Redux Tutorial Step By Step With Example From Scratch is the topic we will cover. I will teach you Redux step by step. Redux is quite an excellent State Managment Framework usually used with React.js library. In Single Page Application, data management at client side is far more complicated than just imagine. Now, you are familiar that, ReactJS is relying on the State of the application. However, In React.js state management is possible, but when the application gets bigger and bigger, unwanted errors and data changes are detected, and which module has changed which state and which view is updated, all these matters get complex, and we feel like, we trapped in our application. Facebook gives the solution. Its developer has created one State management pattern called Flux.
It complements React’s composable view components by utilizing the unidirectional data flow. When the users interact with views, the views propagates actions through a central dispatcher, to the various stores that hold the application data and logic, which updates all of our views that are affected.
Flux has so many stores, and each store is using different small part of the state or data of our application. In other words,** each different module has its store.**

This Matplotlib cheat sheet introduces you to the basics that you need to plot your data with Python and includes code samples.
Data visualization and storytelling with your data are essential skills that every data scientist needs to communicate insights gained from analyses effectively to any audience out there.
For most beginners, the first package that they use to get in touch with data visualization and storytelling is, naturally, Matplotlib: it is a Python 2D plotting library that enables users to make publication-quality figures. But, what might be even more convincing is the fact that other packages, such as Pandas, intend to build more plotting integration with Matplotlib as time goes on.
However, what might slow down beginners is the fact that this package is pretty extensive. There is so much that you can do with it and it might be hard to still keep a structure when you're learning how to work with Matplotlib.
DataCamp has created a Matplotlib cheat sheet for those who might already know how to use the package to their advantage to make beautiful plots in Python, but that still want to keep a one-page reference handy. Of course, for those who don't know how to work with Matplotlib, this might be the extra push be convinced and to finally get started with data visualization in Python.
You'll see that this cheat sheet presents you with the six basic steps that you can go through to make beautiful plots.
Check out the infographic by clicking on the button below:
With this handy reference, you'll familiarize yourself in no time with the basics of Matplotlib: you'll learn how you can prepare your data, create a new plot, use some basic plotting routines to your advantage, add customizations to your plots, and save, show and close the plots that you make.
Matplotlib is a Python 2D plotting library which produces publication-quality figures in a variety of hardcopy formats and interactive environments across platforms.

In no time, this Bokeh cheat sheet will make you familiar with how you can prepare your data, create a new plot, add renderers for your data with custom visualizations, output your plot and save or show it. And the creation of basic statistical charts will hold no secrets for you any longer.
Boost your Python data visualizations now with the help of Bokeh! :)
The Python interactive visualization library Bokeh enables high-performance visual presentation of large datasets in modern web browsers.
Bokeh's mid-level general-purpose bokeh. plotting interface is centered around two main components: data and glyphs.
The basic steps to creating plots with the bokeh. plotting interface are:
>>> from bokeh.plotting import figure >>> from bokeh.io import output_file, show >>> x = [1, 2, 3, 4, 5] #Step 1 >>> y = [6, 7, 2, 4, 5] >>> p = figure(title="simple line example", #Step 2 x_axis_label='x', y_axis_label='y') >>> p.line(x, y, legend="Temp.", line_width=2) #Step 3 >>> output_file("lines.html") #Step 4 >>> show(p) #Step 5
Under the hood, your data is converted to Column Data Sources. You can also do this manually:
>>> import numpy as np >>> import pandas as pd >>> df = pd.OataFrame(np.array([[33.9,4,65, 'US'], [32.4, 4, 66, 'Asia'], [21.4, 4, 109, 'Europe']]), columns= ['mpg', 'cyl', 'hp', 'origin'], index=['Toyota', 'Fiat', 'Volvo']) >>> from bokeh.models import ColumnOataSource >>> cds_df = ColumnOataSource(df)
>>> from bokeh.plotting import figure >>>p1= figure(plot_width=300, tools='pan,box_zoom') >>> p2 = figure(plot_width=300, plot_height=300, x_range=(0, 8), y_range=(0, 8)) >>> p3 = figure()
>>> p1.circle(np.array([1,2,3]), np.array([3,2,1]), fill_color='white') >>> p2.square(np.array([1.5,3.5,5.5]), [1,4,3], color='blue', size=1)
>>> pl.line([1,2,3,4], [3,4,5,6], line_width=2) >>> p2.multi_line(pd.DataFrame([[1,2,3],[5,6,7]]), pd.DataFrame([[3,4,5],[3,2,1]]), color="blue")
Selection and Non-Selection Glyphs
>>> p = figure(tools='box_select') >>> p. circle ('mpg', 'cyl', source=cds_df, selection_color='red', nonselection_alpha=0.1)
>>> from bokeh.models import HoverTool >>>hover= HoverTool(tooltips=None, mode='vline') >>> p3.add_tools(hover)
>>> from bokeh.models import CategoricalColorMapper >>> color_mapper = CategoricalColorMapper( factors= ['US', 'Asia', 'Europe'], palette= ['blue', 'red', 'green']) >>> p3. circle ('mpg', 'cyl', source=cds_df, color=dict(field='origin', transform=color_mapper), legend='Origin')
>>> from bokeh.io import output_notebook, show >>> output_notebook()
>>> from bokeh.embed import file_html >>> from bokeh.resources import CON >>> html = file_html(p, CON, "my_plot") >>> from bokeh.io import output_file, show >>> output_file('my_bar_chart.html', mode='cdn')
>>> from bokeh.embed import components >>> script, div= components(p)
>>> from bokeh.io import export_png >>> export_png(p, filename="plot.png")
>>> from bokeh.io import export_svgs >>> p. output_backend = "svg" >>> export_svgs(p,filename="plot.svg")
Inside Plot Area
>>> p.legend.location = 'bottom left'
Outside Plot Area
>>> from bokeh.models import Legend >>> r1 = p2.asterisk(np.array([1,2,3]), np.array([3,2,1]) >>> r2 = p2.line([1,2,3,4], [3,4,5,6]) >>> legend = Legend(items=[("One" ,[p1, r1]),("Two",[r2])], location=(0, -30)) >>> p.add_layout(legend, 'right')
>>> p.legend. border_line_color = "navy" >>> p.legend.background_fill_color = "white"
>>> p.legend.orientation = "horizontal" >>> p.legend.orientation = "vertical"
>>> from bokeh.layouts import row >>>layout= row(p1,p2,p3)
>>> from bokeh.layouts import columns >>>layout= column(p1,p2,p3)
Nesting Rows & Columns
>>>layout= row(column(p1,p2), p3)
>>> from bokeh.layouts import gridplot >>> rowl = [p1,p2] >>> row2 = [p3] >>> layout = gridplot([[p1, p2],[p3]])
>>> from bokeh.models.widgets import Panel, Tabs >>> tab1 = Panel(child=p1, title="tab1") >>> tab2 = Panel(child=p2, title="tab2") >>> layout = Tabs(tabs=[tab1, tab2])
Linked Axes >>> p2.x_range = p1.x_range >>> p2.y_range = p1.y_range
>>> p4 = figure(plot_width = 100, tools='box_select,lasso_select') >>> p4.circle('mpg', 'cyl' , source=cds_df) >>> p5 = figure(plot_width = 200, tools='box_select,lasso_select') >>> p5.circle('mpg', 'hp', source=cds df) >>>layout= row(p4,p5)
