JqPlot chart Chinese API user documentation and source code and online examples

Introduction

Jqplot is a very good jquery-based chart plug-in. This article mainly helps you sort out the Chinese usage instructions of jqplot and download online examples and source code. The jqplot plug-in displays charts on the canvas in HTML5-supported browsers.

Introduce script files

Jqplot must be supported by jquery version 1.4.3 or later. As mentioned earlier, jqplot will be presented as Canvas in browsers that support HTML5 canvas. Otherwise, if you are using a browser earlier than IE9, introduce excanvas. js files. Of course, jqplot CSS files should also be introduced at the same time. The Code is as follows:

Copy codeThe Code is as follows:
<! -- [If lt IE 9]> <script language = "javascript" type = "text/javascript" src = "excanvas. js"> </script> <! [Endif] -->
<Script language = "javascript" type = "text/javascript" src = "jquery. min. js"> </script>
<Script language = "javascript" type = "text/javascript" src = "jquery. jqplot. min. js"> </script>
<Link rel = "stylesheet" type = "text/css" href = "jquery.jqplot.css"/>


Add a plot container

We can add a container for jqplot on the page, such as div, but note that we need to specify the width and height for this div container, as shown in the following code:

<Div id = "chartdiv" style = "height: 400px; width: 300px;"> </div>

Start creating a plot chart

Next, we can call $. jqplot in the created container to generate and render the chart. For example, if the following data is used to initialize the jqplot chart:

$. Jqplot ('chartdiv ', [[1, 2], [3, 5.12], [5, 13.1], [7, 33.6], [9, 85.9], [1, 11,219.9]);

Shows the final display effect:

Jqplot attribute options
When calling $. jqplot, We can input some parameters options to customize jqplot. Some parameters options are as follows:
Copy codeThe Code is as follows:
