x: It represents the x-coordinates of the arrow location. It can be either a 1-D or a 2-D array or a sequence. y: It represents the y-coordinates of the arrow location. It can be either a 1-D or a 2-D array or a sequence. u: It represents the x-components of the arrow vector. It can be either a 1-D or a 2-D array or a sequence. v: It represents the...
Quiver plot is a type of 2-D plot make up of vector lines in shape of arrows. These plots are mainly used to visualize gradients. The basic syntax of a quiver plot is:
The plot below shows one quiver arrow, which is starting from (0,0) and is pointing towards the up and the right side at (1,1).
We saw one arrow plot, now lets add another arrow. Both the arrows are starting from the same point (0,0) and plotting one of them towards (1,1) and another towards (0,-1). Set the axis limits to (-1.5,1.5).
The 2-D surface filled with arrows is created by using meshgrid() method of Numpy. To create this surface, we first need to create a set of arrays named X and Y, which will represent the starting positions of x and y of each arrow on the quiver plot, respectively. Here, we also have to denote u and v in the plot as an array of directions of the qui...
This is an optional step that specifies the color of the arrow. This requires the dimensions which are same as that of position and direction arrays.
This is how you use the quiver plot in matplotlib in Python. This serves as a very helpful tool in many phases. Hope this helped. Still have any doubts or questions, do let me know in the comment section below. I will try to help you as soon as possible. Happy Pythoning!
Learn how to create quiver plots in Python using matplotlib library. A quiver plot is a 2-D plot that shows velocity vectors as arrows with components (u, v) at points (x, y).
Learn how to make quiver plots in Python using Plotly. A quiver plot displays velocity vectors as arrows on a grid. See examples, code, and references.

12. Mai 2021 · Python. Tags: Matplotlib. Ein Quiver-Diagramm ist ein Plottyp, der Pfeile mit Richtungskomponenten U und V an den durch X und Y angegebenen kartesischen Koordinaten anzeigt. Mit der Funktion quiver (), die die folgende Syntax verwendet, können wir in Matplotlib auf einfache Weise ein Quiverdiagramm erstellen: quiver (x, y, u, v) wo:
