我可以在动画中更改注释的arrowprops（属性）吗？

Question

我一直在寻找一种方法来更改使用动画中注释的arrowprops参数创建的箭头的属性（matplotlib）。

箭头是这样创建的：

axes.annotate('', xy=(-1, -1), xytext=(-1, -1), xycoords='data', textcoords='data',
                  arrowprops=dict(arrowstyle='<-', color='blue', linewidth=2))

我希望能够在动画期间更改箭头的颜色。

注释的箭头存储在# Default server configuration # server { listen 80 default_server; listen [::]:80 default_server; listen 443 ssl # SSL configuration # # listen 443 ssl default_server; # listen [::]:443 ssl default_server; # # Note: You should disable gzip for SSL traffic. # See: https://bugs.debian.org/773332 # # Read up on ssl_ciphers to ensure a secure configuration. # See: https://bugs.debian.org/765782 # # Self signed certs generated by the ssl-cert package # Don't use them in a production server! # # include snippets/snakeoil.conf; root /var/www/html; # Add index.php to the list if you are using PHP index index.html index.htm index.nginx-debian.html; server_name localhost; ssl_certificate /etc/nginx/ssl/nginx.crt; ssl_certificate_key /etc/nginx/ssl/nginx.key; location / { try_files $uri $uri/ /index.php; root /var/www/html; index index.html index.htm index.php; } location ~ \.php$ { include /etc/nginx/fastcgi_params; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /srv/www/app.snuba.com/public_html$fastcgi_script_name; error_page 405 = $uri; } # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /\.ht { # deny all; #} } 属性中。您可以通过arrow_patch设置颜色。
