我使用pictureBox1來畫波形,可是在設定上有參考指另設定跟看過書,卻還是有些問題跟不對,不知到哪裡出現錯
((g - 1) * pictureBox1.W / length)=x1 (-na1 / 1 + pictureBox1.Height + pictureBox1.Height / 150)=y1
(g * pictureBox1.Width / length)=x2 (-na2 / 1 + pictureBox1.Height + pictureBox1.Height / 150))=y2
以下是我設定的方式:
int g;
int length = 500; >>>設定長度為500
if (g >= length)
{
pictureBox1.BackColor = Color.White; >>想將piatureBox1畫面清乾淨
g = 0;
}
else if (g < length)
g = g + 1;
if (InputData > 0)
{
int na, na1, na2;
int nb, nb1, nb2;
Graphics pictureBox1 = this.CreateGraphics(); >>設定畫布
pictureBox1.DrawLine(Pens.Red, ((g - 1) * pictureBox1.Width / length), (-na1 / 1 + pictureBox1.Height + pictureBox1.Height / 150), (g * pictureBox1.Width / length), (-na2 / 1 + pictureBox1.Width+
pictureBox1.Height / 150));
>>設定以做標形式來畫波形,可是這邊pictureBox1的Width和Width都會顯示未宣告,我的想法是想要將波形控制在pictureBox裡面,但是寬跟高在C#裡面要例外設定嗎?
