In this Highcharts column chart the user can drill down by clicking on the column.
This works fine, however all the data, including the data of the drilled column, needs to be available when the chart is firstly created.
What I need is to capture the drilldown event click and populate the chart with that information, sending the data only when the user clicked on a specific column. Is this possible?
Yes, it is possible and simple. You need to use drilldown event callback function, call API request in it and use addSeriesAsDrilldown method - as in the example below:
chart: {
type: 'column',
events: {
drilldown: function(e) {
if (!e.seriesOptions) {
var chart = this,
drilldowns = {
...
},
series = drilldowns[e.point.name];
// Show the loading label
chart.showLoading('Simulating Ajax ...');
setTimeout(function() {
chart.hideLoading();
chart.addSeriesAsDrilldown(e.point, series);
}, 1000);
}
}
}
}

I have more than one chart in one page, all of them uses same data but in different chart types.
I would like to change all of their time with only one navigator on the top. like using it as a datepicker input, how can i achieve that?
Use afterSetExtremes event callback function and apply the same extremes on the rest charts:
xAxis: {
events: {
afterSetExtremes: function(e) {
var min = e.userMin,
max = e.userMax;
chart1.xAxis[0].setExtremes(min, max, true, false);
chart2.xAxis[0].setExtremes(min, max, true, false);
}
}
}

Building upon my previous question here SO
I want to reach this desired affect on mouse hove. Draw multiple series like so
Could you please recommend highstock best practice for the same?
Thanks
You can add an additional series in the first mouseOver event and then update its data. For example:
series: [{
data: [...],
point: {
events: {
mouseOver: function() {
var chart = this.series.chart;
if (!chart.series[1]) {
chart.addSeries({
data: additionalData[this.index].slice()
});
} else {
chart.series[1].setData(
additionalData[this.index].slice()
);
}
}
}
}
}]

I have created my own master-detail chart following the Highcharts docs and this example: https://www.highcharts.com/demo/dynamic-master-detail
Eveything works fine but I would like to add a feature: When the chart is loaded the last 50 data points should automatically be selected in the master chart and thus shown in the detail chart.
I tried to manually trigger the selection event but it did not work out. Any idea how to solve this?
You can fire selection event in chart load event and set correct extremes:
chart: {
...
events: {
load: function() {
var points = this.series[0].points,
xAxis = this.xAxis[0];
Highcharts.fireEvent(this, 'selection', {
xAxis: [{
min: points[points.length - 51].x,
max: points[points.length - 1].x
}],
});
},
selection: function(event) {
...
}
}
}

is it possible to link/sync 2 chart data in 2 different type of charts to show tooltips at once?
for an example, i have a pie chart and a area chart.
The pie chart represents the percentage of a particular browser and the area chart shows the downloads per year for each browser.
What i need to do is if someone clicks or hovers on section of the pie the relevant line and the tooltip of the area chart should be highlighted...
so when someone clicks/hovers on firefox on the pie, the line relevant to the area should show and vice versa...
is this something possible with highcharts?
So far the work i have done is https://jsfiddle.net/livewirerules/a9tntdam/1/
One thing that i noticed is i have added the event in my area chart to show the color when the tooltip is hovered.
events: {
tooltipRefresh: function(e) {
if (!e.target.hoverSeries) return;
$('.highcharts-tooltip>path:last-of-type')
.css('fill', e.target.hoverSeries.color);
}
}
when i hover a line on the area chart and move to the pie chart, the background color of the tooltips are changed.
I am not sure what would you like to show in a tooltip when you hover on your pie. You have one point so its hard to show tooltip for whole series on another chart.
You can use mouseOver and mouseOut events callback functions for highlighting series (so they will look like on hover):
point: {
events: {
mouseOver: function() {
var name = this.name;
Highcharts.each(chart2.series, function(s) {
if (name === s.name) {
s.setState('hover');
}
});
},
mouseOut: function() {
var name = this.name;
Highcharts.each(chart2.series, function(s) {
if (name === s.name) {
s.setState('');
}
});
}
}
},
You can use tooltip.refresh(point) for refreshing tooltip on specific point:
mouseOver: function(e) {
this.group.toFront();
this.markerGroup.toFront();
var name = this.name;
Highcharts.each(chart.series[0].data, function(p) {
if (name === p.name) {
p.setState('hover');
chart.tooltip.refresh(p)
}
});
},
Here you can see an example how it can work:

I have implemented a wicked-chart which shows 4 series in the legend. Now I want to handle the series click event in legend and update some values outside the wicked highchart.
To be specific, I want to implement exactly like this jsfiddle but in java wicked-chart.
plotOptions:
{
series: {
events: {
legendItemClick: function(event) {
//Do something here
return false;
}
}
I did search all the methods of PlotOptions class but could get something similar to highcharts legendItemClick event.
My solution was not to find alternative for legendItemClick in wicket-charts as they do not have one. Instead I did this:
In your page html, give id="chart". Doing this highcharts shall fix your id to "chartVar" instead of changing it at each run.
<div wicket:id="chart" id="chart"></div>
In your javascript, define your series click using .highcharts-legend-item as below.
var onSeriesClick = function() {
var that = this;
for (var i=0;i<chartVar.series.length;i++)
{
$(".highcharts-legend-item:contains(" + chartVar.series[i].name + ")").click(function(){
// your legend click logic goes here
});
}
}
