Hi! I'm using Ternary to make plots of different fish phenotypes. It would be really useful to me if the different sides of the plot could have different scales reflecting the different scales of the traits I'm working with. For example, the code

TernaryPlot(axis.labels = c(seq(0, 10, by = 1), seq(0, 100, by = 10), seq(0, 50, by = 5)))

would yield a plot that goes from 0-10 on one side, 0-100 on the second, and 0-50 on the third. Thanks for building the package. I'm really enjoying it so far!

I was almost to post my own issue on this regard. I also support the request of @lsw5077 enabling customized ranges for the three axes. I also agree about the usefulness of this package :wink:.

kamapu commented 3 years ago

Oh! I found one argument against this desire (I was thinking about three independent variables). I realized when the three plotted variables are not complementary (the sum of the three values should be 100) it won't properly work. Thus, the only possible alternative is to use fractions (all scales from 0 to 1) instead of percentages.

Hi, thanks for the suggestions; and glad to hear that you are finding the package useful.

As @kamapu notes, it's not clear how a ternary plot might work when the plotted variables are not complementary. @lsw5077 , are you able to provide a simple example so I can understand what data would be plotted and how this would work in practice?

ms609 commented 2 years ago

I'm closing this issue because I'm not clear exactly how this would work. (Perhaps you had in mind something akin to a Holdridge plot?) Please do re-open the issue if you are able to describe in a little more detail the behaviour you require.
