Help Center Help Center. Quiver properties control the appearance and behavior of a Quiver object. By changing property values, you can modify certain aspects of the quiver chart. 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.

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. To specify a marker and display arrowheads, set the Marker property instead.

Quiver matlab

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. Call axis equal to use equal data unit lengths along each axis. This makes the arrows point in the correct direction.

Example: '--or' is a red dashed line with circle markers. Use them to calculate z. This makes the arrows point in the correct direction. I have used ideas from this page and this page. Cancel Copy to Clipboard. LineSpec — Line style, marker, and color character vector string. Therefore, the color codes " FF" , " ff" , " F80" , and " f80" are equivalent. Therefore this. Sharp vertical and horizontal lines, specified as 'on' or 'off' , or as numeric or logical 1 true or 0 false. Call axis equal to use equal data unit lengths along each axis. Specify the directional components using these values. Setting this property sets the associated mode property to manual mode.

To specify a marker and display arrowheads, set the Marker property instead. The BusyAction property determines callback queuing behavior only when both of these conditions are met:. Add a quiver plot and title to each axes. Load sample data that represents air currents over North America. A value of 0. For example, a scale of 2 doubles the length of arrows, and a scale of 0. The tails of the arrows are positioned at the data points. Plot Vectors Normal to Surface. 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. The default value of "auto" uses the same color as the Color property. I have used ideas from this page and this page. When you manually set these properties of an object, MATLAB disables automatic color, line style, and marker selection for that object and allows your selection to persist, regardless of the value of the SeriesIndex property. Then, display contour lines in the same axes. Set the underlying IconDisplayStyle property of the Annotation object to one of these values:. Line style, marker, and color, specified as a character vector or string containing symbols.
