I am trying to plot some heavy data on zing Chart. Zing charts are normally plot inside a div but for my case my page became leggy after loading 200k points inside zing chart div-tag. In the doc it says to load large data in Canvas.
In the performance documentation of zing chart; in the end of document there is Render type, it says to load in canvas but its not working. according to doc
Render Type
The render method is where you can define the output, which can either render Canvas or SVG. If you are rendering a large dataset, the performance of Canvas will benefit you because DOM explosion happens when rendering in SVG.
Here is my code any suggestion or help.
function chart_timeFreq_ff_fh(timeArray, frequency_array_ff, frequency_array_fh) {
zingchart.DEV.SORTTOKENS = 0;
zingchart.DEV.PLOTSTATS = 0;
zingchart.DEV.RESOURCES = 0;
zingchart.DEV.KEEPSOURCE = 0;
zingchart.DEV.COPYDATA = 0;
zingchart.DEV.MEDIARULES = 0;
zingchart.SYNTAX = 'dashed';

Updated
I have tried to plot like this but still issue. Above chart is also updated and we i need to change how I pass time ? my time format is like 2022-10-10 23:24:03 an array of time like this so in the 'scale-x': { labels: timeArray} i add time like this
"series": [
{
values: [],
'line-color': "#3366ff",
'background-color': "#3366ff",
text: "Centeral Frequency"
},
{
values: [],
'line-color': "#00cc99",
'background-color': "#00cc99",
text: "Frequency Hopping"
}
]
configTimeAndAngle.series[0].values.push([frequency_array_ff]);
configTimeAndAngle.series[1].values.push([frequency_array_fh]);
configTimeAndAngle.series[0]=values.[frequency_array_ff];
configTimeAndAngle.series[1]=values[frequency_array_fh];
configTimeAndAngle.series[0]=frequency_array_ff;
configTimeAndAngle.series[1]=frequency_array_fh];
I've managed to create you a demo in a studio application with over 200k nodes, maybe you can use this setup with canvas in the render method for reference and see how it goes. I hope this helps.
To be honest I also had the same issue all day, then I saw this and I have found the issue on your question. you have use canvas instead use div and while rendering use
// this is your code
$('#canvas_div_f').append(
'<canvas id="lineChart_f" style="min-height: 400px; height: 550px; max-height: 500px; max-width: 100%;"></canvas>'
);
instead just use
$('#canvas_div_f').append(
'<div id="lineChart_f" style="min-height: 400px; height: 550px; max-height: 500px; max-width: 100%;"></div>'
);
and while render set output to canvas.
zingchart.render({
id: 'lineChart_cob_f',
data: configTimeAndAngle,
height: "100%",
width: "100%",
output: "canvas"
});

Is there a way to make the div wrapping the chart part of the fullscreen as well?
This is my code: fiddle
THis code only fulscreens the chart. When I try and do to point the div I need in the fullscreen:
Highcharts.FullScreen = function(container) {
this.init(ontainer.parentNode.parentNode);
};
My fullscreen is getting cut off and also not adding the parent div to the full screen. Is there to make the whole div with id yo and the other div inside (<div>Random Data and text.......</div>) as part of the fullscreen?
You can connect the content of a custom element through chart.renderer.text().add() by specifying this element with the html() method:
chart.renderer.text(selector.html(), 0, 0).add();
...hiding this element through css, set the display: none:
.random_data {
display: none;
}
This is the piece of code to add:
function (chart) {
chart.renderer
.text($(".random_data").html(), 10, 10)
.css({
color: "green",
fontSize: "12px",
})
.add();
}

let chart = Highcharts.chart(
"container",

})
.add();
}
);
let btn = document.getElementById("btn");
btn.addEventListener("click", function () {
Highcharts.FullScreen = function (container) {
console.log(container.parentNode.parentNode);
this.init(container.parentNode); // main div of the chart
};
Highcharts.FullScreen.prototype = {
init: function (container) {

container.requestFullscreen();
} else if (container.mozRequestFullScreen) {

So I've got a pretty small div, in which I gotta get a small timeline chart shoved in. The current problem is, that due to the chart being perfectly centered, I have a lot of whitespace I could really use, to make the actual data and chart much larger.:
I think showing the parent div shouldn't matter(because changing around these sizes doesn't really affect the chart itself). It feels like there's some option in the configuration that I'm missing. I've tried setting offsetY and even offsetX to negative values, because I was desperate, but to no avail.
<html>
<div id="chartTarget" style="height: 100; width: 100%;">
<canvas id="chartCanvas" height="100"></canvas>
<div style="opacity:0;" class="chartTooltip center">
</div>
</div>
</html>
Relevant code is pretty much straight up copied from the example, but since I'm bound to get questions about it, here goes:

var chart = new ApexCharts(document.querySelector("#chartTarget"), options);
chart.render();
I need the label, so things like sparkline aren't useful.
A negative offset at the chart level seems to have fixed for my needs.
chart.offsetY: -25
I assume everyone else can play with negative offset values, where available for more fine tuning.
I'm creating gauge charts using c3.js. I'm setting the height and width both to 75 because that's the right size of the gauge that I'm wanting, however when they get generated, there's always extra whitespace in the container that's messing me up.
I really want the svg that gets created to have a height of 60 in order to move the label up properly. The problem, is that when I set the height/width of the chart to 60, the size of the gauge itself gets way too small because of this extra whitespace.
I've tried setting the padding of everything that I know of to 0. I've searched through the documentation, there's always a chance that I've overlooked something. I can always try to do some hacky css to get around it, but before I do that, I'd like to change something in the configuration if I can.
Essentially, I want the chart to take up the full size that I specify. It seems that the legend, that I've specified to not show, is still taking up space that the chart should use.
http://jsfiddle.net/kLsox4ya/1/
<div class='row'>
<div class="col-12" id="chart"></div>
<p class="col-12 f-small">PERFECT</p>
</div>
var chart = c3.generate({
bindto: '#chart',
data: {
columns: [['data', 0]],
type: 'gauge'
},
gauge: {
fullCircle: true,
startingAngle: 2 * Math.PI,
width: 3,
expand: false,
label: {
show: false
}
},
size: {
height: 75,
width: 75
},
legend: {
show: false
},
interaction: {
enabled: false
}
});
You are going to have a hard time getting that much control over c3. It's doing a lot under the hood to calculate positions for axis, legends, etc... that you aren't even using.
I think you have two options:
Code it yourself using straight d3
Resort to a little hackery. For instance here, I've manually adjust the height after it renders.
var chart = c3.generate({
bindto: '#chart',
data: {
columns: [['data', 90]],
type: 'gauge'
},
tooltip: {
show: false
},

pattern: ['#565656', '#cfd628', '#e8b532', '#28d632'],

}
},
gauge: {
fullCircle: true,
startingAngle: 2 * Math.PI,
width: 3,

format: function (value, ratio) {
return '';
},
extents: function (value) {
return '';
}
}
},

},
legend: {
show: false
},

},

x: {

},
y: {
show: false
}
},
padding: {
top: 0,

bottom: 0,

},
onrendered: function(){
this.svg.attr('height', 55);
}
});

I've always use flot.js for common charting requirements, but I'd like to explore new ways to visualize data that might be beyond this charting library. I'd appreciate any advice or recommendations as to how others might programmatically render the custom display chart below. Maybe CSS?
I know you probably weren't looking for an answer spelling out how to implement this in flot, but it was a fun exercise.
Getting creative with hiding and stacking bars with the stack plugin allows you to represent your bounds. For each set of bounds, you'll need to create a hidden bar with your lower bound value and then create a visible bar with your upper bound value (and stack the two). Specifying which bars should stack on each other is easy by setting the stack option to the same key.
Once the bars are setup, the next step is to set the options of the chart. A grid marking handles displaying the current value. Hiding both axes effectively hides the grid.
The rest comes down to creating methods to append div elements to placeholder to show the bar values, labels, and marking value.
This is a basic implementation of your example image that really focuses on the flot component of the chart. With a bit more time, the extra appended div elements could be styled in such a way to more closely match your example.
This JSFiddle contains the code below for easier review.

I have used Fusion Charts. Its pretty easy to customize and it works well in all browsers. Also have a look at Chart JS. Its pretty cool and its open source
I'v been using Chart.js for a while. While it is sweet at first glance, and you really can do super awesome stuff with it out of the box, it can be really limiting later on when you come across the need to do some simple/custom details that are not in documentation. For example: label outside the chart; turning off background for bar chart, doughnut bar with 1 value (for example - i have doughnut chart, with value 20%, i want the difference to be colored - you cant do that).
Of course all these stuff can be addressed and made with customizing .js file, and extending it but if you don't have time for that and you want out of the box solution, you can be stuck on simple detail so i suggest reading full docs to see if it is up to your expetations.
I would recommend D3.js with the caveat the the learning curve is steep; let me try to explain:
In something like chart.js, chartist,etc you provide the data, chart type and some configuration and you have your chart. In D3, it is a bit more complicated in the sense that D3 provides the framework for displaying and interacting with data via the Dom elements you design and specify.( Mostly svg's although you can also use divs,spans etc)
While it feels daunting at first and the documentation is basically an API Reference, there are hundreds of examples you can use as base or inspiration.
I'v been using (ChartJS, Morris, Inline Charts) for dashboard. It may help you much to customize the chart
I would recommend Chartist.js. It is fully responsive with great flexibility and DPI dependent.
you're able to style your charts with CSS in #media queries and lot of animation options. they have given examples for line chart, bar chart, pie chart with code. So it will definitely help you.
I like amCharts.
Can do all kinds of stuff and is free to use.
Google gives you an interesting charting library.
May want to try that but it requires you to be connected to Google for it to work (can't run it offline).
Here's a shot at it with HighCharts. I adapted the 'Stacked and grouped column' example at http://www.highcharts.com/demo/column-stacked-and-grouped.
Obviously there's work to be done in getting the labels and axes right, but I think this is a good start.

I've been asked to do this kind of graph (40,9% and 16,4% are examples, they should indicate something like -6% and 9%):
Any idea on how I can get that kind of result, using a javascript library, if possible (but it is not a must) Highcharts?
Thanks
It's possible with HighCharts, Documentation
e.g.
$(function () {
data = [{
valSecond: 25,
valFirst: 62.5
}];
// Build the data arrays
var secondData = [];
var firstData = [];
for (var i = 0; i < data.length; i++) {
// add second data
secondData.push({
name: "Second",
y: data[i].valSecond,
color: "#00FF00"
});
// add first data
firstData.push({
name: "First",
y: data[i].valFirst,
color:'#FF0000'
});
}
// Create the chart
$('#container').highcharts({
chart: {
type: 'pie'
},
title: {
text: ''
},
plotOptions: {
pie: {
animation: false,
shadow: false,
