Introduction to simple Plotting Program Development in RequireJS The emergence of RequireJS makes it easy to modularize the front-end code. When the front-end project grows and the code grows, the modular code makes the project structure clearer, not only makes our ideas clearer during development, in addition, it is easier to maintain it later. The following is a simple plotting program developed by using

It must be noted that, because it is unable to ensure that all browsers used by users support the canvas Element, "Fallback content" must be added to the Development of canvas-based Web applications ", to remind users that they cannot normally experience this function, or suggest them download the latest browser.Here, curious readers may ask, since this is a common DOM node, it means that the canvas size can be changed

Draw line segments for HTML5 canvas basic plotting It is a new label added in HTML5 for drawing graphics. In fact, this label is the same as other labels. Its special feature is that this label can obtain a CanvasRenderingContext2D object, we can use JavaScript scripts to control this object for plotting. It is just a container for drawing graphics. In addition to attributes such as id, class, and style, th
