Column width in Highcharts when combined with spline - javascript

I have this annoying thing in Highcharts that I cannot figure out. I have graphs that are dynamically generated and can contain multiple columns and splines. In the example the spline is a temperature measurement and contains lots of data points. The two columns are grouped by day and therefore contain only one value per day.
When I use this combination the column width becomes almost invisible:

$(function () {
$('#container').highcharts({
chart: {
zoomType: 'xy'
},

text: 'Test'

I have been searching for ways to dynamically control the width of columns by using pointWidth but this gets me into a hole new area of issues, as I am not always sure if there is a combination of columns and splines and what the date range is.
Is there a trick to solve this? I hope I have missed something simple.


I was reading through the API description of Highcharts when I noticed an option to have multiple x axis. Since my problem seemed to be related to scaling on the x axis I decided to give it a go...
I created a new x axis for the line data and it works like a charm. Of course we do not want to see multiple x axis, so a little fiddling with the settings hides it again.
My x axis definition now looks like this:
xAxis: [{
type: 'datetime',
},{
type: 'datetime',
lineWidth: 0,
minorGridLineWidth: 0,
lineColor: 'transparent',
opposite: true,
labels: {
enabled: false
},
minorTickLength: 0,
tickLength: 0
}],
On the data series that has 'too many' points I simply added 'xAxis: 1'.

Section wise labeling in highchart

I'm making a graph with multiple y-axis using this Highchart but i'm stuck while making multiple labels for x-axis.
currently i reached on this
Highcharts.chart('container', {
chart: {
zoomType: 'xy'
},
title: {
text: 'Average Week Comparison'
},
subtitle: {
text: 'Values: Wastage and OEE'
},

yAxis: 1,
data: oee.reverse(),

}
}, {

type: 'spline',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5],
tooltip: {
valueSuffix: ' %'
}
}]
});
current output is this where i manipulated x and y axis dynamically.
Now i want to add sections on x-axis values in 3 value chunks
below is the relevant graph(not actual)
I'm not good at JS can anyone help me to figure out whether it is possible to print x-axis in sections like above image.
Your help will be highly push me to solve this problem.
Also if any other library can do it? you can mention its link.

You can use 'grouped-categories.js' plugin.
xAxis: {
categories: [{
name: "Fruit",
categories: ["Apple", "Banana", "Orange"]
}, {
name: "Vegetable",
categories: ["Carrot", "Potato", "Tomato"]
}, {
name: "Fish",
categories: ["Cod", "Salmon", "Tuna"]
}]
}

Highcharts bar format datalabels to percent and add text

I have highcharts bar.
How I can format my datalabel to percent and add text datalabels (how i can reposition this text? It's need me for create vertical version of this bar) ?
In the end, it should turn out like this in a horizontal or vertical solution.
Highcharts.chart('container', {
chart: {
type: 'bar'
},
title: {
text: 'Activity'
},
xAxis: {
categories: ['Activity']
},
yAxis: {
min: 0,
title: {
text: ''
}
},
legend: {
reversed: true
},
plotOptions: {
series: {
borderWidth: 0,
stacking: 'normal',
pointWidth: 3,
dataLabels: {
enabled: true,
y: 2,
verticalAlign: 'top',
align: 'left',
color: '#000000',
style: {
textOutline: false
}
}
}
},
series: [{
name: 'One',
data: [10],
color: '#f45b69'
}, {
name: 'Two',
data: [20],
color: '#44bba4'
}, {
name: 'Three',
data: [30],
color: '#ff9f1c'
}]
});
<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/modules/exporting.js"></script>
<div id="container" style="min-width: 310px; max-width: 800px; height: 400px; margin: 0 auto"></div>

To just show the number with a percentage sign behind as well as the series name you can set the dataLabels format like this:
plotOptions: {
series: {
format: '{y} % <br/> {series.name}',
...
}
}
If you want to change how it looks or have more customize-ability you can use formatter instead of format.
Working example: https://jsfiddle.net/ewolden/y5ygdx2a/1/

Highcharts is rounding off the decimal values to 0. How to avoid it?

I am passing the ecpm as you can see below as ["0.4", "0.2", "0.6", "0.3"] to be the data for y axis to draw a spline on a multi axis graph, using highcharts. But it is drawing the spline as a straight horizontal line considering the values as 0. Values on tooltip for every point is also coming as 0.
Following is the script used:
$('#dual-axes-line-and-column4').highcharts({
chart: {
zoomType: 'xy'
},
title: {
text: 'Some Matrix'
},
subtitle: {
text: ''
},
xAxis: [{
categories: perfCategoriesStr
}],
yAxis: [
{ // Primary yAxis
labels: {
format: '{value}',
style: {
color: '#89A54E'
}
},
title: {
text: 'Views',
style: {
color: '#89A54E'
}
},
opposite:false
}, { // Secondary yAxis
title: {
text: 'Revenue in $',
style: {
color: '#4572A7'
}
},
labels: {
format: '{value}',
style: {
color: '#4572A7'
}
},
opposite: true
}, { // Secondary yAxis
title: {
text: 'eCPM in $',
style: {
color: '#4572A7'
}
},
labels: {
format: '{value}',
style: {
color: '#4572A7'
}
},
opposite: true
}],
tooltip: {
shared: true
},
legend: {
layout: 'vertical',
align: 'left',
x: 70,
verticalAlign: 'top',
y: 10,
floating: true,
backgroundColor: '#FFFFFF'
},
series: [{
name: 'Views',
color: '#4572A7',
type: 'column',
data: views,
tooltip: {
valueSuffix: ' views'
}
}, {
name: 'Revenue',
color: '#89A54E',
type: 'spline',
yAxis:1,
data: revenue,
tooltip: {
valuePrefix: '$ '
}
}, {
name: 'eCPM',
color: '#000000',
type: 'spline',
yAxis: 1,
data: ecpm,
tooltip: {
valuePrefix: '$ '
}
}]
});

Just figured it out. The values passed should be a number rather than a string. Its working fine if we are passing javascript numbers in an array instead of string as you can see in the question.

Convert the y-axis values to Millions in dual axis high charts

I am using dual-axis highcharts. In the y-axis the values are too big to read. I wold like to convert them to shortcuts like 1K for 1000 and 1.0L for 100000 and 1.0M for 1000000 and 35.8M for 35869982 and 3.5M for 3550977.

Here I have rounded up where I want to make changes in the below figure

You need to make a use of formatter:
formatter: function(){
return this.value/1000000 + "M";
}
Fiddle

To utilize the built in "shortening" functionality you can just remove your yAxis.label.format. You have currently set it to {value}, which is the default, but manually setting it seems to prevent the metric prefixes from being applied.
Look at this JSFiddle example, where all I've changed is removing the following line from both of your y-axis labels:
format: '{value}'
With this automatic shortening the following metric prefixes may be applied:
[ "k" , "M" , "G" , "T" , "P" , "E"]
You can set your own values with the lang.numericSymbols option (API).

I need help using a variable to populate a table to create a Javascript scatter plot

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">

var rateValueData = <?php echo json_encode($data);?>;
$(function (scatter) {
$('#container').highcharts({

},
subtitle: {

},
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: {

}
}
},
tooltip: {
headerFormat: '<b>{series.name}</b><br>',

}
}
},
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]];
