Seeking help as a beginner

I have just started using HYSYS, with version 8.4. After reviewing some materials, I want to create a phase diagram for bubble points and dew points. The vapor fraction and pressure have been entered, as well as the composition of the stream; but I don’t understand how it is stated in the book that HYSYS will calculate the temperature or pressure of the dew point and bubble point. Where can this be seen? And later, different temperatures and pressures were tried (with the same components), but the graphs remained the same. Why is that? I hope the experts can help answer this question. Thank you.
No need for HYSYS; there’s just one issue: you enter the pressure, composition, and gas phase fraction – that’s all. How can a phase diagram be created from that?
Thank you for the reply. Later I found a tutorial video and, after watching it, I understood why I hadn’t gotten any calculation results before. But when I entered those parameters, there was indeed a phase diagram available; I’m not sure why. The phase diagram drawn later is similar to this one, with no bubble points as well. Is this related to the components?
