Using Text File Data to Plot out a histogram

[LexenZ]

Hi professionals of NI,

I have a text file data attached with 3 columns of data and I would like to plot it out with a histogram.

Unfortunately, the create histogram data doesn't let me extract out the values I would like to plot it out...

I have viewed from some of the older threads on how to do it, sadly it was a very long thread and the Vis, images were corrupted.

Does anyone have a great solutions for this....? Really appreciate it!

Hi Lexen,

Do you mind to explain HOW you want those data to be plotted?

Hi there Dark Knight,

Thanks for the response. As shown from the graph I have to make out something like this.

As for "plot it out" meaning I think it would be when I load the test file into the file path, the list of 3 columns would show out in the graph say C will the red color, G will be blue and D in green....

Hi Lexen,

no need to use ExpressVIs:

I used the simple Histogram function, there is an advanced one where you can provide more parameters. And I used LV2011, so the ReadSpreadsheetFile function looks different to the one in recent LabVIEW versions.

in the graph say C will the red color, G will be blue and D in green....

I don't know what CGD means, but changing plot properties should be easy enough!

Dear Dark Knight,

Omg your such a godsend, I have managed to work it out and did it as shown! 

Thank you so much! 

I have another issue I am not sure if I should post it here or create another post again?
