Plot multiple instances of the same point

[jabber25]

I am trying to "weight" some data I have and then plot it to get a regression line. In the attached file, I want to divide the distance traveled by 5, to give more weight to observations that had a further distance traveled. In other words, an observation over 100 distance would have a higher weight than one over 20, by a factor of 5. Is there a way to have an xy scatter plot that would take this into account and plot 20 observations for the 100 distance and only 4 for the 20 distance?

Thanks for any help you can offer!
