I am attempting to get the full label displayed in the x axis, but highcharts keeps on cutting it off. I tried using the crop, overflow, and margin options discussed in other posts to no avail. The only option that worked was to make the div height of the chart an absurd size.
$('#da-expulsions').highcharts({
chart: {
type: 'column',
renderTo: 'da-expulsions',
},
data: {
googleSpreadsheetKey: '1Nx8zcIi0ULxytLmra0A9N11-llzJCDVH2-7SbK_k5-U',
startColumn: 0,
startRow: 0,
googleSpreadsheetWorksheet: 19,
},
title: {
text: 'Expulsion rates at campuses with highest expulsion rates over time'
},
yAxis: {
min: 0,
max: 30,
breaks: [{
from: 12,
to: 24,
breakSize: 1
}],
tickInterval: 3,
title: {
text: 'Expulsions Rate (%)'
},
labels: {
formatter: function() {
return this.value + '%';
}
}
},
tooltip: {
valueSuffix: '%'
},
xAxis: {
type: 'category',
title: {
text: 'School'
},
},
});

The "make the div height of the chart an absurd size" is why the truncated view was added. If you hover over the xAxis labels the full text is shown.
If you want to increase the available size for the xAxis labels you can. Another recommendation would be to use a 'bar' format where the xAxis is vertical and then adjust font sizing of the xAxis label although this is not 100% accurate. What is wrong with the ellipsis?
labels: {
useHTML: true,
style: {
fontSize: '8px',
width: '300px'
}
}

I have created a chart using the HighCharts javascript library, the problem I have is that my y-Axis labels are cut by the Y-Axis vertical line. I would like to add more space in the y-axis label gutter area to allow for the labels to be fully visible and so i can add some annotations to the in that area, see image below:
Ideally I would like to add 40px, to the Y-Axis gutter. I have read through the api reference and tried using "yAxis.labels.padding", "yAxis.margin" and "yAxis.offset".
My code is as follows:

Been banging my head around this for while, but I cant seem to figure it out any help would be very much appreciated. Thanks
In Highstock, the yAxis is inverted by default, so aligning the labels is reversed as well.
The only thing you need to change is setting yAxis.labels.align to 'left'.

I need to show some empty space to far right of the chart. To do so I use "overscroll" option (https://api.highcharts.com/highstock/xAxis.overscroll). But if user zoom in chart and pans chart to far right there can be empty space without any part of candlestick chart displayed (https://screencast-o-matic.com/watch/cqnfFq3CII). Please advise is it possible to implement following chart behaviour and how to do so: to keep some part of chart in visible area always, even if "overscoll" option is set and user pans chart to the far right? Thanks!
Here is my code:
var ohlc = JSON.parse(ohlcStringified),
volume = JSON.parse(volumeStringified);
var interval = ohlc[ohlc.length - 1].x - ohlc[ohlc.length - 2].x;
var chart = Highcharts.stockChart('container', {
chart: {
borderWidth: 1,
panning: true,
},
title: {
text: 'Chart'
},
legend: {
enabled: true
},
rangeSelector: {
selected: 1,
enabled: false
},
scrollbar: {
enabled: false
},
xAxis: {
minPadding: 0.2,
overscroll: 50 * interval,
},
yAxis: [{
height: '40%'
}, {
top: '40%',
height: '30%',
offset: 0
}, {
top: '70%',
height: '30%',
offset: 0
}],
series: [{
type: 'candlestick',
id: 'candlestick',
name: 'AAPL',
data: ohlc,
tooltip: {
valueDecimals: 2
},
dataGrouping: {
enabled: false,
}
}, {
type: 'column',
id: 'volume',
name: 'Volume',
data: volume,
yAxis: 1,
dataGrouping: {
enabled: false,
}
}]
});

It's possible, however, it requires some custom logic. It can be achieved using xAxis.events.afterSetExtremes callback where you can check if the current axis minimum is greater than your limit (a value lower than maximum xData value). When it is true, set new axis extremes with your limit as a minimum value. Check the code and demo posted below.
Code:
xAxis: {
minPadding: 0.2,
overscroll: 50 * interval,
events: {
afterSetExtremes: function() {
var chart = this.chart,
xData = chart.series[0].xData,
maxValue = xData[xData.length - 5],
min = chart.xAxis[0].min,
max = chart.xAxis[0].max
if (min > maxValue) {
chart.xAxis[0].setExtremes(maxValue, max, true, false);
}
}
}
}

I have been working on a project that uses highchart to draw multiple line charts. With that, I have already achieved some configuration (eg. x-axis crosshair, fixed tooltip, zooming) for my chart in accordance to the business requirements. As such, one requirement is that when x-axis crosshair moves from left to right (or vice versa) within the plotted chart, the selected values on y-axis and dates and time on x-axis will be displayed in the fixed tooltip.
Example:
Series CDT158 has a value of 100.46 (as shown in Chart 1) on 27 Apr 2017 20:49:48 pm. When I move the x-axis crosshair to the right, it jumps directly to the next point which has a value of 103.47 (as shown in Chart 2) on 27 Apr 2017 20:50:38 pm.
Is it possible when the crosshair passes through the series (from one point to the next point), the y-axis values between 100.46 and 103.47 as well the datetime values on x-axis will be rendered in the fixed tooltip? I also want to display the CDEP158 y-axis values simultaneously in the fixed tooltip. How can I achieve this?

[Chart 2]
This is the Highchart initialization.

let body = this.points.reduce((body, p) => body + `<small><font color="${p.series.color}"><strong>${p.series.name}</strong></font>: <strong>${p.y}</strong></small><br/>`, '');

}]
});
I'm pretty sure that this can be achieved through Highcharts but, my limited knowledge and experience in Highchart stops me to figure it out.
I have posted a sample fiddle that illustrate the above scenario.
Any help is greatly appreciated.
I've been asked to do this kind of graph (40,9% and 16,4% are examples, they should indicate something like -6% and 9%):
Any idea on how I can get that kind of result, using a javascript library, if possible (but it is not a must) Highcharts?
Thanks
It's possible with HighCharts, Documentation
e.g.
$(function () {
data = [{
valSecond: 25,
valFirst: 62.5
}];
// Build the data arrays
var secondData = [];
var firstData = [];
for (var i = 0; i < data.length; i++) {
// add second data
secondData.push({
name: "Second",
y: data[i].valSecond,
color: "#00FF00"
});
// add first data
firstData.push({
name: "First",
y: data[i].valFirst,
color:'#FF0000'
});
}
// Create the chart
$('#container').highcharts({
chart: {
type: 'pie'
},
title: {
text: ''
},
plotOptions: {
pie: {
animation: false,
shadow: false,
center: ['50%', '50%']
}
},
tooltip: {
valueSuffix: '%'
},
series: [{
name: 'second',
data: secondData,
size: '30%',
startAngle: 270,
endAngle: 360,
innerSize: '20%'
}, {
name: 'first',
color:'#FFFFFF',
data: firstData,
size: '80%',
startAngle: 0,
endAngle: 225,
innerSize: '60%',
}]
});

In the highcharts you can adapt donut chart http://www.highcharts.com/demo/pie-donut, remove connectors, set useHTML for dataLabels and rotate by css / rotation SVG element. Missing elements can by added by renderer.
$(function () {
$('#container').highcharts({
chart: {
showAxes : true,
type: 'line',
marginRight: 130,
marginBottom: 25
},
tooltip: {
crosshairs: [true],
shared : true
},
title: {
text: '',
x: -20 //center
},
subtitle: {
text: '',
x: -20
},
xAxis: {
type :'datetime',
tickInterval : 12*30*24*3600* 1000,
min : Date.UTC(2011, 0, 1),
max : Date.UTC(2020, 0, 1),
label : {
align : 'left'
}
},
yAxis: {
title: {
text: 'PRICE Rs. / SQ.FT.'
},
lineWidth: 2,
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
series: [{
data:[2165,1831,2798,2200,2237,2799,2400,2500,2865,2850]
}]
});
});
My x-axis having Years and data series having information which i want to show on Y axis.
When i remove the interval from 2010 to 2022 i . e comment min and max option highcharts draws a graph starting from 1970 , but no points afterwards.
http://jsfiddle.net/R8kx7/3/ here is the link
Based on your comments to #SteveP answer, if you don't want to explicitly pair x values to each y for each series, use the plotOptions.series pointStart and pointInterval properties.
plotOptions: {
series: {
pointStart: Date.UTC(2011, 0, 1),
pointInterval : 12*30*24*3600* 1000
}
},
series: [{
data:[2165,1831,2798,2200,2237,2799,2400,2500,2865,2850]
}]
Updated fiddle here.
Although you are specifying min and max, your data has no x values specified, so it is assuming that the date time values are starting at 0. There are several ways to render the chart you want.
Firstly, you could specify x values in your data points e.g.
{x:Date.UTC(2011, 0, 1),y:2165}
Another way is to not use a datetime axis type, and just specify the categories you want in the x-axis:
categories:["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"]
The second option is probably a bit simpler http://jsfiddle.net/K6xxz/
