I change the color and radius of my spline's marker as soon as it crosses a certain value by using point.update however now I am aggregating the data using dataGrouping and I have lost that ability. How can I color the aggregated data point?
Currently it is not possible to update grouped points. Please check a thread in this github isssue: https://github.com/highcharts/highcharts/issues/5147
However, you can use attr method directly on SVG point elements:
chart: {
events: {
load: function() {
var points = this.series[0].groupedData;
points.forEach(function(point) {
if (point.y > 30) {
point.graphic.attr({
width: 8,
height: 8,
fill: 'red',
translateX: -2
});
}
});
}
}
}

This is the link to the fiddle
https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/plotoptions/box-plot-styling/
Below are the plotOptions.
plotOptions: {
boxplot: {
boxDashStyle: 'Dash',
fillColor: '#F0F0E0',
lineWidth: 2,
medianColor: '#0C5DA5',
medianDashStyle: 'ShortDot',
medianWidth: 3,
stemColor: '#A63400',
stemDashStyle: 'dot',
stemWidth: 1,
whiskerColor: '#3D9200',
whiskerLength: '20%',
whiskerWidth: 3
}
}
This boxplot shows high and low values in green color. In my case I need to change the high value(Q1) color in red and low value color in green.
How can I do this.?
Thank you
Currently it's not possible in Highcharts by default - related github issue: https://github.com/highcharts/highcharts/issues/6796
Currently each box is a single SVG shape and a border is applied by
stroke parameter which cannot be "separated" for smaller edges. As a
result, you can apply only single color.
Your goal requires a rebuild core of boxplot, so we cannot threat it as a bug, but feature request.
As a workaround you can render custom paths to cover one of the existing whiskers, for example:
events: {
render: function() {
var series = this.series[0],
attr,
paths;
series.points.forEach(function(point) {
paths = point.whiskers.d.split('M');
attr = {
d: 'M' + paths[1],
'stroke-width': 2,
stroke: 'red'
};
if (point.customHigh) {
point.customHigh.attr(attr);
} else {
point.customHigh = this.renderer
.path()
.attr(attr)
.add(series.group);
}
}, this);
}
}

I am trying to create a chart somehow similar to expertoptions' by using Highcharts, however I can't find solution to adding a custom marker to the line, I have tried doing something like:
var myCircle = myChart.renderer.circle(x,y,20).attr({
fill: '#d3d7de'
}).add(circlePointGroup);
var circlePointGroup = myChart.xAxis[0].renderer.g().attr({
translateX: 2000,
translateY: 2000
}).add();
but ended up being a floating static shape, I have here the fiddle, Any help would be appreciated. I have hard time reading their documentation :/
I think that a better approach might be adding this point as a scatter series - that keeps the point in the move while adding new points to the main series. Using renderer.circle renders circle in a static position.
Demo: https://jsfiddle.net/BlackLabel/Lpfj4stx/
var betWindowInterval = setInterval(function() {
myChart.xAxis[0].removePlotLine('markerLineX');
myChart.yAxis[0].removePlotLine('markerLineY');
myChart.series.forEach(s => {
if (s.options.id === 'customPoint') {
s.remove();
}
})
clearInterval(betWindowInterval)
}, 2000);
myChart.addSeries({
type: 'scatter',
data: [{x: lastPointY.x, y: lastPointY.y}],
id: 'customPoint',
marker: {
fillColor: 'red',
radius: 5,
symbol: 'circle'
}
})

In Highcharts, there is a possibility to shift the y-Axis labels into the plot-area with
yAxis: {
labels: {
align: 'left',
x: 0,
y: -2
}
}
With this setting, the labels are covered by the lines, data-labels and so on.
Is it possible to draw the horizontal grid lines across the yAxis-Label-Area without making the xAxis and the series start there. The wished behavior is indicated with the black lines in the image below.
The simplest solution is to adjust the xAxis, for example:
xAxis: {
min: -0.5
}
Live demo: http://jsfiddle.net/BlackLabel/qnayxb04/
API: https://api.highcharts.com/highcharts/xAxis.min
If you want to have more control over the lines, you can use setAttribute to edit the path element:
chart: {
events: {
load: function() {
var gridLines = this.yAxis[0].gridGroup.element.children,
i,
path;
for (i = 0; i < gridLines.length; i++) {
path = gridLines[i].attributes.d.nodeValue;
path = 'M 40' + path.substr(4);
gridLines[i].setAttribute('d', path)
}
}
}
}

Is there a way to have a point specific positionning of the xAxis labels ?
I am using a waterfall chart and for some bars I would like the label to appear directly under the bar like below :
I have found the following code in the xAxis plotOptions but at this point I don't see how I can acces the info on the bottom of the chart.
xAxis: {
labels: {
y:-100 //label's y position
}
},
You can use point dataLabels to achieve such result:
dataLabels: {
crop: false,
overflow: 'none',
verticalAlign: 'bottom',
format: 'label1',
y: 20
}
Live demo: https://jsfiddle.net/BlackLabel/71jtp5mf/
API Reference: https://api.highcharts.com/highcharts/series.waterfall.dataLabels
Another way is to create your own custom function to position the xAxis labels, for example:
events: {
load: function() {
var chart = this,
point;
Highcharts.objectEach(chart.xAxis[0].ticks, function(tick) {
if (!tick.isNewLabel) {
point = chart.series[0].points[tick.pos];
tick.label.attr({
y: point.plotY + chart.plotTop + point.shapeArgs.height + 15
})
}
});
}
}

I know it's possible to put pie chart labels either inside or outside the pie by changing plotOptions.pie.dataLabels.distance. I am trying to figure out whether it's possible to change that on a point by point basis:
if slice is smaller than 15%, place labels inside the slice
else place the label outside the slice
Is this possible in Highcharts? Below is one of my attempts, which doesn't work; the plain jsfiddle is here: http://jsfiddle.net/supertrue/q6bQP/
plotOptions: {
pie: {
dataLabels: {
distance: -30,
color: 'white',
formatter: function() {
if (this.y < 15 ) {
this.point.dataLabels.color = 'red';
this.point.dataLabels.distance = 20;
return this.point.name;
} else {
return this.point.name;
}
}
},
This post can helps you to acomplish your work :
Is it possible to position Highcharts dataLabels depending on the value?
$.each(chart.series[0].data, function(i, point) {
// using the value or calculating the percent
if(point.percentage < 30) {
point.dataLabel.attr({y:20});
}
});
This can be achieve using events as well.
Working fiddle : Outside Fiddle
Here if data point is less than five the show labels outside the charts.
chart: {
type: 'pie',
events: {
load: function() {
var series = this.series[0];
setTimeout(function(){
(series.points).forEach(function(point, i){
if (point.y < 5) {
point.update({dataLabels:{distance: 2}});
}
});
}, 200);
}
}
}
