I'm making a chart here and I have a little problem with removing the distance between the boxes
var myConfig = {
type: 'bar',
legend: {
layout: "x4",
overflow : "page",
shadow : false,
align : "left",
alpha :0.05,
"adjust-layout": true,
marker : {
type : "circle",
size : "7px",
"border-color" :"none"
}
},
scaleX: {
// convert text on scale indices
labels: ['Automotive', 'Retail', 'Wholesale']
},
plot: {
barWidth:"50%",
animation: {
effect: 'ANIMATION_EXPAND_BOTTOM',
method: 'ANIMATION_STRONG_EASE_OUT',
sequence: 'ANIMATION_BY_NODE',
speed: 275,
}
},
series: [
{
// plot 1 values, linear data
values: [23, 20, 27],
text: 'Sum of target Premi',
backgroundColor: '#fa6383',
borderRadius: 5,
},
{
// plot 2 values, linear data
values: [35, 42, 33],
text: 'Sum of premi Leads',
backgroundColor: '#fb9f40',
borderRadius: 5,
},
{
// plot 2 values, linear data
values: [15, 22, 13],
text: 'Sum of premi Activity',
backgroundColor: '#fdcd55',
borderRadius: 5,
},
{
// plot 2 values, linear data
values: [15, 22, 13],
text: 'Sum of premi Booking',
backgroundColor: '#4bc0c1',
borderRadius: 5,
}
]
};
for my settings like this. there are suggestions so there can be no space ?
i have try documentation but does not work.

I'm not sure that I correctly understood your problem but probably you can try to use "barsOverlap" in "plot" configuration to achieve the desired result.
var myConfig = {
type: 'bar',
legend: {
layout: "x4",
overflow : "page",
shadow : false,
align : "left",
alpha :0.05,
"adjust-layout": true,
marker : {
type : "circle",
size : "7px",
"border-color" :"none"
}
},
scaleX: {
// convert text on scale indices
labels: ['Automotive', 'Retail', 'Wholesale']
},
plot: {
barWidth:"50%",
barsOverlap: '50%',
animation: {
effect: 'ANIMATION_EXPAND_BOTTOM',
method: 'ANIMATION_STRONG_EASE_OUT',
sequence: 'ANIMATION_BY_NODE',
speed: 275,
}
},
series: [
{
// plot 1 values, linear data
values: [23, 20, 27],
text: 'Sum of target Premi',
backgroundColor: '#fa6383',
borderRadius: 5,
},
{
// plot 2 values, linear data
values: [35, 42, 33],
text: 'Sum of premi Leads',
backgroundColor: '#fb9f40',
borderRadius: 5,
},
{
// plot 2 values, linear data
values: [15, 22, 13],
text: 'Sum of premi Activity',
backgroundColor: '#fdcd55',
borderRadius: 5,
},
{
// plot 2 values, linear data
values: [15, 22, 13],
text: 'Sum of premi Booking',
backgroundColor: '#4bc0c1',
borderRadius: 5,
}
]
};
I'm trying to make a Chart.js with a dynamic x-axis that will always use the next 7 months as the ticks for the x-axis.
But I'm having two problems:
The lines are not showing on my graph
The x-axis is only showing the first and last month, none of the months in-between.
Here is an example I made in paint to show what I'm trying to achieve:
And here is the code I have so far:
/* Build the charts */
var ctx = document.getElementById('ROIchart').getContext('2d');
var chart = new Chart(ctx, {
// The type of chart we want to create
type: 'line',
// The data for our dataset
data: {
datasets: [{
label: 'Paid Search and Leads',
backgroundColor: 'red',
borderColor: 'red',
data: [10, 10, 10, 10, 10, 10, 10],
}, {
label: 'SEO and Content',
backgroundColor: 'green',
borderColor: 'green',
data: [0, 2, 8, 21, 57, 77, 100],
fill: true,
}]
},
// Configuration options go here
options: {
responsive: true,
scales: {
xAxes: [{
type: 'time',
time: {
unit: 'month'
}
}]
}
}
});

<canvas id="ROIchart"></canvas>
With the moment.js library, you can look at the length of your array, and from a starting month generate the months, and then put them as labels
/* Build the charts */
var ctx = document.getElementById('ROIchart').getContext('2d');
var array1 = [10, 10, 10, 10, 10, 10, 10];
var months = []
for (let i = 0; i < array1.length; i++) {
months.push(moment().year(2020).month(i+1).date(0).startOf('month'))
}
var chart = new Chart(ctx, {
type: 'line',
data: {
labels: months,
datasets: [{
label: 'Paid Search and Leads',
backgroundColor: 'red',
borderColor: 'red',
data: array1,
}, {
label: 'SEO and Content',
backgroundColor: 'green',
borderColor: 'green',
data: [0, 2, 8, 21, 57, 77, 100],
fill: true,
}]
},
options: {
responsive: true,
scales: {
xAxes: [{
type: 'time',
time: {
unit: 'month'
}
}]
}
}
});

I'm doing an app that displays daily personal work data.
I store the data in an array called "dailyTimePerProjectPerWeek", for now I define the data for 3 weeks.
I have placed two buttons in the html, "Previous Week" and "Next Week", to navigate between the weeks.
When the page is loaded for the first time it shows the most recent week corresponding to the highest index of the array mentioned above.
The problem is that it does something strange to me to visualize the data, it's like that I created several charts.
How can I refresh the image of the chart properly?
There goes my html code:
<!DOCTYPE html>
<html lang="en" >
<head>
<meta charset="UTF-8">
<title>Charts4DailyProgress</title>
<link rel="stylesheet" href="css/style.css">
</head>
<body>
<body>
<h1>Weekly Time per Project</h1>
<div id="canvas-container">
<canvas id="ctx" width="1000"></canvas>
<button type="button" onclick="decrementWeek()">Previous Week</button>
<button type="button" onclick="incrementWeek()">Next Week</button>
</div>

var currentWeek = dailyTimePerProjectPerWeek.length - 1;
var weekValue = currentWeek; //At first time weekValue points to the current week
function drawData(){
var chart = new Chart(ctx, {
type: 'bar',
data: dailyTimePerProjectPerWeek[weekValue],
options: {
responsive: false,
legend: {
position: 'right' // place legend on the right side of chart
},

}
}
});
}
function incrementWeek(){
if(weekValue === dailyTimePerProjectPerWeek.length - 1){
console.log("This is the current week");
} else {
weekValue += 1;
drawData();
}
}
function decrementWeek(){
if(weekValue === 0){
console.log("This is the oldest week of the time series");
} else {

//Main Program
var chart = new Chart(ctx, {
type: 'bar',
data: dailyTimePerProjectPerWeek[weekValue],
options: {
responsive: false,
legend: {
position: 'right' // place legend on the right side of chart
},
scales: {
xAxes: [{
stacked: true // this should be set to make the bars stacked
}],
yAxes: [{
stacked: true // this also..
}]
}
}
});
The truth is that I use the following code to try to refresh the image:
function drawData(){
var chart = new Chart(ctx, {
type: 'bar',
data: dailyTimePerProjectPerWeek[weekValue],
options: {
responsive: false,
legend: {
position: 'right' // place legend on the right side of chart
},
scales: {
xAxes: [{
stacked: true // this should be set to make the bars stacked
}],
yAxes: [{
stacked: true // this also..
}]
}
}
});
}
Change your drawData() function to:
function drawData() {
chart.data = dailyTimePerProjectPerWeek[weekValue];
chart.update();
}
I am trying to take a chartJS doughnut chart and instead of it displaying each piece of data on a single dataset I want each unique piece of data (with its own unique label) to display on its own dataset. This means to represent that data on each dataset it still needs two pieces of data:
- the desired value (ie. 80%)
- the difference value (ie. 20%)
After some research I figured out how to use callback function to display the dataset label to each of its data values and add a percentage character after its number value. Now I am trying to hide the tooltip for the second data value within each dataset. I am new to javascript so a little help would be appreciated! Cheers.

those data-sets in chart.js don't work alike series in other charts do, but are index-based. therefore you'd require only two datasets and then you'd have to map those values accordingly; so that index position 0, 1, 2, 3, ... on both of the data arrays, would sum up to 100.
