20. M a p X t r e m e 2 0 0 4 饼专题图（续） map.Layers.Add(thmLayer); // 修改专题图并重建，也可以在专题创建前设定 pieTheme.DataValueAtSize /= 2; pieTheme.GraduateSizeBy=GraduateSizeBy.Constant; thmLayer.RebuildTheme();

21. M a p X t r e m e 2 0 0 4 直方图专题 using MapInfo.Mapping; using MapInfo.Mapping.Thematics; map.Load(new MapTableLoader("world.tab")); FeatureLayer lyr = map.Layers["world"] as FeatureLayer; BarTheme barTheme = new BarTheme(map, lyr.Table, "Pop_Native","Pop_Male","Pop_Female"); ObjectThemeLayer thmLayer = new ObjectThemeLayer("Pop Male / Female", null,barTheme); map.Layers.Add(barTheme); barTheme.Stacked = true; barTheme.GraduateSizeBy = GraduateSizeBy.Constant; thmLayer.RebuildTheme();

22. M a p X t r e m e 2 0 0 4 范围标注地图 LabelLayer ll = map1.Layers.item(5); LabelSource labelSource = ll.sources(0); // 基于标注图层的 labelsource 创建 RangedLabelTheme rangedLabelTheme = new RangedLabelTheme(labelSource.Table, columnName, themeAlias, 5,DistributionMethod.EqualCountPerRange); // 将标注样式修改增加到标注图层 LabelModifier labelModifier = rangedLabelTheme as LabelModifier; labelSource.Modifiers.Insert(0, labelModifier);

23. M a p X t r e m e 2 0 0 4 独立值标注专题图 // 创建新的独立值标注专题 IndividualValueLabelTheme theme = new IndividualValueLabelTheme(labelSource.Table, columnName,themeAlias); // 为标注增加标注修改样式 LabelModifier labelModifier = theme as LabelModifier; labelSource.Modifiers.Insert(0, labelModifier);

24. M a p X t r e m e 2 0 0 4 点密度专题图 using MapInfo.Mapping; using MapInfo.Mapping.Thematics; // 加载表 map.Load(new MapTableLoader("World.tab")); // 在图层上加入样式修改作为点密度专题图 DotDensityTheme thm = new DotDensityTheme(lyr, "Pop_1994", "World Pop", System.Drawing.Color.Red, DotDensitySize.Large); FeatureLayer lyr = map.Layers["World"] as FeatureLayer; lyr.Modifiers.Append(thm);

26. M a p X t r e m e 2 0 0 4 示例 – 创建专题图例 using MapInfo.Data; using MapInfo.Mapping; using Mapinfo.Mapping.Thematics; Map map = mapControl1.Map; Table table = MapInfo.Engine.Session.Current.Catalog.OpenTable("world.tab "); FeatureLayer layer = new FeatureLayer(table); map.Layers.Add(layer); BarTheme theme = new BarTheme(map,layer.Table,"Pop_0_14","Pop_15_64","Pop_65 Plus"); ObjectThemeLayer themeLayer = new ObjectThemeLayer ("World Pop", null, theme); map.Layers.Add(themeLayer);

27. M a p X t r e m e 2 0 0 4 示例 – 创建专题图例（续） // 创建图例 legend = map.Legends.CreateLegend(new Size(5, 5)); legend.Border = true; ThemeLegendFrame frame = LegendFrameFactory.CreateThemeLegendFrame("Are a", "Area", theme); legend.Frames.Append(frame); frame.Title = "Area (sq. mi.)"; map.Adornments.Append(legend); // 设置起始坐标 System.Drawing.Point pt = new System.Drawing.Point(0, 0); pt.X = mapControl1.Size.Width - legend.Size.Width; pt.Y = mapControl1.Size.Height - legend.Size.Height; legend.Location = pt;}

28. M a p X t r e m e 2 0 0 4 示例 – 创建图形图例 using MapInfo.Mapping; using MapInfo.Mapping.Thematics; // 创建图例 System.Drawing.Size size = new System.Drawing.Size(400, 400); legendFactory = session.LegendFactory; legend = legendFactory.CreateLegend(map, size); frameFactory = legend.LegendFrameFactory; // 为图例家图框 frame = frameFactory.CreateCartographicLegendFrame(lyr, "State", "State", RowTextSourceType.Expression); legend.Frames.Append(frame);
