C#繪制實(shí)時(shí)曲線圖-創(chuàng)新互聯(lián)

今天下午在終端機(jī)器上的曲線顯示本打算用控件，可控件折騰好長時(shí)間也沒弄順，還是自己寫的好使，記錄下來后面再改進(jìn)。
//繪圖部分的定義
Int32 Draw_Top;//繪畫Y起點(diǎn)
Int32 Draw_Left;//繪畫X起點(diǎn)
Int32 Draw_EdgeWidth;//X邊緣寬度
Int32 Draw_EdgeHeight;//Y邊緣高度
Int32 Draw_RangeWidth;//繪畫范圍寬度
Int32 Draw_RangeHeight;//繪畫范圍高度
Double[] XTDYData = new Double[21];
Int32 ICountDraw=0;

在數(shù)據(jù)接收的事件中進(jìn)行曲線繪制：
//顯示趨勢圖
ICountDraw = ICountDraw + 1;
if (ICountDraw ==21)
{
for (int i=1;i<21;i++)
{
XTDYData[i - 1] = XTDYData[i];
}
XTDYData[20]= YBDWDealWithData.TYNDianYa.dValue;
ICountDraw = 20;
}
else
{
XTDYData[ICountDraw] = YBDWDealWithData.TYNDianYa.dValue;
}
FuncDrawYBDW();

g.DrawImage(bmp, new Point(0, 0));//在內(nèi)存中畫完后顯示在pictureBox1上，避免閃爍
