Can not make wind plot using mnetcdf,mwind.

[RyosukeDTomita]

problem fixed!

Hi!
I want to make vector figure to display netcdf wind data.
So, I write a code showing below.

from Magics.macro import *
ncfile = "../data/surface_2020-12-28_0" #netcdf
output = output(
                output_formats                = ['png'],
                output_name                   = "windtest",
                output_name_first_page_number = "off",
                output_width                  = 800)
center = page(
             layout           = 'automatic',
             page_x_length    = 45.,
             page_y_length    = 20.,
             page_id_line     = 'off',# erase ECMWF logo↲
             page_x_position  = 0.,
             page_y_position  = 0.,)
area = mmap(
            subpage_map_projection        = "cylindrical",
            subpage_lower_left_longitude  = 120,
            subpage_lower_left_latitude   = 25,
            subpage_upper_right_longitude = 150,
            subpage_upper_right_latitude  = 50,)

coast = mcoast(
            map_coastline_land_shade         = "on",
            map_coastline_land_shade_colour  = "cream",
            map_grid_line_style              = "dash",
            map_grid_colour                  = "charcoal",
            map_grid_thickness               = 2.0,
            map_grid_latitude_increment      = 10,
            map_grid_longitude_increment     = 10,
            map_label                        = "on",
            map_coastline_colour             = "black",
            map_coastline_thickness          = 2.7,
            )
# My problem!
vector = mnetcdf(
        netcdf_type                 = "vector",
        netcdf_filename             = ncfile,
        netcdf_x_component_variable = "u10", #something wrong?
        netcdf_y_component_variable = "v10", #something wrong?
        )

wind = mwind(
        legend                = "on",
        wind_field_type       = "arrows",
        wind_arrow_thickness  = 1,
        wind_thinning_factor  = 1,
        wind_arrow_calm_below = 0.5, # min
        wind_arrow_head_ratio = 0.3,
        wind_arrow_colour     = 'evergreen',)
plot(center,output,area,coast,vector,wind)

Then, I run this code. Unkown Error is occured.↓

# error
Magics-warning: Netcdf MagException:  Can not find variable ---> x
Magics-ERROR: Netcdf MagException:  Can not find variable ---> x

I think "netcdf_x_component_variable" is needed other information but, I'm not sure what kind of information is needed.

Here is information of data .
I tryid to replace "u10" "v10" to 1,2(index number), but I cannot fix this problem.

I also gogled this problem but, I cannot find answer.
If you have the idea to fix this problem, plase tell me.
