Pandas Plot Color Gradient
pandas.io.formats.style.Styler.background_gradient # Styler.background_gradient(cmap='PuBu', low=0, high=0, axis=0, subset=None, text_color_threshold=0.408, vmin=None, vmax=None, gmap=None) [source] # Color the background in a gradient style. The background color is determined according to the data in each column, row or frame, or by a given gradient map. Requires matplotlib.
Parameters. Let us see how to gradient color mapping on specific columns of a Pandas DataFrame. We can do this using the Styler.background_gradient () function of the Styler class.

If there is an intuitive color scheme for the parameter you are plotting If there is a standard in the field the audience may be expecting For many applications, a perceptually uniform colormap is the best choice; i.e. a colormap in which equal steps in data are perceived as equal steps in the color space. Pandas' Styler.background_gradient function is used to apply a color gradient to each cell of the data frame.
In the code you entered, with the axis=None parameter, the gradient is applied to the entire DataFrame (both along rows and columns) and the vmin and vmax values are fixed for the entire DataFrame. Pandas styling exercises, Practice and Solution: Create a dataframe of ten rows, four columns with random values. Write a Pandas program to make a gradient color mapping on a specified column.

The background_gradient method maps values to colors using a colormap (cmap), with YlGn creating a yellow-to-green gradient. Use matplotlib colormaps or custom ones for variety. For visualization basics, see plotting basics in Pandas.
Text and Font Customization Customize text properties like font weight, color, or alignment. pandas.io.formats.style.Styler.text_gradient # Styler.text_gradient(cmap='PuBu', low=0, high=0, axis=0, subset=None, vmin=None, vmax=None, gmap=None) [source] # Color the text in a gradient style. The text color is determined according to the data in each column, row or frame, or by a given gradient map.

Requires matplotlib. Parameters: cmapstr or colormap Matplotlib colormap. lowfloat.
Output: User-Defined Function Using Seaborn Library Using color palette for gradient fill in DataFrame: By importing the light palette of colors from the seaborn library, we can map the color gradient for the background of the data frame. Color gradients are a feature that can be added to plots to make them more visually appealing to readers. We will also use the Titanic Dataset and random data to create sample visualizations.
pandas.DataFrame.plot # DataFrame.plot(*args, **kwargs) [source] # Make plots of Series or DataFrame. Uses the backend specified by the option plotting.backend. By default, matplotlib is used.
Parameters: dataSeries or DataFrame The object for which the method is called. xlabel or position, default None Only used if data is a DataFrame. ylabel, position or list of label, positions, default.
