How to use Python Visualization Library Pandas_Alive

This article mainly explains "how to use the Python visualization library Pandas_Alive". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn how to use the Python visualization library Pandas_Alive.

Preface

Recently, it has been found that a similar visual library "Pandas_Alive" in Chinese can not only contain dynamic bar charts, but also draw dynamic curve products, bubble charts, pie charts, maps and so on.

It also takes a few lines of code to replace the dynamic chart.

The recommended installation version is 0.2.3 and the matplotlib version is 3.2.1.

At the same time, you need to install tqdm (display progress bar) and descartes (place map-related libraries).

Otherwise, there will be an error, and it is estimated that the author's requestment.txt does not include these two libraries.

Well, after a successful installation, you can date this third-party library and directly choose to load the local file.

Import pandas_alive as pd import pandas covid_df = pd.read_csv ('data / covid19.csv',index_col = 0pm parseurs = [0]) covid_df.plot_animated (filename =' examples / example-barh-chart.gif',n_visible = 15)

When you start to learn the library, you can reduce the data, so that the time to generate GIF will be faster.

For example, in the following practice, basically only about 20 days of data are selected.

For other diagrams, we can check the API description of the official document to understand.

Let's take a look at other replacement methods for dynamic charts.

Dynamic bar graph elec_df = pd.read_csv ("data / Aus_Elec_Gen_1980_2018.csv", index_col = 0pm parseurs = [0], thousands of yuan =',') elec_df = elec_df.iloc [: 20 example-electricity- generation:] elec_df.fillna (0). Plot_animated ('examples / example-electricity- generation-australia.gif',period_fmt = "% Y", title =' Australian Power Source for 1980-2018')

02 dynamic bar chart

Covid_df = pd.read_csv ('data / covid19.csv',index_col = 0Magnum parseurs = [0]) covid_df.plot_animated (filename =' examples / example-barv-chart.gif', direction = 'vaulting pencils _ visible = 15)

03 dynamic graph

Covid_df = pd.read_csv ('data / covid19.csv',index_col = 0 data parseurs = [0]) covid_df.diff () fillna (0). Plot_animated (filename =' examples / example-line-chart.gif',kind = 'line',period_label = {' x: 0.25,0.9})

04 dynamic area map

Covid_df = pd.read_csv ('data / covid19.csv',index_col = 0Magnum parseurs = [0]) covid_df.sum (axis = 1) .fillna (0). Plot_animated (filename =' examples / example-bar-chart. Gif', kind = 'bar', period_label = {' x: 0.1,0.1,0.9}, enable_progress_bar = True,steps_per_period = 2 Period_length = 200)

05 dynamic scatter plot

Max_temp_df = pd.read_csv ("data / Newcastle_Australia_Max_Temps.csv", parse_dates = {"Timestamp": ["Year", "Month", "Day"]},) min_temp_df = pd.read_csv ("data / Newcastle_Tustralia_T. , parse_dates = {"Timestamp": ["Year", "Month", "Day"]},) max_temp_df = max_temp_df.iloc [: 5000 merged_temp_df:] min_temp_df = min_temp_df.iloc [: 5000 merged_temp_df:] pd. Merge_asof (max_temp_df,min_temp_df,on = "Timestamp") merged_temp_df.index = pd.to_datetime (merged_temp_df ["Timestamp"] .dt.strftime ('% Y /% m /% d')) keep_columns = ["lowest temperature (degrees Celsius)", "maximum temperature (degrees Celsius)"merged_temp_df [keep_columns] .resample (" Y "). Mean (). Plot_animated (filename = 'examples / example-scatter-chart.gif',kind = "scatter", title = "maximum and minimum temperature Newcastle, Australia")

06 dynamic pie chart

Covid_df = pd.read_csv ('data / covid19.csv',index_col = 0Magnum parseurs = [0]) covid_df.plot_animated (filename =' examples / example-pie-chart.gif',kind = "pie", rotationlabels = True,period_label = {'x cards: 0,'y stories: 0})

07 dynamic bubble chart

Multi_index_df = pd.read_csv ("data / multi.csv", title = [0,1], index_col = 0) multi_index_df.index = pd.to_datetime (multi_index_df.index,dayfirst = true) map_chart = multi_index_df.plot_animated (category = "bubble", file name = "examples / example-bubble-chart.gif", x_data_label = "longitude", y_data_label = "latitude" Size_data_label = "case", color_data_label = "case", vmax = 5 stepsperfect perennial period = 3) True,period_length = 500, dpi = 100)

08 geospatial point chart

Import geopandas Import pandas_alive Import contextily GDF = geopandas.read_file ('data / NSW-covid19- case by postcode.gpkg') gdf.index = gdf.postcode GDF = gdf.drop (' zip code', axis = 1) result = gdf.iloc [: 20] result ['geometry'] = gdf.iloc [:,-1:] [' geometry'] map_chart = result.plot_animated (filename = 'examples / example-geo-point-chart .gif " Basemap_format = {'source':contextily.providers.Stamen.Terrain})

09 general geographical chart

Import geopandas Import pandas_alive Import contextily GDF = geopandas.read_file ('data / Italy-covid-region.gpkg') gdf.index = gdf.region GDF = gdf.drop (' region', axis = 1) result = gdf.iloc [: 20] result ['geometry'] = gdf.iloc [:,-1:] [' geometry'] map_chart = result.plot_animated (filename = 'examples / example-example-example-geo-polygon-chart.gif' Basemap_format = {'source':contextily.providers.Stamen.Terrain})
