Operating System:Window VISTA
I need to plot the contour graph from my 3D data without interpolation or extrapolation. I know that I have to choose the regular gridding method when the x, y data are evenly spaced or the sparse method when they are not. But when I did, it seemed like the original data were seriously distorted.
Below is the original that I ploted using the other software.
I thought that the original 3D data are evenly spaced, so I choosed the regular gridding method to convert the dataset to matrix and plot it. It looked like below,
It seems like that it erased some data for some reason. 
So I tried with sparse method and below is the result,
Everything is gone. 
So, please somebody let me know how I fix it?

Hi,
Please send your XYZ data or your project to tech support so they can look at what is going on with your particular data.
I also wanted to comment that in version 8, you can select your Z column of your XYZ data and directly select Plot->Contour->XYZ Contour. This performs triangulation on the raw data and directly plots a contour plot without creating a matrix. This method may be useful if you do not want the matrix and just want to see a contour plot. If you double-click on the plot, the Plot Details dialog has a Contour Info tab on the right side that has options for smoothing etc.
