## How to Create a Candlestick Chart in Matplotlib? Updated on 18-Apr-2023 14:56:30
Candlestick charts are a popular way to visualize stock market data. They show the opening, closing, high, and low prices of a stock or security for a given time period. A candlestick chart consists of a series of vertical bars or "candlesticks", where each candlestick represents one time period. The top and bottom of each candlestick represent the highest and lowest prices traded during that period, while the body of the candlestick represents the opening and closing prices. In this tutorial, we will explore codes where we will use Matplotlib, a popular data visualization library in Python, to create a ... Read More

## How to Annotate Matplotlib Scatter Plots? Updated on 24-Mar-2023 15:14:36
Introduction Scatter plots are an essential tool for illustrating the connection between two continuous variables. They help us identify potential anomalies, patterns, and trends in the data. Yet, scatter charts can also be hard to interpret when there are numerous data points. If comments are made, some points of interest in a scatter plot could be easier to observe and understand. In order to make Matplotlib scatter plots more understandable, this article will examine how to annotate them. Syntax ax.annotate(text, xy, xytext=None, arrowprops=None, **kwargs) text − Text to be displayed in the annotation. xy − (x, y) coordinates ... Read More

## How to Adjust the Number of Ticks in Seaborn Plots? Updated on 24-Mar-2023 14:44:38
Introduction Ticks are tiny symbols that Matplotlib uses to represent the positions of data points on both axes of a plot. They may be positioned to best fit the data range and are used to highlight certain locations on the x and y axes. Usually, ticks may be labeled to indicate the precise values they stand for. In the python package Seaborn, there are two functions, namely, xticks() and yticks() that can be used for adjusting the ticks of a given graph. Syntax To adjust the number of ticks in Seaborn plots, we can use the following syntax − ... Read More

## How to Adjust Marker Size in Matplotlib? Updated on 24-Mar-2023 14:38:06
Introduction In a plot, a marker is a symbol that designates a single data point. Size, color, and shape are just a few of the attributes that may be changed. Markers are commonly used in conjunction with other charting methods to enhance the readability and comprehension of data. With Matplotlib, a wide variety of marker shapes are provided, including circles, squares, triangles, diamonds, and more. It is possible to alter the marker size to draw attention to crucial details or to develop more aesthetically pleasing plots. We'll show you how to alter the marker size in Matplotlib using examples of ... Read More
