Functions to change aspects of Quiver plots in Matlab.Color, length of vector, length of head and angle of the head can easily be changed.
I provide two functions.SetQuiverColor and SetQuiverLength.The function SetQuiverColor is heavily based on the answer by Suever found on Stackoverflow forum
Implements the MATLAB given quiver/quiver3 function adding a color coding depending on magnitude
function to make the way the script works easily understandable.quiverC3D creates a 3D quiver plot and adds a color coding. The color coding isgiven by the absolut values of the component vectors. Large
Color quiver based on magnitude or angle.Also, support uniform sampling by averaging or taking the fastest velocity within each grid cell.
patches which are used for drawing heads and tails.quiv = cquiver(x, y, u, v, 'cdata', 'angle') set color based on angle.quiv = cquiver(x, y, u, v, 'sampling', h) plots quiver plotat uniform grid where grid
This is a modified version of the function quiver3 with color plot.
This is a modified version of the function quiver3 to plot velocity vectors as arrows with components (U,V,W) at the points (X,Y,Z) with the color corresponding to C data. From the idea of Suever:
Quiver plot with filled triangles head
QUIVER_TRI(x,y,u,v,headsize,headangle,width) same as before, plus% setting of the quiver body width%% QUIVER_TRI(x,y,u,v,headsize,headangle,width,col) same as before, plus% setting of the color%% See also QUIVER.
Quiver (vector) with a reference vector or color code on a map or Cartesian axes.
This function is a substitute for the standard versions of quiver and quiverm available using a vanilla release of matlab. This version assumes a 2D vector field is being plotted using a gridded flow
Maps unit vectors into corresponding RGB color on the RGB cube. Intended for visualizing normal vectors on 3D point clouds or mesh data.
Maps unit vectors into corresponding RGB color on the RGB cube. Intended for visualizing normal vectors on 3D point clouds or mesh data as color instead of quiver3 which is sometimes hard to see the
Produce a 3D quiver of arrows with many visualization options
This quiver3D differs from the basic quiver3 in that it allows far more options for visualization. Based on the 'surf' command, you can produce color-based visuals of your data via the multiple
This function can be used to create various plots of errors related to Lab color coordinates.
This function can be used to illustrate error values related to datapoints of CIE-L*a*b* color coordinates. A larger error is plotted by a larger marker, or in quiver plots by longer vectors.This is
This function provides an improvement over the QUIVER3 technique for visualizing 3D vector fields.
and contain the corresponding position and velocity% components. QUIVER3D automatically scales the arrows to fit.% % QUIVER3D(X,Y,Z,U,V,W,COLOR) provides an input argument for coloring%
Creates a color quiver plot with arrows colors according to the magnitude of the vector.
This is a modified version of the function quiver [from C.M. Thompson] to plot velocity vectors as arrows with components (u,v) at the points (x,y) with the color corresponding to the magnitude of
Generates a quiver plot colored according to vector magnitude and/or user specified axis boundaries.
quiverwcolorbar adds functionality to the original quiver function by assigning color to the arrows according to the vector magnitude. The corresponding colorbar spans the minimum and maximum values

A simple, easy-to-use visualization tool for vector fields. ベクトル場の発散、回転を可視化表示します
This demo allows the user to input an arbitrary 2-D vector field as a function of Cartesian (x,y) and/or polar coordinates (r,t). The value of the vector field is shown with arrows using the QUIVER

Vectorized and flexible arrow plot function in 2-D
The function also accepts any standard patch parameter/value pair like 'FaceColor', 'EdgeColor', 'LineWidth', etc.It can be used to plot a personalized arrow at coordinates X,Y with length L and azimuth
