Front-end development practice: From 1920x1080 UI design draft to ECharts chart implementation

This article explains how to convert 1920x1080 pixel UI design drafts into actual code, especially developers who are familiar with backend system development and lack of experience in transcoding front-end design drafts and processing ECharts charts, and handles ECharts chart details in detail.

Challenge 1: Responsive layout of 1920x1080 design draft

Directly using fixed pixel values ​​in the design draft (such as width 200px and margin 40px) to layout will cause inconsistent display effects under different screen sizes. The solution is to adopt a responsive design and avoid using fixed pixel values.

It is recommended to use rem units or percentages for layout. The rem unit is based on the font size of the HTML root element, which facilitates the overall size of the page and realizes cross-device adaptation. For example, if the root element font size is set to 16px, then 1rem is equal to 16px. You can use JavaScript or CSS's calc() function to dynamically adjust the root font size to achieve scaled design drafts with the actual screen.

Challenge 2: Fine configuration of ECharts charts

When the UI design draft has strict spacing and size requirements for ECharts charts, configuration parameters are particularly important.

For ECharts newbies, it is recommended to refer to the official documentation or chart display website to find examples similar to the target chart type and style. On this basis, fine-tune the parameters according to the requirements of the UI design draft. Mainly concerned about the following aspects:

1. Chart size and margins: Adjust the overall size and margins of the chart through ECharts grid configuration items.
2. Chart element details: Adjust the chart element style and spacing through specific series configurations (such as bar , line , etc.).

Repeat preview and adjustments until the desired effect of the UI design draft is achieved.

Through the above methods, you can efficiently convert UI design drafts into front-end code and perfectly handle the details of ECharts charts, ultimately achieving high-quality front-end pages.
