The pd.DataFrame method is used to return a data frame from data structures like lists, dictionaries, and a list of dictionaries. While the header row contains a string data type, the elements inside can be numerical. What Is a Data Frame?Īs discussed above, a data frame is a storage unit that stores data across multiple rows and columns. It can store heterogeneous data which means, a data frame contains data of multiple types. This article focuses on the key concepts of a data frame and its index, and how we can use this index as values for the X-axis in plotting a graph. When we try to visualize the data frame, we can also use its index as values for the X-axis while plotting. We can also visualize a data frame with the help of this library. ![]() We can visualize and manipulate the data if we understand what the data frame holds.Ĭoming to visualization, the Matplotlib library of Python is very much useful in carrying out data visualization and manipulation tasks. If the Index is chosen correctly, it might help us in understanding the data frame better. We can choose the column that best describes the data frame as an index. The Index of a data frame is its most crucial feature. An index can be numeric data, a string literal, a datetime entity, and so on. The index of a data frame can be any column that is found relevant to the data. That is, it stores data in rows and columns. A data frame is a common storage unit of the Pandas library that is similar to a table. While we are talking about the index of a data frame, it is essential to know what a data frame is. It can be specified while creating the data frame or we can even set the index after analyzing it. A Data Frame Index is a column in the data frame that represents the data frame as a whole. ![]()
