I want to use chart.js to plot the daily generation of my solar panels combined with the month total in one chart, much like in the image below. Both graphs alone are easy to produce, but all examples I find for a combined chart have the same amount of datapoints for both charts. I have 12 for the bar chart and 365 or 366 for the line chart.
Is it possible to make this?
Using timeseries as x-Axis, applying additional trick:
Try following:
set x-axis type to timeseries:
for each x-Axis scales: {'daily-x-axis': { type: 'timeseries' ...
for x-Axis type 'time' or 'timeseries' to work, you need additional libraries (like moment.js and its adapter)
Trick: for monthly totals in your data, use first day of month as x value, like x: "2021-01-01" etc ...
style your bars and labels/ticks, adding backgroundColor: 'rgba(0,0,255,0.5)', x- and y-Axis label colors, color of ticks, etc ...
let dailyGeneration = [{x: '2021-01-01', y: 1},{x: '2021-01-02', y: 3},{x: '2021-01-03', y: 2},{x: '2021-01-04', y: 5},{x: '2021-01-05', y: 8},{x: '2021-01-06', y: 2},{x: '2021-01-07', y: 11},{x: '2021-01-08', y: 10},{x: '2021-01-09', y: 7},{x: '2021-01-10', y: 6},{x: '2021-01-11', y: 1.5},{x: '2021-01-12', y: 3},{x: '2021-01-13', y: 4},{x: '2021-01-14', y: 6},{x: '2021-01-15', y: 0.5},{x: '2021-01-16', y: 3},{x: '2021-01-17', y: 9},{x: '2021-01-18', y: 8},{x: '2021-01-19', y: 7},{x: '2021-01-20', y: 6},{x: '2021-01-21', y: 6},{x: '2021-01-22', y: 4},{x: '2021-01-23', y: 3},{x: '2021-01-24', y: 1},{x: '2021-01-25', y: 1},{x: '2021-01-26', y: 2},{x: '2021-01-27', y: 5},{x: '2021-01-28', y: 8},{x: '2021-01-29', y: 7},{x: '2021-01-30', y: 12},{x: '2021-01-31', y: 2},

I have a chart that I have developed using Chart JS and it works good. The problem here is that when I hover on a point, the x axes of that point appears wrong! So for example in the image below, I am hovering on that orange point which have '23000' x axes point. but it appears '18428.91'! it has right values only with the first purple line on the bottom. I think the problem with the tooltip option but I do understand what’s the problem

After Editing:
Line charts default to a linear Y axis and a category X axis. Specifying data.labels explicitly sets labels for the x-axis category ticks but these are just text, and won't match the computed scale.
As x and y values are passed both axes need to be linear:
Remove the data.labels array.
Add the following to options:
scales: {
x: {
type: 'linear'
}
}

(function($) {

I have created a time series graph out of two data set. Now problem is there is an additional data that I would like to use and display in tooltip but I am not sure how to do it. I did some search and I kind of believe that this can be achieved via callbacks but don't know how to handle it. Right now the tooltip displays x and y values along with it I would like to display r value as well.

You'll have to create a custom tooltip and then append the r value to it.
You can read about tooltips over here
You can access a particular attribute of a tooltip's point like this:
data.datasets[tooltipItem.datasetIndex].data[tooltipItem.index].r
I wrote a custom callback to do this for you :)

I m trying to display an anual unemployment statistic on chart.js but I don't have the data for all the months. Is it possible to display all the data I have but keep all the labels( like for example I dont have data for july, I want the label 'july' to be written down there but no dot in the chart).
First, you should define the xAxis as a time cartesian axis. Then you define the data of your dataset as individual points through objects containing x and y properties.
Please note that Chart.js internally uses Moment.js for the functionality of the time axis. Therefore you should use the bundled version of Chart.js that includes Moment.js in a single file.
new Chart(document.getElementById("myChart"), {
type: "line",
data: {
datasets: [{
label: "Unemployments",
data: [
{ x: '2020-01', y: 50 },

You only have to add them together and make sure that your first created canvas is emptied whenever the second is created:
This is the JS you need:
var chart = new CanvasJS.Chart("chartContainer", {
title: {
text: "Using all form of color inputs",
fontColor: "#6A5ACD"
},
axisY: {
interlacedColor: "rgb(255,250,250)",
gridColor: "#FFBFD5"
},
data: [{
type: "column",
color: "darkgreen",
dataPoints: [
{
x: 10,
y: 71
}, {
x: 20,
y: 55
}, {
x: 30,
y: 50
}, {
x: 40,
y: 65
}, {
x: 50,
y: 95
}, {
x: 60,
y: 68
}, {
x: 70,
y: 28
}, {
x: 80,
y: 34
}, {
x: 90,
y: 14
}
]
}]
});
chart.render();
chart = {}; // empty your first chart
var chart1 = new CanvasJS.Chart("chartContainer1", {
title: {
text: "Using all form of color inputs",
fontColor: "#6A5ACD"
},
axisY: {
interlacedColor: "rgb(255,250,250)",
gridColor: "#FFBFD5"
},
data: [{
type: "column",
color: "darkgreen",
dataPoints: [
{
x: 10,
y: 71
}, {
x: 20,
y: 55
}, {
x: 30,
y: 50
}, {
x: 40,
y: 65

x: 70,

}]
});
chart1.render();
chart1 = {};
Look at this JSFIDDLE
Thanks everyone. I have exact solution with Google Chart.

Is there a way to add title to the axis? Typically, it is useful to have the y-axis display units. For example: http://code.shutterstock.com/rickshaw/examples/y_axis.html has just numbers, but in any kind of plot you would need to specify: %, $, km/s, etc. How to do that?
Thank you!
