line graph-source data not taking

[polepalle2000]

sirs, i am experiencing this difficulty:

I am trying to draw line graph picking the data from excel sheet.
The values in first column is used for x axis. The Values next column are taken from yaxis .The values in this column are calculated using formula .On asking to finish i find all the values zero on the graph.
Please help

Without seeing the data, we can only guess. The only guess I have: if the formula is outputting data that looks like a number, but is really a number formatted as text, it would graph as if it were a zero.
