The code examples and results presented in this tutorial have been implemented in a Jupyter Notebook with a python (version 3.8.3) kernel having pandas version 1.0. With this, we come to the end of this tutorial. You can see in the above chart has “Scores” as its x-axis label, and “Distribution of Math Scores of the Class” as its title.įor more on histograms and their formatting in matplotlib, refer to our tutorial on matplotlib histograms. In addition, pandas also provides utilities to compare two Series or DataFrame and summarize their differences. # create the histogramĪx.set_title("Distribution of Math Scores of the Class") pandas provides various facilities for easily combining together Series or DataFrame with various kinds of set logic for the indexes and relational algebra functionality in the case of join / merge-type operations. Let’s go ahead and add the x-axis label and title to our plot. Since the returned plot is a matplotlib axes object, you can apply any formatting that would work with matplotlib charts. For instance, you can add the axes labels, chart title, change colors and fonts, etc. You can also customize the formatting of the chart. Note that the resulting plot is a matplotlib histogram chart.įor more on the pandas series plot() function, refer to its documentation.
The above histogram show that a large number of students got scores between 60 to 80. Return a reshaped DataFrame or Series having a multi-level index with one or more new inner-most levels compared to the current DataFrame. For example, let’s see its usage on the “math_scores” series created above. DataFrame.stack(level- 1, dropnaTrue) source Stack the prescribed level (s) from columns to index. To create a histogram from the series values we’ll pass kind='hist' to the pandas series plot() function. We now have a pandas series containing the scores of students in a Math class. You can see the top five values of the series object above. First, we’ll create a sample pandas series which we will be using throughout this tutorial. Let’s look at some examples of plotting a pandas series values as a histogram. The pandas series plot() function returns a matplotlib axes object to which you can add additional formatting. Here, s is the pandas series you want to plot. SQL-like merging/joining of DataFrame objects The join function Pivots and reshaping data Stacking and unstacking The stack() function The unstack(). The following is the syntax: # histogram using pandas series plot() To plot a histogram, pass 'hist' to the kind paramter. It plots a line chart of the series values by default but you can specify the type of chart to plot using the kind parameter. Python Pandas - Series, Series is a one-dimensional labeled array capable of holding data of any type. To plot a pandas series, you can use the pandas series plot() function.
