I have created a basic boxplot using highcharts and it shows me the values for maximum, max quartile, median, min quartile and minimum when I hover the mouse over the box plot. I want to somehow display these values in the plot itself beside each of the lines.
I checked out the api and found that "dataLabel" would help but this is not supported for the boxplot. Could someone enlighten me on how to achieve this?
Thanks.
Not possible out of the box, but as mentioned by Steve Gu achievable by scatter. You can even ignore the formatter and disable the marker alltogether:
{
series: [
{
type: 'scatter',
tooltip: {
enabled: false
},
dataLabels: {
format: '{key}',
enabled: true,
y: 0,
},
data: [{ x: 0, y: 975, name: '975'}],
marker: {
enabled: false,
}
}
]
}
just disable marker and set format to key.
Add another data series, which is a type of "Scatter" and apply the data labels to this series using Marker. The trick is to use the same fill color as your background color and 0 line width so the marker will not be visible and only the label will be shown.
{
name: 'Outlier',
color: 'white',
type: 'scatter',
data: [ // x, y positions where 0 is the first category
{
name: 'This is my label for the box',
x:0, //box index. first one is 0.
y:975 //it will be bigger than the maximum value of of the box
}
],
dataLabels : {
align: 'left',
enabled : true,
formatter : function() {
return this.point.name;
},
y: 10,
},
marker: {
fillColor: 'white',
lineWidth: 0,
lineColor: 'white'
}
}
Unfortunately this option is not supported, only what you can do is use renderer to add custom text inside chart, but I'm aware that it can be not comfortable solution. http://api.highcharts.com/highcharts#Renderer.text()
Obviosuly you can reqest your suggestion in our user voice system http://highcharts.uservoice.com/

Here I am getting gradient color at top of the chart area by reversing y-Axis. check the image below .
yAxis: {
reversed: true,
showFirstLabel: false,
showLastLabel: true
}
I don't want to reverse the y-Axis, if i am reversing the y-Axis my chart also reversed. I want the gradient color which is in top of the chart line without using this Reversed Y-axis. Suggest me to if any other options in highcharts.
Could any one help me to solve this.
I am working live random data. In this case only the area traveled by the data should get the gradient color , empty space other than the data in chat shouldn't get gradient color.
As per #DaMaxContent answer , the output will act like below image.
I don't want that gradient which filled in other area of the chart data. Could you please help me to resolve this.
The break down:
You can use gridZindex and backgroundColor/fillColor properties to produce the desired effect. Only issue is that the grid has to be displayed over graph.
The solution:
DEMO
The code behind it:
chart: {
type: 'area',
backgroundColor: { //<<--that is what you are using as fill color
linearGradient : {
x1: 0,
y1: 1,
x2: 0,
y2: 0
},
stops : [
[0, Highcharts.getOptions().colors[0]],
[1, Highcharts.Color(Highcharts.getOptions().colors[0]).setOpacity(0).get('rgba')]
]
}
},
rangeSelector: {
selected: 1
},
title: {
text: 'AAPL Stock Price'
},
yAxis: {
reversed: false,
showFirstLabel: false,
showLastLabel: true,
gridZIndex: 1000 //<<--grid Z index is used to display grid lines over the graph instead of under it
},
series: [{
name: 'AAPL Stock Price',
data: data,
threshold: null,
fillColor : "#fff", //<<--fill color under the line to simulate effect
zIndex: 1000,
tooltip: {
valueDecimals: 2
}
}]
If you wish to get rid of the marginal color areas, you can get rid off the graphs margin with chart: { [... ,] margin: 0 [, ...] } and then use the container's padding as the graph margin.

To meet the various criteria you have asked for, I would accomplish this by creating a dummy series to create the gradient effect.
Example Result:
In this scenario, you will need to pre-process your data, and you will need to assign a max value for the y axis explicitly.
Example Code:
var max = 0;
var data1 = [...your data array...];
var data2 = [];
$.each(data1, function(i,point) {
max = point > max ? point : max;
});
max = Math.ceil(max * 1.1);
$.each(data1, function(i,point) {
data2.push((max - point));
});
You will then need to assign that max value as your yAxis max proeprty, and you may need to either set endOnTick: false, or otherwise account for the max resolving with your tickInterval:
yAxis: {
max:max,
endOnTick:false
}
Then for your dummy series, define the background color gradient.
We'll also set the showInLegend and enableMouseTracking properties to false so that it doesn't show in the legend or tooltip:
{
data: data2,
showInLegend:false,
enableMouseTracking:false,
fillColor : {
linearGradient : {
x1: 0,
y1: 1,
x2: 0,
y2: 0
},
stops : [
[0, Highcharts.getOptions().colors[0]],
[1, Highcharts.Color(Highcharts.getOptions().colors[0]).setOpacity(0).get('rgba')]
]
}
Fiddle Example:
http://jsfiddle.net/jlbriggs/mcp3trmk/
This ensures that the gradient will always match the data, as requested.
As you can see from this js fiddle you have to add this:
series: [{
name: 'AAPL Stock Price',
data: data,
threshold: null,
fillColor : {
linearGradient : {
x1: 0,
y1: 1,
x2: 0,
y2: 0
},
stops : [
[0, Highcharts.getOptions().colors[0]],
[1, Highcharts.Color(Highcharts.getOptions().colors[0]).setOpacity(0).get('rgba')]
]
},
tooltip: {
valueDecimals: 2
}
}]

Having a chart type line, where I have drawn points on the same point x with y but different, I should bring up the tooltip on the various points, but unfortunately when I pass with the mouse on the chart appears to me only one of the marks painted on the same x, ignoring the other. The graph is on:
enter link description here
I tried, but unfortunately I have not found anything to solve my problem. And 'possible to bring up the tooltip on all points?
Thank you all for the help.

Use scatter serie, instead of line chart.
series: [{
type: 'scatter',
lineWidth: 2,
name: 'Litri Carburante Rimasti',
data: data,
marker: {
enabled: false
},
dataLabels: {
enabled: true,
formatter: function () {
return Highcharts.numberFormat(this.y, 2)
},
color: "#000000"
},
color: colorerifornimento,
}]

Need to draw vertical lines from a desired point rather than starting from 0.
plotLines: [{
color: '#FF0000',
width: 1,
value: 4
}, {
color: '#FF0000',
width: 1,
value: 7
}],
Here is the fiddler link: http://jsfiddle.net/bpswt3tr/4/
My requirement is to draw first vertical line from when y value is 110.2 and 2nd line from when y value is 135.6 instead of starting from zero. i.e above the plot line only. Please suggest how can I achieve this? Thanks.
Considering the documentation it is unlikely that HighCharts supports this by default, as you are only allowed to associate a value of the current axis with the line.
You might need a preprocessing step that inverts you function to get the appropriate X values. Something like:
invert(data, Y) -> list of X values with data[X] = Y
You can do this on the chart.events.load call. If you know these are the points you want to add marker elements to then it is fairly straightforward. You first get the current max label value for the yAxis. Then you add a series to the chart with the starting point being your series' value and the second point being the max viewable yAxis value. Then do the same for the second point you want to add a bar to. Then, you need to re-set the yAxis max value to the initial state because highcharts will try to increase the scale to accommodate the new points.
chart: {
events: {
load: function () {
var yMAx = this.yAxis[0].max;
console.log(yMAx);
this.addSeries({
data: [{
x: 4,
y: 110.2,
marker: {
symbol: 'triangle'
}
}, {
x: 4,
y: yMAx,
marker: {
symbol: 'triangle-down'
}
}, ],
showInLegend: false,
color: 'red',
marker: {
enabled: true
}
});
this.addSeries({
data: [{
x: 7,
y: 135.6,
marker: {
symbol: 'triangle'
}
}, {
x: 7,
y: yMAx,
marker: {
symbol: 'triangle-down'
}
}, ],
showInLegend: false,
color: 'red',
marker: {
enabled: true
}
});
this.yAxis[0].update({
max: yMAx
});
}
}
}
Sample demo.
I'm trying to update a point[x,y] in the chart.
What's the problem?
Ok, I chart and its chart series are like this:
series: [
{
enableMouseTracking: false,
name: 'Line1',
type: 'line',
color: '#5d5d5d',
yAxis: 1,
data: [[12000, 55.068493], [15064, 42.842]],
marker: {
symbol: 'circle'
}
},
{
enableMouseTracking: false,
name: 'Line2',
type: 'line',
color: '#5d5d5d',
yAxis: 1,
marker: {
symbol: 'circle'
},
data: [[12000, 57.671527], [16000, 42.620069]]
},{
name: 'TOM',
//type: 'line',
color: '#ff4100',
yAxis: 1,
marker: {
symbol: 'url(icons/tom.png)'
},
data: [
{
id:'tom_point',
color: '#00FF00',
y: fi_variable,
x: tom_variable
}
]
}
Now the thing is that, I'm checking if fi_variable or tom_variable has changed and if its true, update these two variables, and finally update the chart.
I have tried already, some methods like chart.series[0].data[0].update(y = 10); and its working for some points with fixed x,y values, but no luck for the rest of the points.
For Instance I use chart.series[0].data[1].update(y = 10); will work ok,
but this chart.series[0].data[3].update(y = 10); will not work.
1- Is there any way to replace the data[0] from the above code line with an id of a point in our case tom_point ?
Also I've tried this chart.series[0].setData([[tom_variable,fi_variable, 'tom_point']]);
and again it wont working when the point is with an id or without fixed values.
But If I try chart.series[0]data[0].setData([[tom_variable,fi_variable]]); it works but again not on 3rd element (in our case - as shown above) of the series.
I can get the values for this point with the following,
var tomPoint = chart.get('tom_point').y;
but I can't set any x,y values back to chart and update it (the chart).
I have also tried to check if the variables have changed and to redraw the chart with chart.redraw but nothing.
Any Ideas how can I get this to work?
Am I losing something?
Thank you in Advance for your time.
First of all you try to update point (data[3]) which doens't exist in serie. Secondly in case when you update you need to use
chart.series[0].data[1].update(10); or chart.series[0].data[1].update({y:10}); but not yoru figure
if you want to change the x value also then use
chart.series[0].data[0].update({
x: 10,
y: 100
})
this will update both x and y values like in this example http://jsfiddle.net/DCA8W/
Hope this is what you are looking for.
Ok, the solution finally was simple.
I've managed to update the point:
The third element in the series with the name TOM corresponds to
chart.series[2].
{ // chart.series[2]
name: 'TOM',
//type: 'line',
color: '#ff4100',
yAxis: 1,
marker: {
symbol: 'url(icons/tom.png)'
},
data: [
{
id:'tom_point',
color: '#00FF00',
y: fi_variable,
x: tom_variable
}
]
}
So in order to update [x,y] values of this point, you have to do it like that:
// TOM Point
`chart.series[2].data[0].update({x:var_x, y:var_y});`
