工控图表控件ProEssentials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);
