I need to have dates on my xaxis on my chart. I collect my data through a range datepicker where the user can enter a range of 14 days. I need the first value on the xaxis to be the start date of the range and the last value to be the end date of the range.
i want the the xaxis labels to read something like "27th Jan 2015" , "28th Jan 2015" or something in that direction and each tic to be 1 day. I've read the API-documentation and i've played around alot with the settings of the chart but for some reason i can not get it to work.
$('#graphColumn').highcharts({
title: {
text: '',
x: -20 //center
},
xAxis: {
categories: [dayArray[0], dayArray[1], dayArray[2], dayArray[3], dayArray[4], dayArray[5], dayArray[6], dayArray[7], dayArray[8], dayArray[9], dayArray[10], dayArray[11], dayArray[12], dayArray[13]]
},
yAxis: {
title: {
text: ''
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
valueSuffix: ''
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
credits: {
enabled: false
},
series: [{
showInLegend: false,
name: ' ',
data: series,
color: '#77B7C5',
marker: {
symbol: 'circle'
}
}, {
showInLegend: false,
name: '1 år sedan',
data: series1yearago,
color: "#71C73E",
marker: {
symbol: 'circle'
}
}]
});
here is my chart. I know the xaxis has categories set now but thats only for the moment, i know it should be datetime. My series are regular int arrays with one number on each index. I would apreciate any help that could be given here!
Edit: Here is a working jsfiddle example: http://jsfiddle.net/g0p00tLv/1
Your data, and how it is formatted, is what we really need to see.
You need to do one of two things:
1) pass your data as an array of [x,y] pairs, where x is either the epoch time stamp (in miliseconds), or a date.UTC object
2) pass your data as a single array of y values, and use the pointStart and pointInterval properties to set the date axis properly.

Right off the bat here is the desired chart in ChartJS.
We have two x-axes. One showing power from a meter and the other showing meter state over time (open, closed, or in standby) In both datasets the X axis is Unix time. The power Y axis is numerical and the state x axis is one of the three state categories. Both are drawn in lines.
To get right to the point: how do I do this in Highcharts? I have the second axis set up:
xAxis: {
type: 'datetime'
},
yAxis: [
{
title: {
text: 'Real Power'
}
},
{
type: 'category', //I have also removed this line
title: {
text: 'state'
},
categories: ['closed', 'standby', 'open']
}
],
Any attempt to set the Y axis value to a string in highcharts results in a well known: https://www.highcharts.com/errors/14/
Furthermore online I only seem to find categories on the X axis. Any help getting to the right place is appreciated. Thanks in advance.
You can't use a string as x value, use a number instead, for example:
series: [{
...
}, {
...,
yAxis: 1,
data: [1, 0, 2, 1]
}],
yAxis: [{
...
}, {
title: {
text: 'state'
},
categories: ['closed', 'standby', 'open'],
min: 0,
max: 2
}]

I want to create a stacked column chart using highcharts.js with datetime data
It works on line type, but not working on column. The result were flat 100%.
What i need is the chart will appear as stacked column. what do i missed?
I tried stacked: 'normal' on plotOptions, but still not working.
Please advise, thank you
My highcharts options:

}]
I suggest to disable, for debugging only, your definition for yAxis.labels. You will see original labels and realize how it works :)
In short, stacking renders each value on top of the previous one, for example: 1517018400000 + 1517018400000 = 3034036800000 so it renders point in 2066 year. And since all columns starts from zero (0) the distance is quite big: 136 years. Take a look: http://jsfiddle.net/BlackLabel/L4Lgbvvm/45/
Why it works for a line chart then? Simply, line type doesn't start at zero as column does. You can achieve the same result (without stacking) for column too, by setting series.threshold to null: http://jsfiddle.net/BlackLabel/n1s4sqps/
What about stacking? I'm not sure how this should work.. it works the same way for columns and lines, compare stackings:
line: http://jsfiddle.net/BlackLabel/n1s4sqps/1/
column: http://jsfiddle.net/BlackLabel/n1s4sqps/2/
If you could explain how stacking should be rendered in your opinion, let me know, maybe we can find some solution for it. An image of such stacking would be great.
I used pointInterval property to set interval as 30 days but my data set contains daily data.
That method is not working. chart is displaying all the points.
please check below image for the chart i got
https://docs.google.com/file/d/0B1wfs7NUcZnGQkk2QWdEbE9ndmM/edit
What is needed is to draw only three points for three months in the above chart.
Following is the code i used to do this.
Note that 'options.data.points' has data set in format of [[date,value],[]....]
var stockChartData = {
chart: {
renderTo: 'container'
},
title: {
text: "Stock Chart"
},
credits: {
enabled: false
},
yAxis: [
{
labels: {
align: 'left',
x: 2
},
title: {
enabled: false
},
lineWidth: 2
}
],
navigation: {
buttonOptions: {
enabled: false
}
},
scrollbar: {
enabled: false
},
series: [{data: options.data.points, type: 'line', pointInterval: 24 * 3600 * 1000 *30}]
};
stockChart = new Highcharts.StockChart(stockChartData, function (chart) {
});
please help me to solve this issue

The data set this example uses is in the format of [value,value,...] (see http://www.highcharts.com/samples/data/large-dataset.js).
So when pointInterval for a month is used, for example the last two values will be used for the values of last two months. For the same data when pointInterval for a year is used, the same last two values is used for the last two years. So the chart doesn't ignore the between values, therefore you will not have for example an average value of the month for day values.
EDIT:
You can use plotOptions.series.dataGrouping for grouping the day values in a month:

is it possible to set highcharts to show data only in specific time range, like 2 hours for example, without any zooming.
For example at the beginning i have data for 2 hours from now. And is it possible not to show some points if they do not fit 2 hours from now?
for example, on the highcharts x-axis labels will be always constant like: [12:00, 12:30, 13:00, 13:30, 14-00] even without any data that is related with this time.
And when the new data comes, labels of time shift to new values like: [12:30, 13:00, 13:30, 14:00, 14:30]
I tried to do like:
this.chart = new Highcharts.Chart({
chart: {
reflow: false,
type: 'line',
renderTo: newSensor.get('id')
},
title: {
text: newSensor.get('name')
},
xAxis: {
minRange : 1
},
yAxis: {
title: {
text: 'Values'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
series: dataToChart,
plotOptions: {
series: {
lineWidth: 1,
turboThreshold: 0,
threshold: null
}
}
});
But minRange is not right property for this.
I think you should set min and max for xAxis. Then, when new point is added (using addPoint() ) you should set new extremes using
chart.xAxis[0].setExtremes( newMin, newMax )
$(function () {
$('#container').highcharts({
chart: {

label : {

}
},

text: 'PRICE Rs. / SQ.FT.'
},

plotLines: [{

}]
});
});
My x-axis having Years and data series having information which i want to show on Y axis.
When i remove the interval from 2010 to 2022 i . e comment min and max option highcharts draws a graph starting from 1970 , but no points afterwards.
http://jsfiddle.net/R8kx7/3/ here is the link
Based on your comments to #SteveP answer, if you don't want to explicitly pair x values to each y for each series, use the plotOptions.series pointStart and pointInterval properties.
plotOptions: {
series: {
pointStart: Date.UTC(2011, 0, 1),
pointInterval : 12*30*24*3600* 1000
}
},
series: [{
data:[2165,1831,2798,2200,2237,2799,2400,2500,2865,2850]
}]
Updated fiddle here.
Although you are specifying min and max, your data has no x values specified, so it is assuming that the date time values are starting at 0. There are several ways to render the chart you want.
Firstly, you could specify x values in your data points e.g.
{x:Date.UTC(2011, 0, 1),y:2165}
Another way is to not use a datetime axis type, and just specify the categories you want in the x-axis:
categories:["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"]
The second option is probably a bit simpler http://jsfiddle.net/K6xxz/
