graphs bya macro

[Adam Brave]

Hi
If I had a table like the one bellow how would I specified in a macro a graph with the first column in the X axis and with the numbers arranged in two series defined on Y axis? Until now I can put the numbers in two series defined on the Y axis but the first column doesn't appear on the X axis. Instead of the words it appear the numbers 1,2,3 and 4....
