x);
}
}
},
title: {
text: 'Live random data'
},
xAxis: {
categories: a
},
yAxis: {
title: {
text: 'Value'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
formatter: function () {
return '<b>' + this.series.name + '</b><br/>' + Highcharts.dateFormat('%Y-%m-%d %H:%M:%S', this.x) + '<br/>' + Highcharts.numberFormat(this.y, 1);

This is what I have reached now
.success(function (point) {
for (i = 0; i < point.length; i++) {
myDate[i] = point[i].date_time;
value[i] = point[i].value_db;
}
for (j = 0; j < myDate.length; j++) {
var temp = new Array(myDate[j], value[j]);
mySeries[j] = temp;
}
DrawChart(mySeries, myDate, value);

UPDATE2
Help Please.

You'll have to change myDate[i] = point[i].date_time; to:
myDate[i] = parseInt((point[i].date_time).substring(6, 19));
So that it will contain the UTC date format of the datetime.
Then you will have to use xAxis.labels.formatter like this:
xAxis: {
labels: {
formatter: function() {
var date = new Date(this.value);
return date.getFullYear() + "-" +
date.getMonth() + "-" +
date.getDate() + " " +
date.getHours() + ":" +
date.getMinutes() + ":" +
date.getSeconds();
}
}
}
to tell the chart how to show it's xAxis labels.
And for showing more labels in yAxis, you can use:
yAxis: {
tickInterval: 100 // if you want the labels to show every 100 values
}

do not remove previous point in spline highchart

in splin highchart when draw new live point,it remove first point from left.
how can i disable this work in highchart
my chart must be in fix datetime range,and live splin chart must begin in min datetime and finish in max datetime.and do not remove any point.
when recieve to max datetime the point must be clear.
$(function () {
$(document).ready(function () {

Check your condition to remove from left or not, if you need to remove call :
series1.addPoint([x, y], true, true);
else call:
series1.addPoint([x, y], true, false);
