above are all the labels that I want to show on the graph but it hiding all the odd index values from the graph only showing even index values on the graph from the above list.
see the graph it missing some labels.
if you see the order all the even number index values are displayed and odd are hidden..
This is all my chart code...

}
}
}
};
const ctx = document.querySelector(`#chart${index+1}`).getContext('2d');
const myChart = new Chart(ctx, config)
I have also tried..
x:{ticks:{autoSkip:false}}
when I do this it changes my label to numbers..
when you are using the type:"scatter",
Scatter charts are based on basic line charts with the x axis changed to a linear axis. To use a scatter chart, data must be passed as objects containing X and Y properties. The example below creates a scatter chart with 4 pointslink for charts scatter charts
when you are not defining the values with x and y then used the x-axis and y-axis as linear and then you can manipulate the x-axes for both line and bar..if you will not provide the chart_type in config it will take axes as linear
you can
xAxisID: 'x-axis-bar',
xAxisID: 'x-axis-line',
and then hide the 1 x-axis and autoSkip=False it will show your all values.

i'd like exact sime of it
and here is mine:
days should be in a ratio of 356 and i cant handle it
which config setting for ticks handles this i tried stepsize bu it seems like it didnt work
at right there is estimated section as you see can it be added by js or do i have to use css this one is css form
Problem: Hi all! i am using chart.js to draw the charts. chart is a dynamic sometimes shows 10 points and sometimes can be more than thousand i have applied a panel successfully so that my points can be shown at some distance to read them easily.
Right now i want to know if there is any option to set the distance between points in x-axis grid. right now it automatically adjust the points.
What i tried:
i tried to do the stepsize and scalewidth by searching other stackoverflow answers but did not succeed. Any kind of help would be much appreciated.
P.S: i m using chart.js2
This is my chartjs dataset

}
}

}

if(new_chart[ctx.canvas.id] != null)
new_chart[ctx.canvas.id].destroy();
new_chart[ctx.canvas.id] =new Chart(ctx, {
type: 'line',
data: data,
options: options
});
In x-axis there is data like this
[19-Aug-2015,21-Aug-2015,21-Aug-2015,21-Aug-2015,21-Aug-2015,22-Aug-2015,27-Aug-2015,29-Aug-2015,1-Sep-2015,2-Sep-2015,3-Sep-2015,]
in y-axis data is like this
[0.1,0.05,0.89,0.89,0.79,0.58,0.68,0.25,0.98]
The way to control distance between points it to set the X and Y axis with a min, max, and step size so that they never change regardless of the number of points that are in the chart.
Here is an example that sets the scales so that they will never change. Regardless of how many points appear on the chart everything will stay the same.
var ctx = document.getElementById("myChart");
var myChart = new Chart(ctx, {
type: 'line',
data: {
datasets: [{
label: 'Points',
data: [
{x: 0, y: 2},
{x: 1, y: 3},
{x: 2, y: 2},
{x: 1.02, y: 0.4},
{x: 0, y: -1}
],
backgroundColor: 'rgba(123, 83, 252, 0.8)',
borderColor: 'rgba(33, 232, 234, 1)',
borderWidth: 1,
fill: false,
showLine: false,
}],
},
options: {
title: {
display: true,
text: 'Chart.js - Fixed X and Y Axis',
},
scales: {
xAxes: [{
type: 'linear',
position: 'bottom',
ticks: {
min: -1,
max: 8,
stepSize: 1,
fixedStepSize: 1,
}
}],
yAxes: [{
ticks: {
min: -2,
max: 4,
stepSize: 1,
fixedStepSize: 1,
}
}]
}
}
});
Here is a codepen example that demonstrates what this looks like
I'm trying to display a line chart on a webpage using Chart.js that shows the number of downloads in the apple store and google play store for a specific client for the past 5 days. The data appears properly, but does not properly label the X axis with this:
var downloadsChartData = {
labels: ["4 Days", "3 Days", "2 Days", "Yesterday", "Today"],
datasets: [{
label: "Google Play",
fill: false,
lineTension: 0,
backgroundColor: "rgba(0, 230, 115, 1)",
borderColor: "rgba(0, 230, 115, 1)",
borderCapStyle: 'butt',
borderJoinStyle: 'miter',
borderWidth: 2,
pointBorderColor: "rgba(150, 75, 75, 1)",
pointBorderWidth: 3,
pointRadius: 6,
pointHoverRadius: 9,
pointStyle: 'triangle',
data: [{
x: 1,
y: 2
}, {
x: 2,
y: 0
}, {
x: 3,
y: 3
}, {
x: 4,
y: 1
}, {
x: 5,
y: 1
}]
}, {
label: "iOS",
fill: false,
lineTension: 0,
backgroundColor: "rgba(26, 117, 255, 1)",
borderColor: "rgba(26, 117, 225, 1)",
borderCapStyle: 'butt',
borderJoinStyle: 'miter',
borderWidth: 2,
pointBorderColor: "rgba(150, 75, 75, 1)",
pointBorderWidth: 3,
pointRadius: 6,
pointHoverRadius: 9,
data: [{
x: 1,
y: 4
}, {
x: 2,
y: 2
}, {
x: 3,
y: 0
}, {
x: 4,
y: 1
}, {
x: 5,
y: 4
}]
}]
};
var downloadsChartOptions = {
title: {
display: true,
text: 'Downloads on Google Play and App Store',
fontSize: 30
},
scales: {
xAxes: [{
scaleLabel: {
display: true,
abelString: 'Date',
fontSize: 20
},
type: 'linear',
position: 'bottom',
gridLines: {
display: false
}
}],
yAxes: [{
scaleLabel: {
display: true,
labelString: 'Downloads',
fontSize: 20
}
}]
}
};
var downloadsChart = document.getElementById('downloadsChart').getContext('2d');
new Chart(downloadsChart, {
type: 'line',
data: downloadsChartData,
options: downloadsChartOptions
});
I tried to switch the data field to an array of values so that Chart.js would recognize the labels I defined in downloadsChartData to:
...
pointStyle: 'triangle',
data: [2, 0, 3, 1, 1]
}]
...
pointHoverRadius: 9,
data: [4, 2, 0, 1, 4]
}]
However, when I make this change, the chart not only doesn't correctly label the X axes, but also stops displaying the data on the line chart entirely.
Can someone please spot what I'm doing incorrectly? The documentation isn't too helpful in this matter.
The documentation is not very clear on this point, but for graphing non-numerical data (such as your case where the X axis represents a Date) you cannot set the X axis to have a linear scale. In other words, if you set your axis with a linear scale, it will graph the numerical representation of the data (and therefore, not the label).
I removed type: 'linear' from your downloadsChartOptions and it solved the issue.:
var downloadsChartOptions = {
title: {
display: true,
text: 'Downloads on Google Play and App Store',
fontSize: 30
},
scales: {
xAxes: [{
scaleLabel: {
display: true,
labelString: 'Date',
fontSize: 20
},
//type: 'linear',
position: 'bottom',
gridLines: {
display: false
}
}],
yAxes: [{
scaleLabel: {
display: true,
labelString: 'Downloads',
fontSize: 20
}
}]
}
};
I've started using the latest beta of v2 of chart.js since I need to draw a chart that contains both a stacked bar chart and an unstacked line chart on the same chart. Here's an example of what I need:
In this chart the lines are not stacked and are all showing their natural values but the bar chart is stacked and shows the combined total of the values (including some negative values).
I've managed to get the two charts drawn together but so far I've only succeeded in either having both charts stacked or I've had to use two separate y-axis which ends up with 2 scales. There's an example of the separate y-axis in this fiddle:
yAxes: [{
stacked: false,
ticks: {
beginAtZero: true
}
}, {
id: "bar-y-axis",
stacked: true,
ticks: {
beginAtZero: true
},
type: 'linear'
}]
If I remove the first y-axis then I ended up with a single scale with the only problem being that the line chart is now stacked as well.
Is there any way to draw a chart like I need using chart.js?
You can get this functionality with a combination of setting a different yAxisID (e.g. yAxisID: "bar-stacked") to each of your datasets, and then adding a second options.scales.yAxes object. So you would have this as a dataset:
{
label: 'Promoters',
backgroundColor: "#aad700",
yAxisID: "bar-stacked",
data: [
50, 44, 52, 62, 48, 58, 59, 50, 51, 52, 53, 54
]
}
and then you would add an additional yAxes (the first one will be the collection of your line datasets [no yAxisId in the example below], the second will be all of the bars you want stacked):
yAxes: [{
stacked: false,
ticks: {
beginAtZero: true,
min: 0,
max: 100
}
}, {
id: "bar-stacked",
stacked: true,
display: false, //optional if both yAxes use the same scale
ticks: {
beginAtZero: true,
min: 0,
max: 100
},
type: 'linear'
}]

Another answer here - you can set a 'stack' identifier for the data you want to be cumulative (i.e. just the bars), and turn off 'fill' on the line graphs to draw just as a line rather than mountain range
Chart.js remove stacking
You can set the stacked property on bar datasets, so lines don't stack.
Try something like this:
data: {
datasets: [{
label: 'Line 1',
data: [],
backgroundColor: '#3788d8cc',
borderColor: '#3788d8cc',
fill: false
}, {
label: 'Stacked bar 1',
data: [],
backgroundColor: '#e51c23',
borderColor: '#e51c23',
type: 'bar',
stack: 'bar-stacked'
}, {
label: 'Line 2',
data: [],
backgroundColor: '#ff9800',
borderColor: '#ff9800',
fill: false
},
{
label: 'Stacked bar 2',
data: [],
type: 'bar',
backgroundColor: '#3f51b5',
borderColor: '#3f51b5',
stack: 'bar-stacked'
}],
labels: [],
},
options: {
maintainAspectRatio: false,

scales: {
xAxes: [{
