I use Windbarbs in my charts. However, the data for the windbarbs must be in m/s and therefore the tooltips show the same unit.
I want to display the km/h figure and unit in the tooltip. I use the code:
thisChart.addSeries({
name: 'WindBarbs',
xAxis: 1,
color: 'black',
type: 'windbarb',
visible: true,
dataGrouping: {
enabled: true,
units: [
['hour', [3]]
]
},
tooltip: {
pointFormat: '{series.name}: {point.y * 3.6}',
valueSuffix: ' km/h',
},
data: WindBarbData
}, false);
However this does not work.
What do I do wrong, how to accomplish this?
NOTE: Windbarbs as tag does not exist. Cannot create it.
This behavior don't occurs due to valueSuffix but because of two mistakes in tooltip.pointFormat.
First of all, in pointFormat option should be used point.value instead of point.y.
Demo:

API Reference:
https://api.highcharts.com/highcharts/series.windbarb.tooltip.pointFormat
Secondly, multiplication is not possible in the pointFormat option. If you need to make some calculations, use pointFormatter to achieve that.

Can someone help me to understand what is wrong here. Everything seems perfect.

heatMap showing lines instead of squares
The exact answer is rowsize: 500 (from UI perspective - height, YAxis difference between each point) and colsize: 86400000 (one day each, x-axis difference between each point). Missing this was causing box not to appear.
As I understood you would like to achieve something like is rendered here: http://jsfiddle.net/BlackLabel/o6ywag42/
Notice how the data structure looks like in this demo from Highcharts demo base:
https://jsfiddle.net/BlackLabel/uofntb4y/ - if you want to keep the points as a square the 'y' value must be growing one by one, like here: http://jsfiddle.net/BlackLabel/o7bgq1pu/
And to show your truly y scale you can use the categories feature.
yAxis: {
categories: ['18000', '18500', '19000']
},
API: https://api.highcharts.com/highcharts/yAxis.categories
EDIT:
Another solution suggested by #prakash is to use the series.rowsize property and series.colsize to fit the squares.

I'm importing a csv file using Highcharts cvsURL for a line chart. I'm using styledMode and I defined the default colors. Highcharts is using my stylesheet. Is there an easy way to tell each series which color to use?
I have lots of lines, so highcharts cycles through its 10 default colors. I need one of the colors to only be assigned to 2 specific series though.
Here is my code so far:
Highcharts.chart('container', {
chart: {
type: 'line',
styledMode: true //this totally separates the design from the svg.
},
data: {
itemDelimiter: ',',
csvURL: 'http://deq.at.utah.gov/wp-content/themes/deq/parts/charts/Ozone-4th-Highest-8hr-Front.csv'
},
title: {
text: 'Ozone 4th Highest 8-hr Concentration Wasatch Front'
},
yAxis: {
title: {
text: '(Ozone PPM)'
}
}
});
I think the API said something about assigning classes to a series. Maybe that would work because I could make custom CSS for only those series, but I can't see how to do that using csvURL.
You can define color or className for series in this way:
data: {
csvURL: '...'
},
series: [{
color: '#00c735'
}, {
color: '#c4392d'
}]

I use Highcharts to visualize 3D charts in my project. Particularly I am interested in showing a 3D scatter plot like this. Below the chart you can see the options as well as the respective jsFiddle.
Is there a possibility to display a label with every point's name always i.e. that hovering is not required?
Thanks!
Within the series you can enable the datalabels like this:
series: [{
dataLabels: {
enabled: true,
},
}]
http://jsfiddle.net/oghokm8w/1/
then you could use the formatter to customise the text to be displayed:
series: [{
dataLabels: {
enabled: true,
formatter: function () {
return this.point.x;
},
}
}]
I'd like to remove the value box from a Highcharts angular gauge.
I'm not sure it is possible...I have tried messing around with the JSFiddle demo trying to remove it and haven't been able to.
I was able to remove the minor and major ticks by adding
minorTickInterval: 'none',
tickPixelInterval: 'none'
But I can't figure out how to remove the value from the middle of the gauge.
or you can achieve the result you want just by adding the following lines:
series: [{
dataLabels: {
enabled: false
}
}]
You should add dataLabels.formatter to the series part of your gauge to remove it.
dataLabels: {
formatter: function () {
return null;
}
},

I have two datasets (red, blue) that have data starting in 9/11 and one (green) with data starting in 2/13. The green one is starting in the same location as the others, but it should start in 2/13. How can I tell this dataset to do that? I'd rather not use 0's if there is a way around it.
You can put JavaScript's null value if you don't have any value. My English may not be that much good to explain but my example is clear. Also you can look at that page: http://www.highcharts.com/demo/area-missing/gray
<script>
$(function () {
$('.graph').highcharts({
chart: { type: 'line'},
plotOptions: { series: { connectNulls: true }},
xAxis: {categories: [2012,2011,2010,2009] },
yAxis: {title: { text: 'Example Fruit Consumption'}},
series: [
{ name:'Apple', data:[null,null,20000,41000]},
{ name:'Orange', data:[29458,29000,26892,23256]}
]
});
});
</script>
You can define pointStart() http://api.highcharts.com/highcharts#plotOptions.series.pointStart for serie.
