Hello,
i am working in origin pro,
i want to plot a graph as like a pdf attached but with black and white lines.
here radial axis varies from 0 to 1. and angular axis from 0 degree to 60 degree.and third axis which is depend on both radial and axial gives non intersecting lines.
how can i read the data from plot for replot.

... origin pro?

Then why are you here?

It is not clear from your message that this has anything to do with R.

I found that the optim() function does not always reach the real minimum. Is it because the solution is trapped at a local minimum?

Thanks!

Maybe?
  Optimization is a large and difficult topic, and it's pretty much
impossible to say anything without more details.  Depending on your
problem, you might be able either draw some pictures or compute
second derivatives; if the matrix of second derivatives of the
function you're minimizing is positive definite then you're at a local
minimum.
