You can do it by defining the min
and max
values under the time
key.
If
min
ormax
is defined, this will override the data minimum or maximum respectively. See docs for more info.
chartHour.config.options.scales.xAxes[0] = {
type: "time",
time: {
min: "2017-01-01",
max: "2017-12-01",
displayFormats: {
day: "MMM YY"
}
}
};
See working example below.
const months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
const years = [2016, 2017, 2018];
const labels = [];
const dataSet = [];
years.forEach((year, index) => {
months.forEach((month, monthIndex) => {
const date = moment(`${month} ${year}`, "MMM YYYY").format('YYYY-MM-DD');
labels.push(date);
dataSet.push({
x: date,
y: (monthIndex + 12) * (index + 1)
});
});
});
var data = {
labels: labels,
datasets: [{
pointRadius: 0,
label: "Positive",
lineTension: 0,
data: dataSet,
borderWidth: 1,
backgroundColor: "rgba(0, 255, 0, 0.5)"
}]
};
var options = {
scales: {
xAxes: [{
type: "time",
distribution: 'series',
time: {
min: "2017-01-01",
max: "2017-12-01",
displayFormats: {
day: 'MMM YY'
}
},
ticks: {
source: "labels"
},
gridLines: {
display: false
}
}]
}
};
var ctx = document.getElementById("myChart").getContext("2d");
var myBarChart = new Chart(ctx, {
type: "bar",
data: data,
options: options
});
