Choose 2D Color Map from the Data menu, then use the current selection or full table. Output decides whether to create a new figure or add to an existing one.
Data Range
Selection: rows 1-11, columns 1 to 3
Full table: 11 rows, 3 columns

Matrix Input
By default, the current selection is used as the full Z-value matrix; X/Y coordinates are configured separately.
Use current selection as matrix inputRows 1-11, columns 1 to 311 rows · 3 columns
Step 3
Choose data format
Use XYZ Columns for coordinate rows. Use Matrix Input for regular grids, matrix data, or Raman mapping matrices.
Step 4
Set coordinate source and create
Matrix Input uses the current selection as the Z-value matrix. X/Y coordinates can be generated by index, by range, from the first row, or from the first column.
