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, quiver matlab. The vectors X and Y represent the location of the base of each quiver matlab, and U and V represent the directional components of each arrow.

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.

Help Center Help Center. The quiver plot has arrows with directional components dlat and dlon at the geographic coordinates specified by lat and lon. For example, the first arrow originates from the point lat 1 and lon 1 , extends horizontally according to dlon 1 , and extends vertically according to dlat 1. By default, the function scales the arrow lengths so that they do not overlap. When scale is a positive number, the function automatically adjusts the lengths of arrows so they do not overlap, then stretches them by a factor of scale.

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.

Example: '--or' is a red dashed line with circle markers. 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. Toggle Main Navigation. The symbols can appear in any order. 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. Toggle Main Navigation. Load sample data that represents air currents over North America. Close Mobile Search. Trial software. Display the gradient vectors as a quiver plot. When you need access to the object elsewhere in your code, you can use the findobj function to search for the object based on the Tag value. First, create a grid of x- and y- values that are equally spaced. See Also.

Help Center Help Center. 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.

Disable automatic scaling so that arrow lengths are determined entirely by U and V by setting the scale argument to 0. Tags quiver. Specify Arrow Color. Thank you for your kind comment. Clicked object — Access properties of the clicked object from within the callback function. Search Answers Clear Filters. By default, the object does not display markers. Main Content. Use this property to display a context menu when you right-click the object. If it cannot, then the HitTest property has no effect. Use this property to store arbitrary data on an object. Y — y -coordinates of bases of arrows scalar vector matrix. Do you have any suggestion? Adjust the display so that the vectors appear normal to the surface by calling axis equal.
