![]() ![]() D3 CHART RESPONSIVE RESIZE HOW TOMost d3 users who are concerned with responsive visualizations will already know how to build their update events into functions that are easy to call as shown in the intro topic and this topic. Another common problem with responsive charts and D3 is that once the screen gets smaller, the labels of the x-axis could overlap. The resize function will need to make a call to your main update function that will redraw all paths, axis, and shapes just as if the underlying data had been updated. ![]() This is an extremely simplified example, but does cover the basic concepts of how to setup charts to be responsive. You can make the responsive by adding a preserveAspectRatio attribute of xMinYMin meet, and a viewbox attribute of 0 0 WIDTH HEIGHT. As long as the is responsive, the content you add with D3 will scale automatically. Call our resize function if the window size is changed. append('svg') The is the element you need to make responsive.Width = document.getElementById('chartArea').clientWidth We will build a basic function to handle window resizing. Var svg = d3.select('#chartArea').append('svg') I like to use the golden rectangle ratio if they work for my charts. attr('viewBox', '0 0 ' + width + ' ' + height). this allows us to collect the width of the div where the SVG will go. In the matrix chart I mentioned earlier, the SVG settings are like below: var svg d3.select(lector).append('svg'). chart.js var width = document.getElementById('chartArea').clientWidth D3 CHART RESPONSIVE RESIZE FULLThis will create a colum that will be full screen on mobile device and half on a large screen. Let's first create a row and a column that our chart will be built in. Using this in conjunction with clientWidth variable and the window.onresize event, it is very easy to create responsive d3 SVGs. One approach that is employed often is to use bootstrap's gridded framework in order to define the area that the chart will exist in. Weâll also examine a reusable function that can be used to make nearly any visualization responsive. This lesson introduces the viewBox attribute, which is used to control how SVGs scale. var width = document.getElementById('chartArea').clientWidth Making SVGs responsive is unfortunately not as simple as adding some media queries. ![]()
