Highcharts doesn't plot series with lots of data - javascript

I trying to get highcharts to draw a linked graph. It works when I have not so much data in my data set. Now I have tried to put a dataset with ~30.000 points. I see the mouse over with the points, but the line is not plot?
I have read about turboThreshold: and have set it to turboThreshold: 40000 but it does still not plot the line??
Any ideas what I do wrong?

HighCharts add space to Y-Axis Label gutter

I have created a chart using the HighCharts javascript library, the problem I have is that my y-Axis labels are cut by the Y-Axis vertical line. I would like to add more space in the y-axis label gutter area to allow for the labels to be fully visible and so i can add some annotations to the in that area, see image below:
Ideally I would like to add 40px, to the Y-Axis gutter. I have read through the api reference and tried using "yAxis.labels.padding", "yAxis.margin" and "yAxis.offset".
My code is as follows:
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title></title>
<style type="text/css">

Been banging my head around this for while, but I cant seem to figure it out any help would be very much appreciated. Thanks
In Highstock, the yAxis is inverted by default, so aligning the labels is reversed as well.
The only thing you need to change is setting yAxis.labels.align to 'left'.

Dyanamic highchart with csv/txt input file

I am new on highchart. I have gone through the help portal of this and I am unable to fulfill my requirement so need you help/guide to complete this task .
My task is to read the data from a csv/TXT file which contains TPS details as per below format and show it on a dynamic running chart ( it's ok if the chart will refresh in one minute ) .
DATA format:
16:08:02,3
16:08:04,5
16:08:05,1
16:09:01,10
The above file is appending on every second , will read the last one minute data from file and plot this on chart .
I have tried this using below code. Don't know what I am missing.

You probably have incorrect paths to your script files.

Anyway, the most preferable way is to use getJson method:
$.getJSON( "test.json", function( data ) {
var items = [];
$.each( data, function( key, val ) {
... process data
});
...
});

Flot returns incorrect x value (mm/dd/yy - date) after zoom for stack bar chart

I want to get the correct x axis label when user zooms the chart and click on a specific bar
when clicking on the bar on (02/14/14 - xaxis) the alert shows the (02/19/14 - xaxis) label.
It returns the correct date when the zoom(selection) is not firing. but after zooming the chart and clicking on the bar it populate a wrong date.
I am new to flot charts. please help me. thanks.

The problem is this line of code:
var tickClicked = item.series.xaxis.ticks[item.dataIndex+1].label;
When your plot is unzoomed you have one tick per datapoint (bar). When you zoom, however, you end up with in between ticks, so the finding a tick by item.dataIndex isn't going to work.
I'm guessing you care more about the data associated to the bar (and not really the tick) so get the bar x value and format it back to a date string.
var tickClicked = $.plot.formatDate(new Date(item.datapoint[0]),"%m/%d/%Y");
EDITS
Instead of making another .plot call on zoom redraw the chart with (this is how I do it in my applications using flot):
var opts = plot.getOptions();
opts.xaxes[0].min = ranges.xaxis.from;
opts.xaxes[0].max = ranges.xaxis.to;
opts.yaxes[0].min = ranges.yaxis.from;
opts.yaxes[0].max = ranges.yaxis.to;
plot.setupGrid();
plot.draw();

HighCharts - Getting chart to display - Simple example (markit API)

I am new to programming with JavaScript and am having some troubles implementing a HighCharts chart. The API I am using is markit (https://github.com/markitondemand/DataApis/blob/master/MarkitTimeseriesServiceSample.js) to produce a chart as shown halfway down this page http://dev.markitondemand.com/
Now I thought I had to add that js script in place of the js shown in this fiddle (http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/line-basic/) but it doesn't seem to be working.
I think it may be because I am not assigning where I actually want to put it but I am not 100% sure.
Please see below for my code:

Thanks a lot for the help.
In your <div> change the id to #chartDemoContainer
Replace your jQuery libraries with these,
<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
And here's a working version of your example - http://jsbin.com/behicetivi/edit?html,output
