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 have a chart which has part line and part area stacked. In the first part (area) I want to add an inline legend as it is shown in this example (ie where it says Asia)
https://www.highcharts.com/demo/area-stacked-percent
These are the example options but I do not see how to specify that or if this is the default way to show legends in this plot
In my example, I cannot put the legends inside the area part. Tried to add title in yAxis. I also tried to add an annotation but it did not work:
https://jsfiddle.net/hkpna40r/1/
annotations: [{
labelOptions: {
backgroundColor: 'rgba(255,255,255,0.5)',
verticalAlign: 'top',
y: 4
},
labels: [{
point: {
xAxis: 0,
yAxis: 0,
x: Date.UTC(2019, 11, 2),
y: 3
},
zIndex:100,
text: 'Arbois'
}],
}],
You can achieve what you want by attaching a module called series-label and set plotOptions.area.label like that:
plotOptions: {
area: {
label: {
enabled: true,
onArea: false
}
},
line: {
label: {
enabled: false
}
}
}
Note, annotations also work but you have to attach annotations module separately.

I'm creating a HighStock column bar chart. I have enabled the scrollbar using scrollbar: enabled. The scrollbar works fine for smaller datasets, but this dataset has a lot of categories(I've only included half as many as I need). For some reason, after a certain number, the rects for the bar chart won't properly show(or show wrong values) and the xAxis labels display as numbers rather than their actual names. Also, I'm trying to add IDs to each of the bars to add click events, but it only adds IDs to bars that are properly rendered initially. I have also noticed that I can properly add IDs even with a scrollbar to smaller data sets because all of the rect elements are properly rendered. Is there any way to make this scrollbar work for larger datasets?
You'll see what the problem described above looks like in this link:

Highcharts.chart('container', {

}]
});
It happens because the number of points in series is bigger than the default value of the cropThreshold property (more about below, in the API Reference section). As a solution, set the property with the bigger value.

Just started a week ago to learn and use Highcharts. In my application a user selects a key value from a list box and, out of that key an array of values will be retrieved and, used the data to create a multiple series of line graph. In the screenshot below the first series (in light blue color) has the name of CDEP158 and, on the second series (in black color), the series name shouldn't be 'Series 2', it should be CDT158. 'Series 2' for the second series is the issue here.
This is the chart data preparation code which accepts dataChart (result) from jquery post callback function called in a click event.
function prepareChartData(dataChart)
{
var dataSeries = [];
var xTitle;
for (var i = 0; i < dataChart.length; i++) {
var items = dataChart[i];
var xDate = +moment(items.Time);
var seriesData = parseFloat(items.Value);
dataSeries.push([xDate, seriesData]);
xTitle = items.Name;
}
if (aeChart === undefined || aeChart === null)
{
plotChartData(dataSeries, xTitle);
return;
}
aeChart.addSeries({
title: xTitle,
data: dataSeries
});
};
Function that creates a new instance of Highchart and its configuration:
function plotChartData(dataseries, xtitle)
{
aeChart = new Highcharts.Chart({
chart: {
renderTo: 'svgtrendspace',
type: 'line',
zoomType: 'xy',
panning: true,
panKey: 'shift',
plotBorderWidth: 1
},
title: {
text: ''
},
legend: {
layout: 'horizontal',
align: 'left',
itemDistance: 10,
borderWidth: 0,
itemMarginTop: 0,
itemMarginBottom: 0,
padding: 20
},
plotOptions: {
series: {
states: {
hover: {
enabled: false
}
},
dataLabels: {
enabled: false,
format: '{y}'
},
allowPointSelect: false
}
},
xAxis: {
type: 'datetime',
labels: {
rotation: -65,
style: {
fontSize: '9px',
fontFamily: 'Verdana, sans-serif'
}
}
},
yAxis: {
gridLineColor: '#DDDDDD',
gridLineWidth: 0.5
},
series: [{
name: xtitle,
data: dataseries,
tooltip: {
pointFormat: '{series.name}: <b>{point.y}</b><br/>',
valueDecimals: 2
}
}]
});
};
Why is that the first series gets the correct name but on the second one it did not? Is my highcharts configuration wrong? How should I properly configure or format it to address the issue?
I have googled it for similar issues related with multiple series but I couldn't find any similar questions or answers that would help me.
The fact that it works for the first series implies that the issue isn't with your code, but rather is with your init.
Can you put a console.log('Title: ' + xTitle); statement right before you call aeChart.addSeries() in the above function to check on what you are passing in? My suspicion is that the second series is not being passed a title, and that HighCharts is therefore putting in Series2 on its own.
Maybe you should not be setting the value of xTitle in every single iteration of the initial for loop?
I'm trying to create a chart using highcharts that includes both a column series and a scatter series with a custom point marker. The series will contain slightly different sets of data, but will overlap for the most part and will always have the same x-axis values.
I've set it up, but the problem is that it's not lining up perfectly. Some of the scatter series' points are shifted one or two pixels to the left of the corresponding bar.
Any ideas about how to fix this?
{
chart: {
animation: false
},
xAxis: {
tickInterval: 1
},
series: [{
type: "column",
borderWidth: 0,
pointWidth: 20,
name: "col"
},
{
type: "scatter",
states: { hover: { enabled: false } },
marker: { symbol: 'url(symbol.png)' }
}]
}
And here's a screenshot of what's happening:
Indeed it looks like a bug, also with standard markers, so I've decided to report it to our developers https://github.com/highslide-software/highcharts.com/issues/1843
