Generating Digital waveform.

[rasur]

Hi,

   I am trying to generating a graph.The input data should be taken from .xls file(input voltage and input time).

  Requirement:-

   First it has to browse the file and read the input data from the .xls file.

   after reading the data from the .xls file it has to plot the graph according to the input data.

   Example->in .xls file

           Input voltage                Input Time

              2v                                      0.2ms

              4v                                       4ms

so it has to plot according to the above input data.

the input voltage(2v) should stay upto 0.2ms of time in the graph.
