Line extending below chart area in multi-pane Highstock chart - highcharts

I am having a problem with Highstock. I have a multi-pane chart (multiple charts stacked on top of each other). When I specify a min and max value for the y-axis, if any value in the series is less than the min value, it will extend below the chart, usually extending into the chart below. For some reason, the same is not true for when a data point is above the max value. I can't tell if this is a bug in Highstock or just something I am doing wrong.
I understand that this is an unusual use case for Highstock, but it is necessary for the application I am developing. The only example I can find for multi-pane charts with Highstock is on their demo page at http://www.highcharts.com/stock/demo/candlestick-and-volume, but that is a different situation.
Please see my example: http://jsfiddle.net/afoster777/UJaJG/
Here is my configuration:
var chart = new Highcharts.StockChart({
chart: {
renderTo: 'container',
alignTicks: false,
plotOptions: {
shadow: false,
series: {
connectNulls: false
},
plotBorderColor: "#CCCCCC",
plotBorderWidth: 2,
plotBackgroundColor: "#FFFFFF"
}
},
navigator: {
enabled: false
},
xAxis: {
title: {
text: 'Time'
},
type: 'datetime',
ordinal: false
},
yAxis: [{
title: {
text: "Y"
},
min: 0.8,
max: 0.9,
labels: {
align: 'right',
x: -6,
y: 3
},
lineWidth: 1,
height: 250,
offset: 0,
startOnTick: false,
endOnTick: false
}, {
title: {
text: "Y"
},
min: 0.8,
max: 0.9,
labels: {
align: 'right',
x: -6,
y: 3
},
lineWidth: 1,
top: 320,
height: 250,
offset: 0,
startOnTick: false,
endOnTick: false
}],
series: [{
type: 'line',
id: 0,
name: 'Series1',
yAxis: 0,
data: series1data,
marker: {
enabled: false
},
tooltip: {
valueDecimals: 2
},
gapSize: 2,
connectNulls: false
}, {
type: 'line',
id: 1,
name: 'Series2',
yAxis: 1,
data: series2data,
marker: {
enabled: false
},
tooltip: {
valueDecimals: 2
},
gapSize: 2,
connectNulls: false
}]
});
I would appreciate any suggestions.
Edit: Apparently there is an open issue about this already (Issue# 1387). Does anyone have any ideas for a workaround?

Apparently github user sappling has made a fix for this problem and submitted a pull request. I included sappling's version of Highstock <script src="http://raw.github.com/sappling/highcharts.com/clip/js/highstock.src.js"></script> instead of the vanilla one, and the problem seems to be fixed. http://jsfiddle.net/afoster777/jEZ9w/

highcharts - Align y-Axis labels to the right and make chart width "smaller"

I have a chart with two y-Axis. One to the left of the chart another one to the right.
The labels on the right y-Axis appear inside the chart. When I align the labels to the right the labels still overlap the y-Axis in some cases. When I add a distance x: 30, the distance becomes bigger but the labels are not fully shown anymore as they are outside the chart.
I want the labels to have a similar distance to the y-Axis as for the left y-Axis and still shown inside the chart "area".
Here a jsfiddle: https://jsfiddle.net/smaica/zrn87q0b/32/

Thanks!
In Highstock, the yAxis.labels.align is right by default, but yAxis is the opposite as well. It might seem not intuitive, but you only need to change yAxis.labels.align to 'left'.

Want to make the Highcharts Bar Chart data labels appear on the far right in the chart

I am looking for the desired output like so:
series.dataLabels.align: left/right` isn't cutting it. It only makes it appear just after the blue rectangle of each bar and not on the far right, which is not what I want. I have also looked at the highcharts api a little bit and I was not able to find a chart option that gets the job done. Thanks in advance.
My current chart options:
var options = {
chart: {
renderTo: 'container',
type: 'bar',
},
credits: {
enabled: false
},
colors: ['#024a7a'],
title:{
text:null
},
plotOptions: {
bar: {
animation: false
},
series: {
showInLegend: false,
states: {
hover: {
enabled:false
}
}
}
},
tooltip: {
enabled: false
},
xAxis: [{
categories: ['SAC 1', 'SAC 2', 'SAC 3'],
lineWidth: 0,
minorGridLineWidth: 0,
lineColor: 'transparent',
minorTickLength: 0,
tickLength: 0
}],
yAxis: [{
gridLineWidth: 0,
labels: {
enabled: false
},
minorGridLineWidth: 0,
title: {
text: null
}
}],
series: [{
data: [10, 5, 15],
dataLabels: {
align: 'left',
enabled: true
}
}]
};
var chart = new Highcharts.Chart(options);
});
One of the ways to achieve that effect is passing specific xAxis and yAxis configuration objects, which contains few parameters:
xAxis: [{
opposite: true,
type: 'category',
labels: {
formatter: function() {
return this.chart.series[0].processedYData[this.pos] + ' %'
},
},
lineWidth: 0,
minorTickWidth: 1,
tickWidth: 0
},
yAxis: {
title: {
enabled: false
},
labels: {
enabled: false
},
gridLineWidth: 0,
max: 100
},
Configuration above fills labels by the series data values, so you should prepare series array similar like below:
series: [{
data: [31, 15, 9, 5]
}],
Lets look for this JSFiddle:

Highcharts - Equal spacing between ticks with provided tickPositions

Highcharts.chart('container', {
chart: {
height: 'some height',
},
title: {
text: ""
},
legend: {
enabled: false
},
credits: {
enabled: false
},
series: [], // data
xAxis: {
title: {
enabled: false
},
lineWidth: 1,
lineColor: 'white',
tickAmount: 5,
min: 100000000,
max: 1000000000000,
tickPixelInterval: 100,
tickPositions: [1000000000, 10000000000, 100000000000, 1000000000000]
},
yAxis: {
height: '100%',
title: {
enabled: true,
text: 'Investment'
},
tickAmount: 10
}
})
The above code produces something like this
The labels on the xAxis are overlapping as the range is quite high(Ranging from 100 million to 1 trillion).
On reading highcharts API doc, I found that the method tickPositions overwrites the values in tickPixelInterval & tickInterval. That's why I'm not able to specify custom tickInterval value.
What I want is, to keep equal spacing between each of the mentioned tickPositions. It'll be fine if the bubbles overlap.

Highcharts polar area label customization

I'm creating a polar area chart in Highcharts. I'm having issues with the labels being positioned inside the chart. See an example here:
$('#container').highcharts({
chart: {
polar: true,
backgroundColor: 'transparent',
plotBorderWidth: null,
margin: [0, 0, 0, 0],
spacingTop: 0,
spacingBottom: 0,
spacingLeft: 0,
spacingRight: 0
},
title:{
text:''
},
subTitle:{
text:''
},
pane: {
startAngle: 0,
endAngle: 360
},
legend: {
enabled: false
},
xAxis: {
tickInterval: 45,
min: 0,
max: 360,
lineWidth: 0,
minorGridLineWidth: 0,
gridLineColor: 'transparent',
labels: {
enabled: false
},
},
yAxis: {
min: 0,
lineWidth: 0,
minorGridLineWidth: 0,
gridLineColor: 'transparent',
labels: {
enabled: false
},
},
plotOptions: {
series: {
pointStart: 0,
pointInterval: 45,
pointPlacement: 'between',
states: {
hover: {
enabled: true
}
},
dataLabels: {
enabled: true,
format: '<span class="wheel-label" style="color: {point.color}">{point.name}</span>',
style: {
textShadow: false,
width: 150,
fontSize: "16px"
},
}
},
column: {
pointPadding: 0,
groupPadding: 0,
borderWidth: borderWidth
},
},
series: [{
showInLegend: false,
type: 'column',
name: 'Column',
data: data
}],
credits: {
enabled: false
}
});

I notice with the pie charts there are options for "distance" but no such option exists for the polar chart. I'd also like to be able to use "connectors" if possible but I don't see this available for polar either. How can I get more control over these labels?
I've had similar problems getting labels to be "pushed" out from the borders of a polar/spider chart. The way I solved this was to use plot bands to put a ring around the outside rim.
My test can be found here: http://jsfiddle.net/brightmatrix/j3v0zstk/
In this case, I added the following line to your yAxis:
plotBands: [ { from: 8, to: 15, color: '#FFFFFF', zIndex: 5 } ]
The values I used are merely for illustration. If you wanted the colored wedges in your chart to truly go out to 10, define a max value for your yAxis and have the plot bands cover what would extend past the chart edges.
The zIndex value of "5" makes sure the plot bands sit on top of your chart wedges to give the desired effect.
I hope this is helpful!
I managed to fix it by allowing the labels to extend outside the container, then setting the container to overflow:visible. Not ideal but it works.
dataLabels: {
enabled: true,
crop: false,
overflow: 'none',
padding: 50,
useHTML: true,
verticalAlign: 'middle',
format: '<div class="wheel-label" style="color: {point.color}">{point.name}</div>',
style: {
textShadow: false,
width: 250,
fontSize: '22px'
},
}
http://jsfiddle.net/c904atb3/2/
In my production code I added a CSS class to each label based on the name so I can tweak positioning in CSS.
You can set label's coordinates like this:
var data = [{
name: "Label 1",
dataLabels: {
x:100,
y:100
},
y: 10,
color: "#9fe642"
},

How to enable the vertical scrollbar in Highcharts?

Here is my following chart config. I have been doing some research but couldn't find any help to enabling vertical scrollbar.
I know that I can set overflow-y property for chart container div, but to achieve frozen X-axis I need vertical scroll on series that is not container.
$(function () {
$('#container').highcharts({
chart: {
type: 'bar'
},
title: {
text: 'Stacked bar chart'
},
xAxis: {
categories: ['CITY1', 'CITY2','CITY3','CITY4'],
minorTickLength: 0,
tickLength: 0,
lineWidth: 0,
tickwidth: 0,
},
yAxis: {
max: 100,
tickInterval: 25,
title: {
text: 'Total fruit consumption'
}
},
legend: {
reversed: true
},
plotOptions: {
series: {
grouping: false,
stacking: 'normal'
}
},
scrollbar: {
enabled: true
},
series: [{
name: 'Q1',
data: [50, 70,0,35]
},{
name: 'Q2',
data: [20, 0,50,0]
},{
name: 'Q3',
data: [0, 0,40,20]
},{
name: 'Q4',
data: [0, 30,0,20]
}]
});
});
Can anybody suggest me how to enable the vertical scrollbar in Highcharts?
#Swetha: That fiddle is using Highstock library. Highcharts does not support scrollbars. Scrollbars are Highstock only
http://www.highcharts.com/docs/chart-concepts/scrollbar
You could set a fixed height or width to the chart and wrap into a div width overflow-x:auto, it's not the same but it is something at least.
Try this fiddle: http://jsfiddle.net/fj6d2/3076/
This may help you.
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type:'bar',
},
xAxis: {
categories: ['CITY1', 'CITY2','CITY3','CITY4'],
min:2,
},
yAxis: {
title: {
text: 'Total fruit consumption'
},
},
plotOptions: {
series: {
grouping: false,
stacking: 'normal'
}
},
legend: {
verticalAlign: 'top',
y: 100,
align: 'right'
},
scrollbar: {
enabled: true
},
series: [{
name: 'Q1',
data: [50, 70,0,35]
}, {
name: 'Q2',
data: [20, 0,50,0]
}, {
name: 'Q3',
data: [0, 0,40,20]
},{
name: 'Q4',
data: [0, 30,0,20]
}]
});
