工控图表控件ProEssentials使用技巧——如何改变子集的颜色和线条风格

在Proessentials控件中，可以按照用户的喜好自定义图表子集的颜色和线条以及点的风格。

颜色是由SubsetColors属性控制的。

线条风格是由SubsetLineTypes属性控制的。

点风格是由SubsetPointTypes属性控制的。

第一个指数(0)对应于第一子集,第二个指数(1)对应于第二子集,以此类推。

示例代码如下：

'//The following VB.NET example sets colors for three subsets //  Pego1.PeColor.SubsetColors(0) = Color.FromArgb(255,255,0,0)'(0) sets first subset  Pego1.PeColor.SubsetColors(1) = Color.FromArgb(255,0,255,0)'(1) sets second subset  Pego1.PeColor.SubsetColors(2) = Color.FromArgb(255,0,0,255)'(2) sets third subset  {The following Delphi example sets line styles for three subsets:}

Graph.SubsetLineTypes[0] := PELT_THINSOLID;{[0]index sets first subset}

Graph.SubsetLineTypes[1] := PELT_DASH; {[1]index sets second subset}

Graph.SubsetLineTypes[2] := PELT_DOT; {[2]index sets third subset} //The following C/C++ example sets line styles for three subsets: int nTmpStyles[3];

nTmpStyles[0] = PELT_THINSOLID;

nTmpStyles[1] = PELT_DASH;

nTmpStyles[2] = PELT_DOT;

PEvset(hPE, PEP_naSUBSETLINETYPES, nTmpStyles, 3); //Note that this C example uses PEvset. It could have also used PEvsetcell like... int nTmpStyle;

nTmpStyle = PELT_THINSOLID;

PEvsetcell(hPE, PEP_naSUBSETLINETYPES, 0, &nTmpStyle);

nTmpStyle = PELT_DASH;

PEvsetcell(hPE, PEP_naSUBSETLINETYPES, 1, &nTmpStyle);

nTmpStyle = PELT_DOT;

PEvsetcell(hPE, PEP_naSUBSETLINETYPES, 2, &nTmpStyle);
