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：

绘制了一个科学图表，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); } }

// 设置阴影
