Jqplot is based on a basic jqplot. js files with multiple plug-ins supported by js files-that is, jqplot. js files can only be used to draw line charts. For pie charts and bar charts, pieRenderer must be introduced. js files.
Here, we will refer to the official jqPlot documentation and take the pie chart as an example to briefly describe the usage of jqPlot:
Step 1: Introduce the js file (if it is a chart other than a line chart, you need to introduce the relevant js file. Here, introduce the pie chart file pieRenderer)
Copy codeThe Code is as follows:
<! -- [If IE]> <script language = "javascript" type = "text/javascript" src = "./excanvas. js"> </script> <! [Endif] -->
<Link rel = "stylesheet" type = "text/css" href = "./jquery.jqplot.css"/>
<Script language = "javascript" type = "text/javascript" src = "./jquery-1.3.2.min.js"> </script>
<Script language = "javascript" type = "text/javascript" src = "./jquery. jqplot. js"> </script>
<Script language = "javascript" type = "text/javascript" src = "./plugins/jqplot. pieRenderer. js"> </script>

Step 2: Add a container for the chart display area
Copy codeThe Code is as follows:
<Div id = "chart" style = "margin-top: 20px; margin-left: 20px; width: 460px; height: 500px;"> </div>

Step 3: obtain data
Copy codeThe Code is as follows:
Line1 = [['frogs ', 3], ['buzzs', 7], ['deer', 2.5], ['turkeys', 6], ['moles ', 5], ['ground hogs ', 4];

Step 4: configure the Option object and create a chart
Copy codeThe Code is as follows:
$. Jqplot ('chart', [line1], {
Title: 'pierenderer', // set the title of the pie chart
SeriesDefaults: {fill: true,
ShowMarker: false,
Shadow: false,
Renderer: $. jqplot. PieRenderer,
RendererOptions :{
Diameter: undefined, // set the diameter of the pie
Padding: 20, // The distance between the pie and its category Name box or chart border, disguised as the diameter of the table pie
SliceMargin: 9, // distance between each part of the pie
Fill: true, // sets the status of each part of the pie.
Shadow: true, // sets a shadow for the border of each part of the pie to highlight its stereoscopic effect.
ShadowOffset: 2, // sets the distance between the border of each part of the pie to be removed from the shadow area.
ShadowDepth: 5, // sets the depth of the shadow area.
ShadowAlpha: 0.07 // sets the transparency of the shadow area.
}
},
Legend :{
Show: true, // set whether the category Name box appears (that is, the names of all categories appear in a certain position of the graph)
Location: 'ne ', // The position shown in the category Name box is nw, n, ne, e, se, s, sw, w.
Xoffset: 12, // The distance between the category Name box and the border on the chart area (unit: px)
Yoffset: 12, // The distance between the category Name box and the left border of the chart area (unit: px)
}
});

The complete code is as follows:
