Highcharts polar wind rose chart with segments in trapezoid form - javascript

I am using extjs and highcharts to develop a wind rose chart. I need to display the data as trapezoids with straight edges, rather than the default display of the segments with arcs as delimiters. Here is an image of what I am trying to do
I have been able to integrate the highcharts object into my application using the wrapper provided by JoeKuan
However I am not seeing in the highcharts documentation how I can configure the polar chart columns into straight edged segments as seen in the image..
Here is a fiddle of the polar chart as it works currently.. Fiddle
Highcharts.chart('container', {
data: {
table: 'freq',
startRow: 1,
endRow: 17,
endColumn: 7
},
chart: {
polar: true,
type: 'column'
},
title: {
text: 'Wind rose for South Shore Met Station, Oregon'

plotOptions: {
series: {

});
All help greatly appreciated

You want type: 'area' to achieve that visualization.
Highcharts.chart('container', {
data: {
table: 'freq',
startRow: 1,
endRow: 17,
endColumn: 7
},
chart: {
polar: true,
type: 'area'
},

on highchart 8.0.0 is possible zoom using the wheel
the problem is highcharts do an animation on scroll
I red the documentation but I only found disable all animations
is it posible do that?
$('#container').highcharts({
chart: {
panning: true
},
mapNavigation: {
enabled: true,
enableButtons: true
},
title: {

});
here is in jsfiddle

thanks in advance

I think that set chart.animation to false is a solution which you are looking for. It will disable animation for all chart updating, but the initial one will stay unchanged.
Demo: https://jsfiddle.net/BlackLabel/jLm8yrt6/
chart: {
panning: true,
animation: false
},
API: https://api.highcharts.com/highcharts/chart.animation
Is that what you had in mind?

I am trying to create a chart like this one:
:
I have already achieved all of the features except the multi colored line of the area chart. I want to show the different gradients of the chart in different colors, thus I need multiple colors on the line.
I have already tested zones like shown here and also common plugins like this. Both do not work. The zones are applied to the area which I do not want and the plugin can only color lines OR areas but not only lines in area charts.
My current Highcharts settings look like this:
{
title: {
text: null
},
xAxis: {
crosshair: true,
labels: {
format: '{value} km'
},
title: {
text: null
},
opposite: true,
startOnTick: true,
endOnTick: false,
min: 0
},
yAxis: {
startOnTick: true,
showFirstLabel: false,
endOnTick: false,
maxPadding: 0.35,
title: {
text: null
},
min: 100,
labels: {
format: '{value} m'
}
},
plotOptions: {
dataGrouping: {
enabled: false
},
showInNavigator: true,
stacking: 'normal',
series: {
dragDrop: {
draggableY: true
},
point: {
events: {
mouseOver: (e) => {
this.chartHover.emit({
distance: e.target.x * 1000
});
},
}
},
},
area: {
dragDrop: {
draggableY: true,
dragPrecisionY: 1
}
}
},
credits: {
enabled: false
},
legend: {
enabled: false
},
chart: {
update: true,
styledMode: true,
marginBottom: 0,
marginRight: 0
},
tooltip: {
headerFormat: '',
pointFormatter: function () {
let point = this;
if (!this.series) {
return;
}
return '<span class="tooltip-area-series-' + this.series.index + '">\u25CF</span> ' + point.series.name + ': <b>' + point.y + 'm</b><br/>';
},
shared: true
},
series: [],
};
Is there an built-in solution for this?
EDIT:
I used the proposed solution by ppotaczek:
series: [{
type: 'areaspline',
id: 'areaSeries',
data: data
}, {
type: 'spline',
linkedTo: 'areaSeries',
data: data,
zoneAxis: 'x',
zones: [{
color: 'red',
value: 2
}, {
color: 'green',
value: 4
}]
}]
This works pretty good, but has some performance pitfalls when you try to add approx. more than 150 zones on desktop browsers.
There is also a small rendering issue - small gaps between the zones.
Best,
Philipp

You can add an extra spline series with zones:
series: [{
type: 'areaspline',
id: 'areaSeries',
data: data
}, {
type: 'spline',
linkedTo: 'areaSeries',
data: data,
zoneAxis: 'x',
zones: [{
color: 'red',
value: 2
}, {
color: 'green',
value: 4
}]
}]

I created document with highcharts scatter graph
Highcharts.chart('container', {
chart: {
type: 'scatter',
zoomType: 'xy'
},
title: {
text: ''
},
subtitle: {
text: ''
},
xAxis: {
title: {
enabled: true,
text: 'Date of entry'
},
startOnTick: true,
endOnTick: true,
showLastLabel: true
},
yAxis: {
title: {
text: 'Values'
}
},
legend: {
layout: 'vertical',
align: 'left',
verticalAlign: 'top',
x: 100,
y: 70,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF',
borderWidth: 1
},
plotOptions: {
scatter: {
marker: {
radius: 5,
states: {
hover: {
enabled: true,
lineColor: 'rgb(100,100,100)'
}
}
},
states: {
hover: {
marker: {
enabled: false
}
}
},
tooltip: {
headerFormat: '<b>{series.name}</b><br>',
pointFormat: 'Dana {point.x} = {point.y}'
}
}
},
series: [{
name: 'Values',
color: 'rgba(223, 83, 83, .5)',
data: [[167.6, 64.5], [167.6, 72.3], [167.6, 61.4]]
}]
});
and this works. This code is from documentation page. I get normal scatter data like on this page Highcharts scatter jsfiddle
Now, I created another PHP file that produces me with data I actually need. it is in document highcharts.php and result is this
[07.03.2017,21000],[07.03.2017,25000],[07.03.2017,33000],[07.03.2017,27000],[07.03.2017,30000],[01.01.2017,700],[11.05.2017,0],[11.05.2017,0],[11.05.2017,0],[11.05.2017,0],
how to connect data to this highcharts.php file? I found some examples but I cannot get it to work. So for start I need this, ONE line of data to show on scatter diagram. I lost few days and just do not get it what I am doing wrong.

If your PHP file returns the array presented above, you need to parse it a little bit in order to use it as data array in a scatter series. First of all, dates should be strings. Secondly, you need to use new Date() to create Date instance and use getTime() to return timestamps. Also, change xAxis type to datetime.

I am new to highChart and even after following the documentation I am not able to correctly plot the x-axis. It only labels the the first element of the dateAndTimeArray array.Can you please tell me where I am making mistake. Here is my code.

DEMO

The chart is plotting what you asked it to. You have 4 series of data. Each series has one data point. I think you confusing the series.name and xAxis point. Since each of your series has just one point it is assigned to the first category in your xAxis.categories.
The question then becomes:
Do you want to have a categorical xAxis or a datetime xAxis?
Your data leads itself to categorical but your xAxis.categories don't line up with your series.name entries and your xAxis.categories are not in ascending time order. You also are setting a categorical list of items but telling highcharts that your chart is type: 'datetime'. You need to pick one.
Here is an example using categorical type.
Here is an example using datetime type.

I am trying to use this Javascript to create a scatter plot: http://www.highcharts.com/demo/scatter/gray
Im using it just like it shows there and when i copy the graph with the info from the example it works fine.
I created a function to populate the table to how I want...this is how my code looks
<div id="container" style="min-width: 400px; height: 400px; margin: 0 auto">
<script>
var rateValueData = <?php echo json_encode($data);?>;
$(function (scatter) {
$('#container').highcharts({
chart: {
type: 'scatter',
zoomType: 'xy'
},
title: {
text: 'Height Versus Weight of 507 Individuals by Gender'
},
subtitle: {
text: 'Source: Heinz 2003'
},
xAxis: {
title: {
enabled: true,
text: 'Height (cm)'
},
startOnTick: true,
endOnTick: true,
showLastLabel: true
},
yAxis: {
title: {
text: 'Weight (kg)'
}
},
legend: {
layout: 'vertical',
align: 'left',
verticalAlign: 'top',
x: 100,
y: 70,
floating: true,
backgroundColor: '#FFFFFF',
borderWidth: 1
},
plotOptions: {
scatter: {
marker: {
radius: 5,
states: {
hover: {
enabled: true,
lineColor: 'rgb(100,100,100)'
}
}
},
states: {
hover: {
marker: {
enabled: false
}
}
},
tooltip: {
headerFormat: '<b>{series.name}</b><br>',
pointFormat: '{point.x} cm, {point.y} kg'
}
}
},
series: [{
name: 'Female',
color: 'rgba(223, 83, 83, .5)',
data: THIS IS WHERE I NEED TO USE THE VARIABLE!!!!
}, ]
});
});
</script>
so the function to create the Variable works but then how can i use that variable to populate the data for the graph
This is what the variable displays at when I echo it out:
var rateValueData = [["7.59090","104.2"],["1.58181","101.3636364"],["0.86363","106.5090909"],["0.7","73.86363636"],["2.7","94.38571429"],["2.48333","104.4727273"],["22.45","103"],["4.09090","105.3888889"],["1.91818","102.2909091"],["1.85","94.82727273"],["62.1","102.7666667"],["6.31818","100.7454545"],["2.31818","107.9545455"],["5.8","99.9625"],["1.92727","105.4727273"],["1.1","102.3"],["16.95","99.40909091"],["0.6","96.35"],["81.68","103.7909091"],["11.5818","116.7363636"],["2.64545","104.8111111"],["1.72","105.73"],["1.24545","104.9272727"],["1.35454","101.9363636"],["32.6363","99.05"],["15.5727","102.05"],["0.8","103.6"],["2.37272","109.7818182"],["0.9","99.62727273"],["4.05454","93.06363636"],["1.1","101.2272727"],["2.70909","102.5888889"],["1.35454","106.3363636"],["41.2181","101.3375"],["0.52727","104.4363636"],["14.8818","107.3909091"],["2.18333","98.82727273"],["3.7","66.70909091"],["10.3272","113.5545455"],["2.31428","96.51818182"],["1.14","101.7727273"],["11.9727","102.4272727"],["1.68571","101.3727273"],["1.48181","102.1454545"],["1.3","103.5181818"],["12.3090","100.8545455"],["0.91818","101.9272727"],["6.51","92.75"],["10.7818","98.05"],["21.46","97.95"],["8.35","98.85"],["7.6625","98.53"],["2.79090","106.1909091"],["1.17","107.3090909"],["19.9181","107.6909091"],["0.61666","50.03636364"],["2.68181","104.5818182"],["1.11428","80"],["1.93333","105.0454545"],["0.84545","99.36"],["2.46363","105.8714286"],["1.49090","104.9272727"],["50.4545","106.6636364"],["1.24545","103.9363636"],["1.01818","102.1636364"],["1.12727","104.7090909"],["2.22222","96.01818182"],["7.83636","101.4090909"],["4.5","98.98181818"],["8.99090","116.1571429"],["1.67272","105.1545455"],["6.25","106.5727273"]];
That is the data that I need to plot in the scatter chart.
Can anybody help me out?
Let me know if you need more info

The problem is your array contains string instead of numeric value.
Try with
var rateValueData = [[7.59090,104.2],[1.58181,101.3636364],[0.86363,106.5090909],[0.7,73.86363636],[2.7,94.38571429],[2.48333,104.4727273],[22.45,103],[4.09090,105.3888889],[1.91818,102.2909091],[1.85,94.82727273],[62.1,102.7666667],[6.31818,100.7454545],[2.31818,107.9545455],[5.8,99.9625],[1.92727,105.4727273],[1.1,102.3],[16.95,99.40909091],[0.6,96.35],[81.68,103.7909091],[11.5818,116.7363636],[2.64545,104.8111111],[1.72,105.73],[1.24545,104.9272727],[1.35454,101.9363636],[32.6363,99.05],[15.5727,102.05],[0.8,103.6],[2.37272,109.7818182],[0.9,99.62727273],[4.05454,93.06363636],[1.1,101.2272727],[2.70909,102.5888889],[1.35454,106.3363636],[41.2181,101.3375],[0.52727,104.4363636],[14.8818,107.3909091],[2.18333,98.82727273],[3.7,66.70909091],[10.3272,113.5545455],[2.31428,96.51818182],[1.14,101.7727273],[11.9727,102.4272727],[1.68571,101.3727273],[1.48181,102.1454545],[1.3,103.5181818],[12.3090,100.8545455],[0.91818,101.9272727],[6.51,92.75],[10.7818,98.05],[21.46,97.95],[8.35,98.85],[7.6625,98.53],[2.79090,106.1909091],[1.17,107.3090909],[19.9181,107.6909091],[0.61666,50.03636364],[2.68181,104.5818182],[1.11428,80],[1.93333,105.0454545],[0.84545,99.36],[2.46363,105.8714286],[1.49090,104.9272727],[50.4545,106.6636364],[1.24545,103.9363636],[1.01818,102.1636364],[1.12727,104.7090909],[2.22222,96.01818182],[7.83636,101.4090909],[4.5,98.98181818],[8.99090,116.1571429],[1.67272,105.1545455],[6.25,106.5727273]];
