Var fourthSeries = chart.line(fourthSeriesData) create the fourth series with the mapped data Var thirdSeries = chart.line(thirdSeriesData) create the third series with the mapped data Var secondSeries = chart.line(secondSeriesData) create the second series with the mapped data Var firstSeries = chart.line(firstSeriesData) create the first series with the mapped data We then link each of those series to a different line and name each series based on the segments. To do that, we create a function that will return the data to keep it as a separate block of code. The data set for our line chart is pretty straightforward and not large at all. So we can simply include it inside the code itself. In this tutorial, we will be visualizing data from the GSS Data Explorer, namely the data that shows how the breakdown of responses to the question “Is it wrong for same-sex adults to have sexual relations?” changed over time between 19. Namely, we’ll represent the percentage of responses “Not wrong at all” that looks like a good indicator of acceptance here.Īn圜hart supports multiple options to load data to charts. All the code for the JS line chart will come here The JS line chart code itself will be written in the tag inside of the section. ![]() Since the line chart is one of the basic chart types, it requires only the base module of An圜hart. In addition, there are a lot of chart examples to check out and use as the starting point, as well as a utility called Playground to experiment with the code. It is a lightweight and flexible JavaScript (HTML5) charting library with detailed documentation and API reference. ![]() In this tutorial, the line chart is built with An圜hart. These scripts will go in the tag inside of the section. The second step is to reference all the necessary scripts to build the JS line chart. But it’s not necessary and can be customized according to your requirements, of course. Here, we provide the with the 100% width and height to render the line chart on the full screen. Width: 100% height: 100% margin: 0 padding: 0 To reference this block element later in the code, we give it an id attribute like “container”. To start, we create a basic HTML page with a block element for our line chart. So now, let’s dig into each of these steps to draw our line chart in a jiffy.
