The problem is happening because you are viewing 3d plot from a 2d projection. The variables allow for complete control over the maximum and minimum values for x and y axis. I have no idea what data you have, how it is structured, and how it correlates to the two seemingly unrelated plots that you have shown. This matlab function plots coordinates in 3d space. We also discuss some identities relating these functions, and mention.

The definition allows for a variable level of accuracy to the mathematically. Plot your series of points with the function plot x, y.
If you are going to change the plotted data or make a new plot and want to control the color range, then read about the caxis. Then, use the sphere function to plot three spheres with different numbers of faces into different tiles of the chart by specifying the axes. Notice that the titles and labels that you defined for the first plot are no longer in the current figure window. How to plot an arc or parabola matlab answers matlab. This matlab function plots a twovariable symbolic expression or function fx,y over the range 2pi 0 and kk2. Call the tiledlayout function to create a 2by2 tiled chart layout. The satellites orbit can be expressed in polar coordinates as r p 1.
I would like to plot c as a surface, with particular value of c being defined by a colour. If you carefully set the mesh grid for x and y, then you can calculate the corresponding value for z. Finally, we use matlab to simulate its dynamic construction process. When a satellite orbits the earth, the satellites orbit will form an ellipse with the earth located at one of the focal points of the ellipse. Mathematica plotting a hyperbolic paraboloid pringles.
