How to make dropdown menu using plotly.

The Dropdown menu is nothing but a part of the menu button, in which it is been displayed on the screen all the time. Here every menu button is being associated with a menu widget and when we click on that button it can show the choices for that menu button. There are four methods possibly in plotly which are used to modify the charts or graphs by using this update menu method which is as follows:

Restyle It will modify the data or data attributes. Relayout It is used to modify the layout attributes. Update It will modify the data and layout attributes. animate used to start or pausing the animation.

Step 1 - Import libraries

import plotly.graph_objects as go import numpy as np

Step 2 - Creat random function

np.random.seed(52) My_Random_xx = np.random.randint(2, 202, 200) My_Random_yy = np.random.randint(2, 202, 200)

Step 3 - Add dropdown and Plot graph

My_plt = go.Figure(data=[go.Scatter( x=My_Random_xx, y=My_Random_yy, mode='markers',) ]) My_plt.update_layout( updatemenus=[ dict( buttons=list([ dict( args=["type", "scatter"], label="Sactter graph", method="restyle" ), dict( args=["type", "bar"], label="Bar Chart", method="restyle" ) ]), direction="down", ), ] ) My_plt.show()

So from the above figure:

The first "My_plt" is about assigning the values to particular variables like we have taken 2 randome variables in which there are random values. The "x" will consist of "My_random_xx" which are having random values and similarly for "y". After that we have created a Dropdown with the help of "Update_layout" in which we have updated the menus and specified the "buttons" as "Sactter graph" and "Bar chart". The Direction is about in which direction the dropdown should be.
