# plot a performance envelope (changable ellipse) [closed]

I am learning by myself to use Mathematica. I am quite new actually. I'd like to plot something that resembles the picture below, but here's the thing, I want to know if there is a possibility to creat a chart where I can add X and Y values, allowing it to plot the graphic but if I change the values, the graphic would change. I hope I make myself clear, English is not my first language. Thanks in advance

• Welcome to MSE. There are several Wolfram Demonstration projects on ellipses that might be close to what you are looking for. e.g. this. – Rohit Namjoshi Dec 3 at 1:00
• What is the relationship between the ellipse and the X and Y values? – C. E. Dec 3 at 8:55
• X is tension, larger values than Y; Y is differential pressure – MasterLD Dec 3 at 20:06
• Take a look at the help for Manipulate, which facilitates interaction. – Yves Klett 17 hours ago
