Scott,
intervalType defaults to “number” when you set the interval. If you prefer interval to be 1 day, set intervalType to "day" along with setting interval to 1.
Check this code.
var chart = new CanvasJS.Chart("chartContainer", {
zoomEnabled: false,
animationEnabled: false,
title: {
text: "BJS Site Record Item QTY"
},
axisY2: {
valueFormatString: "0",
maximum: 50,
interval: 5,
interlacedColor: "#F5F5F5",
gridColor: "#D7D7D7",
tickColor: "#D7D7D7"
},
axisX: {
//title: "BJS Site Record Item QTY",
interval: 1,
intervalType: "day"
},
theme: "theme2",
toolTip: {
shared: true
},
legend: {
verticalAlign: "bottom",
horizontalAlign: "center",
fontSize: 15,
fontFamily: "Lucida Sans Unicode"
},

ChartJS: How to center monthly bars against a daily line chart?

I'm trying to display total monthly sales and daily stock level. This way you could easily see that you didn't have any sales a particular month because you had low stock. Monthly sales is a bar chart that should be in the center of each month (in between the ticks).
In order to get it close to the middle my data is using the 15th of each month as the date to center it. I would want to know if there is a better way to achieve this?
JSFiddle to play around with: https://jsfiddle.net/8Lydhpqc/3/
const dailyStock = [
{ x: "2017-08-02", y: 1 },
{ x: "2017-08-25", y: 3 },
{ x: "2017-09-10", y: 7 },
{ x: "2017-09-28", y: 0 },
{ x: "2017-10-02", y: 3 },
{ x: "2017-10-24", y: 2 },
{ x: "2017-11-01", y: 1 },
{ x: "2017-11-30", y: 0 },
];
//using the 15th of each month to center it
const monthlyTotal = [
{ x: "2017-08-15", y: 1 },
{ x: "2017-09-15", y: 10 },
{ x: "2017-10-15", y: 5 },
{ x: "2017-11-15", y: 5 },
];
var ctx = document.getElementById("myChart").getContext("2d");
var myChart = new Chart(ctx, {

Welcome to Stackoverflow!
It seems that there is a way better than using the 15th of the month.
You need to add another axis for the bar that is a category type axis. Also its pretty critical that you have "offset: true" on that axis as well. Otherwise it will not center.
In the code below I named that category "bar" and the existing one "line"
I also created a fiddle: https://jsfiddle.net/jyf8ax3e/
var myChart = new Chart(ctx, {
type: "bar",
data: {
labels: ["2017-08", "2017-09", "2017-10", "2017-11"],
datasets: [
{
barPercentage: .7,
xAxisID: "bar",
label: "sales",
data: monthlyTotal,
backgroundColor: "green",
borderColor: "black",
borderWidth: 1,
width: 55,
order: 2,
},
{
label: "stock",
type: "line",
data: dailyStock,
backgroundColor: "orange",
borderColor: "orange",
fill: false,
order: 1,
},
],
},
options: {
scales: {
xAxes: [
{
id: "line",
type: "time",
time: {
unit: "month",
displayFormats: {
month: "MMM",
},
},
distribution: "linear",
},
{
id: "bar",
offset: true,
type: "category",

How to pass data in Laravel with Chart.js

I want to display total of men and woman from learnings table in chart using Chartjs in Laravel.
My controller
public function index()
{
$men_learning = DB::table('learnings')->where('active', 1)->whereYear('created_at', $year)->sum('men');
$women_learning = DB::table('learnings')->where('active', 1)->whereYear('created_at', $year)->sum('women');
$learning = $men_learning + $women_learning ;
return view('home', compact('learning'));
}
My script in blade view.
<script>
var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: ['total'],
datasets: [{
label: '# of Votes',
data: [12],
backgroundColor: [
'rgba(255, 99, 132, 0.2)',

borderWidth: 1
}]
},
options: {
scales: {
yAxes: [{

}
}
});

How can I propagate loaded statistic from my script to the chart?

How to configure linear labels in Time Cartesian Chartjs?

I need to show labels on the x-axis every 2 hours (0h, 2h, 4h...). What am I missing?
<script>
var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
type: 'line',
data: {
//labels: ['0h', '2h', '4h', '6h', '8h', '10h', '12h', '14h', '16h', '18h', '20h', '22h', '0h'],
datasets: [{
label: 'AAA1111',
//xAxisID: 'Hora',
//yAxisID: 'Velocidade',
data: [{
t: new Date("2015-3-15 12:30"),
y: 12
},
{
t: new Date("2015-3-15 14:40"),
y: 45
},
{
t: new Date("2015-3-15 17:50"),
y: 77
}
],
borderColor: 'rgba(255, 0, 0, 1)',
borderWidth: 4,
fill: false,
lineTension: 0,
lineJoint: "round",
spanGaps: true
}]
},
options: {
scales: {
xAxes: [{
type: 'time',
distribution: 'linear',
time: {
unit: 'hour',
//stepSize: 24??
},
ticks: {
source: 'data'
}
}]
}
}
});
</script>
The chart plots Time x Velocity.
Two small changes will achieve the desired result:
set stepSize: 2 to 'show labels on X axis every 2 hours (0h, 2h, 4h...)'
remove ticks: { source: 'data' } as that:
generates ticks from data (including labels from data {t|x|y} objects)"
Here's a working example based on the posted code:
var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
type: 'line',
data: {
//labels: ['0h', '2h', '4h', '6h', '8h', '10h', '12h', '14h', '16h', '18h', '20h', '22h', '0h'],
datasets: [{
label: 'AAA1111',
//xAxisID: 'Hora',
//yAxisID: 'Velocidade',
data: [{
t: new Date("2015-3-15 12:30"),
y: 12
},
{
t: new Date("2015-3-15 14:40"),
y: 45
},
{
t: new Date("2015-3-15 17:50"),
y: 77
}
],
borderColor: 'rgba(255, 0, 0, 1)',
borderWidth: 4,
fill: false,
lineTension: 0,
lineJoint: "round",
spanGaps: true
}]
},
options: {
scales: {
xAxes: [{
type: 'time',
distribution: 'linear',
time: {
unit: 'hour',
stepSize: 2

}
}

set bar width- kendo bar chart using gap and spacing?

I need some help to set the width of the bars in kendo bar charts when the number of bars reduces.
Here is the jsFiddle link i am working on: http://jsfiddle.net/An59E/44/
In this example, there are 2 kendo bar charts, 1 has 6 bars and the other has 12 bars.
In the second graph the bars width is fine. Now when i remove 2 bars i need the same width of bars, instead the default behavior of the kendo is to resize bars. by setting the spacing and the gap values, the bars should resize. In this example, i have set the spacing and gaps value in series defaults attribute but it doesn't look like its working. Now the question is , how to change the width of the bars?

Thanks.
just replace below code snippet in javascript and you are done!
seriesDefaults:
{
type: "column",
labels:
{
visible: true,
color: "green"
},
gap: 5,
},
In above code I have added gap value to define gap of bars which leads to make them thin which you want.
Please refer to below js fiddle.

Please let me know if you face any difficulty to implement the same.

Kendo bar chart- plot band in both the panes

I have a bar chart with 2 panes. I want to add plot bands in both the panes but with different color. How can this be done?
And i want to display the categories labels at the bottom of the graph. how can this be done?

Thanks.
To add plot bands in both the panes:
plotBands: [
{
from: 95,
to: 100,
color: "#2082c8"
//color: "url(#pattern2)",
},
{
from: 125,

color: "#c82020"
}
