Export XYZ Chart


Upon creation of an XYZ Chart, the chart/data are available for export to the following formats using the Export buttons on the toolbar (third-party software must be installed).

Microsoft Outlook

Google Earth

My Charts as a .jpg file

Surfer (by Golden Software)

oExporting to Surfer before creating the contour generates only the .dat file, so you can use your own gridding options (e.g. nearest neighbor, kriging etc.).

oExporting to Surfer after creating the contour generates the .dat, .grd (nearest neighbor interpolation), and the plotted contour. You can review the contour, then go back to the .dat file and change the gridding options, if desired.


Note: Surfer exports require a Plus Graphics License or higher.
