I currently was looking at How do I put Icons in the y Axis for a Dynamic Highcharts chart?
My question is similar but here, I want to return a triangle symbol without an image.
I want the axis to have a triangular symbol on a specific point
image of what i am trying to establish
i have a formatter
chartOptions.Xaxis.labels.formatter = function() {
if (<some point>) {
return <triangle symbol>
}
}
You can add a new dummy series to render this point:
{
marker: {
symbol: 'triangle'
},
enableMouseTracking: false,
color: 'red',
data: [{
x: 3,
y: 0,
}]
}

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'
}
})

Hello Highcharts and stackoverflow,
I would like to make it easy for end users to compare wedgets in a Variable radius pie chart (basically the same as Line to the Y axis on hover but radial). As such, when they hover on a wedge, I would like to draw a "ring" around the circle for easy comparisons. This would be appear/disappear/change based on which point you are hovering on.
(in some ways - like a mix between the visualization of the Variable radius pie chart with the concept of an axis like a Polar/Radar Chart)
Any ideas?
Use column series in polar chart with crosshair:
chart: {
polar: true
},
series: [{
type: 'column',
pointPadding: 0,
groupPadding: 0,
colorByPoint: true,
data: [...]
}],
yAxis: {
crosshair: {
color: 'red',
zIndex: 3
}
}

I have created a graph using highcharts which has 6 series. 3 are column series and 3 are spline series.spline series will collide or go within the column chart so having a requirement to add outline to spline series to have better viewing. Trying to add a border color for the spline series but unable to do. But the same is possible in column chart.If anyone have tried this before for spline series kindly help.
plotOptions: {
series: {
borderColor: '#303030'
}
},
this bordercolor is working for column but not in spline series
column chart

would like to have border for the below series
http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/plotoptions/series-datalabels-box/
There is no such feature in Highcharts to set line border, but all is not lost.
You can achieve the effect you want, by adding new "fake" series basing on every line series, and set a couple of parameters.
Best place (in code) to do that would be the chart.events.load function, so there just find all series with line type:
chart: {
events: {
load() {
var series = this.series.filter(elem => elem.type === 'line')
}
}
}
Then, iterate on all the series found, and create new one so that it would have color: [color_you_want], the same data and marker.symbol, increased lineWidth as well as marker.radius, won't be accessible by mouse and not visible in legend, just like below:
chart: {
events: {
load() {
var series = this.series.filter(elem => elem.type === 'line')
series.forEach(series => {
this.addSeries({
data: series.userOptions.data,
showInLegend: false,
color: '#000',
enableMouseTracking: false,
zIndex: -9999,
marker: {
symbol: series.symbol,
radius: series.options.marker.radius + 1
},
lineWidth: series.options.lineWidth + 2
})
})
}
}
}
Hope, it helps you.

Is there a way to show plotlines even when the associated axis has visible: false? Is seems that hiding the axis also hides the plotlines.
More details...
I'm drawing a diagram of a day, like this:
I simply want to add a vertical line at certain times, line the "Now" time, etc.
If I do that using a plot line, then the axis shows up too:
I definitely do not want the axis to show.
My plan now is to draw my own line on the chart using render.rect or render.path. Is there another option?
I found a relatively trivial solution... just hide it with css:
.highcharts-xaxis {
display: none;
}
and in js:
xAxis: {
type: 'datetime',
labels:{
enabled: false
}
}
You can extend Highcharts by wrapping the method responsible for redrawing an axis.
Highcharts.wrap(Highcharts.Axis.prototype, 'redraw', function(p) {
p.call(this);
console.log(this);
var axis = this,
each = Highcharts.each,
options = this.options;
// move plot lines and bands
if (!axis._addedPlotLB) { // only first time
each((options.plotLines || []), function(plotLineOptions) {
axis.addPlotBandOrLine(plotLineOptions);
});
axis._addedPlotLB = true;
}
each(this.plotLinesAndBands, function(plotLine) {
plotLine.render();
});
});

The solution above is not very elegant, though. Much better ways to do it is using Renderer or hide particular axis elements (labels, ticks, etc.).
Depending on what you need from plot lines functionality, using renderer requires to do some calculations.
var customPlotLines = [{
value: 5,
color: 'red',
width: 3
}, {
value: 10,
color: 'yellow',
width: 3
}]
function renderPlotLines() {
var axis = this.xAxis[0],
top = axis.chart.plotTop,
bottom = top + axis.chart.plotHeight,
path = [
'M', null, top,
'L', null, bottom
];
if (!this.customPlotLines) {
this.customPlotLines = customPlotLines.map(plotLine => {
return this.renderer.path([]).add();
});
}
this.customPlotLines.forEach((plotLine, i) => {
var opt = customPlotLines[i];
path[4] = path[1] = axis.toPixels(opt.value);
plotLine.attr({
d: path.join(' '),
'stroke-width': opt.width,
stroke: opt.color
});
});
}
Hook into load/redraw event, so the elements will resize.
chart: {
zoomType: 'xy',
events: {
load: renderPlotLines,
redraw: renderPlotLines
}
},

I have a very simple example using Highcharts which uses "datetime" on one axis and categories on the other. It renders with no points and does not show the categories labels at all. I'm wondering now if you can't use that combination of types. Here is the code:
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container'
},
xAxis: {
type: 'datetime'
},
yAxis: {
categories: ['p1', 'p2']
},
series: [{
type: 'scatter',
data: [
{
name: 'Deliv1',
x: Date.UTC(2011,0,1),
y: 'p1'
},
{
name: 'Deliv2',
x: Date.UTC(2012,0,1),
y: 'p2'
}
]
}]
});
The answer to my problem was given on the highcharts forum. I thought I'd report back here what the solution was. I was errantly using y: 'p1' and y: 'p2' for values on the points. The y values actually are the indexes of the categories. Here is the updated code which works:
data: [
{
name: 'Deliv1',
x: Date.UTC(2011,0,1),
y: 0
},
{
name: 'Deliv2',
x: Date.UTC(2012,0,1),
y: 1
}
]
It's possible but you'll need to pretend the y values are numeric.
Probably by having an array with the actual Y-value and a number (maybe index) then the point's y value to the number and for the y-axis settings add the label's formatter to return the actual y-value based on the value.
You'll also need to adjust the min, max, interval and if you're using tooltips add a similar formatter to get the y-value.
(If I get more time, I'll try to create an example).
