How can I limit the axes on ternary diagram using ternplot?

Hello,

I have been using the ternplot function that I downloaded from the file exchange. My problem at the moment is that all my data lie within one corner of the ternary diagram. This is due to the fact that the solution I am examining is composed almost entirely of one of the components. Does anyone know how I can present the ternary plot where I can "home in" on one particular region. Zooming in manually after I do the plot is possible however I would like to limit the axes directly.

Thanks
