ResourceFunction["PlotVector"] accepts the following options:

"ArrowSize" | Medium | specify the size of the arrowhead |

"LocatedVector" | False | whether to draw vectors from the initial point (the first point of the list) to the terminal point (the second point in the list) |

VectorStyle | RGBColor[.3,.4,.7] | specify the style of the vector |

Plot the vector (1,1) located at the origin:

In[1]:= |

Out[1]= |

Plot a list of vectors located at the origin:

In[2]:= |

Out[2]= |

Plot the vector (2,1) located at the point (-1,1):

In[3]:= |

Out[3]= |

Plot a list of vectors located at the point {1,2}:

In[4]:= |

Out[4]= |

Plot a list of vectors located at different points. The first list is a list of vectors and the second is a list of initial points:

In[5]:= |

Out[5]= |

Specify a vector located at a point in three different ways:

In[6]:= |

Out[6]= |

The default arrow size is Medium, which corresponds (roughly) to "ArrowSize"→1.5:

In[7]:= |

Out[7]= |

Change the arrow size of each vector:

In[8]:= |

Out[8]= |

A located vector from the first point to the second point:

In[9]:= |

Out[9]= |

Setting the located vector to False draws the vectors located at the origin:

In[10]:= |

Out[10]= |

A list of lists of pairs of vectors with the option "LocatedVector"→True draws located vectors from the first point in each sublist to the second point in each sublist:

In[11]:= |

Out[11]= |

Without the option being set, the second tuple in each list gives the located point, and the first tuple gives the direction:

In[12]:= |

Out[12]= |

Change the style of the vectors:

In[13]:= |

Out[13]= |

Set both the arrow size and style for each vector:

In[14]:= |

Out[14]= |

The length of the list of vectors must be the same as the length of the list of initial points:

In[15]:= |
