Why can't I see the Hypervolume graph? And how can I connect the paroto front into a 3D mesh?

Hello, everyone, I am using Octopus these days. But I have met 2 problems, Can anyone help me solve these?

1. I cannot see the Hypervolume graph in the left of Octopus interface as shown below, I cannot find something wrong. Does anyone has the same problem with me?

2. Another thing is that I want to connect the pareto front into a 3D solution mesh(like picture below, from the paper of Robert Doe, Mathew Aitchison). But I don't know how to do it. There aren't any tutorials or discussions on the web. Can anyone help me?

Thank you very much if you could do me a favor.  Thanks~

Yours,

Anxiao
