Answer 1

You can obtain the desired result by defining a second y-axis as follows:
{
type: 'category',
position: 'right',
offset: true,
ticks: {
reverse: true,
},
gridLines: {
display: false
}
}
Please take a look at your amended and runnable code below:
new Chart(document.getElementById('canvas'), {
type: 'horizontalBar',
data: {
labels: ['0-4', '5-9', '10-14', '15-19', '20+'],
datasets: [{
label: 'Pasien Masuk',
data: [100, 90, 80, 70, 60],
backgroundColor: 'red',
},
{
label: 'Pasien Keluar',
data: [-100, -75, -60, -75, -70],
backgroundColor: 'blue',
},
]
},
options: {
responsive: true,
title: {
display: true,
text: 'Data Pasien Keluar Masuk',
fontSize: 20,
},
legend: {
position: 'bottom',
},
tooltips: {
callbacks: {
label: (tooltipItem, data) => {
let ds = data.datasets[tooltipItem.datasetIndex];
return ds.label + ': ' + Math.abs( ds.data[tooltipItem.index]);
}
}
},
scales: {
xAxes: [{
stacked: true,
ticks: {
callback: value => Math.abs(value)
}
}],
yAxes: [{
stacked: true,
ticks: {
reverse: true,
}
},
{
type: 'category',
position: 'right',
offset: true,
ticks: {
reverse: true,
},
gridLines: {
display: false
}
}]
}
}
});
