基于CChart的K線繪制工具KLineChart-有解無憂

CChart是本人開發的一款C++曲線繪制庫，經過多年的迭代，目前已經發布了第四個大版本，見本人在論壇發布的帖子https://bbs.csdn.net/topics/392520079。
CChart的內核可拓展性非常好，最近在此基礎上，開發了一個繪制K線圖的工具KLineChart。
由于本人對股票一竅不通，這個工具還比較粗糙。
用此工具編制的一個界面如圖。

比較簡單，并不是非常專業的股票軟體界面，不過也還是可以用。如果有需求，后面還可以繼續完善。
下面簡單介紹一下這個工具的用法。
基于CChart的一貫特點，KLineChart的用法非常簡單，Attach到一個視窗上，然后加上K線資料即可。
這里是在一個最簡單的Win32程式里面示范。
首先準備資料，本人從網上拷貝了一個資料，如下所示。

{

	TCHAR strTime[32];

	double fOpen, fClose, fLowest, fHighest;

}KlData;

一個畫圖變數

static CKLineChartWnd chartWnd;

貼視窗

chartWnd.Attach(hWnd);

下面是真正需要的代碼



			for(i=0; i<sizeof(mydata)/sizeof(KlData); i++)

			{

				chartWnd.GetChart()->AddKNode(mydata[i].strTime, _T("%Y/%m/%d"), mydata[i].fOpen, mydata[i].fClose, mydata[i].fLowest, mydata[i].fHighest);

			}

			chartWnd.GetChart()->AddMALine(5);

			chartWnd.GetChart()->AddMALine(10);

			chartWnd.GetChart()->AddMALine(20);

			chartWnd.GetChart()->AddMALine(30);

			chartWnd.GetChart()->SetTitle(_T("滬市歷史日K圖"));

好了，大功告成！
上面的回圈是添加K線資料，后面用AddMALine函式添加了4條移動平均線，分別是5日，10日，20日，30日平均線。可以發現，代碼十分簡潔。
這段代碼的效果如上圖所示，不僅畫出了K線圖，還可以回應滑鼠動作。
