Can you provide all of your code? I'm thinking a bit more context could be useful.

Ok thank you. What are you hoping the plot will look like? Your vector is so long that it is impossible to see any of the background which would make it easier to see the actual values being plotted. Similar to the following:
plot(rand(1000000,1))
Do you no longer have two columns to plot?
