![]() ![]() Select the second grid file and click Open.This is the grid with the X component or angle component, depending on the coordinate system. Select the first grid file and click Open.Click Home | New Map | Specialty | 2-Grid Vector.The 2-grid vector map draws vectors based on two grid files containing the X and Y components or the magnitude and direction components. See Gridding directional data, such as wind speed and direction, in Surfer for more information If you have a data file with X,Y, direction, and magnitude data or starting XY and ending XY data, you can grid the data twice, once to create a grid of directions or changes in X and once to create a grid of magnitudes or changes in Y. Click Home | New Map | Specialty | 1-Grid Vector.The 1-grid vector map calculates the maximum slope and slope direction from the Z values in the GRD file to draw vectors with magnitude and direction. If you have an XYZ data file, you can grid the data and create a 1-grid vector map. Surfer can create vector plots from a single grid file, or from two grid files individually containing direction and magnitude information in either polar or Cartesian coordinates. ![]()
