In this article, we will explore the following pandas visualization functions – bar plot, histogram, box plot, scatter plot, and pie chart. One limitation, for instance, is that we cannot plot both a histogram and the density of our data in the same plot. Histogram plots traditionally only need one dimension of data. Scatter plots are used to plot data points on horizontal and vertical axis in the attempt to show how much one variable is affected by another. IDL Python . The above plot represents 1000 data point in 10 bins. Here in the example, head() shows you the few rows and the full columns of the datasets which makes easier to see the available data and its components. Histogram grouped by categories in same plot.
