VC6中调用 ProEssentials v5图表组件实现科学图表绘制(2)

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);
其他设定颜色和点类型的方法与以上方法类似，在此不再赘述。

3 实现结果：
绘制了一个图表，带游标和坐标显示功能，以下函数分别实现基本图表功能和游标显示功能。
void CPEView::CreateSimpleSGraph()
{
RECT rect;
GetClientRect( &rect )
m_hPE = PEcreate(PECONTROL_SGRAPH, WS_VISIBLE, &rect, m_hWnd, 1001);
if( m_hPE )
{
float fY;
float fX;
// 设置子集数和每个子集的点数 //
PEnset(m_hPE, PEP_nSUBSETS, 4);
PEnset(m_hPE, PEP_nPOINTS, 12);
for( int s=0; s<=3; s )
{ for( int p=0; p<=11; p )
{
fX = ((float) (p 1)) * 100.0F;
PEvsetcellEx (m_hPE, PEP_faXDATA, s, p, &fX);
fY = ((float) (p 1) * 1.0F) GetRandom(1, 250);
PEvsetcellEx (m_hPE, PEP_faYDATA, s, p, &fY);
