Assume you have a data of 12 lines that time sensitive due to the
dates they would be filled. Each line would be a number for that
month.

I get the whole, adding NA() to remove the zero so that it does not
plot. However, I wanted to take it a step further...

Currently, the graph will plot up to the month you are in. Let's
assume it is June. As for the X-axis it shows from January to
December, but the graph does not plot anything after June due to the
NA() function to remove any zero values.

If you have 12 lines to signify each month, is it possible so that the
categories seen on the X axis as well as what is plotted, to only show
from January to June instead of January to Decemeber but stops
plotting at June?
