工控图表控件ProEssentials使用教程：创建蜡烛图

这些类型的图形实际上需要多个子集来定义绘制图形的不同方面。当构建一个这些类型的图表时,首先确保设置一个合适Subsets属性值。

将PlottingMethod设置为SpecificPlotMode，然后对SpecificPlotMode进行适当的设置。

例如,如果需要生成High-Low Bar(需要2子集)连同1条比较线用来显示每个条形图的中间点。

<span style="background-color:rgb(255,255,255)">Pego1.Subsets = 3
Pego1.Points = 4
 
Pego1.YData(0, 0) = 100: Pego1.YData(0, 1) = 150
Pego1.YData(0, 2) = 200: Pego1.YData(0, 3) = 250
Pego1.YData(1, 0) = 200: Pego1.YData(1, 1) = 250
Pego1.YData(1, 2) = 300: Pego1.YData(1, 3) = 350
Pego1.YData(2, 0) = 150: Pego1.YData(2, 1) = 200
Pego1.YData(2, 2) = 250: Pego1.YData(2, 3) = 300
 
Pego1.PlottingMethod = 15 ' 15 = Specific Plot Mode (for Graph)
Pego1.SpecificPlotMode = 1 ' 1 = High-Low Bar
 
Pego1.ComparisonSubsets = 1 ' One comparison subset
Pego1.PlottingMethodII = 8 ' Comparison Subset as Points + Line
 
Pego1.SubsetsToLegend(0) = -1 ' Get rid of subset legend area
</span>
