Thanks, Andy. That works! Now the problem is how I can use the 1d arrays to construct 3d plots.
Now I have many 1d arrays: x, y, z, variable1, variable2, ..., etc. Unfortunately, they are AMR data, not regularly indexed, (in fact they are TecPlot ascii data, but ParaView could not read them correctly for some reason, this is another issue, though). I would like to make 3d plots, 2d slice, or at least 1d cuts. I am OK to use Python interface but might need some instruction how to create 3d data from these flattened 1d arrays. I guess there are some tutorials to convert numpy array to vtk arrays, I might start from that. Then I need to convert the row data ParaView GUI reads in to numpy array then to vtk array? I have attached the data if anyone can kindly try it. At least it is a valid TecPlot file which other people tested using TecPlot.
