I am currently working on a specific type of chart and I am trying to achieve the following behavior for example :
As you can see there's a gap between the series last point and the xAxis max value and the reason for this is i wanna have a fix max value and load the daily values of a specific currency as the day passes by. So for example in the morning this chart would be empty and by 18:30 it would be filled.
In my mock example i have the current chart:
and when I try to set a new xAxis max value ( i also tried softMax) to a future day (using epoch converter for unixtimestamp) i am getting this:
and i set the max by doing :
return {
endOnTick: false,
max:1631962355,
tickLength: 2,
gridLineColor: '#b9b9b9',
gridLineWidth: 0,
tickColor: '#808080',
labels: {
style: {
color: '#b9b9b9',
},
x: 0,
y: 12,
format: '{value:%d.%b}',
},
visible: true,
};
}
UPDATE
After implementing your response I get an even weirder behavior. I get the same initial start I had before (no difference) but now if i click and drag it to the right I go from this :
to this:
and If i click and drag it to the left, into this:
The transformation happens without animation, neither by wathching the drag and move motion happen. It just instantly transforms after i drag my cursor pointer for a while towards the sides i mentioned above
You need to use milliseconds instead of seconds:
xAxis: {
max: 1631962355000,
...
}

I've implemented a Gantt chart that contains some Gantt long bars and their time period is usually more than a couple of months, moreover, the xAxis of the chart shows years and months as you can see below gif. XAxis's tick-interval should change automatically when I change the range of the Gantt period, but it doesn't!
The desired way is that if I change the time range to a month or smaller, xAxis's tick-interval should change to month/week or month/day.
xAxis: {
maxPadding: 0,
max: Date.UTC(2024, 07, 16),
plotLines: [
// some lines
]
}
Ticks on the xAxis are calculated based on the provided data.
When your data range is wide, the ticks also tend to cover a wider period of time. To change default behaviour you might set the tickInterval inside the afterSetExtremes function with the use of the update method.
Inside you might specify some conditions like for example visible range.
events: {
afterSetExtremes: function(e) {
if (this.chart.xAxis[1].max - this.chart.xAxis[1].min < 36e8) {
this.update({
tickInterval: 36e7
})
} else {
this.update({
tickInterval: undefined
})
this.chart.xAxis[1].update({
tickInterval: undefined
})
}
}
}

I've developed a bunch of bar charts in HighCharts cloud with positive and negative values.
First question:
is it possible to have the xAxis appear at the 0 line (not at the bottom of the chart)?
What I've done so far is offset the xAxis so it's placed on the 0 line, which kinda works but I was hoping for a better solution. The other method I was think was to use plotLines code on the yAxis, but I don't get the ticks:
plotLines: [{
color: '#010101',
width: 2,
value: 0,
zIndex: 5
}],
Second question:
is it possible to have the tick marks to appear between each bar, and not just the bars that have an xAxis label?
This is what's rendering for me at the moment, and I'm trying to get a tick between all the bars while showing the same number of labels https://cloud.highcharts.com/show/cLtfEDClS
First question:
You can merge this configuration into chart options in Cloud’s custom code section:
chart: {
events: {
load: function() {
var yAxis = this.yAxis[0];
this.xAxis[0].update({
offset: -yAxis.toPixels(Math.abs(yAxis.min), true)
});
}
}
},
Demo: http://jsfiddle.net/BlackLabel/6712zrod/
It automatically positions x axis so that it works as y = 0 line.
Second question:
Try setting X Axis[0] > Labels > Step to 1.
API reference: https://api.highcharts.com/highcharts/xAxis.labels.step
Explanation from Docs:
To show only every n'th label on the axis, set the step to n. Setting the step to 2 shows every other label.
By default, the step is calculated automatically to avoid overlap. To prevent this, set it to 1. This usually only happens on a category axis, and is often a sign that you have chosen the wrong axis type.
i have a highchart with 4 series. I also only set the min value for each y-axis to 0 cause there arent any negative values possible. now highchart is calculating the max value by itself what is nice BUT i need this for each series itself. The reason is that i have 2 series with very high values from the range up to 5000 and the other two values are relativ small from 0 to 50.
The max value highcharts calculates is used for all four series - so the chart looks like this:
As you can see you can only see the two high value series - the other two arent really visible at the bottom of the chart.
When i disable the two series with the high values the chart looks nice for the other two values:
is there any flag i can use so highchart will calculate the max value / scale per series? Or have i really calculate it by myself - also on zoom and so on.
I found this: https://github.com/highcharts/highcharts/issues/4248
But i thought thats some basic functionality with is needed very often so there has to be something..
greetings
Maybe it would be better to use logarithmic axis type? Your chart would have only one axis adjusted to much difference between the values of series points. When it comes to differences between units of measurement, always you can set the different tooltip.pointFormat definition for specific series.
Highcharts.chart('container', {
title: {
text: 'Logarithmic axis demo'
},
yAxis: {
type: 'logarithmic',
},
series: [{
data: [1, 20, 30, 22, 16, 32, 45, 24, 11, 2],
pointStart: 1,
tooltip: {
pointFormat: '<b>{point.y} km/h</b>'
}
}, {
data: [4500, 3450, 4242, 2348, 5216, 3212, 4564, 3128, 5256, 4512],
pointStart: 1,
tooltip: {
pointFormat: '<b>{point.y} kW/h</b>'
}
}]
});

I'm trying to display a solid gauge with a "strange" max value, that is 96 (hours).
I'read that max and min value are elaborated by highcharts to set ticks, ranges etc but I don't understand why I can't display such a value or even other rounded values like 90 below 100.
Any idea?
The problem may be that the chart is generating a default tick interval e.g. 10, which adds up to 100.
You may be able to get what you want by specifying a tickerInterval which divides into 96 (e.g. 8).
yAxis: {
min: 0,
max: 96,
tickInterval:8,
http://jsfiddle.net/Vn4My/
You can use any max value, only thing is you should divide it by 1000 to get the tickInterval value, for example:
yAxis: {
min: 0,
max:96,
tickInterval:(96/1000),
},
Working example: http://jsfiddle.net/NareshChennuri/whuu5qbt/
To get the exact custom max value :
tickPositioner: function() {
return [this.min, this.max];
},
min: 0,
max: 6924,
refer this issue on github
Try This I am also facing the same issue but I resolve that issue this solution may be useful for you.
yAxis: {
min: minData,
max: maxData,
tickPositions: [minData, maxData]
},
Add tickPositions: [minData, maxData];

I hope this is enough.

I'm outputting a series of highcharts on a page. In some instances, all data for the specified time period may come back with 0 values.
In such a case, the chart looks like this: http://jsfiddle.net/charliegriefer/KM2Jx/1/
There is only 1 y-Axis label, 0, and it's in the middle of the chart.
I'd like to force that 0 value for the y-Axis to be at the bottom of the chart, which would be consistent with other charts on the page that do have data.
Have tried various yAxis properties, such as "min: 0", "minPadding: 0", "maxPadding: 0", "startOnTick: true".
Seems it should be pretty straightforward, but I'm at a loss :(
Relevant yAxis code:
yAxis: {
min: 0,
minPadding: 0,
startOnTick: true,
title: {
text: ""
}
},
I've found another (and very simple) solution:
You can set y-axis minRange property:
yAxis: {
...
minRange : 0.1
}
This makes Highcharts render yAxis min and max values when all data is 0.
UPDATE:
Highcharts 4.1.9 fix also needs:
plotOptions: {
line: {
softThreshold: false
}
}
updated js fiddle
Only way I could get it to show it "correctly" was by also providing an yAxis max value. I think this is a HighCharts issue when you provide no data elements with a y-value. It draws the best chart it thinks it can.
I had also posted this to the HighCharts forum, where I got a response that seems to work. Unfortunately, it will involve me doing some pre-processing of the data prior to rendering the charts in order to check for all "0" data values... but it'll work. Just wish there was something more "built-in" to HighCharts.
So after summing up the "y" values, if I get 0, the y-axis properties should look like this:
yAxis: {
minPadding: 0,
maxPadding: 0,
min: 0,
max:1,
showLastLabel:false,
tickInterval:1,
title: {
text: ""
}
}
See: http://jsfiddle.net/KM2Jx/2/
The keys seem to be the "max" and "showLastLabel" properties.
Here is a fix I came up with that doesn't require any preprocessing of the data and just let highcharts do it, like it used to before the update. http://jsfiddle.net/QEK3x/
if(chart.yAxis[0].dataMax === 0)
{
chart.yAxis[0].setExtremes(0, 5);
}
You only need to check the first series axis, as if the first one is not 0 then the problem won't occur. I might submit a pull request for this to high-charts, though I kinda feel like they intended for this functionality for some reason.
Since Highcharts 5.0.1, you can also use softMax.
softMax: Number
A soft maximum for the axis. If the series data maximum is greater than this, the axis will stay at this maximum, but if the series data maximum is higher, the axis will flex to show all data.
yAxis: {
min: 0,
softMax: 100,
...
}
Here is an example with a column chart : http://jsfiddle.net/84LLsepj/
Note that currently, in Highcharts 5.0.7, it doesn't seem to be working for all types of charts. As you can see in this other jsfiddle, it doesn't work with line chart.
Just add "min" option
yAxis: {
min: 0
}
For Highcharts 5.x.x, you should be able to just specify:
yAxis: {
softMin: 0,
softMax: 1,
};
This won't work for line chart, which requires that you also set minRange in the same config object as above. Experiment with different values, since defining for example minRange: 6, created a range on yAxis between 0 and 4.
minRange : 1 or whatever you feel so to be displayed in fractions of
softMax : 100 or whatever you feel so
yAxis: {
minRange : 1,
softMax: 100
}
