It seems that the options startOnTick, and endOnTick have no effect on a boxplot. Is there anyway to align the outermost ticks to the graph edge with a boxplot?
xAxis: {
startOnTick: true,
endOnTick: true,
min: -1,
max: 6,
},
I have tried adding most combinations of minPadding/maxPadding, tickmarkPlacement: between/on, and manually setting ticks with tickPositioner without any luck. The only workaround I have is to shrink min/max so the padding fixes itself. I would prefer a better solution, because this workaround becomes very ugly for dynamic data.
Here is the fiddle demo demonstrating the problem and another with the workaround. Again, is there any way to align the outermost ticks to the graph edge with a boxplot?
Looking into this led me to these comments buried in parts/Axis.js.
if (!axis.single) {
// minPointOffset is the value padding to the left of
// the axis in order to make room for points with a
// pointRange, typically columns. When the
// pointPlacement option is 'between' or 'on', this
// padding does not apply.
minPointOffset = Math.max(
minPointOffset,
isString(pointPlacement) ? 0 : seriesPointRange / 2
);
// Determine the total padding needed to the length of
// the axis to make room for the pointRange. If the
// series' pointPlacement is 'on', no padding is added.
pointRangePadding = Math.max(
pointRangePadding,
pointPlacement === 'on' ? 0 : seriesPointRange
);
}
The issue is caused by the point padding and probably occurs on any column style plot. The padding will be ignored if pointPlacement is set to 'on' or 'between' on the series.
series: {
type: 'boxplot',
pointPlacement: 'on',
data: ...
}
Here is the working fiddle.

I'm trying to change the size of a column in a heatmap. I can use the colsize to set the width of the border, but i'd like to change the width of the entire column. Is this possible?
Here's a JS fiddle example.
http://jsfiddle.net/8b9410om/
The Total column I would like to change to the same size at the border that you can see around it
You can use endOnTick and pointPlacement properties:
xAxis: {
...,
max: 1.25,
endOnTick: false
},
series: [...,
{
colsize: 0.25,
pointPlacement: -1.5,
...
}
]

I have a type area chart, with minor grid lines and a datetime xAxis. data is feed through an array of y values, and I got to render xAxis labels depending on the data length successfully.
My issues are:
the chart has a unwanted padding on the X axis
the markers don't align with their labels
Check it:
Here's a working fiddle: https://jsfiddle.net/fernandaparisi/e07q32ay/53/
I noticed that if I remove all the max, min, tickInterval, pointStart and pointInterval properties the markers are aligned correctly, but the chart doesn't expand its full available width.
margin and spacing chart properties seem to affect the chart as a whole, and not the plotted area.
Any thoughts?
The padding is caused by combined tickInterval and endOnTick: true, to remove it just disable endOnTick.
To position the labels in a different way use align, x and y properties.
xAxis: {
labels: {
align: 'center',
y: 30,
formatter: function() {
return Highcharts.dateFormat('%e %b', this.value);
},
rotation: -45
},
title: undefined,
type: 'datetime',
min: lastSunday - (weekLength * (data.length - 1)),
max: lastSunday,
tickInterval: weekLength,
endOnTick: false,
minorTickInterval: weekLength
}

Please look at JSFIDDLE. Here the bars overlap each other. How to prevent this by resizing the bar width dynamically.
If happens because you set bar width with fixed value. If you want bars to take all available place for width, instead of using pointWidth, set pointPadding to 0, groupPadding to 0 and borderWidth to 0.

Or you can use scrollbar using highstock.js
xAxis: {
categories: ['First', 'Second', 'Third', 'Fourth', 'Fifth', 'sixth', 'seventh'],
allowDecimals: false,
min: 0,
max: 4,
scrollbar: {
enabled: true
},
},

I need to align table with highcharts, but chart has irregular padding on the edges, it's based on percentage, I guess.
I would like 30 to stick to the left edge of chart (close to 3) or set it distance manually in pixels. How can I do that in highcharts?
Based on #SebastianBochan suggestions, this is complete solution
xAxis:
startOnTick: true
endOnTick: true
minPadding: 0
maxPadding: 0
Try something like this:
yAxis: {
offset: -15
},

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
}
