visualization of data

Hi everybody,

I would like to visualize data which I collected with another LabVIEW application. The data is stored into a *.txt file. The following example shows few lines of it:

.
.
.
23.05.05 16:05:01 0.05
23.05.05 16:05:34 0.18
23.05.05 16:06:05 0.04
23.05.05 16:06:37 0.07
23.05.05 16:07:08 0.08
23.05.05 16:07:40 0.06
.
.
.


As you can see, the first part is the date followed by the time the data was collected. The last number is an index of produced power by an photovoltaic solar power plant (displayed in watts). Every day a new file is generated (e.g. C:\Messdaten_23.05.05.txt).
Do you have an idea of a simple vi which is able to display this data into a graph with the date and time at the x-axis and the prduced power at the y-axis? It's not important to design it perfect, but I need a tip how to seperate the lines into date/time and value and put it to the graph.

Thanks for your help!

Best regards,
Dennis

Hi Paulo,

thanks for your fast reply, but unfortunately I'm using LabVIEW 7.0 and I'm not able to open your VI. I think you use a newer version of LabVIEW. Is there a possibility for me to open it anyway? Or another way you can show me your thoughts/ideas?

Greets,
Dennis

Hey Paulo,

thanks for your great help. After customizing the format string (...I need a %f.%f at the end, because of the values (e.g.) 0.12 ) the vi works fine. Now it does exactly what I wanted to do.
Perfect work!

Greets, Dennis
