Similarly we can plot the BER for different receivers in same window by using EXcel.
It is easy to plot graph in Excel with good quality of image and with accuracy.
We can change the parameters of axes. We can use logarithmic scale of decimal scale.
I am uploading the image of BER with Logarithmic scale vs Length of fiber.
We use logarithmic scale because BER has very less value in terms of 10^-x and x should be as greater as possible.
Hope it would make you understood.
