The features available are the sepal width, sepal length, petal width and petal length. We will use the Iris dataset which contains information about iris flower species setosa, versicolor and virginica. Z = np.random.randint(low=5, high=100, size=15)įig.add_trace(go.Scatter3d(x=x, y=y, z=z, mode="markers"))Įvery feature is considered a dimension in data science, the high the features the better the accuracy to classify data belonging to different labels. Then we will create a Scatter3d plot by adding it as a trace for the Figure object. To create 3D Scatter plots it is also straightforward, first let us generate random array of numbers x, y and z using np.random.randint(). L.append()įigure = go.Figure(layout=go.Layout(title="Simple Scatter Example", xaxis=go.layout.XAxis(title="X"), yaxis=go.layout.YAxis(title="Y")))įigure.add_trace(go.Scatter(x=l,y=l, mode="markers", name=f" Distribution ]įf.create_distplot( for ele in d], group_labels= for ele in d], show_hist=False) In order to have the dotted shape format of the plot, we need to assign the attribute mode the value markers. To generate random data, we will use the np.random.randint() method from Numpy, we will specify the two boundaries (lowest and highest numbers) in addition to the size of the array (in our case, let's use 50). We will try to plot 4 scatter plots within the same figure. In this section, we will learn to plot dotted type of plots (unlike continuous lines in the first section). X = sorted(np.random.random(100) * 10 - 5)įig=go.Figure(layout=go.Layout(title="Sigmoid Plot",xaxis=xaxis, yaxis=yaxis))įig.add_trace(go.Scatter(x=x, y=y, marker=dict(color="red"))) Multiple Scatter Plots

To change the color of the lines, we assign a dictionary to the marker attribute and specify color as a key and the name of the color (in our case, red) as a value.

Here is another example of displaying the graph of the sigmoid function (usually used as an activation function in deep learning) which is defined by the formula: s(x) = 1/ (1 + exp(-x)). x = įig = go.Figure(layout=go.Layout(title="Simple Line Plot", xaxis=xaxis, yaxis=yaxis)) Here is a simple example of displaying the graph of the function f(x) = 2x. We can add traces by calling the method add_trace() to the Figure object.

Traces: Which is a set of graphical objects Plotly offers like Scatter, Bar, Histogram plots, etc.

We can add the layout by assigning a value to the layout attribute of the Figure object, which is an instance of the class go.Layout

Layout: Which is the metadata and the external information that appears to the graph like the main title and the names of the axis.

To create figures using Plotly, we need to create an instance of the Figure class, the main components of this class are: We're running the init_notebook_mode() method to enable the use of plotly library without registering and getting an API key for that.

Once you have everything install, open up a new jupyter lab and import these libraries in the first cell: import pandas as pd If you're not using Anaconda environment, then you must manually install plotly extension for jupyter lab: $ jupyter labextension install jupyterlab-plotly Make sure you install the required libraries: pip install numpy The development environment that we will be using throughout this tutorial is a Jupyter lab, if you don't have it installed, this link should help you install it.

In this tutorial, we will learn how to use Plotly visualization tool to create dynamic plots in Python. Nothing is better than well designed figures to give a clearer view of reports and do accurate conclusions for them, hence the use of the visualization tools is a key thing when it comes to the exploratory data analysis step that should be undergone by data scientists.
