Making responsive D3js charts is an essential part of creating data visualizations that are effective and accessible on the web. Data visualizations should respond to viewports exactly like every other element on the page, if not you could be failing a large number of your users. To execute code when the user resizes or changes the orientation of their browser we need an event listener. Event listeners are used for every kind of user interaction, some commonly used events are mouse and keyboard inputs.
To use an event listener you need three things; the DOM element you want to target, the type of event you want to listen for click, onmouseover, resize, etcand a function for what you want to happen when that event is triggered. Here's a super simple line chart made with D3. This isn't really a beginners guide to D3 but the code is straightforward:. What would happen if it was a larger chart being loaded on a phone?
We take the same approach to drawing it as before, but this time we need to wrap everything in a function that requires adjustments when the viewport is resized. Next we make our drawChart function I mentioned, in here we calculate and set everything we left out or the things that need to respond accordingly to the viewport.
When the page loads it will be the full viewport size, but when the user stretches their browser window nothing changes.
The last thing we need is window. So calling a function to do something when the browser resizes is pretty easy, but we need to think about the potential performance hit every time this chunk of code is executed.
When a user resizes their browser the resize event could be triggered hundreds of times, therefore executing our code hundreds of times. This is where we need a debounce. Debouncing is a method of controlling when a function is executed. It waits a set amount of time after the initial function call to see if that function gets called again, if it is called then it starts waiting again without executing the function.
This keeps the code from running an unnecessary amount of times. When I first learned about debouncing I thought it seemed like throttling, or setting a frequency limit on something, however it is much different. The demos at the bottom of the page are a good way to get a grasp on what is happening. At Able Sense we have a bunch of helper functions that we use in every project, one is a debounced onResize function. Here it is wrapped up nicely in a little module.
Calling it is simple:. It depends on the chart but something to consider could be an orientation change or a different layout at certain viewport break points, almost like CSS media queries. The chart needs to communicate the same data just in a different way depending on viewport size.

I'm trying out the example code for Chart. In my case, passing responsive: false under options solved the problem. I'm not sure why everybody is telling you to do the opposite, especially since true is the default. Not mentioned above but using max-width or max-height on the canvas element is also a possibility.

But when rendering the chart it's blown up to full page width, and cuts off the far right end. This is some bogus text because SO prohibits linking to Codepen otherwise. Fellow Stranger Fellow Stranger Active Oldest Votes. You can override the canvas style width! Evhz 5, 5 5 gold badges 31 31 silver badges 52 52 bronze badges.
Thank you, your maintainAspectRatio: false made the chart viewable. But still cutting off the right side though. Hitting these kind of issues already with their own basic example code makes me wonder wether chart. The right side is still cut off That solves the problem of graph size, the graph hasn't scaled to fit it. Is there a way to set the graph size from within Chart.
Turns out that you need to turn off responsive to make the graph obey the sizes given to it.

Shame that there doesn't seem to way to control it and maintain the responsive nature Thank you. Your maintainAspectRatio really helps for me. Nicolas Nicolas 4 4 silver badges 3 3 bronze badges. This works. The key here is to use an outer div and set the width and height on that rather than the canvas element. This should be the correct answer! In order for this to work, chart-container should be relatively positioned. Antimony Antimony Data is all around us. While search engines and other applications work most optimally with text based representation of data, people find data represented visually to be easy to comprehend.
This tutorial will provide a quick recap of that introduction followed by a deeper look into the features of Chart. The library supports six different chart types, each of these chart types coming with a load of customization options. If that is not enough, you also have the ability to create your own custom chart types. All six core chart types in Chart.
Below is the cdnjs link to include it:. In this section I will modify a few settings to demonstrate what Chart. For the first demonstration, I will create a line chart. There are some basic options that you need to set for the charts to make sense. The line chart expects an array of labels and datasets. The labels appear on the X axis. I have filled up the line chart with some dummy data.
The data is broken up into an array of data sets. Each data set has a color for the fill, the line, and the points. I have set fillColor to transparent in this case. Same goes for other values. I have included the code that sets some global values. There are many more options that you can modify according to your needs, such as scaleLineColor and scaleIntegersOnly. I suggest that you go through the Chart. Besides Global options, there are configuration options available for individual chart types.
I will set a few of these options in this line chart to give you an idea:. Charts generated by Chart. Setting responsive to true as done above makes them responsive. If you need to make every chart responsive, I recommend that you set this globally instead, like this:.

Bar Chart Below is the basic bar chart example.Your goal is to increase conversions and keep people engaged during checkout, and the best way to do this is with a clean design that encourages user activity. CodePen has tons of free open source shopping carts you can restyle for any purpose. Start Downloading Now!
Flat Cart. It works for all types of websites, and it helps designers focus more on the usability rather than aesthetics. The colors are easy to update and the interface features work the same regardless of layout style. Many checkout pages use tables to organize data but this example by Alex Rodrigues uses divs instead.
Each row holds enough data to restyle properly and to keep everything organized, even on super small screens. I like this responsive checkout a little more than others because the breakpoints feel more natural. This is great for a frontend cart page where the buyer may want to increase quantities before paying, and to see an estimate of the total costs.
Every so often new CodePen challenges pop up asking developers to create different interfaces like signup pages or modal windows. You can also click any product image to remove it from the cart with ease. These small features add a lot to the interface and make cloning a breeze. This UI is fantastic in all areas of code, design, usability, and the extra sprinkle of animation on top.
Tabbed widgets let you add content onto a single page and give users the power over that content. But the interface items are in place so a little jQuery magic would fix that.
Mixing the store and shopping cart into one interface is a tough job but Olivia Cheng got it done in this pen. Click this to add the item above with auto-updating prices. One unique feature is the quantity added on top of the item thumbnail.
This might get confusing on a real cart but if the numbers were a bit smaller this would be a great way to save space. Developer Bart Veneman created this clean shopping cart as a simple interface template. It auto-calculates the total price and even includes taxes near the checkout button.
The Web Designer Toolbox.When it comes to changing the chart size based on the window size, a major limitation is that the canvas render size canvas.
Furthermore, these sizes are independent from each other and thus the canvas render size does not adjust automatically based on the display size, making the rendering inaccurate. Detecting when the canvas size changes can not be done directly from the canvas element. However, this method requires the container to be relatively positioned and dedicated to the chart canvas only.
Responsiveness can then be achieved by setting relative values for the container size example :. Note that in order for the above code to correctly resize the chart height, the maintainAspectRatio option must also be set to false. CSS media queries allow changing styles when printing a page. The CSS applied from these media queries may cause charts to need to resize. However, the resize won't happen automatically. To support resizing charts when printing, one needs to hook the onbeforeprint event and manually trigger resizing of each chart.
Responsive Charts When it comes to changing the chart size based on the window size, a major limitation is that the canvas render size canvas. Configuration Options Name Type Default Description responsive boolean true Resizes the chart canvas when its container does important note Note that this option is ignored if the height is explicitly defined either as attribute or via the style. Gets passed two arguments: the chart instance and the new size. Important Note Detecting when the canvas size changes can not be done directly from the canvas element.
