I'm trying to render a heatmap graphic but not all of yAxis are displayed in the chart, even putting turboThreshold to 0
My jsfiddle example:
http://jsfiddle.net/camilo17/zk70smv8/
My series array
series: [{
name: 'Trafico por horas',
borderWidth: 1,
data: [ ... ],
turboThreshold: 0,
}]
At the end of categories there is a "68" I don't know what does it means.
The simplest solution - set step label's property to 1.
labels: {
step: 1
}

Right off the bat here is the desired chart in ChartJS.
We have two x-axes. One showing power from a meter and the other showing meter state over time (open, closed, or in standby) In both datasets the X axis is Unix time. The power Y axis is numerical and the state x axis is one of the three state categories. Both are drawn in lines.
To get right to the point: how do I do this in Highcharts? I have the second axis set up:
xAxis: {
type: 'datetime'
},
yAxis: [
{
title: {
text: 'Real Power'
}
},
{
type: 'category', //I have also removed this line
title: {
text: 'state'
},
categories: ['closed', 'standby', 'open']
}
],
Any attempt to set the Y axis value to a string in highcharts results in a well known: https://www.highcharts.com/errors/14/
Furthermore online I only seem to find categories on the X axis. Any help getting to the right place is appreciated. Thanks in advance.
You can't use a string as x value, use a number instead, for example:
series: [{
...
}, {
...,
yAxis: 1,
data: [1, 0, 2, 1]
}],
yAxis: [{
...
}, {
title: {
text: 'state'
},
categories: ['closed', 'standby', 'open'],
min: 0,
max: 2
}]

I have this radar chart in chart.js which has 5 labels. The labels are quite long so I want to show them in two lines in HTML but when I use "\n" it doesn't make a new line!
These are my labels:
labels: ["COMMUNICATION \n SKILL ", "PRODUCT AND PROCESS \n KNOWLEDGE "]
As you can see I'm trying to have "communication skill" and "product and process knowledge" both in two lines but it shows them in one line!
What's the correct way to do it?
UPDATE
The labels is in script tag:
var myChart = new Chart(ctx, {
type: 'radar',
data: {
labels: ["COMMUNICATION SKILL ", "PRODUCT AND PROCESS KNOWLEDGE "],
datasets: [{
label: labs,
data: dps,
backgroundColor: [
'rgba(255, 99, 132, 0.2)'
],
borderColor: [
'rgba(255,99,132,1)',
],
borderWidth: 1
},
options: {
maintainAspectRatio: true,
scale: {
ticks:{
beginAtZero: true,
max: 4
}
}
}
});
I believe what you are looking for is answered here:
ChartJS New Lines '\n' in X axis Labels or Displaying More Information Around Chart or Tooltip with ChartJS V2
The solution is to pass a nested array as an input to 'labels' - with each element in the nested array representing a new line of text in your label. So in your case the following should work:
labels: [["COMMUNICATION","SKILL"], ["PRODUCT AND PROCESS","KNOWLEDGE"]]
Just read the docs https://www.chartjs.org/docs/latest/charts/radar.html
you need your dataset to have the property data and that should be an array. The values in the array will correspond with the values in the labels by their index number.
data: {
labels: ['Running', 'Swimming', 'Eating', 'Cycling'],
datasets: [{
data: [20, 10, 4, 2]
}]
}
I am implementing a Sankey Diagram using Highcharts JS and have a problem with specifying the axis. Is it even possible to use xAxis and yAxis on a Sankey diagram?
I tried specifying the axis as following:
yAxis: {
title: {
text: 'Test',
}
},
xAxis: {
title: {
text: 'Test'
}
},
but with no success. I tried putting the aforementioned code in series, plotOptions.sankey, plotOptions.series and simply when instantiating the chart but with no result.
Looking forward to your help!
Yes. Use chart.showAxes option:
chart: {
showAxes: true
},
Unfortunately in sankey series ticks are not generated for the y axis. It can be done manually like this:
yAxis: [{
lineWidth: 1,
tickPositions: [0, 1, 2, 3]
}],

I need to convert this Highcharts.JS chart to C3.JS chart
http://i.imgur.com/iwk3pyO.png
This was the Highcharts.JS code:
var chart = new Highcharts.Chart({
xAxis: {
title: {
text: 'Values'
}
},
yAxis: {
title: {
text: ' Frequency',
align: 'high',
offset: 23
}
},
legend: {
enabled: false
},
tooltip: {
enabled: false
},
series: [
{
data: []
}
]
});
Upon converting to C3.JS, I encounter a problem with the x-values. The bar chart of C3.JS, by default, assigns values to each bar as 0, 1, 2, ... n instead of the values that I wanted which is the following:
var xData = [0.1384261, 0.2337903, 0.3291545, 0.4245187, 0.5198829, 0.6152470999999999, 0.7106113000000001, 0.8059755, 0.9013397000000001, 0.9967039];
I tried to somehow "trick" it to show the x values as labels but the problem here is the red region at the back. I set the region to be displayed in 0 to 1 values but you'll notice in C3.JS that the region is place in the first and second bars instead of after the last graph since its value is less than 1.

Maybe a little bit late, but in case someone still needs it (or to use numerical X axis in bar chart). Here is an idea:
Instead of
regions: [
{start: 0, end: 1, class: 'red-color'}
]
You need to hack the end value according to how many items are less than 1 in your categories?. You code would be probably like this:
function fctGetItemLessThan1(xData){
//implement your count logic here + return value
}
then in your chart option:
...
regions: [
{start: fctGetItemLessThan1() - 1, end: fctGetItemLessThan1(), class: 'red-color'}
]
...
In your case, fctGetItemLessThan1() - 1 = 9, the result is as follow
Is it possible to have 2 yAxis in a highstock chart from highcharts one on the left and another on the right ?
Thanks
A very simple example:
First you have to create your new yAxis and set it's position.
{
title: {
text: 'Other data panel'
},
top: 300,
height: 100,
offset: 0,
lineWidth: 2,
opposite: true
}
Then, when you create your serie you in what yAxis it will be placed.
{
type: 'column',
name: 'Other',
data: otherData,
yAxis: 2,
dataGrouping: {
units: groupingUnits
}
}
You can see it working here.
