title: How to change values on y-axis for lattice xyplot
body: <p>I have an xy plot in lattice on which I'm showing four different things. The plot looks like this right now. The values for pink line range from 1 to 15000, however, values for other lines range from 20 to 300. This is why all lines other than pink seem static. However, there are fluctuations in them but I feel the graph isn't showing them property because of yaxis. Is there a way I can shorten the yaxis such that the graph is better representing the other lines as well?</p>

  <p>This is how it looks when I don't plot the pink line all together. This shows there are fluctuations which I'd like to show. </p>
