I am using histogram bell curve for a project, everything is working fine except flag position like given in picture.
Here is link of my jsfiddle https://jsfiddle.net/8q1t3mwb/4
var data = [1,2,3,4,5,6,7,8,9,10];
Highcharts.chart('container', {
title: {
text: 'Bell curve'
},
xAxis: [{
title: { text: 'Data' }
}, {
title: { text: 'Bell curve' },
opposite: true
}],
yAxis: [{
title: { text: 'Data' }
}, {
title: { text: 'Bell curve' },
opposite: true
}],
series: [{
name: 'Bell curve',
type: 'bellcurve',
id:'dataseries',
xAxis: 1,
yAxis: 1,
baseSeries: 1,
zIndex: -1,
color: {
linearGradient: {
x1: 0,
y1: 0,
x2: 1,
y2: 0
},
stops: [
[0, 'rgb(255, 255, 255)'],
[1, 'rgb(200, 200, 255)']
]
}
}]
});

You see the points where they currently are because your flags are on the scatter axis. If you turn on the scatter points, you will see that.
Therefore, if you set the following for the flag series:
{
yAxis: 1,
xAxis: 1,
name: 'Pointer',
type: 'flags',
...
}
And adjust your x value according to the number on the bell curve you will be able to see the flag connected to the curve.

Why are the columns in the demo code handing above the x axis. How do I make them stick to x axis.
Look at the https://jsfiddle.net/nmLo2sbu/
Highcharts.chart('container', {
chart: {
type: 'column'
},
title: {
text: 'Stacked bar chart'
},
xAxis: {

offset:0,
},
yAxis: {
title: {
text: 'Total fruit consumption'
},
},
plotOptions: {

minPointLength: 3,
// stacking: 'normal'
}
},
series: [{

data: [0, 0, 0, 0, 0]
}, {

data: [0, 0, 0, 0, 0]
}]
});
Highcharts are not able to calculate extremes on yAxis, so tick 0 is placed in the middle. Additionally, the default value in column series for threshold is 0. You can force to calculate extremes for example by using softMax property.
yAxis: {
...,
softMax: 1
}

How to make changes in highcharts time series zoomable chart to get similar to the one mentioned in below link:

Used JS :
$.getJSON(

},
yAxis: {

}
},
legend: {

},

y2: 1
},
stops: [
[0, Highcharts.getOptions().colors[0]],

]
},
marker: {

},
lineWidth: 1,
states: {
hover: {
lineWidth: 1
}
},
threshold: null
}
},
series: [{
type: 'area',
name: 'USD to EUR',
data: data
}]
});
}
);
I have a high chart code like this:
Highcharts.chart('linechart', {
chart: {
backgroundColor:'rgba(255, 255, 255, 0.8)',
borderRadius:5,
},
title: {
text: 'ROC Graph'
},
subtitle: {
text: 'Learning Evaluation'
},
xAxis: {
min: 0,
max: 1,
tickWidth:1,
tickPositions: [0.001, 0.01, 0.1,1]
},
yAxis: {
max: 1,
tickInterval:0.1,
title: {
text: 'Number of Employees'
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle'
},
plotOptions: {
series: {
pointStart: 0.30
}
},
});
And my javascript code:
for(j=0; j<data.roc_buffer[i]['xs'].length/10;j++){
x_plot = data.roc_buffer[i]['xs'][10*j]
y_plot = data.roc_buffer[i]['ys'][10*j]
plot_buffer[j] = {'x':x_plot, 'y':y_plot}
}
roc_chart.addSeries({
name: data.roc_buffer[i]['plotname'],
data: plot_buffer
});
It work out fine like this
However, I want the [0.001,0.01,0.1,1] all have same width so I need to adjust the xaxis to type logarithm. So I switch my code to:
xAxis: {
type: 'logarithmic',
minorTickInterval: 0.1
},
Now the line disappear...
Also my data is something like
[{x:integer,y:integer},{x:integer,y:integer},{x:integer,y:integer},...]
What I understand.
Your xAxis and yAxis both value dynamically generated.
You can set data using setData method for yAxis and setCategories for xAxis.
$('#button').click(function () {
highchart.series[0].setData([1, 2, 4, 8, 16]);
highchart.xAxis[0].setCategories(['J', 'F', 'M', 'A', 'M']);});

I'm trying to update the highchart line graph say every minute. something like shown in this link jsfiddle
Right now, I use a periodic javascript call to the function that draws the graph. The problem is that it starts to draw it from beginning.
Is it possible to just add the new data point to the existing line?
$(function () {
$.getJSON('https://www.highcharts.com/samples/data/jsonp.php? filename=usdeur.json&callback=?', function (data) {
$('#container').highcharts({
chart: {
zoomType: 'x'
},
title: {
text: 'USD to EUR exchange rate over time'
},
subtitle: {
text: document.ontouchstart === undefined ?
'Click and drag in the plot area to zoom in' : 'Pinch the chart to zoom in'
},
xAxis: {
type: 'datetime'
},
yAxis: {
title: {
text: 'Exchange rate'
}
},
legend: {
enabled: false
},
plotOptions: {
area: {
fillColor: {
linearGradient: {
x1: 0,
y1: 0,
x2: 0,
y2: 1
},
stops: [
[0, Highcharts.getOptions().colors[0]],
[1, Highcharts.Color(Highcharts.getOptions().colors[0]).setOpacity(0).get('rgba')]
]
},
marker: {
radius: 2
},
lineWidth: 1,
states: {
hover: {
lineWidth: 1
}
},
threshold: null
}
},
series: [{
type: 'area',
name: 'USD to EUR',
data: data
}]
});
});
});
you should use the addPoint function in the data series...
here is an example of a chart that updates every second

Hi I am using the Highcharts library to create a bar chart with a cumulative plot line as demonstrated in the jsFiddle below.
CHART DEMO
I am looking to have the cumulative series represented like the red line in the following image (with cumulative values plotted on the right-most axis):
SAMPLE OF DESIRED OUTPUT
As you can see the secondary Y Axis is flipped and is displaying the series index value rather than the actual cumuative values.
Here is the current code:
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Historic World Population by Region'
},
subtitle: {
text: 'Source: Wikipedia.org'
},
xAxis: [{
categories: ['Africa', 'America', 'Asia', 'Europe', 'Oceania'],
title: {
text: null,
}
},
{
opposite:true,
title: {
text: "Cumulative"
}
}],
yAxis: {
min: 0,
title: {
text: 'Population (millions)',
align: 'high'
}
},
tooltip: {
valueSuffix: ' millions'
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -40,
y: 100,
floating: true,
borderWidth: 1,
backgroundColor: ((Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF'),
shadow: true
},
credits: {
enabled: false
},
series: [{
name: 'Year 1900',
data: [133, 156, 947, 408, 6]
}, {
name: 'Year 2008',
data: [973, 914, 4054, 732, 34]
}, {
name: 'Cumulative',
xAxis:1,
type:"spline",
data: [34, 732, 914, 1973, 4054]
}
]
});
How can I correct this in order to plot the series as intended?
Thanks!
What you can do is after loading add a new series based on the sum of the 2 series added at creation:
events: {
load: function () {
var s1900 = this.series[0].data;
var s2008 = this.series[1].data;
var newData = [];
if (s1900.length == s2008.length) {
for (var i = 0; i < s1900.length; i++) {
newData.push(s1900[i].y + s2008[i].y);
}
}
this.addSeries({
name: 'Cumulative',
xAxis: 0,
type: "spline",
data: newData
});
}
}
I am not sure why you want this on the opposite xAxis or why your curve in the linked image you supplied is not really the cumulative unless that is not what you really want. See live demo.
Note you are going to have to handle cases where not all points have a value or if one category is not in both series, etc etc etc.
Revised answer.
Assuming you want to have the same categories on the alternate xAxis and do not want to share the same yAxis you can do:
...
xAxis: [{
categories: ['Africa', 'America', 'Asia', 'Europe', 'Oceania'],
title: {
text: null
}
}, {
categories: ['Africa', 'America', 'Asia', 'Europe', 'Oceania'],
opposite: true,
title: {
text: null
}
}],
yAxis: [{
min: 0,
endOnTick: false,
title: {
text: 'Population (millions)',
align: 'high'
}
}, {
min: 0,
opposite: true,
reversed: true,
endOnTick: true,
title: {
text: 'Cumulative Population (millions)',
align: 'high'
}
}],
...
This sets it up so that you have identical xAxis categories (other ways to do this). See new demo.
