JavaScript开发中如何使用jQuery jqPlot插件绘制柱状图

　　在一个项目研发过程中，需要显示账户的资金情况，为了给客户良好的体验我们采用了柱状图形展现，绘图的过程如果使用原生态脚本绘制这样比较麻烦，时间也会比较长，所以我们选择了jqplot插件进行绘制，这样可以节省大量的时间，也能很快就能展示给用户。

　　插件官方地址：https://www.jqplot.com/

　　具体实现如下：

　　html代码

 

 

代码如下:

<p id="chart1" class="box"></p>

 

　　javascript脚本：

 

代码如下:

 var chartbar = function () {
         var data={param1:param1,param2:param2};//传递参数
         $("#chart1").html("");//绘图div
         var s1;
         $.ajax({
             type: "post",
             url: '../home/accountsum',
             data: data,
             datatype: "json",
             async: false,
             success: function (d) {
                 if (d.flag) {
                     s1 = [parsefloat(d.data.total1), parsefloat(d.data.total2), parsefloat(d.data.total3), parsefloat(d.data.total4), parsefloat(d.data.total5), parsefloat(d.data.total6)];
                 } else {
                     s1 = [0.00, 0.00, 0.00, 0.00, 0.00, 0.00];
                 }
                 $.jqplot.config.enableplugins = true;
                 var ticks = ['充值', '提款', '应收', '销售', '退票', '验证'];
                 var plot1 = $.jqplot('chart1', [s1], {
                     // only animate if we're not using excanvas (not in ie 7 or ie 8)..
                     //animate: !$.jqplot.use_excanvas,

                         }
                     },
                     axes: {
                         xaxis: {
                             show: true,    //是否自动显示坐标轴
                             renderer: $.jqplot.categoryaxisrenderer,
                             ticks: ticks,
                             showticks: true,        // 是否显示刻度线以及坐标轴上的刻度值 
                             showtickmarks: true,    //设置是否显示刻度

                                 showgridline: false // 是否在图表区域显示刻度值方向的网格
                             }
                         },
                         yaxis: {
                             show: true,
                             showticks: false,        // 是否显示刻度线以及坐标轴上的刻度值 
                             showtickmarks: false,     //设置是否显示刻度
                             autoscale: true,
                             borderwidth: 1,
                             tickoptions: {

                     grid: {
                         drawgridlines: true,
                         drawborder: false,
                         shadow: false,
                         bordercolor: '#000000',     // 设置图表的(最外侧)边框的颜色
                         borderwidth: 1           //设置图表的（最外侧）边框宽度 
                     },
                     highlighter: { show: false }
                 });
             },
             error: function () {
                 alert("获取图形统计数据失败!");
             }
         });

　　今天就写到这里吧，初步看了一下官方上的事例，功能还是蛮强大的，使用也很方便、容易，根据本项目的需求，后续可能还会增加一些。不过在使用过程中也发现了一些问题，部分实现不一定可以满足。
