HighStocks/HighCharts scrollbar not displaying with large datasets causing xAxis labels to disappear and making bars not show

I'm creating a HighStock column bar chart. I have enabled the scrollbar using scrollbar: enabled. The scrollbar works fine for smaller datasets, but this dataset has a lot of categories(I've only included half as many as I need). For some reason, after a certain number, the rects for the bar chart won't properly show(or show wrong values) and the xAxis labels display as numbers rather than their actual names. Also, I'm trying to add IDs to each of the bars to add click events, but it only adds IDs to bars that are properly rendered initially. I have also noticed that I can properly add IDs even with a scrollbar to smaller data sets because all of the rect elements are properly rendered. Is there any way to make this scrollbar work for larger datasets?
You'll see what the problem described above looks like in this link:

}]
});

It happens because the number of points in series is bigger than the default value of the cropThreshold property (more about below, in the API Reference section). As a solution, set the property with the bigger value.

Different tooltips for series in FlotChart

I have Flot line chart with two dataseries. I would like to edit the tooltips independently for each series. I have tried moving the tooltip settings to the dataset part but it didn't work.
Does anyone know a solution?
$(function () {
var barOptions = {
xaxis: {
tickDecimals: 0
},
yaxes: [{
position: "left"
}, {
position: "right"
}],
colors: ["#36c6d3"],
grid: {
color: "#888888"
},
tooltip: {
show: true,
content: "Uge %x, %s: %y"
}
};
var dataset = [{
data: occData.data,
label: occData.label,
yaxis: occData.yaxis,
lines: {
show: true,
lineWidth: 1,
}
}, {
data: houseData.data,
label: houseData.label,
yaxis: houseData.yaxis,
color: 'grey',
lines: {
show: true,
lineWidth: 1,
fill: false
}
}];
$("#flot-line-chart-past").plot(dataset, barOptions);
});

I'm going to presume that you are using flot.tooltip to provide the tooltips. In which case, the content property of the tooltip configuration object can be a function as well as a format string. I quote from the documentation for the plug-in:
you can pass a callback function(label, xval, yval, flotItem) that must return a string with the format described.
So write a function that distinguishes between each label you use for the two series, and return a different format string for each.

Is it possible to disable navigator(small series) but remains the extensible scroll bar,Highstock

I need to remain the functionality of extensible scroll bar, but I don't need overview navigator. Like :
I need the scroll bar(area 1) to still remains extensible, but remove the navigator(area 2).
This is a design of what I want:
demo you could quickly modify from :
$(function () {
$.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=aapl-c.json&callback=?', function (data) {
// Create the chart
var chart = $('#container').highcharts('StockChart', {
rangeSelector : {
enabled: false
},
title: {
text: null
},
navigator: {
enabled:false,//make it false , but the scroll bar is not extensible
outlineWidth: 0
},
scrollbar: {
barBackgroundColor: '#ccc',
barBorderWidth: 0,
buttonBackgroundColor: '#ccc',
buttonBorderWidth: 0,
buttonArrowColor: '#fff',
buttonBorderRadius: 3,
rifleColor: '#fff',
trackBackgroundColor: 'white',
trackBorderWidth: 1,
trackBorderColor: '#ccc',
trackBorderRadius: 3
},
series: [{
type:'areaspline',
showInLegend: false,
name: 'AAPL1',
data: data
},{
type:'areaspline',
showInLegend: false,
name: 'AAPL2',
data: data.map(function(d){return [d[0],parseInt(d[1])*2 ]})
}]
});
});
});

Scrollbar can not be resized like Navigator, so I think what you really want to use is (2) Navigator and disable (1) Scrollbar. Here is simple example do to do: http://jsfiddle.net/dJbZT/183/
navigator: {
enabled:true,
outlineWidth: 0,
height: 14,
maskFill: '#cccccc',
series: {
data: [] // empty navigator
},
xAxis: {
labels: {
y: -20 // move labels outside the navigator
}
}
},
If the navigator should have background, you can add two dummy points for the series, one at the beginning of the original series and one on the end:
data: [
[data[0][0], 2],
[data[data.length - 1][0], 2]
]
Then just set color and fillOpacity for a series, to the color you want to achieve, and set yAxis.max below your dummy value (2 in my case). Working demo: http://jsfiddle.net/dJbZT/184/

Apply outer border for the highchart area chart

I am implementing the area chart as shown in the mock up, but have strict at some portion and not able to get option s that are available in http://api.highcharts.com/highcharts for configuring the chart to look as is.
Here is the mock up look.
What I have achieved so far is :
Fiddle Demo
So I could not able to achieve the
1.background color
backgroundColor: {
linearGradient: false,
stops: [
[0, 'rgb(255, 255, 255)'],
[1, 'rgb(200, 200, 255)']
]
},
2 . Only outer border line. (As shown in the mock up)
3 . On Hover Show All 3 labels. (As shown in the mock up)
4 . Legend like "CPM IMPS SPEND BY TIME" with colors I mean I want to acheive same as in mock up.
Last Point to implement :

Well..
1.background color:
chart: {
backgroundColor: 'black', //for whole plot
name: 'IMPS',
data: [
...
], color: 'rgb(213, 156, 72)' //for one area
2 . Only outer border line. (As shown in the mock up)
yAxis: [{
lineWidth: 1,
title: {
text: ''
},
labels: {
formatter: function () {
return this.value / 1000 + 'k';
}
},
gridLineWidth: 0,
minorGridLineWidth: 0
}, {
lineWidth: 1,
title: {
text: ''
},
labels: {
formatter: function () {
return this.value / 1000 + 'k';
}
},
gridLineWidth: 0,
minorGridLineWidth: 0,
linkedTo: 0,
opposite: true
}],
3 . On Hover Show All 3 labels. (As shown in the mock up)
tooltip: {
pointFormat: '{series.name} <b>${point.y:,.0f}</b> <br/>', //like in mock up
shared: true, //all series
crosshairs: true //vertical line
},
4 . Legend like "CPM IMPS SPEND BY TIME" with colors I mean I want to acheive same as in mock up.
so I already answered how do it in this question
Last Point to implement :
js:
tooltip: {
backgroundColor: null,
borderWidth: 0,
shadow: false,
useHTML: true,
style: {
padding: 0
},
and now you can customize your tooltip like you want:
.highcharts-tooltip>span p {
margin: 0;
}
.highcharts-tooltip>span span{
display: none;
}
#pCPM{background: rgb(87, 188, 0);}
#pIMPS{background: rgb(213, 156, 72);}
#pSPEND{background: rgb(12, 170, 226);}
Highchart's API don't allows you to set current values on axis, but you can disable default labels and put handmade labels with position absolute like I already doing with legend.

Highcharts - Area between two y values highlighted

I have a situation where I need to predict a trend in a time series, and I have to display confidence intervals. Is there a way to plot two sets of y-values in Highcharts as linked, and shade the area between the two? Something like this:
http://www.psychosomaticmedicine.org/content/74/4/377/F2.large.jpg
I have five time series: the prediction, two time series that bound the narrower confidence interval, and two more time series that bound the wider confidence interval.

The new Beta has that feature:
see jsFiddle
You can read more about the upcoming features in this post.

Highcharts does not natively support range charts (as of version 2.2.5), but there is a workaround. You can stack two area series on top of each other, with the foremost series having a background color matching that of the chart background.
And here is example javascript (that results in this chart):
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
defaultSeriesType: 'area'
},
title: {
text: 'Range chart emulation'
},
xAxis: {
},
yAxis: {
},
plotOptions: {
area: {
pointStart: 1940,
marker: {
enabled: false,
symbol: 'circle',
radius: 2,
states: {
hover: {
enabled: true
}
}
},
lineWidth: 0,
stacking: 'normal'
}
},
series: [{
// this series defines the height of the range
name: 'Range',
data: [1,2,3,5,7,8,9,6,4,7,5,3,4,7,6,5,6,7,5,4,2]
}, {
// this series defines the bottom values
name: 'Dummy',
data: [0,1,2,3,3.5,7,8.5,5,2.5,5.5,3,2,3,5.5,4,3,4,5.5,4,3.5,1.5],
enableMouseTracking: false,
showInLegend: false,
fillColor: 'rgba(255, 255, 255, 0)'
}]
});
});
