I can get the noData overlay working when there are no series data values, and I can get the x-axis displaying along with the noData label by setting a xAxis.max value, but I can't get the x-axis labels displaying.
Any ideas?
Ideally I would be able to do this without any fake series data (as without data I don't have any series names to provide). This is used in a column chart of well defined x values (like in the js fiddle below, with known fruits, where only each series counts are dynamic)
Closest I've been able to get is this jsfiddle:
http://jsfiddle.net/eLdn6Lfc/
$(function () {
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container1',
type: 'column'
},
xAxis: {
categories: ['Mulligatawny', 'Crab bisque', 'Lima bean', 'Wild mushroom'],
max:3
},
series: [{
data: []
}],
lang: {
noData: "No Soup For You!"
},
});
});
You also need to set min limit to x-axis if there is no data.
Working solution here
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'column'
},
xAxis: {
categories: ['Mulligatawny', 'Crab bisque', 'Lima bean', 'Wild mushroom'],
min: 0,
max: 3
},
series: [{
showInLegend: false,
data: []
}],
lang: {
noData: "No Soup For You!"
},
});

I am tried to get the series from the already displayed highchart and use that series to plot a new chart in another one html div, i have written below code to achieve this,finally i get the series from existing graph but can't render to the new html div
var data = chart.series; // series from already displyed
jQuery('#commonModal_res').highcharts({
chart: { zoomType: 'x'},
title: { text: "" },
subtitle: { text: 'Click and drag in the plotted area to zoom in' },
xAxis: { type: 'datetime' },
legend: { enabled: false },
series: data,
});
note : throwing too many recursion error
The problem occurs because you're trying to assign the complete and already built series object, instead of configuration object which is required. In order to make it work, you need to assign the configuration object by this way:
$('#new_con').highcharts({
chart: { zoomType: 'x'},
title: { text: "" },
subtitle: { text: 'Click and drag in the plotted area to zoom in' },
xAxis: { type: 'datetime' },
legend: { enabled: false },
series:charts[0].userOptions.series,
});
Then your chart should be rendered properly.
Additionaly, you can access appropriate chart by the Highcharts.charts array on global Highcharts object, where all charts are stored, just like that:
series: Highcharts.charts[0].userOptions.series,
In this case creating new charts array is unnecessary.

I have some data I wish to display on a chart but it just shows the title and no points get drawn. The JSON data I receive is correct as per my knowledge, I think it's somewhere in the chart function but I can't really point it out.
This is what I have so far:
data.php (the output):
{"name":"Temperature","data":[34,28,29,28,34,28,32,27,24,30,25,32,34,28,34,33,24,33,30,27,24,27,26,29]}
The important bits of the html:
<script>
$(function () {
var chart;
$(document).ready(function() {
$.getJSON("data.php", function(json) {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'line',
marginRight: 130,
marginBottom: 25
},
title: {
text: 'Temperature vs. Time',
x: -20 //center
},
xAxis: {
categories: ['12AM', '1AM', '2AM', '3AM', '4AM', '5AM', '6AM', '7AM', '8AM', '9AM', '10AM', '11AM','12PM', '1PM', '2PM', '3PM', '4PM', '5PM', '6PM', '7PM', '8PM', '9PM', '10PM', '11PM']
},
yAxis: {
title: {
text: 'Temperature'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
series: json
});
});
});
});
</script>
It's supposed to show temperature per hour but unfortunately nothing comes up. Any idea what could be wrong?
series should be an array. So you need to just change:
series: json
To:
series: [json]
Working example: http://codepen.io/anon/pen/Kfgsd
Documentation: http://www.highcharts.com/docs/chart-concepts/series
your problem i think that you haven't specified where your chart should be inserted to, afaik you either should specify the renderTo option for the class constructor options or use the $('#container').haighcharts({...}) jquery helper
I have a JSON file of the following format :
[
{ name: 'Pay Off',
data: [ [2850,0],
[3135,0],
[3420,0],
[3705,0],
[3990,0],
[4275,0],
[4560,0],
[4845,0],
[5130,0],
[5415,0],
[5700,0],
[5985,285],
[6270,570],
[6555,855],
[6840,1140],
[7125,1425],
[7410,1710],
[7695,1995],
[7980,2280],
[8265,2565],
[8550,2850]
]
},
{
name: 'Profit',
data: [ [2850,-250],
[3135,-250],
[3420,-250],
[3705,-250],
[3990,-250],
[4275,-250],
[4560,-250],
[4845,-250],
[5130,-250],
[5415,-250],
[5700,-250],
[5985,35],
[6270,320],
[6555,605],
[6840,890],
[7125,1175],
[7410,1460],
[7695,1745],
[7980,2030],
[8265,2315],
[8550,2600]
]
}
]
I have to plot graph for 'Pay Off' and 'Profit' together. Even more plots maybe added to the list as per requirement. The data array has x-axis as 0th element and y-axis as 1st element.
What I am currently doing is the following -
$(document).ready(function() {
var options = {
chart: {
renderTo: 'container',
type: 'line'
},
title: {
text: 'PayOff Curve'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: []
};
$.getJSON('data.json', function(list) {
var newseries = {
name: '',
data: []
};
$.each(list, function(i,item){
newseries.name = item.name;
newseries.data = item.data;
options.series.push(newseries);
});
// Create the chart
var chart = new Highcharts.Chart(options);
});
But I don't any graph at all. I can't figure out the issue with it as I am new to both JavaScript and Python. Please suggest an efficient method to do this.
Thanks for your help..
Your JSON isn't proper one, try to validate it. Properties names shold have double quotes, change from: name: 'Pay Off' to: "name": "Pay Off"
Your JSON is valid for a highcharts series - you don't need to try to transform it at all:
$(document).ready(function() {
var options = {
chart: {
renderTo: 'container',
type: 'line'
},
title: {
text: 'PayOff Curve'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: []
};
$.getJSON('data.json', function(list) {
options.series = list; // <- just assign the data to the series property.
var chart = new Highcharts.Chart(options);
});
});
If that still doesn't work, open the console to see whether there's a JavaScript error.
Here's a fiddle.
I have a problem with Shield UI Chart. I need to hide all text on my X axis, that is dateTime. But i can't visualize the chart when I add the code that hides the axis.
Below is the code that I am using. Will appreciate any assistance fixing it.
<script type="text/javascript"> $(function () { $("#chart").shieldChart({
axisX: {
axisTickText: {
enabled: false
}
axisType: 'datetime'
},
axisY: {
title: {
text: "Total Sales statistics"
}
},
primaryHeader: {
text: "Aaron's cars sales"
}, dataSeries: [{ seriesType: 'bar',
collectionAlias: 'New Cars Sales Volumes',
data: [325000, 425000, 316000, 378000, 390000]
}, {
seriesType: 'bar',
collectionAlias: 'Used Cars Sales Volumes',
data: [125000, 175000, 158000, 130000,101000,98000]
}]
});
});
</script>
You have forgotton to put a comma between the different properties. You have axisTickText:{} and there must be a comma, because there is one more property following- axisType.
axisX: {
axisTickText: {
enabled: false
},
axisType: 'datetime'
},
I'm plotting a chart where the x axis is a datetime. My data contains lots of sample from each day, and the resulting chart is jittery.
Is there an easy way to get highcharts to only display 1 or 2 datapoints from each day, to make the chart smoother?
http://jsfiddle.net/RjPRd/72/
var data = [[1354282654000,13],[1354285785000,13],[1354289387000,14],[1354292990000,15],[1354296592000,13],[1354419090000,20],[1354422692000,21],[1354426295000,20],[1354435425000,19],[1354438087000,19],[1354538087000,24]];
var options = {
chart: { renderTo: 'graph' },
xAxis: { type: 'datetime' },
series: [{data: data}]
};
var chart = new Highcharts.Chart(options);
If you are asking if HighCharts can do interpolation/projections then the answer is no.
What you can do is pre-process your data or use HighStock with dataGrouping. Here is a very basic example.
This is the code that does it:
plotOptions: {
series: {
dataGrouping: {
approximation: 'average', //default
units: [[
'day',
[1]
]]
}
}
