Why rescale data?

[Bisaloo]

Hi,

Thank you for this package! I may be missing something obvious but why rescale data? It makes it impossible to do some semi-complex operations such as:

library(ggplot2)
library(gg3D)

data(iris)
iris2 <- iris
iris2$Petal.Width <- iris2$Petal.Width + 10

g <- ggplot(iris, aes(x=Petal.Width, y=Sepal.Width, z=Petal.Length, color=Species)) + 
  theme_void() +
  axes_3D() +
  stat_3D()

g2 <- g +
  stat_3D(aes(x=Petal.Width, y=Sepal.Width, z=Petal.Length, color=Species), iris2)

Here, we expect g and g2 to be different since g2 has an additional layer with different data but they look just the same.

That's a good point. I usually only use 3D for quickly visualizations, hence scaling minimizes how much work I have to do prior to plotting.

I will probably make scaling optional in an update. For now, a workaround would be to combine iris and iris2 into a single dataframe.

Good point. I guess my example was not so good. I actually want to use different geom for my two datasets. This is why I am using two datasets.

Would you like me to submit a PR to try and fix this?

Please do; happy to have you work on it.

It's harder than what I anticipated (but you probably already knew that 😃).

perspbox output will depend on the limits for x, y and z. Those limits can change between the different stat_3D layers. I think we would need a way to somehow exchange information between layers so limits in perspbox can be set for all layers. I'm not sure it's possible...

What do you think? Maybe you already gave it some thought and have more ideas than me.

You could add limit parameters, xlim, ylim, zlim, specified in the stat_3D or aes call. These would add dummy points for the perspective transformation. It might also be possible in the more flexible geom system, but I haven’t bothered to learn that.
