<font =“apple-style-span”=“” face=“arial, helvetica, sans-serif” size=“2”>最近開始接觸Labview…想請問一下…

<font =“apple-style-span”=“” face=“arial, helvetica, sans-serif” size=“2”><span =“apple-style-span”=“” style=“line-height: normal; “>我已經能從txt檔的數據中在waveform Graph中劃出波形，並能有十字能準確抓取XY值…
<font =“apple-style-span”=”” size=“2”><font =“apple-style-span”=“” face=“arial, helvetica, sans-serif”><span =“apple-style-span”=“” style=“line-height: normal;”>想說能不能在<span =“apple-style-span”=“” style=“font-family: arial, helvetica, sans-serif; line-height: normal; “>waveform Graph中滑鼠點擊波形上的值，然後依照值去抓取TXT檔內的數據?!
<font =“apple-style-span”=”” face=“arial, helvetica, sans-serif” size=“2”><span =“apple-style-span”=“” style=“line-height: normal;”>
<font =“apple-style-span”=“” face=“arial, helvetica, sans-serif” size=“2”><span =“apple-style-span”=“” style=“line-height: normal;”>X軸為第幾筆。Y軸為波形數據。
<font =“apple-style-span”=“” face=“arial, helvetica, sans-serif” size=“2”><span =“apple-style-span”=“” style=“line-height: normal;”>
<font =“apple-style-span”=“” face=“arial, helvetica, sans-serif” size=“2”><span =“apple-style-span”=“” style=“line-height: normal;”>想說能點擊的話要"在點擊的XY值計算出前一百筆總和的平均"…
<font =“apple-style-span”=“” face=“arial, helvetica, sans-serif” size=“2”><span =“apple-style-span”=“” style=“line-height: normal;”>
<font =“apple-style-span”=“” face=“arial, helvetica, sans-serif” size=“2”><span =“apple-style-span”=“” style=“line-height: normal;”>不曉得能不能這樣?!
<font =“apple-style-span”=“” size=“2”>煩請前輩指點一下…有搜尋過了。還是有哪些關鍵字可以參考…

txt檔的數據都在waveform Graph中,也知道<span style=“line-height: normal” =“apple-style-span”>X軸表示第幾筆,直接在waveform Graph中抓取數據就好了,為何要再去抓取TXT檔內的數據???

<font =“apple-style-span” size=“2”>抱歉，可能沒表示清楚。

<font =“apple-style-span” size=“2”>最主要是要在<span =“apple-style-span” style="font-family: arial; “>waveform Graph中滑鼠點擊"波型上的某兩點”，
<font =“apple-style-span” face=“arial” size=“2”>假設點擊在第5000筆資料，那要算出5000筆的前100比總和的平均，
<span =“apple-style-span” style="font-family: arial; "><font =“apple-style-span” size=“2”>第二次點擊也是…
<font =“apple-style-span” size=“2”><font =“apple-style-span” face=“arial”>然後相減算出<span =“apple-style-span” style="font-family: 新細明體, serif; ">ΔF值…
<span =“apple-style-span” style="font-family: 新細明體, serif; "><font =“apple-style-span” size=“2”>
<font =“apple-style-span” face=“新細明體, serif” size=“2”>所以想請問滑鼠的部分與讀取TXT檔某個行列資料。

煩請提攜一下…剛接觸不久…

[QUOTE=Gallant]<font size=2 =“apple-style-span”>抱歉，可能沒表示清楚。

最主要是要在waveform Graph中滑鼠點擊"波型上的某兩點"，
假設點擊在第5000筆資料，那要算出5000筆的前100比總和的平均，
第二次點擊也是..
然後相減算出ΔF值...

所以想請問滑鼠的部分與讀取TXT檔某個行列資料。
抱歉沒說清楚。
煩請提攜一下...剛接觸不久..

下面程式給你參考,滑鼠按下試第1點,放開是第2點.
