I have a .csv file with 4 column of data. I found something from another thread which allows me to display data from an Excel file in an array. I'm having trouble with the following items:
1) I need to show 4 column of data but I can't seem to find a way to add more elements to the Invoke node so I'm stuck with being able to display only 2 columns of data.
2) Why can't I take my output and put it in an array and then display it on a waveform chart?
Please take a look at the attached VI. I made notes in the block diagram. When I try to attach the Excel data to a chart, it says that the type of the source is a string while the type of the sink is double. How can that be when the Excel file only has integers?!
Please help.
Thank you.
