i have the following graph and need to convert it in to plot type graph...

actually i have the following type of graph (see attachment) and need to convert it to a plot type of graph (see attachment too) between temperature and elevation.is there any way to extract the information at a particular radial location. through any matlab feature

[Walter Roberson]

Do you have the data used to create the graph, or do you only have the graph itself in the form of an image?

[ali ahmed]

Yup ,actually i had used quickersim to generate the graph in the first place ,but the glitch is that the matrix used to plot is of order of 21356×1 . So is there any way to use plot command at a particular location...???

[Walter Roberson]

Unfortunately the SSL certificates for quickersim.com are invalid so I cannot check out the documentation for it.

There are some things that can be done about plotting at particular locations, but it is not clear how the 21356×1 corresponds to particular locations? Is it like a 281 x 76 array of data ?

Answer 1

as u can se in the attachment

[Walter Roberson]

Is the p variable possibly position information to go along with the T variable?

[ali ahmed]

yup it basically contains coordinates (x,y) for nodes

[Walter Roberson]

scatteredInterpolant() probably.

x = p(1,:);
y = p(2,:);
F = scatteredInterpolant(x(:), y(:), T(:));
minx = min(x); maxx = max(x);
miny = min(y); maxy = max(y);
[X, Y] = ndgrid( linspace(minx, maxx, 200), linspace(miny, maxy, 200) );
pT = F(X, Y);
surf(X, Y, pT, 'edgecolor', 'none')

I am not sure what the "radial" is intended to correspond to, or whether "elevation" is intended to be y, or is intended to be T, or something else.

thanks walter... :-)

as u can see in the highlighted part
