I'm new to chart.js, and I have a question about making x-axis labels position to the top.
This is the result that I expected: x-axis labels are on the top.
And this is my attempt:
const ctx = document.getElementById('weather_chart');
const myChart = new Chart(ctx, {
data: {
datasets: [{
type: 'bar',
label: 'rainfall probability',
data: [10, 20, 30, 40],
}, {
type: 'line',
label: 'temperature',
data: [50, 50, 50, 50],
borderColor: '#EB6E4B',
backgroundColor: '#EB6E4B',
}],
labels: ['now', '9am', '10am', '11am', '12pm'],
},
options: {
plugins: {
legend: {
display: false,
},
}
}
});<script src="https://cdn.jsdelivr.net/npm/chart.js"></script>
<div id="chart">
<canvas id="weather_chart"></canvas>
</div>If it is possible, would you take your time to write the answer?
Thanks in advance, and if my question is insufficient, I would appreciate it if you could tell me.
You can configure all scale related things like position in this namepsaces: options.scales[scaleId]. For more config options of the scales you can read the documentation: https://www.chartjs.org/docs/master/axes/
const ctx = document.getElementById('weather_chart');
const myChart = new Chart(ctx, {
data: {
datasets: [{
type: 'bar',
label: 'rainfall probability',
data: [10, 20, 30, 40],
}, {
type: 'line',
label: 'temperature',
data: [50, 50, 50, 50],
borderColor: '#EB6E4B',
backgroundColor: '#EB6E4B',
}],
labels: ['now', '9am', '10am', '11am', '12pm'],
},
options: {
scales: {
x: {
position: 'top'
}
},
plugins: {
legend: {
display: false,
},
}
}
});<script src="https://cdn.jsdelivr.net/npm/chart.js"></script>
<div id="chart">
<canvas id="weather_chart"></canvas>
</div>inside options > scales > xAxes the xAxes is an array, so we can define multiple axis and there configuration like this:
options:{
scales: {
xAxes: [
{
position: 'top',
ticks: {
maxRotation: 90,
minRotation: 80
}
}
]
}
}
