I want create a bar line graphs with navigator,range selector, y axis from both side and graph sector. I implement it using Highcharts.Chart() but it's x-axis not comes properly. when i create x-axis properly after change categories to ["2017-2-3'] then range selector goes to 1970 (default value) so i convert date to milliseconds. Now in the x-axis have unwanted values. I want to show only x-axis values which shows in category array. currently 1m,3m,6m not worked i think it happen because of this x-axis issue.

Just comment the tickInterval for the xAxis
//tickInterval : 2,
Fiddle
First of all, you have unsorted data. If you want to invert your data, use reversed option.
Also, the rangeSelector and the tickInterval are wrong. If you use datetime axis, then the basic unit is one millisecond.
However, to show dates only from the categories array, use the tickPositions option and formatter function for labels:
xAxis: {
reversed: true,
minRange: 1,
type: 'datetime',
tickPositions: categories,
labels: {
formatter: function() {
return Highcharts.dateFormat('%Y-%m', this.value);
}
}
},

API Reference:
https://api.highcharts.com/highcharts/xAxis.reversed
https://api.highcharts.com/highcharts/xAxis.tickPositions
https://api.highcharts.com/highcharts/xAxis.labels.formatter
(1) First always make sure that you are injecting timestamps in your categories, and formatting them in :
(1-1) xAxis.labels.formatter function [for x axis labels]
(1-2) navigator.xAxis.labels.formatter function [for navigation labels format)
(2) Second make sure that you are clearing your (xAxis.categories) if you push data into it. because highcharts don't sort your array. if you just assign new array that's ok.
(3) Note : Based on values on your categories array, navigation gets some values like xAxis min and xAxis Max. when you change your data these values remain and that's why your navigation collapses. so when changing data make sure to update. you can use 0 for minimum of navigator and categories.length for maximum value of navigator.
you can access updated values also in dataMin and dataMax.
Hope this answer help you.
Im trying to make this chart have multiple Y Axes, all of which have different values and tick intervals. Like Signal Strength be on a scale of 0%-100%, Temperature 0F-100F and Main Power be 0V to 25V but cant seem to figure it out. Here's my jFiddle:
http://jsfiddle.net/0k5k8ygz/
Code:
function createChart() {
Highcharts.stockChart('container', {
rangeSelector: {
selected: 4
},
yAxis: [{ // Primary yAxis
labels: {
format: '{value}°F',
style: {
color: Highcharts.getOptions().colors[2]
}
},
title: {
text: 'Temperature',
style: {
color: Highcharts.getOptions().colors[2]
}
},
opposite: true
}, { // Secondary yAxis
gridLineWidth: 0,
title: {
text: 'Main Power',
style: {
color: Highcharts.getOptions().colors[0]
}
},
labels: {
format: '{value} volts',
style: {
color: Highcharts.getOptions().colors[0]
}
}
}, { // Tertiary yAxis
gridLineWidth: 0,
title: {
text: 'Signal Strength',
style: {
color: Highcharts.getOptions().colors[1]
}
},
labels: {
format: '{value} %',
style: {
color: Highcharts.getOptions().colors[1]
}
},
opposite: true
}],
plotOptions: {
series: {
compare: 'percent',
showInNavigator: true
}
},
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.y}</b> ({point.change}%)<br/>',
valueDecimals: 2,
split: true
},
series: seriesOptions
});
}
$.each(names, function(i, name) {
$.getJSON('https://www.highcharts.com/samples/data/jsonp.php?filename=' + name.toLowerCase() + '-c.json&callback=?', function(data) {
seriesOptions[i] = {
name: name,
data: data
};
// As we're loading the data asynchronously, we don't know what order it will arrive. So
// we keep a counter and create the chart when all the data is loaded.
seriesCounter += 1;
if (seriesCounter === names.length) {
createChart();
}
});
});
If you add some data to each of the y-axes, they will get tick marks automatically. You assign data to a specific y-axis using the series.yAxis index:
seriesOptions[i] = {
name: name,
data: data,
yAxis: i,
};
If you also want to specify a valid range for the y-axes, you can set min and max on each individual axis:
...
labels: {
format: '{value} volts',
},
min: 0,
max: 25,
...

I am having some difficulty getting pointRange to work for a HighStock combination chart I've written.
You can see the issue here, the bars should be 28 days wide but they are not. I can get this code to work on a non-HighStock chart but something is preventing it from working in HighStock and I've been unable to figure it out.

I am struggling to solve this issue where I have a Highcharts graph with temperature and humidity.
It has two y-axis, one for temperature and one for humidity.
I have specified that humidity should go to the y-axis id 1, but it does not.
It puts the line in, but it is 'plotted' to the temperature axis values.
See this jsfiddle
$(function () {
$('#container').highcharts({
chart: {
zoomType: 'x',

Can anyone help me solve this?
It is very simple, yaxis option should be yAxis since JS is case-sensitive.
I think that's it: jsFiddle
http://jsfiddle.net/gabrielesandoval/efHq7/
Is there a way to fill in the gap between the y-axis and the first point. The first point on my chart should be "25 years" and i would like the area between 0 and 25 to be filled in as well. Even if the tooltip doesn't work for that point, I would just like to visually show that the values between 0 and the first point.
I tried adding a point with a x value of zero but that didnt work. The only area charts I have seen where there is no gap between the two axis and the area are examples where the chart is inverted. Is there a proper way to do this?
Current Code:
$(function () {
$('#container').highcharts({
chart: {
type: 'areaspline'
},
title: {
text: 'Monthly Comparison'
},
subtitle: {
text: '1 vs 2'
},
xAxis: {
min: 0,
categories: [0, '25 years', '30 years', '35 years', '40 years', '45 years']
},
yAxis: {
labels: {
formatter: function() {
return '$' + this.value;
}
},
min: 0,
title: {
text: 'Cost'
}
},
tooltip: {
shared: true,
valuePrefix: '$'
},
credits: {
enabled: false
},
legend: {
enabled: false
},
plotOptions: {
area: {
lineWidth: 1,
marker: {
enabled: false
},
shadow: false,
states: {
hover: {
lineWidth: 1
}
}
}
},
series: [{
type: 'area',
name: 'series1',
data: [['',60],['25 years',60], ['30 years',60], ['35 years',60], ['40 years',60], ['45 years',60]]
}, {
type: 'area',
name: 'series2',
data: [['',90], ['25 years',100], ['30 years',175], ['35 years',300], ['40 years',400], ['45 years',400]]
}]
});
});
You should set minPadding/maxPadding as 0, but these parameters doesn't work with categories. So you need to use numeric xAxis, instead of categories.
