緣起
同事負責的項目中，會掃描硬件中的某個東西是否存在，因此老板希望對這些掃描結果，能有個圖像畫的介面可以查看
因此做了個小工具，可讀取同事提供的數據，并將其視覺化顯示
那顯示掃描結果最容易的就是示波器了，但第三方控件的示波器功能又太繁瑣，最終就決定自己做個簡單的
反正對我來說用GDI來繪制，跟花時間去研究沒用過的第三方控件,時間也不會差太多

思路

復制代碼 代碼如下:

int max = m_mappingDatas[m_mappingDatas.Count - 1];
m_Ratio = (max + m_mappingDatas[0]*2) / m_width;
// Draw Wafer data
for (int i = 1, j = 0; i < m_mappingDatas.Count; i+=2 ,j++)
{
    float xStart = m_mappingDatas[i - 1];
    float xEnd = m_mappingDatas[i];
    graphics.DrawLine(pen, xStart / m_Ratio, m_yPositionOfWafer,
        xEnd / m_Ratio, m_yPositionOfWafer);
    graphics.DrawString((j+1).ToString(), Control.DefaultFont, brush,
        (xStart / m_Ratio) - 2, m_yPositionOfNoWafer + 1);
}
// Draw No Wafer data
graphics.DrawLine(pen, 0, m_yPositionOfNoWafer,
        m_mappingDatas[0] / m_Ratio, m_yPositionOfNoWafer);
for (int i = 2; i < m_mappingDatas.Count; i += 2)
{
    float xStart = m_mappingDatas[i - 1];
    float xEnd = m_mappingDatas[i];
    graphics.DrawLine(pen, xStart / m_Ratio, m_yPositionOfNoWafer,
        xEnd / m_Ratio, m_yPositionOfNoWafer);
}
graphics.DrawLine(pen, m_mappingDatas[m_mappingDatas.Count - 1] / m_Ratio, m_yPositionOfNoWafer,
        m_width, m_yPositionOfNoWafer);
// Draw vertical line
for (int i = 1; i < m_mappingDatas.Count; i += 2)
{
    float X1 = m_mappingDatas[i - 1];
    float X2 = m_mappingDatas[i];
    graphics.DrawLine(pen, X1 / m_Ratio, m_yPositionOfWafer,
        X1 / m_Ratio, m_yPositionOfNoWafer);
    graphics.DrawLine(pen, X2 / m_Ratio, m_yPositionOfWafer,
        X2 / m_Ratio, m_yPositionOfNoWafer);
}
