I am fairly new to javascript world, so bear with me if there is an obvious solution to this, but I'm struggling to graph the dates (X-points) on the X axis of the chartjs graph. I get some weird times there that you can check on jsfiddle. What am I doing wrong?
var ctx = document.getElementById("myChart");
var data = {
datasets: [{
label: " Property",
lineTension: 0.1,
data: [{
x: 2017 - 04 - 11,
y: 2000000.00
},
{
x: 2017 - 04 - 12,
y: 1000000.00
},
{
x: 2017 - 04 - 13,
y: 3000000.00
},
]
},
{
label: " Property",
lineTension: 0.1,
data: [{
x: 2017 - 04 - 12,
y: 472943.00
},
{
x: 2017 - 04 - 13,
y: 1000000.00
},
]
},
]
};
var myLineChart = new Chart(ctx, {
type: 'line',
data: data,
options: {
scales: {
xAxes: [{
id: 'ScartCharxAxes',
type: 'time',
unit: 'day',
time: {
displayFormats: {
day: 'D MMM YYYY'
},
}
}]
}
}
});
My code is available on http://jsfiddle.net/py1bpf02/3/

In your datasets, dates should be strings. What you did is math, not dates. 2017-04-11 = 2002
.
var ctx = document.getElementById("myChart");
var data = {
datasets: [
{
label: " Property",
lineTension: 0.1,
data: [{
x: "2017-04-11",
y: 2000000.00
},
{
x: "2017-04-12",
y: 1000000.00
},
{
x: "2017-04-13",
y: 3000000.00
},
]
},
{
label: " Property",
lineTension: 0.1,
data: [{
x: "2017-04-12",
y: 472943.00
},
{
x: "2017-04-13",
y: 1000000.00
},
]
},
]
};
var myLineChart = new Chart(ctx, {
type: 'line',
data: data,
options: {
scales: {
xAxes: [{
id: 'ScartCharxAxes',
type: 'time',
time: {
unit: 'day',
displayFormats: {
day: 'D MMM'
},
}
}]
}
}
});
