Work on LABView project

I have LabView project which I need some help with. To design a VI that can be used to show how the voltage rises across a capacitor in a simple RC circuit when excited by a step function. The output from the VI will consist of two plots displayed on one XY graph. One plot will be the input wave Vin = Eu(t) (V) displayed from t = -10 (ms) to T1 (ms) The second plot will be the voltage across the capacitor VC = E(1 – e -t/RC) displayed from t = 0 to t = T1 (ms) The VI will run continuously allowing all inputs to be varied. The inputs to the VI will perform the following functions: 1. Set the number of points for the VC plot, default 100. 2. Set the final time T1 in (mS) default 50 (mS). 3. Set the resistor value in (Ω) default 500 (Ω). 4. Set the capacitor value in (μF) default 20 (μF). 5. Set the height of the input step function default 10(V). The outputs from the VI will display the following: 1) The Time Constant T = R.C 2) The two plots on an XY graph as specified above. I need a report a few pages explaining how the VI designed works. I already have a like a sample VI to start which needs working on.
