Use dot notation to query and set properties. Arrow color, specified as a three-element RGB triplet, a hexadecimal color code, a color name, or a short name. An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color.

The default value is 0.

Load sample data that represents air currents over North America. For this example, select a subset of the data. Create a quiver plot of the subset you selected. The vectors X and Y represent the location of the base of each arrow, and U and V represent the directional components of each arrow. By default, the quiver function shortens the arrows so they do not overlap.

Help Center Help Center. For example, the first arrow originates from the point X 1 and Y 1 , extends horizontally according to U 1 , and extends vertically according to V 1. By default, the quiver function scales the arrow lengths so that they do not overlap. If U and V are vectors, then the x -coordinates of the arrows range from 1 to the number of elements in U and V , and the y -coordinates are all 1. If U and V are matrices, then the x -coordinates of the arrows range from 1 to the number of columns in U and V , and the y -coordinates of the arrows range from 1 to the number of rows in U and V. When scale is a positive number, the quiver function automatically adjusts the lengths of arrows so they do not overlap, then stretches them by a factor of scale. For example, a scale of 2 doubles the length of arrows, and a scale of 0. When scale is 'off' or 0 , such as quiver X,Y,U,V,'off' , then automatic scaling is disabled. Markers appear at the points specified by X and Y.

For example, the first arrow originates from the point X 1 , Y 1 , and Z 1 , extends in the direction of the x -axis according to U 1 , extends in the direction of the y -axis according to V 1 , and extends in the direction of the z -axis according to W 1. By default, the quiver3 function scales the arrow lengths so that they do not overlap. If Z is a vector, then the x -coordinates of the arrows range from 1 to the number of elements in Z and the y -coordinates are all 1. If Z is a matrix, then the x -coordinates of the arrows range from 1 to the number of columns in Z and the y -coordinates range from 1 to the number of rows in Z. When scale is a positive number, the quiver3 function automatically adjusts the lengths of arrows so they do not overlap, then stretches them by a factor of scale. For example, a scale of 2 doubles the length of arrows, and a scale of 0. Markers appear at the points specified by X , Y , and Z. If you specify a marker using LineSpec , then quiver3 does not display arrowheads.

Rupak Loodh on 3 Aug A problem with quiver, when the x and y axis units are incommensurate, or when there are no y axis values as in this case , is that the arrows can get distorted. Note If you change one data source property to a variable that contains data of a different dimension, you might cause the function to generate a warning and not render the graph until you have changed all data source properties to appropriate values. Marker fill color, specified as "auto" , an RGB triplet, a hexadecimal color code, a color name, or a short name. William Rose Before accept your answer. Markers appear at the points specified by X and Y. Note The properties listed here are only a subset. Thanks for your answer. Disable Automatic Scaling.

Help Center Help Center. The quiver plot has arrows with directional components dlat and dlon at the geographic coordinates specified by lat and lon.

By default, the quiver function scales the arrow lengths so that they do not overlap. Use the quiver3 function to plot the vectors and the surf function to plot the surface. Example: 0. I want the opposite, so I have flipped cosd and sind. Call axis equal to use equal data unit lengths along each axis. For example, the first arrow originates from the point X 1 , Y 1 , and Z 1 , extends in the direction of the x -axis according to U 1 , extends in the direction of the y -axis according to V 1 , and extends in the direction of the z -axis according to W 1. Again thanks so much for your help. The input argument Y to the quiver function determines the y -coordinates. By default, the quiver function shortens arrows so they do not overlap. LineSpec — Line style, marker, and color character vector string. For more information about the clipping behavior, see the Clipping property of the axes. You cannot add or remove children using the Children property. This makes the arrows point in the correct direction.
