Reading and Controlling External Data Files

Reading and controlling External Data files

Utilities, External Data maps the panel shown here.

Use the File: prompt to define the external data filename, then Read File... to read it in and store it in memory.

Thereafter the key parameters described above (contour bands, symbol type and size, data value display) will be used to initialise this panel, but you can change them interactively at will.

The turning off/on of display of external data on plots is controlled by Display active in this model.

Some examples. Note that displaying the underlying model in grey usually works well as it gives good contrast with the coloured symbols, as does using transparency to show underlying structure.

Here the symbols in the plot above have been changed to rectangular, varying; and display of data values has been turned on.

Here symbols have reverted to fixed size squares, and two "beams" have been added to demonstrate their appearance.
