I am attempting to graph like numbers on posts and when they were posted. For some reason it goes crazy if points are close. Any ideas why?
I have been playing a little bit with the step sizes as well as the x axis' dynamic stretching, but to no avail.
var myLine2 = new Chart(ctx2, {
type: 'line',
data: {
//labels: '{{ labels | tojson }}',
datasets: [{
label: 'My Line',
data: data,
lineTension: 0
}]
},
options: {
//spanGaps: true,
scales: {
xAxes: [{
type: 'time',
time: {
//unit: 'day',
tooltipFormat: 'lll',
}
}]
}
}
});
Here is what it looks like: https://ibb.co/Fgq6M8M (I don't have enough reputation to upload images)
I expect the line to connect to the closest point to the right, but it actually darts around the chart. Any thought?

Chart.js draws your data points in the order they are specified. The drawing of a single data point is not independent from the other data points. Instead, a line is drawn from point to point, in the order specified in the dataset.
An excerpt from your provided dataset shows that the x axis is not in ascending order.

46: {x: Sun Jun 09 2019 16:44:17 GMT+1000 (Australian Eastern Standard Time), y: "80"}
47: {x: Wed May 22 2019 09:20:12 GMT+1000 (Australian Eastern Standard Time), y: "59"}
48: {x: Mon Jun 10 2019 06:12:26 GMT+1000 (Australian Eastern Standard Time), y: "9"}
To fix this, make sure the data points are ordered before they are passed to Chart.js.
