X轴: xAxis: { categories: ['周一', '周二', '周三', '周四', '周五', '周六', '周日' ], //X轴的坐标值 title: {text: '周数'}, //X轴坐标标题 } Y轴: yAxis: { title: {text: '人数(人)'}, //Y轴坐标标题 } 主标题: title: { text: '图表主标题' }, //
X轴:
xAxis: {
categories: ['周一', '周二', '周三', '周四', '周五', '周六', '周日' ], //X轴的坐标值
title: {text: '周数'}, //X轴坐标标题
}
Y轴:
yAxis: {
title: {text: '人数(人)'}, //Y轴坐标标题
}
主标题:
title: { text: '图表主标题' }, //图表主标题
副标题:
subtitle: {text: '图表子标题' }, //图表副标题
Y轴数据:
series:[{ name: '人数', data: [20, 40, 30, 90, 100, 60, 50] }]
这些值我们都可以从数据库获得数据,然后动态绑定上去即可,这里后台代码中最常用的是StringBuilder,通过它来拼凑出要绑定的数据
X轴:
xAxis: {
categories:
, //X轴的坐标值
title:
, //X轴坐标标题
}
Y轴:
yAxis: {
title:
, //Y轴坐标标题
}
主标题:
title: , //图表主标题
副标题:
subtitle: , //图表副标题
Y轴数据:
series:
下面给出获取X轴、Y轴、标题的方法:
public string XAxisCategories = ""; //X轴
public StringBuilder seriesData = new StringBuilder(); //Y轴
public string title = ""; // 图表标题
...
标题获取
title = "{text: '" + ""+site_name +""+"'}"; //红色标记的部分是从数据库动态获取的,怎么获取,该获取什么,根据你需要,你应该懂的
X轴获取:
StringBuilder xAxisCategories = new StringBuilder();
xAxisCategories.Append("[");
...
foreach (DataRowView drv in ds.Tables[0].DefaultView)
{
xAxisCategories.Append("'");
xAxisCategories.Append(drv["周数"] == null ? "0" : drv["周数"].ToString());
xAxisCategories.Append("',");
}
XAxisCategories = xAxisCategories.Replace(",", "", xAxisCategories.Length - 1, 1).Append("]").ToString(); //这里是去掉最后一个多余的逗号(,)
Y轴获取:
StringBuilder yAxisCategories = new StringBuilder();
...
foreach (DataRowView drv in ds.Tables[0].DefaultView)
{
yAxisCategories.Append(drv["人数"] == null ? "0" : drv["人数"].ToString());
yAxisCategories.Append(",");
}
seriesData.Append("[{name: '人数',type: 'spline',data: [");
seriesData.Append(yAxisCategories.Replace(",", "", yAxisCategories.Length - 1, 1)); //去除最后一个逗号(,)
seriesData.Append("]}]");
