I intend to plot `y=cos(cX)`

in Excel, where `c`

is a constant produced in first cell of column C using `RANDBETWEEN(-50,50)`

. Column 'A' represents `X`

values (from -100 to 123) and column B contains `f(x)`

values generated using the function `f(x)=cos(cX)`

.

Then I select columns A and B and hit insert chart (2D line chart), which gives the following plot:

This is not What I wanted. I want X values to be plotted on horizontal axis and Y values to be plotted on the vertical axis. Here, it is inverse. How can I make it show the way I want?
