這篇文章將為大家詳細(xì)講解有關(guān)C#如何實(shí)現(xiàn)chart控件動(dòng)態(tài)曲線繪制，小編覺(jué)得挺實(shí)用的，因此分享給大家做個(gè)參考，希望大家閱讀完這篇文章后可以有所收獲。
具體內(nèi)容如下
實(shí)驗(yàn)室要做一個(gè)動(dòng)態(tài)曲線繪制，網(wǎng)上方法很多，但是缺乏完整代碼和效果圖的整合，往往總是缺少其一，因此整理如下，方便大家編程，節(jié)約時(shí)間。
思路：新建一個(gè)隊(duì)列，利用timer控件，動(dòng)態(tài)的往隊(duì)列中加入數(shù)據(jù)，每次觸發(fā)事件，就相當(dāng)于將隊(duì)列中的值全部重新畫(huà)一遍。
我的目的是做四個(gè)點(diǎn)的動(dòng)態(tài)監(jiān)測(cè)，所以代碼重復(fù)了四次，其實(shí)應(yīng)該用4個(gè)線程來(lái)做，思路就顯得較為清晰了，這也是可以改進(jìn)的地方。
