Labview Program to Plot numerical data written to and Read from a Text File

This is a simple Labview Program to write numerical data,that may come from any sensor or instrument interfaced with PC,to a text file and then read that data to plot that data on a waveform chart.In this code,to simulate the generation of numerical data a random number generator function has been used which writes data to text file and upon reading that written data plots that data on a waveform chart.Labview 2012 has been used for development of this Labview code.There are two tabs on the front panel one writing data to text file and the other one is for reading data from text file.
The screenshots of the Front Panel are shown in Figure 1 & Figure 2 below:
