前不久因为项目需要学习了NI MeasurementStudio里关于做图的控件!网上看了下,这方面的文章还真是少,所以现在我抛砖引玉写点我的应用心得!
现在开始:
首先呢肯定是要下载安装,我就懒的说了!
引用好了后,我就说一下
1.怎样给graph打格子,看看下图可能您就明白了.

2.画图代码如下:
PlotY(object yData);
ChartY(object yData);
PlotXvsY(object xData, object yData);
ChartXvsY(object xData, object yData);
3.一些代码:

#region 加载标识
        /// <summary>
        /// 添加通道
        /// </summary>
        /// <param name="color">颜色被定义为uint,并且以颜色的BGR(标准为RGB)的值排列 如:000000255为红色</param>
        /// <param name="xPostion1">通道线的x坐标</param>
        /// <param name="xPostion2">通道线的x坐标</param>
        private void AddChannelMaker(uint color, object xPostion1, object xPostion2, bool visible)
        {

            CWUIControlsLib.CWCursor Cursors1 = Graph.Cursors.Add();
            CWUIControlsLib.CWCursor Cursors2 = Graph.Cursors.Add();
