how can i do rms data trending using labview

[hafizzuddin]

Hai guys,currently i'm doing a vi to minitor a vibrating motor. each experiment consist of few position and each position will have its own overall RMS value. before this, i just read and take the rms value to plot the trending graph using excel. the question is how can i store this RMS value and use it to show/create a graph to show the trending of the RMS vibration motion using LABVIEW. 

here i attached my block diagram ad an exmaple of trending which i did using excel. thank you

I am no guru but I would use a storage vi to store results to file updating each interation and put the values into a chart for realtime monitoring.  A block could be added to append the front panel to a report when complete.  I'll attach a small section where I am doing something similar. Somewhere you would have to address timing as well.
