I want to do an horizontal bar with 2 yaxes, Where a bar can have a positive or negative value and positive side has a yaxis and the negative side has other yaxis like the image
This is my code JSFiddle.
I can't change the names of the second yaxes
I add arrays with the same values because i would want two yaxes, It is not necessary to use "chart.js" if you knows other library where i can it use, please tell me
var canvas = document.getElementById('myChart');
var extremo1=[-5, 3, 9, -11];
var extremo2=[-5, 3, 9, -11];
var data = {
labels: ["Visua_Verbal", "Secuencial_Global", "Sensitivo_Intuitivo", "Reflexivo_Activo"],
datasets: [
{
backgroundColor: 'rgba(63, 191, 191, 0.75)',
borderColor: 'rgba(63, 191, 191, 0.75)',
hoverBackgroundColor: 'rgba(191, 63, 63, 1)',
hoverBorderColor: 'rgba(191, 63, 63, 1)',
data: extremo1
},
{
backgroundColor: 'rgba(63, 191, 191, 0.75)',
borderColor: 'rgba(63, 191, 191, 0.75)',
hoverBackgroundColor: 'rgba(191, 63, 63, 1)',
hoverBorderColor: 'rgba(191, 63, 63, 1)',
data: extremo1
}
]
};
var option = {
maintainAspectRatio: false,
responsive: true,
scales: {
xAxes: [{
display: true,
ticks: {
maxTicksLimit: 12
}
}],
yAxes: [{
position: "left",
display: true,
ticks: {
callback:(label,index,labels)=>{
label = label.match(/_(\w*)/)[1];
return label;
}}
},
{
position: "right",
display: true,
ticks: {
callback:(label,index,labels)=>{
return label ;
}
}
}]
},
legend: {
display: false
}
};
var myLineChart = new Chart(canvas,{
type: 'horizontalBar',
data:data,
options:option
});

In the snippet below I've set the options labels
, type
, offset
on the y-axes to achieve the result you want. I've also removed unnecessary properties.
var canvas = document.getElementById('myChart');
var extremo = [-5, 3, 9, -11];
var data = {
datasets: [{
backgroundColor: 'rgba(63, 191, 191, 0.75)',
borderColor: 'rgba(63, 191, 191, 0.75)',
hoverBackgroundColor: 'rgba(191, 63, 63, 1)',
hoverBorderColor: 'rgba(191, 63, 63, 1)',
data: extremo
}]
};
var option = {
maintainAspectRatio: false,
responsive: true,
scales: {
xAxes: [{
ticks: {
maxTicksLimit: 12
}
}],
yAxes: [{
labels: ['Verbal', 'Global', 'Reflexivo', 'Sensitivo']
},
{
position: 'right',
labels: ['Visual', 'Secuencial', 'Activo', 'Intuitivo'],
gridLines: {
display: false
},
type: 'category',
offset: true
}
]
},
legend: {
display: false
}
};
var myLineChart = new Chart(canvas, {
type: 'horizontalBar',
data: data,
options: option
});
