6. How to plot angles in ArcView Given a txt or dbf(dbase iv) file with x y and angle fields Ie.Y X angle * note that 360-ambroseangle = AV angle 0 0 45 0 300 90 300 0 270 300 300 180 In Arcview select tables, Add txt file. With A View selected, Add Event Theme (under the view menu bar), id which field is x and y Once the theme has been generated dbl click theme to edit properties, select an arrow, color, size, etc.. Use the Advanced button to set the rotation field to the column containing angle. *You can also plot the magnitude of the vector by using legend type graduated symbol) You may export a View or theme layout to a eps, jpg… Or convert the Event Theme to a shapefile and import to ENVI.

Arrows still do not start at the line but are centered at the point. Plot then was rotated in Photoshop From MatLab coordinates to ‘real’
