Remove Zero From the HIGHCHART - javascript

I have been working on Highcharts just got into one trouble the problem is when there is not any value exist for some data on the chart then it displays 0 on it which looks bad kindly checkout the following jsfiddle the labels on the chart gets populated by the following function but i am not able to put check on it that it should display only those bars whose values are above zero on the chart
http://jsfiddle.net/CzHyC/3/ [KINDLY CHECK THE APPLE section on the chart]
$(function () {
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'column'
},
title: {
text: 'Stacked column chart'
},
xAxis: {
categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas']
},
yAxis: {
min: 0,
title: {
text: 'Total fruit consumption'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: (Highcharts.theme && Highcharts.theme.textColor) || 'blue'
}
}
},
legend: {
align: 'right',
x: -100,
verticalAlign: 'top',
y: 20,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColorSolid) || 'gray',
borderColor: '#CCC',
borderWidth: 1,
shadow: false
},
tooltip: {
formatter: function() {
return '<b>'+ this.x +'</b><br/>'+
this.series.name +': '+ this.y +'<br/>'+
'Total: '+ this.point.stackTotal;
}
},
plotOptions: {
column: {
stacking: 'normal',
dataLabels: {
enabled: true,
color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white'
}
}
},
series: [{
name: 'John',
data: [0, 3, 4, 7, 2]
}, {
name: 'Jane',
data: [2, 2, 3, 2, 1]
}, {
name: 'Joe',
data: [3, 4, 4, 2, 5]
}]
});
});
});

This is the way I have dealt with this situation.
When you are creating your data points, instead of putting a 0, put a null.
So for example your data array will look like:
[null,3,4,7,2] instead of [0,3,4,7,2]

Sort stackbar chart in highchart based on size of each stackbar

https://jsfiddle.net/vasjav1/ywspnocd
I wants to sort the stackbar chart from min to max, i.e. smallest bar should occurs first, and largest should occur at the end. I didn't find any solution being present anywhere else related to stackbar chart. there is solution present here https://www.highcharts.com/docs/advanced-chart-features/data-sorting, but it's mostly fitting for the barchart, but I couldn't fit it with the stack bar. Can someone please help me to sort stackbarchart?
Highcharts.chart('container', {
chart: {
type: 'column'
},
title: {
text: 'Stacked column chart'
},
xAxis: {
categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas']
},
yAxis: {
min: 0,
title: {
text: 'Total fruit consumption'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
}
}
},

align: 'right',
x: -30,
verticalAlign: 'top',
y: 25,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.background2) || 'white',
borderColor: '#CCC',
borderWidth: 1,
shadow: false
},
tooltip: {
headerFormat: '<b>{point.x}</b><br/>',
pointFormat: '{series.name}: {point.y}<br/>Total: {point.stackTotal}'
},
plotOptions: {
column: {
stacking: 'normal',
dataLabels: {
enabled: true,
color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white'
}
}
},
series: [{
name: 'John',
data: [5, 3, 4, 7, 2]
}, {
name: 'Jane',
data: [2, 2, 3, 2, 1]
}, {
name: 'Joe',
data: [3, 4, 4, 2, 5]
}]
});
You would first have to sort the data and then feed it to highcharts. For instance, if your input data can be represented as this:
{
"Apples": { "John": 5, "Jane": 2, "Joe": 3 },
"Oranges": { "John": 3, "Jane": 2, "Joe": 4 },
"Pears": { "John": 4, "Jane": 3, "Joe": 4 },
"Grapes": { "John": 7, "Jane": 2, "Joe": 2 },
"Bananas": { "John": 2, "Jane": 1, "Joe": 5 },
};
...then you could sort that, and then translate it to the argument you want to pass to highcharts:
// The original input data in one object (or array):
let data = {
"Apples": { "John": 5, "Jane": 2, "Joe": 3 },
"Oranges": { "John": 3, "Jane": 2, "Joe": 4 },
"Pears": { "John": 4, "Jane": 3, "Joe": 4 },
"Grapes": { "John": 7, "Jane": 2, "Joe": 2 },
"Bananas": { "John": 2, "Jane": 1, "Joe": 5 },
};
// Sort the data by sum of values:
let sorted = Object.entries(data).map(([cat, obj]) =>
[cat, obj, Object.values(obj).reduce((a, b) => a + b)]
).sort((a, b) => a[2] - b[2]);
// Now generate the argument for the chart:
Highcharts.chart('container', {
chart: {
type: 'column'
},
title: {
text: 'Stacked column chart'
},
xAxis: {
categories: sorted.map(([cat]) => cat)
},
yAxis: {
min: 0,
title: {
text: 'Total fruit consumption'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
}
}
},
legend: {
align: 'right',
x: -30,
verticalAlign: 'top',
y: 25,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.background2) || 'white',
borderColor: '#CCC',
borderWidth: 1,
shadow: false
},
tooltip: {
headerFormat: '<b>{point.x}</b><br/>',
pointFormat: '{series.name}: {point.y}<br/>Total: {point.stackTotal}'
},
plotOptions: {
column: {
stacking: 'normal',
dataLabels: {
enabled: true,
color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white'
}
}
},
series: Object.keys(sorted[0][1]).map(name => ({
name, data: sorted.map(([_, {[name]: val}]) => val)
}))
});
<script src="https://code.highcharts.com/highcharts.js"></script>

Currently, the data-sorting feature works only with individual series.
You can use dependent sorting as described here (example: https://jsfiddle.net/BlackLabel/3f8x7j5w/)
series: [{
id: 'mainSeries',
dataSorting: {
enabled: true
},
data: [...]
}, {
linkedTo: 'mainSeries',
data: [...]
}, {
linkedTo: 'mainSeries',
data: [...]
}, {
linkedTo: 'mainSeries',
data: [...]
}]
or sort each series individually (example: https://jsfiddle.net/BlackLabel/dsm0bz3k/), but the best way will be to use the solution from trincot's answer.

Hide datalabels inside stacked column chart if we have 1 data

I need to hide the inside datalabels if there is only one dataset which is greater than zero. What I mean by dataset is
series: [{
name: 'John',
data: [5, 3, 0, 7, 2]
}, {
name: 'Jane',
data: [2, 2, 0, 2, 0]
}, {
name: 'Joe',
data: [3, 4, 3, 2, 0]
}]
If series.data[i] all are zero except one then hide the inside data labels. In the above case the 3rd and 5th dataset has 0,0,3 and 2,0,0 values only 1 non zero value so hide the inside datalabel.
Highcharts.chart('container', {
chart: {
type: 'column'
},
title: {
text: 'Stacked column chart'
},
xAxis: {
categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas']
},
yAxis: {
min: 0,
title: {
text: 'Total fruit consumption'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: ( // theme
Highcharts.defaultOptions.title.style &&
Highcharts.defaultOptions.title.style.color
) || 'gray'
}
}
},
legend: {
align: 'right',
x: -30,
verticalAlign: 'top',
y: 25,
floating: true,
backgroundColor:
Highcharts.defaultOptions.legend.backgroundColor || 'white',
borderColor: '#CCC',
borderWidth: 1,
shadow: false
},
tooltip: {
headerFormat: '<b>{point.x}</b><br/>',
pointFormat: '{series.name}: {point.y}<br/>Total: {point.stackTotal}'
},
plotOptions: {
column: {
stacking: 'normal',
dataLabels: {
enabled: true,
formatter:function() {
if(this.y != 0) {
return this.y;
}
}
}
}
},
series: [{
name: 'John',
data: [5, 3, 0, 7, 2]
}, {
name: 'Jane',
data: [2, 2, 0, 2, 0]
}, {
name: 'Joe',
data: [3, 4, 3, 2, 0]
}]
});
Here I have highlighted which datalabel should need to be remove from inside..
In the formatter function you can check if at least two of the series have y value greater than 0.
plotOptions: {
column: {
stacking: 'normal',
dataLabels: {
enabled: true,
formatter: function() {
var series = this.series.chart.series,
xPos = this.point.x,
filteredSeries;
if (this.y != 0) {
filteredSeries = series.filter((s) => (s.yData[xPos]));
return filteredSeries.length > 1 ? this.y : '';
}
}
}
}
}

Highcharts dashed line on x axis not going all the way across

I have this highchart's jsfiddle and I want the dashed line to go all the way across the graph from 0-10.I have tried this out on a different graph called scatter and it works I want it to work on the type column graph. How do I do this? Is there something in the highcharts api that I am missing?

To create such type of lines, you should use yAxis.plotLines:
yAxis: {
...,
plotLines: [{
value: 10,
zIndex: 2,
width: 2,
dashStyle: "Dash",
color: 'black',
}]
}

Passing list of dictionary to a .js file to create highcharts using python flask [duplicate]

This question already has answers here:
JavaScript raises SyntaxError with data rendered in Jinja template
(3 answers)
Closed 4 years ago.
I'm trying to pass a list of dictionary to a .js file to create highcharts using python flask. Can someone help me figure out how can I call pass the key value pairs to x and y axis in a stacked bar chart?
app.py
typeuser_dict=[{u'dave': [163, 330, 17, datetime.datetime(2018, 7, 20, 0, 0)]}]
return render_template('profile.html', typeuser_dict=typeuser_dict)
barchart.js
Highcharts.chart('container', {
chart: {
type: 'column'
},
title: {
text: 'Stacked column chart'
},
xAxis: {
categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas']
},
yAxis: {
min: 0,
title: {
text: 'Total fruit consumption'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
}
}
},
legend: {
align: 'right',
x: -30,
verticalAlign: 'top',
y: 25,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.background2) || 'white',
borderColor: '#CCC',
borderWidth: 1,
shadow: false
},
tooltip: {
headerFormat: '<b>{point.x}</b><br/>',
pointFormat: '{series.name}: {point.y}<br/>Total: {point.stackTotal}'
},
plotOptions: {
column: {
stacking: 'normal',
dataLabels: {
enabled: true,
color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white'
}
}
},
series: [{
name: 'A',
data: [5, 3, 4, 7, 2]
}, {
name: 'J',
data: [2, 2, 3, 2, 1]
}, {
name: 'Z',
data: [3, 4, 4, 2, 5]
}]});
Basically series in barchart.js should get my list value from typeuser_dict.
You can emit raw strings to your HTML template using
var x ={{my_x_from_flask|safe}}
and use var x however you like.
And from python side you have to extract value of x and pass it
You can directly pass the JSON string and use that thing as proper JSON in JS side.
