ZedGraph教程.docx

1、ZedGraph教程ZedGraph 是一个非常优秀的开源的作图控件1、在 vs 中使用 ZedGraph2、基本一些概念几个注意点：图片的保存路径设置：RenderedImagePath 属性中设置，程序对该文件夹应该是有写和修改权限的图片的输出格式：OutputFormat 属性中设置，Png 的推荐，比较清晰。ChartChartBorder图表区域的边框设置ChartFill图表区域的背景填充Legend图表的注释标签显示设置项目，一组数据对应一种颜色的注释IsHStack当有多个显示项的时候设置 Y 轴数据是叠加的还是分开的Xaxis图表区域的 X 轴相关信息设置AxisColor坐

2、标轴颜色Cross坐标的原点，可以设置坐标的偏移程度CrossAuto原点自动设置：True 的话 Cross 的设置就无效了。FontSpecX 轴标题字体相关信息AngleX 轴标题字体显示时候的角度，0为水平 90为垂直FillX 轴标题字体填充信息ColorOpacity透明度IsScaled设置 X 轴标题字体显示大小是否根据图的比例放大缩小RangeMax填充时候的最大倾斜度（有过渡色，没试过）RangeMin填充时候的最小倾斜度（有过渡色，没试过）StringAlignmentX 轴标题字体排列（不清楚，没试过）IsOmitMag是否显示指数幂（10次方，没试过，似乎与 IsUs

3、eTenPower 有关系）IsPreventLabelOverlap坐标值显示是否允许重叠，如果False的话，控件会根据坐标值长度自动消除部分坐标值的显示状态IsShowTitleX 轴标题是否显示IsTicsBetweenLabels两个坐标值之间是否自动显示分隔标志IsUseTenPower是否使用10次幂指数IsZeroLine当数据为0时候是否显示（在饼状图显示的时候有用）IsVisible是否显示 X 轴MajorGrid大跨度的 X 轴表格虚线线显示信息DashOff虚线中孔间距DashOn虚线单位长度MajorTic大跨度的 X 轴刻度信息IsInside在 Chart 内部

4、是否显示IsOutSide在 Chart 外部是否显示IsOpposite在对面的轴上是否显示MinorGrid小跨度的 X 轴表格虚线显示信息MinorTic小跨度的 x 轴刻度信息MinSpace刻度和轴之间的距离（没试过）Scale刻度值的一些设定IsReverseX 轴的刻度值从高到低还是从低到高MajorStep大刻度步长MajorStepAuto是否自动设置大刻度步长MajorUnit大刻度步长单位Max刻度最大值MaxAuto根据输入数据自动设置刻度最大值Min刻度最小值MinAuto根据输入数据自动设置刻度最小值MinGrace不清楚，没试过MinorStep小刻度步长Mino

5、rStepAuto是否自动设置小刻度步长MinorUnit小刻度单位Type数据显示方式Liner直接现实（自动）Date按日期方式显示Log按指数幂方式显示Ordinal顺序显示Y2Axis第二个 Y 轴坐标信息显示（具体设置看 X 轴）Yaxis第一个 Y 轴坐标信息显示（具体设置看 X 轴）BarBase在生成柱状图的时候设置柱状是基于 X 轴还是其他轴BarType柱状的类型叠加或其他。IsFontsScaled图比例变化时候图表上的文字是否跟着自动缩放IsIgnoreInitial是否忽略初始值IsIgnoreMissing是否忽略缺省值IsPenWidthScaled图比例变化时候

6、图表上的画笔的粗细是否跟着自动缩放IsShowTitle图表标题是否显示PaneFillPane 的一些填充信息BaseDimension缩放比例基数（可以试试效果）IsImageMap不清楚干吗用的AxisChaneged是否允许自动绘图（没试过，一般都 true，动态绘图）CacheDurationCache 保存时间0OutputFormat输出格式RenderedImagePath输出路径RenderMode输出模式，不太清楚一般都是 ImageTag，另一个输出的是乱码不是图片。对于图表而言，一般是三种表现形式：柱状图、饼状图和点线图。ClassDescriptionMasterPa
