How to use Python to draw pattern
This article introduces the relevant knowledge of "how to use Python to draw patterns". In the operation of actual cases, many people will encounter such a dilemma. Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!
Globe wiring
According to the display of the globe area, add lines to the corresponding position graph, the perfect linear globe detailed code is as follows:
`import plotly.express as pxdf = px.data.gapminder.query ("year = = 2007") fig = px.line_geo (df, locations= "iso_alpha", color= "continent", # "continent" is one of the columns of gapminderprojection= "orthographic") fig.show`
The display result is: * *
Add lines to the map
Add latitude and longitude after drawing the corresponding map, and then draw the corresponding lines according to the longitude and latitude. The detailed code is as follows:
Importplotly.graph_objectsasgofig = go.Figure (data=go.Scattergeo (lat = [3.86,53.55], lon = [73.66,135.05], mode = 'lines',line = dict (width = 2, color =' red'),) fig.update_layout (geo = dict (resolution = 50 showland = True,showlakes = True,landcolor = 'rgb (203,203,203)', countrycolor = 'rgb (204,204,204)', lakecolor = 'rgb (255,255,255)', projection_type = "equirectangular") Coastlinewidth = 3herolataxis = dict (range = [20,60], showgrid = True,dtick = 10), lonaxis = dict (range = [- 100,20], showgrid = True,dtick = 20),) `fig.show`
The display results are as follows:
The final benefit-3D picture appreciation
Finally, add a 3D image appreciation, and the detailed code for making the image is as follows:
# Import package importplotly.graph_objectsasgofromplotly.subplotsimportmake_subplotsimportnumpyasnpN = 50fig = make_subplots (rows=2, cols=2,specs= [[{'is_3d': True}, {' is_3d': True}], [{'is_3d': True}, {' is_3d': True}]], print_grid=False) for i in [1 for j in 2]: fig.append_trace (go.Mesh4d (x = (50*np.random.randn (N)), y = (20*np.random.randn (N) Z = (40*np.random.randn (N)), opacity=0.5,), row=i, col=j) `fig.update_layout (width=700, margin=dict (ritual 9, lumped 9, bimodal 9, tweak 9)) # fix the ratio in the upper left subgraph to the cube fig.update_layout (scene_aspectmode='cube') # manually force the z axis to be displayed as twice the size of the other two fig.update_layout (scene2_aspectmode='manual',scene2_aspectratio=dict (x, y) 1 Fig.update_layout (scene3_aspectmode='data') # use "data" as the default value to automatically generate well-proportioned content fig.update_layout (scene4_aspectmode='auto') # display fig.show`
The display results are as follows:
