The Sparse XYZ worksheet to matrix conversion is similar to the Regular XYZ conversion (i.e. X and Y data values must be regularly spaced), except that in the case of the Sparse conversion, missing XY pairs are acceptable. Using proper X and Y step setting, sparse method will fill the value in the grid nodes like:
After conversion, Origin will generate the following matrix:
With the sparse matrix, you can create a 3D plot with Z values plotted only at select XY values, as in this 3D bar plot:
1. Import the file \Samples\Matrix Conversion and Gridding\Sparse.dat.
2. Type xyz_sparse iz: = Col(3) rows: = 3 cols: = 5 in the command window.
