我正在尝试使用箭头来绘制带有u和v风成分的纬度和经度数据，其中轮廓图给定地图的坐标或纬度限制西部和东部的南北和经度限制。 我有使用quiver的数据，如下所示：

我正在尝试使用这样的箭头来获取这些变量，我得到一个看起来很好的情节：
quiver(lons, lats, uu, vv);
我正在尝试使用此代码使用此usamap覆盖地图，以地图轮廓形式叠加在箭袋图上：
latlimf = [17.4154, 18.2805];
lonlimf = [-126.8954, -125.9866];
usamap(latlimf, lonlimf);
问题是，即使我使用usamap来保持箭袋，但hold on请求会以空白地图的形式获得覆盖 <箭头曲线图。
