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)',
],
borderColor: [
'rgba(255, 99, 132, 1)',
],
borderWidth: 1
}]
},
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero: true
}
}]
}
}
});
</script>
How can I propagate loaded statistic from my script to the chart?
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');
return view('home', compact('men_learning', 'women_learning'));
}
<script type="text/javascript">
$(function(){
var ctx = document.getElementById("myChart").getContext('2d');
var myChart = new Chart(ctx, {
type: 'bar',
data: {

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,

lineJoint: "round",
spanGaps: true
}]
},

I have created a chart with Chart.js, and I now need to show the data in the legend differently per the two different datasets.
How do I show the first dataset 'Low/High Range Limit' in the classic rectangle/fill style and the dataset 'Patient Results' in the point style?
(Bonus: Currently, I'm showing the second dataset near-correctly. I also want to completely fill the circle with the solid 'steelblue' color, not with transparency.)
(I would provide an image but I need at least 10 reputation to post them.)

I am developing a django app using the Django Rest Framework with chart.JS in order to render some chart.
My ajax call is taking a long long long time and I am on local..
Is there a way to check what is taking so long in order to know where to look in order to refactor ?
it takes on average on local between 10 and 15 second each time..
Here is my code for example:
<script>
var endpoint = 'api/chart/data2'
$('.ajaxProgress').show();
$('.dashboard-container').hide();
function getAvg(grades) {
return grades.reduce(function (p, c) {
return p + c;
}) / grades.length;
}
$.ajax({
method: "GET",
url: endpoint,
success: function(data){
console.log(data)
complete_data = data.team_complete,

You can test you django api using postman. You will get the execution time there.
Also if you want to profile your django app you can refer the following link profiling django
I use canvasJS to paint chart,but when the page change different window, the X axis will show different. when page open in little window show right like this enter image description here,but when page show big window show wrong like thisenter image description here

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.
