Anyone know how to add treemap upon click event on line chart point? Here's my JSFiddle link:
https://jsfiddle.net/ssoj_tellig/d6pfv1bg/19/
When I click on the line chart on the point 0.63 at the third week of sample5, I'd like a treemap to appear at the bottom with the values loaded in var mytreemap_data (or any other values for the demo, doesn't matter). I'd like to understand how it'd work.
Many thanks for your help!
var mytreemap_data = [1528675200000,0.1,0.2,0.3,0.15,0.25]
// How can we show a tree map at the bottom with the values above
// upon clicking on the point 0.63 for the third week of sample 5 ??

Use click event callback function for a point and create another chart with treemap series, for example:
plotOptions: {
series: {
point: {
events: {
click: function() {
Highcharts.chart('treemapContainer', {
series: [{
type: 'treemap',
data: mytreemap_data
}]
})
}
}
},
...
}
}

Below is the chart code, my problem is JSON needs to be used to grab updated data.
I dont want the whole chart to be re-render, but instead only the candles (add the new ones).
I guess there has to be a loop looking every sec in the new data by looping the JSON and create a chart.update?
Would love a answer from anyone with how i should solve this with code!

Looking at the highcharts api quickly on google, you may need an event property followed by load property, and your logic, which would probably include something like
chart: {
events: {
load: function () {
// here's how you would access your series
var series = this.series[0];
setInterval(function () {
//modify your series here.
}, 1000);
}
}
}

I now want to get both of the graphs into one Chart, and it should Update every Minute.
At the Moment I have two php scripts. One for [Timestamp, Temperature] and ohne for [Timestamp, Humidity].
I tried several Code snippets I found here, but i couldn't change it to my needs, because of my not present Javascript knowledge.
Could someone please give me a hint what I should try, or where I could find something that explains what I have to do?
Thank you in advance.
Use setInterval() to run your javascript every time interval as you choose.
http://www.w3schools.com/jsref/met_win_setinterval.asp
is a good tutorial to get to know how it's done.
I hope rest you can do from your current javascript knowledge. Name current two functions, run it inside another function defined inside setInterval function.
If you want to draw two charts on top of each other, pass it as a two-D array to HighChart.
http://www.highcharts.com/demo
contains lot of examples, and you can follow that.
For example,pass an array to a function which contains your code to draw the graph, then use that variable to give value to series.
function draw_first_chart(div_id,x_axis,data_input)
{
$(div_id).highcharts({
chart: {
// ..//
},
title: {
// ..//
},
xAxis: {
// ..//
},
categories: x_axis
},
yAxis: {
// ..//
},
tooltip: {
// ..//
},
legend: {
// ..//
},
series: data_input
});
Here, if you want to display finite values in x axis, send an array to variable x_axis and other data to data_input as an array. If not just ignore variable x_axis and pass an array to data_input. Make sure in the
data_input[i]['name']
should contain all graph titles (Humidity, Tempreture) and
data_input[i]['data']
contains data. i is the number for each graph.
Hope this helps.
After resizing the graph area or browser window, the tool tip popup wont show on mouse-over in highcharts.

This is bug already reported on our bug tracker here. It should be fixed in 4.1.4/2.1.4 versions.
just give chart container width in percentage like below or use redraw() function upon resizing browser window or graph area.
<div id="chartcontainer" width='100%'></div>

I cannot get highcharts to recognize my timestamps, they are in javascript date format.
Tried many different approaches, but cannot get it to work when both the data and time array's are seperate.
Fiddle: http://jsfiddle.net/SjL6F/
$(function () {
Highcharts.setOptions({
lang: {
thousandsSep: ''
}
});
$('#container').highcharts({
title: {
text: 'Temperature - Last 24 hours',
},
credits: {
enabled: false
},
subtitle: {
text: "Test Site",
x: -20
},
xAxis: {
type: 'datetime',
labels: {
enabled: true
},
categories: time,
tickInterval: 3600 * 1000,
dateTimeLabelFormats: {
day: '%e of %b'
}
},
yAxis: [{
title: {
text: 'Temperature (\u00b0C)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
}],
tooltip: {
shared: true
},
series: [{
name: 'Temperature',
data: temp,
type: 'line',
tooltip: {
valueSuffix: ' C'
},
marker: {
enabled: false
}
}]
});
});
Highcharts just shows the raw javascript date value.
You are setting categories, which isn't datetime type for xAxis. Remove them, then concat time and temp arrays.
For example:
var concatenatedData = [];
$.each(time, function(i, e){
concatenatedData.push([parseInt(e), temp[i]]);
});
Demo:
http://jsfiddle.net/SjL6F/1/
Note: I have added parseInt, because Highcharts requires timestamps to be numbers, not strings.
