Receiving NaN error when running javascript function

Receiving NaN error when running javascript function - javascript

I have a page that uses send data (in the example below the number 2) from a div to a javascript function but it does not seem to be working correctly. The alert comes up as shown. Any ideas?
THE DIV LINE
<div id="containerbar" data-F1="2" style="min-width: 200; height: 400px; margin: 0 auto"></div>
THE JAVASCRIPT
<script>
$(function () {
var $bardata = $("#containerbar");
var valueF1 = parseInt($bardata.data('F1'));
alert("Val1: " + valueF1);
$bardata.highcharts({
chart: {
type: 'bar'
},
title: {
text: 'Teacher count per slider'
},
xAxis: {
categories: ['Feedback', 'Challenge & differentiation', 'Classroom talk', 'Skills development', 'Expectations & relationships'],
title: {
text: null
}
},
yAxis: {
min: 0,
title: {
text: 'Count',
align: 'high'
},
labels: {

}
},

},

x: -40,
y: 100,
floating: true,
borderWidth: 1,
backgroundColor: '#FFFFFF',
shadow: true
},
credits: {

},
series: [{
name: '1st quartile',
data: [valueF1 , 4, 1, 0, 0]
}, {

Highcharts plotbands different per category

I am attempting to create the following chart:
However I can't seem to get the plotbands to work in this way; right now, they fill the entire axis:
I am not sure if I should use annotations instead, but so far I haven't gotten it to work. What can I try next?

This kind of plotBand shape is not possible from the API level, but you can simulate it in several ways. Example configurations:
SVG Renderer:
chart: {
events: {
render() {
const chart = this;
if (chart.rects) {
chart.rects = chart.rects.destroy();
}
chart.rects = chart.renderer.g('rects').attr({
zIndex: 1
}).add();
let x = chart.xAxis[0].toPixels(1),
y = chart.yAxis[0].toPixels(4),
width = chart.xAxis[0].toPixels(2) - chart.xAxis[0].toPixels(1),
height = chart.yAxis[0].toPixels(2) - chart.yAxis[0].toPixels(4);
chart.rect = chart.renderer.rect(x, y, width, height)
.attr({
fill: 'grey'
}).add(chart.rects)
chart.rect = chart.renderer.rect(chart.xAxis[0].toPixels(3), y, width, height)
.attr({
fill: 'grey'
}).add(chart.rects)
}
}
},

How to show an empty chart in beginning and populate values on button click

I have code from this post. I want to populate the chart on click of a button instead of initializing it and provide only 3 values e.g.22286,12286,9286 ( these values would be dynamic) and plot the chart with the same appearance (i.e. 3 colors chart) as of the snippet
Highcharts.chart('container', {
colors: ['#762232', '#EFCA32', '#007788'],
title: {

series = this.chart.series;
series.forEach(function(s) {
tickPositions.push(s.processedYData[s.processedYData.length - 1]);
});
tickPositions.sort(function(a, b) {
return a - b;
});
return tickPositions;

<button>Populate Chart</button>

All you need to do is to create series with empty data array and use chart.update method to add data. Example:
var chart = Highcharts.chart('container', {
...,
series: [{
data: []
}, {
data: []
}, {
data: []
}]
});
document.getElementById('chartInit').addEventListener('click', function(){
chart.update({
series: [{
data: [4457, 13371, 22286]
}, {
data: [2457, 9371, 12286]
}, {
data: [1457, 5371, 9286]
}]
});
});

Align Highcharts bars right

I used the opposite attribute to move the xAxis to the right. How is it possible that the bars will also start on the right side?
Thanks!
Highcharts.chart('absoluteInterruptions', {

<div id='absoluteInterruptions'></div>

Found this from the documentation and managed to get it to work by setting
yAxis:{reversed:true}
By reversing the y-axis the bars go from right to left.
Highcharts.chart('absoluteInterruptions', {
chart: {
type: 'bar',
rotate: -90
},
title: {

},

how to show Y axis (not it label) in jquery?

I am using highchart with jquery .I am able to show X-axis with label (Apple,pears)..But I want to show Y-axis without lable .In other words I want to show a straight line on Y-axis.
here is my code
http://jsfiddle.net/3sembmfo/118/
$(function () {
// Configure the chart
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Highcharts axis visibility'
},
xAxis: {
categories: ['Apples', 'Pears', 'Oranges', 'Peaches']
},
yAxis: {
allowDecimals: false,
title: {
text: 'Fruit'
},
visible: false
},
plotOptions: {
series: {
stacking: 'normal',
dataLabels: {
enabled: true
}
}
},
series: [{
data: [1, 3, 2, 4],
name: 'Ola'
}, {
data: [5, 4, 5, 2],
name: 'Kari'
}]
});
var yVis = false,
xVis = true;
});

This can, and should, be resolved by options:
yAxis.lineWidth - to enable the line
yAxis.title.text - to hide the title
yAxis.gridLineWidth - to disable horizontal lines,
yAxis.labels.enabled - to disable labels
Working demo: http://jsfiddle.net/BlackLabel/3sembmfo/122/
Snippet:
yAxis: {
allowDecimals: false,
title: {
text: null
},
labels: {
enabled: false
},
gridLineWidth: 0,
lineWidth: 1,
visible: true
},

Replace your y Axis code with this. http://jsfiddle.net/3sembmfo/119/. If you have any query let me know.
yAxis: {
allowDecimals: false,
labels:{
style: {
fontSize:'0px'
}
},
title: {
text: 'Fruit',
style: {
fontSize:'0px'
}
},
visible: true
},

You have to use Highcharts.SVGRenderer and add line using load event.
chart: {
type: 'column',
events: {
load: function() {
var ren = this.renderer;
ren.path(['M', 10, 10, 'L', 10, this.chartHeight * .8])
.attr({
'stroke-width': 1,
stroke: '#000'
})
.add();
}
}
},
Fiddle demo
$(function() {
// Configure the chart
$('#container').highcharts({
chart: {
type: 'column',
events: {
load: function() {
var ren = this.renderer;
ren.path(['M', 10, 10, 'L', 10, this.chartHeight * .8])
.attr({
'stroke-width': 1,
stroke: '#000'
})
.add();
}
}
},
title: {
text: 'Highcharts axis visibility'
},
xAxis: {
categories: ['Apples', 'Pears', 'Oranges', 'Peaches'],
},
yAxis: {
allowDecimals: false,
title: {
text: ''
},
labels: {
enabled: false
},
gridLineWidth: 0,
},
plotOptions: {
series: {
stacking: 'normal',
dataLabels: {
enabled: true
}
}
},
series: [{
data: [1, 3, 2, 4],
name: 'Ola'
}, {
data: [5, 4, 5, 2],
name: 'Kari'
}]
});
var yVis = false,
xVis = true;
});
#container {
min-width: 300px;
max-width: 800px;

How to do a data overlap independently column in Highcharts

I would like to have something similar to the image below, but the columns representing the classes all stack together now. How do I separate them and allow them to load dynamically as well?
Also I need a legend that says green is band 1, yellow is band 2, orange is band 3 and red is band 4, how do i do that as well? My code is in the JS Fiddle page. I am not allowed to use jQuery, need to use pure JavaScript.
var options = {
chart: {
renderTo : 'container',
type: 'column'
},
title: {
text: 'Topic & Subtopic Mastery'
},
subtitle: {
text: 'Average Level-Stream Mastery vs Average Class Mastery'
},
xAxis: {
categories: topics
},
yAxis: {
min: 0,
max: 100,
title: {
text: 'Mastery'
}
},
legend: {
layout: 'vertical',
backgroundColor: '#FFFFFF',
align: 'left',
verticalAlign: 'top',
x: 100,
y: 70,
floating: true,
shadow: true
},
tooltip: {
shared: true,
valueSuffix: ' %'
},
plotOptions: {
column: {
grouping: false,
shadow: false
}
},
series: resultsData
};
http://jsfiddle.net/kscwx139/2/

I came up with a solution you are looking for with specifying x and y axis data for level and giving appropriate width to the point.
$(function() {
var chart;
$(document).ready(function() {
var i = 0;
Highcharts.getOptions().colors = Highcharts.map(Highcharts.getOptions().colors, function(color) {
if (i == 0) {
i++;
return Highcharts.Color(color)
.setOpacity(1)
.get('rgba');
} else {
i++;
return Highcharts.Color(color)
.setOpacity(0.5)
.get('rgba');
}
});
var colors = Highcharts.getOptions().colors;
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'column',
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
borderColor: null
},
title: {
text: 'Mailboxes over Quota'
},
subtitle: {
text: 'Mailbox Size in MB'
},
exporting: {
enabled: false
},
credits: {
enabled: false
},
xAxis: {
categories: ["Overall Topic", "Topic 1", "Topic 2"],
title: {
text: null
}
},
yAxis: {
min: 0,
title: {
text: 'Total',
align: 'high'
},
allowDecimals: false,
},
tooltip: {
formatter: function() {
return '' +
this.series.name + ': ' + Highcharts.numberFormat(this.y, 0, '.', ',');
}
},
legend: {
enabled: true
},
credits: {
enabled: false
},
series: [{
name: 'Level',
color: colors[0],
data: [{
y: 86,
x: 0.25
}, {
y: 80,
x: 1.25
}, {
y: 95,
x: 2.25
}],
pointWidth: 80
}, {
name: '4A',
data: [90, 88, 97]
}, {
name: '4B',
data: [95, 78, 92]
}, {
name: '4C',
data: [80, 69, 84]
}]
});
});
});
To show in label inside your column you can use below code.
plotOptions: {
column: {
dataLabels: {
enabled: true,
formatter: function() {
return this.series.name;
},
y: 25,
}
}
}
You can see it in action at this JSFIddle
