Hello Everyone, Can someone please tell me how to make a best fit point in a contour plot I am trying- $splot "test1.dat" with lines "<echo '135 0.40'" But it is showing an error. I want a point at 135,0.40 Thank you

Thank you.. Its making now.. echo command i saw somewhere, where it was used to make a point so i tried to combine it with splot command Thanks..

There is one more issue in my contour plot... The axes are not proper... Both the axes should have the same origin point... the y axis is on the vertically flipped side of x axis How can I resolve it ...

Please show your actual set of gnuplot commands. I'm neither clairvoyant nor standing right behind you.

I just tried it set view map... it worked... Thank you. Also I want to know does gnuplot automatically calculates the 1,2,3.. sigma ranges ? I have three columns.. x,y,z. For contour plot I am using the above commands with - "$set cntrparam levels discrete 2.3,6.2,11.8" which are 1,2 and 3 sigma levels respectively for 2 parameter correlation. But in my z column these sigma values are not present still I am getting a plot.. I am confused that what does it mean ? What I know is- for particular z values of confidence levels contours are drawn for x and y for corresponding z values set by the user.. Am I correct ?

If you say so ... > But in my z column these sigma values are not present still I am getting a plot.. I am confused that what does it mean ? gnuplot simply makes a surface with height z out of your xy-gridded datapoints, and then interpolates contour lines onto that at the specified levels. Neither gnuplot nor I know what "sigma" is. > What I know is- for particular z values of confidence levels contours are drawn for x and y for corresponding z values set by the user.. Am I correct ? > Confidence levels of what? I repeat, I am NOT clairvoyant. I cannot read your mind. Contours are made by a straightforward interpolation, there is no stochastic element.
