Read data from text file and write to Intensity Graph

[johndoe17354]

I am attempting to take data from a text file made within the same VI. However, I am struggling to figure out how to read that data and represent it in an intensity graph. My text file contains 3 columns, and I would like to read the last 2 columns. I am trying to create a heat map of a griddle using two thermocouples, the thermocouple data is the last two columns in my text file. I have tried to read the delimited spreadsheet with a tab delimiter, but it doesn't seem to care.

That's how the data looks like in a waveform graph:

I didn't implement any filtering of those empty lines…

How should your heatmap/intensity graph look like?

Can you please share PNG of this VI

I suggest to built a designated reader.vi besides your data-generating .vi

e.g. 

then you can focus on the main task, which is interpolation...
