I want to create a linechart with HighCharts that has a plotband along every point of the line. Like so: https://imgur.com/a/WVj7uJb
(They are using HighCharts as well, so it must be possible).
However, I can't seem to manage getting it for every point specific. Whenever I add plotbands, it just draws a band using the highest and lowest point like so: https://imgur.com/a/PZdKIBz
How I currently render the chart (note the plotbands part):
Highcharts.chart('chart', {
chart: {
type: 'line',
},
title: {
text: `${this.variable}`,
},
credits: {
enabled: false,
},
xAxis: {
type: 'category',
title: {
text: "Date"
},
},
yAxis: {
title: {
text: this.unit
},
plotBands: [
{
color: "orange",
from: 12,
to: 14
},
{
color: "orange",
from: 10,
to: 13
} // and so on.
]
},
tooltip: {
headerFormat: `<div>Date: {point.key}</div>`,
pointFormat: `<div>${this.unit}: {point.y}</div>`,
useHTML: true,
},
series: seriesList,
} as any);
So exact example would render a plotband from 10 to 14 along the whole linechart, instead of to different points: one from 12 to 14, and one from 10 to 13.
Any ideas as to how I can accomplish this? I have seen something with 'path', but I can't find anything about it.
Thanks in advance.
In that case, you should use arearange series instead of plotBand.

I am using the Javascript ECharts library for displaying some data in my Angular 2+ app. I see that all the examples have some configuration like the following:
{
xAxis: [
data: ['00:00', '01:15', '02:30', '03:45']
],
series: [
{ name: 'A', type: 'line', data: [300, 280, 250, 260] },
{ name: 'B', type: 'line', data: [200, 120, 700, 290] },
]
}
But my data does not always provide values for all the labels in the x axis. For example, I would need to fit these arrays of custom objects into the chart:
const series1 = [{ label: '00:00', value: 300 }, { label: '02:30', value: 120 }];
const series2 = [{ label: '03:45', value: 890} ];
Of course, I could manually insert null or empty values in all the series so that all of them provide a value for each label in the axis. But I believe there should be a more straightforward way to achieve this in ECharts, as it is quite simple in other chart libraries like Kendo Charts.
Assuming you are working with line chart, below is the solution, anyway it is not that different for other charts, just make sure your xAxis type is category
Your xAxis type should be set to category, and data should be something like this
xAxis: [
type: 'category'
data: [ {name: '00:00'}, ....]
]
your series data should look like this
//dimx , value
const series2 = [['03:45', 890]];
You can use the 'time' format to fit series with different lengths.
Even the series, in this way, can have different lengths.
const colors = ['#5470C6', '#EE6666'];
let option = {
color: colors,
xAxis: {
type: 'time',
splitNumber: 11,
axisLabel: {
rotate: 45,
formatter: { hour: '{hh} : {mm}' },
},
},
yAxis: {
type: 'value',
},
series: [
{
name: 'Precipitation(2015)',
type: 'line',
data: [
['2012-03-01T12:22:33.123', 2.2],
['2012-03-01T12:23:33.123', 5.6],
['2012-03-01T12:24:33.123', 7.9],
['2012-03-01T12:25:33.123', 9.0],
['2012-03-01T12:28:33.123', 7.9],
['2012-03-01T12:30:33.123', 9.0],
['2012-03-01T12:32:33.123', 26.4],
['2012-03-01T12:40:33.123', 28.7],
],
},
{
name: 'Precipitation(2016)',
type: 'line',
data: [
['2012-03-01T12:22:33.123', 2.2],
['2012-03-01T12:23:33.123', 5.6],
['2012-03-01T12:38:33.123', 26.4],
['2012-03-01T12:40:33.123', 28.7],
],
},
],
};
result
Here is an Echarts column chart:
option = {
xAxis: {
type: 'category',
data: ['Mon','Tue']
},
yAxis: {
type: 'value'
},
series: [{
data: [120],
type: 'bar'
},
{
data: [100],
type: 'bar'
}
]
};
It will display a column chart with two bars, one for each series. ECharts will render it as such:
What I really want is for Mon to be a label for the red bar in the first data series, and Tue to be a label for the blue bar in the second data series. In other words, I want the x label for each item in each series to display, as it would if it were a single series:
This second chart is the way I want it to display except I want the Tue bar to display in blue as it would if it were in another series.
In my real-life scenario, I expect there would be only one item per series, so if the solution has something to do with the name of the series as opposed to names/label of the individual items, that would work for me.
Any guidance would be appreciated.
There are at least two ways you can accomplish this.
Use two bar series and barGap:
option = {
xAxis: {
type: 'category',
data: ['Mon','Tue']
},
yAxis: {
type: 'value'
},
series: [{
data: ['-', 120],
type: 'bar',
barGap: '-100%'
},
{
data: [100, '-'],
type: 'bar'
}
]
};
ref: https://echarts.apache.org/en/option.html#series-bar.barGap
Use a single bar series with a customized data item:
option = {
xAxis: {
type: 'category',
data: ['Mon','Tue']
},
yAxis: {
type: 'value'
},
series: [{
data: [
120,
{
value: 100,
itemStyle: {
color: '#324b5b'
}
}
],
type: 'bar'
}
]
};
ref: https://echarts.apache.org/en/option.html#series-bar.data
Either of the above approaches should yield a chart that looks like this:
two vertical bars with different colours

If you see, there are two tooltips. One for the candlestick series and another one for SMA series. I want to merge these two tooltips into one in such a way that in one tooltip after open , high , low , close values. SMA series name and the value should come. I tried to do using tooltip formatter but maybe I am missing something so it is not coming in the way I want.
Have you tried to play with the tooltip.shared and tooltip.split parameters? Here is the code:
tooltip: {
split: false,
shared: true
},
Live example: https://jsfiddle.net/s8m90bjt/

I'm using Highcharts, and I used to be able to get labels on the side. But it's not working now, am I missing something? The red arrow is where I would want the labels like in the following example.
http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/bar-basic/
This is the code I'm using, I add the series in a dynamic way.
credits: {
enabled: false
},
chart: {
type: 'bar'
},
xAxis: {
categories: ['Jan', 'Feb'],
labels: {
enabled: true,
}
},
yAxis: {
min: 0,
max: 100,
title: {
text: 'Score',
align: 'high'
}
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
}
}
});
// Add Series
var detailchart = $('#chart-detail').highcharts();
var categories = new Array;
// Set Chart Title
detailchart.setTitle({text: results[0].category});
$.each(results, function(i, data){
categories.push(data.name);
detailchart.addSeries({
name: data.name,
data: [data.score]
});
});
detailchart.xAxis[0].setCategories(["1", "2"]);
$('#chart-detail').highcharts().reflow();
Results is an array that looks like this (I get it through ajax):
As I understand from your code here, you wish to specify two categories with names 1 and 2 but you are not specifying any data for second category, So the only category that is showing on your chart is 1. Your data array for each series must have elements per each category. For example if you have two category you should consider having two data elements in each series. In this line data: [data.score] you are just specifying one element in data array. Your code should be something like this: (make it dynamic per your need)
$.each(results, function(i, data){
categories.push(data.name);
detailchart.addSeries({
name: data.name,
data: [data.score, 40], //40 is some data for your second category.
});
});
Demo: http://jsfiddle.net/u6crkatv/
Only what you need is use 4 series, each of them with single data point.
series: [{
name: 'Year 1800',
data: [107]
}, {
name: 'Year 1900',
data: [138]
}, {
name: 'Year 2008',
data: [973]
},{
name: 'Year 20098',
data: [973]
}]
