Dash Python Framework
Dash Python Framework: Dash for Interactive Web Apps
With Dash, you can create interactive web apps with elements
- such as buttons, dropdowns, sliders, range sliders, checkboxes,
- date pickers, and more. In this course, you'll learn how to get
- started with Dash, beginning with installing Dash and various
- extension libraries using the pip package installer. You'll move on
- to building web apps using Dash and the Plotly Express library.
- You'll also work with two other important Dash extension libraries
- - the Dash Core Components library and the Dash HTML Components
- library. You'll put all of these libraries together while exploring
- some of the default interactivity features, such as zooming and
- panning charts. You'll create a callback app where the title of a
- chart updates based on the values on a range slider before creating
- a more refined app with a callback that updates the chart itself
- and not just the title. Finally, you'll build a fully-fledged
- interactive scatter plot.
Dash Python Framework: Leveraging Dash with User Input & Dash DataTable
If you've used Dash before, you'll know how quickly the native
- HTML table abstraction from dash_html_components can become
- complicated and cumbersome due to the need to create a TR tag for
- each row and then individual TD tags within each TR tag for each
- cell value. Using the dash DataTable abstraction mitigates all of
- these weaknesses. In this course, you'll practice this technique
- before using the Dash data table to display data in the form of
- tables in Dash apps. You may also know that you can harness the
- power of Dash using HTML components or components from the Dash
- Core Component library. In this course, you'll also get a chance to
- work with user input and buttons in Dash apps using the most
- appropriate components.
Dash Python Framework: Creating Widgets in Dash Apps
The Dash DAQ library can be used to represent data in ways that
- correspond to real-world physical measurement mechanisms, such as
- switches, thermometers, knobs, dials, gauges, LED displays, and
- tanks. In this course, you'll learn how to work with this library.
- In addition, you'll practice creating widgets using Dash core
- components. You'll also create Dropdowns, TextAreas, RadioButtons,
- and Checklists. Finally, you'll cover two important aspects of
- building web apps - building tabbed apps with different controls on
- each tab and accepting user upload of files. You'll build a web app
- that accepts a file for upload, either via drag-and-drop or via
- direct user navigation, and then checks whether the file is a .csv
- file and if so, displays the contents of that file in a
- DataTable.
