您是要将同一个.txt 里的两组不同数据, 一组在第一个waveform chart 里显示, 另一组在第二个waveform chart 里显示?

恩.

从TXT读两组数据，是2D Array？如果是，则Index Array。

最主要的是什么格式的波形数据。有了这些信息，然后决定是如何读取它转化为展示用途。

请上传您的数据文件.

The main thing is about what format is the waveform data. With that information, it is then decide how to read it in and transform it for displaying purposes.

For tab-delimited text file, please refer to this discussion

Hi Meiyan,

If you read my previous reply, you should already got the idea on how to read tab-delimited data and convert them to array.

What you need to do is...

1. Ensure that the *.txt file was saved as tab-delimited values (see attached modified from yours) 
2. Read Characters From File
3. Convert the Spreadsheet String to Array, remove column header strings and transform each row's tab-delimited values into array
4. If necessary, you may convert the output string array to numeric array for graph plotting etc.

不好意思，我在完全不了解labview的情况下被要求做一个project，苦做一个月发现不合格，结果自己是越来越糊涂，见谅，我会好好看的，谢谢您一直耐心讲解。
