使用Aspose.Cells生成Excel的线型图表

目的：

1.根据模板里面的excel数据信息，动态创建line chart

2.linechart 的样式改为灰色

3.以流的形式写到客户端，不管客户端是否装excel，都可以导出到到客户端

4.使用Aspose.Cells的基本功能

5.使用mvc测试代码

导出到excel里面的效果图

使用Aspose.Cells 设置chart的y坐标轴显示值

目的：设置chart的y坐标轴显示值

用aspose.cell生成的chart生成的Y轴是默认生成的，自己要定义y轴坐标值
1.把数据源写到excel里面，list里面
2.y轴坐标自己定义

第一种：默认设置:chart里面会自己定义y轴坐标
第二种：y周坐标以对数显示 chart.ValueAxis.IsLogarithmic = true; 以10 100 1000格式显示
第三种：只设置间隔值 chart.ValueAxis.MajorUnit =20000;，会自动获取y轴的最大值与最小值
第四种：设置y轴的最大值与最小值，设置间隔值
//设置y坐标轴的厚度
chart.ValueAxis.AxisLine.Weight = WeightType.WideLine;
chart.ValueAxis.Title.Text = "y轴坐标";
chart.ValueAxis.MajorUnit =20000;//设置y轴的显示值间隔
chart.ValueAxis.MaxValue = 200000;//设置y轴开始最大值
chart.ValueAxis.MinValue = 0;//设置y轴的最小值

3.设置右边坐标轴是不是显示
//设置右边坐标轴显示
chart.SecondValueAxis.IsVisible = true;
//设置y坐标轴间隔值字大小
chart.SecondValueAxis.TickLabels.Font.Size = 12;
chart.SecondValueAxis.Title.Text = "y轴坐标2";

导出效果：

//设置y坐标轴的厚度
chart.ValueAxis.AxisLine.Weight = WeightType.WideLine;
chart.ValueAxis.Title.Text = "y轴坐标";
chart.ValueAxis.MajorUnit =20000;//设置y轴的显示值间隔
chart.ValueAxis.MaxValue = 200000;//设置y轴开始最大值
chart.ValueAxis.MinValue = 0;//设置y轴的最小值

第二种：y周坐标以对数显示 chart.ValueAxis.IsLogarithmic = true; 以10 100 1000格式显示

//设置y坐标轴的厚度
chart.ValueAxis.AxisLine.Weight = WeightType.WideLine;
chart.ValueAxis.Title.Text = "y轴坐标";
chart.ValueAxis.MajorUnit =20000;//设置y轴的显示值间隔
chart.ValueAxis.MaxValue = 80000;//设置y轴开始最大值
chart.ValueAxis.MinValue = 0;//设置y轴的最小值
