I am trying to use ChartJS to draw a chart showing different statuses (On/Off) of a device during a specific time period.
The X-Axis represents the date and time, and the Y-Axis represents the status (1-On, 0-Off).
My only problem is that the distance between 2 subsequent points on X-Axis is constant and not presenting the "real" distance between the two date-times.
For example, the distance between a point, and another point which is a second later is the same as the distance between a point and another point which is a day later.
Here is the code:
var ctx = document.getElementById('myChart').getContext('2d');
var chart = new Chart(ctx, {
// The type of chart we want to create
type: 'line',
// The data for our dataset
data: {
labels: [
new Date("2019-03-31T17:41:02.517839+00:00"),new Date("2019-03-31T17:41:13.969037+00:00"),new Date("2019-03-31T17:41:22.568130+00:00"),new Date("2019-03-31T17:41:23.568130+00:00"),new Date("2019-03-31T17:41:34.010461+00:00"),new Date("2019-03-31T17:41:35.010461+00:00"),new Date("2019-03-31T17:41:55.353745+00:00"),new Date("2019-03-31T17:41:56.353745+00:00"),new Date("2019-03-31T17:42:04.254075+00:00"),new Date("2019-03-31T17:42:05.254075+00:00"),new Date("2019-03-31T17:42:15.552743+00:00"),new Date("2019-03-31T17:42:25.306603+00:00"),new Date("2019-03-31T17:42:26.306603+00:00"),new Date("2019-03-31T17:43:13.747931+00:00"),new Date("2019-03-31T17:43:14.747931+00:00"),new Date("2019-03-31T18:03:46.567253+00:00"),new Date("2019-03-31T18:03:47.567253+00:00"),new Date("2019-03-31T18:30:38.945956+00:00"),new Date("2019-03-31T18:30:39.945956+00:00"),new Date("2019-03-31T18:45:10.718018+00:00"),new Date("2019-03-31T18:45:11.718018+00:00"),new Date("2019-03-31T19:51:24.369067+00:00"),new Date("2019-03-31T19:51:25.369067+00:00"),new Date("2019-03-31T19:53:40.861770+00:00"),new Date("2019-03-31T19:53:41.861770+00:00"),
],
datasets: [{
label: 'Activity',
backgroundColor: 'rgba(30,140,50,0.5)',
borderColor: 'rgba(30,140,50,0.5)',
data: [
1, 1, 1, 0, 0, 1, 1, 0, 0, 1, 1, 1, 0, 0, 1, 1, 0, 0, 1, 1, 0,
]
}]
},
// Configuration options go here
options: {
scales: {
xAxes: [{
display: false,
}],
yAxes: [{
display: false,
}],
},
elements: {
line: {
tension: 0
}
},
}
and here is how it looks like:
Can you please help with that?
Thanks!
