Stuck on the final bits of a multi series line chart

I built a multi series Highcharts https://www.highcharts.com/ line chart with irregular time data. It's almost there, but I'm doing something wrong with the data and/or data formatting. Anyone have a hint or two to throw my way?
The date from the database was converted from '02/03/2009' to javascript time in php using
$date = strtotime($data['As of Date'])*1000;
The other value is a dollar amount.
I haven't yet added the filtered data for 3MO, 6MO, 1YR, 5YR, 10YR
Here is the jsfiddle https://jsfiddle.net/madmichael/th41g4yt/
$( document ).ready(function() {
createChart();
});
function createChart(chartingOptions) {
var options = {
chart: {

var total = 0; // get total of data
for (var i = 0, len = this.series[0].yData.length; i < len; i++) {
total += this.series[0].yData[i];
}
var text = this.renderer.text(
'Total: $' + Highcharts.numberFormat(total, 0, '.', ','),
this.plotLeft,
this.plotTop + 20
).attr({
zIndex: 5
}).add() // write it to the upper left hand corner

Highcharts how to make the y axis series value return only 2 decimal places

I want to make the format of my y axis series to only return 2 decimal places.
I have this code:
$('#main-graph').highcharts({

},
xAxis: {

yAxis: [

}
},
{ //3
title:{

}
},
{ //4
title:{
text: "CPC"
}
},
{ //5 - secondary axis which is the SPEND axis
title: {

}
},

},

data: clicks,
yAxis: 1
},
{

yAxis: 2
}, {
name: 'CPM',
data: cpm,
yAxis: 3
}, {
name: 'CPC',
data: cpc,
yAxis: 4
}
]
});
}
I tried adding this line of code:
dataLabels: {
enabled: true,
formatter: function () {
return Highcharts.numberFormat(this.y,2);
}
}
but it isn't working.
Any ideas? your help will be grealty apprecaited!
Thanks!

Disabling label without bar Highstock

I have a column chart Highstock:
http://jsfiddle.net/txfnsubb/
When we change range to smaller values, sometimes it shows us a label of value w/o the bar. For example I see 30 bars and at the end label with 31. Is there a possibility to turn it off? To set chart to showing label only with bar.

Plot always starts at 0, highstock spline chart

I have data like this
var data = [];
for(var i=1;i<201;i++){
data.push([i,(Math.random() * (80 - 40 + 1)) + 40])
}
And I'm creating chart like this:
$('.reactivityCont').highcharts('StockChart', {

},
credits: {

rangeSelector : {
selected : 1

return this.value;
}
},

start = parseInt(e.min);
koniec = parseInt(e.max);
$('.nt').hide();
for(var i = start-1;i<koniec;i++){
$('.nt').eq(i).show();
}
main();
}
}
},
series : [{
type: 'column',
name : 'reactivity',

}
},
{type: 'spline',
name: 'experiment 1',
data: data2,
color: 'green',

}
},
{type: 'spline',
name: 'experiment 2',
data: data3,
color: 'red',
visible: false,
tooltip: {
valueDecimals: 2
}
}
],
legend :{
enabled: true,
margin: 0
},
rangeSelector : {
buttons: [
{
type: 'millisecond',
count: seqLength/5,
text: '0.25'
}, {
type: 'millisecond',
count: seqLength/3,
text: '0.3'
}, {
type: 'millisecond',
count: seqLength/2,
text: '0.5'
}, {
type: 'all',
text: '1.0'
}
],
inputEnabled: false, // it supports only days
selected : 4 // all
}
});
But unfortunately, my plot starts with 0, but it should not, because there is no such a value.
I tried fix it, e. g. by setting plotOptions:pointStart but that didn't work.

This is caused by using column type series, where columns always starts from 0. To prevent this set threshold: null, like this:
series : [{
type: 'column',
threshold: null,
...
}]

You can use theXAxis's min param.
For Example.
xAxis: {
labels: {
formatter: function() {
return this.value;
}
},
min: myInitValue,
max: myEndValue
}
Hope It Helps.

Hide Numbers when category is null

Kindly take a look at following fiddle in which i tried to remove the categories but on removing categories its placing numbers instead of it by default and also showing those numbers in tooltip.
All I am trying to do is that categories or numbers doesnot display on chart or on tooltip and only stackedbar appears on the chart , So kindly let me know how can i do it .Thanks,

I'm not 100% sure of what you are asking for. But, to turn off the XAxis or yAxis labels, juse labels : {enabled:false} and to change the tooltips use tooltip:{formatter: function() {...}}
see this fiddle:
http://jsfiddle.net/6ypq4/
xAxis: {
title: {
text: null
},
labels : {
enabled: false
}
},
yAxis: {
min: 0,
title: {
text: 'Population (millions)',
align: 'high'
},
labels: {
overflow: 'justify',
enabled: false
}
},
tooltip: {
formatter: function() {
return this.y + ' millions';
}
},
