why the vectors in the quiver plot are so small ?

8 views (last 30 days)
Hi,
I am reading the data from the csv file and plotting quiver using the code below but the vectors plotted there are not visible or one can say very small in size? is anyone know why? it supposed to show results something like attached image Export.61y83iia.0000.zip but it look like image untitled.jpg
Code:
%Specifying the folder where all the excel file for the last timestep are
a = readtable('Export.6tuxmp0w.000002.csv');
X=a{:,5};
Y=a{:,6};
U=a{:,9};
V=a{:,10};
quiver(X,Y,U,V);

yes,sir,may be use
quiver(X,Y,U,V,2);
such as
clc; clear all; close all;
[x,y] = meshgrid(0:0.2:2,0:0.2:2);
u = cos(x).*y;
v = sin(x).*y;
figure
quiver(x,y,u,v)
figure
quiver(x,y,u,v,2)
