Getting Started
The first step is to assemble all of your data. Once you have the data ready, you will need to create a div with an id-attribute: “myTotalChart”. This will make it easier to identify the chart when you’re coding the HTML.
The second step is to convert the data into a format that the HTML can use. The best way to do this is to make sure that each data point is structured as a number or data label (the labels can be anything you want).
Creating the HTML
Once you have the data ready, you will need to map out the HTML chart. This is done by creating an unordered list of the data points. A few lines of HTML will look something like this:
- Data 1
- Data 2
- Data 3
- Data 4
Once you have the data points mapped out, you will need to add in the styling for your chart. First, you need to set up the chart size and position. You can do this by using CSS classes and the “position:absolute;” command.
Once you have your sizing and positioning taken care of, you will need to set up the axes and the chart fill. For the axis settings, you can use the “vertical-align” and “text-align” commands. You will also need to use classes for the chart fill; for example, “data-fill-1”, “data-fill-2”, etc.
To get the chart to render properly, you will need to set the “display” CSS property to “block”. Finally, you will need to add the JavaScript code to generate the chart. This is done by adding a “script” tag in the head section of the HTML document.
Generating the Chart
The JavaScript code you add is going to create the histogram. You will need to create an array of numbers that correspond to the data points in the HTML and then map them to the chart.
You can do this by looping through the array and creating the “horizontal” and “vertical” axes of the chart. You can then use the “fill” classes you created earlier to generate the chart.
Once the chart is created, you can use the “addEventListener” command to make the chart interactive. This will allow the user to hover over the chart and view the data points in a tooltip. You can also use this command to change the chart when the user clicks on data points or changes the axes.
Finishing Up
When the chart is rendered, you will only need to make a few small adjustments. This includes: changing the chart title, adding a legend and a few other formatting elements. Once you have done this, you will have a beautiful histogram ready to show to the world!
Conclusion
Creating an histogram with HTML doesn’t have to be hard. With the right know-how and a bit of practice, you can have a beautiful, interactive chart in no time. So gather up your data, map it out in HTML, add some styling, then hit the JavaScript code to render the chart. And before you know it, you’ll have a stunning histogram ready to be shared!
