In Origin, data arranged in a block of worksheet cells can be treated as a virtual matrix. Such virtual matrix can be used to create a contour or 3D plot. The following is an example to illustrate the differences between creating surfaces from matrix data versus virtual matrix data.
The following are all the graph types that can be created from a Virtual Matrix.
To create contour or 3D plot from a virtual matrix, you could select the worksheet cell blocks, click the Plot menu to generate a plot and bring up the plotvm Dialog. (e.g. Plot:3D Surface:Colormap Surface or the other graph types that supports creation from virtual matrix.
Also, you may refer to the tutorial Creating Intersecting Surface Plots from Worksheets.
Note: if you select a whole worksheet, the virtual matrix will be dynamic updated when you add or delete columns/rows in the source worksheet. If you select a worksheet cell block from a certain column/row to the end column, for example from 5th column to end, and want the virtual matrix be dynamic updated, right click on the triangle button to the right of Input and select Dynamic Ends.
