  1. Users are often interested in creating pareto charts using conditions they've created in Seeq sorted by a particular capsule property. The chart below was created using the Histogram tool in Seeq Workbench. For more information on how to create Histograms that look like this, check out this article on creating and using capsule properties. Often times users would like to see the histogram above, but with the bars sorted from largest to smallest in a traditional pareto chart. Users can easily create paretos from Seeq conditions using Seeq Data Lab. A preview of the chart that we can create is: The full Jupyter Notebook documentation of this workflow (including output) can be found in the attached pdf file. If you're unable to download the PDF, the code snippets below can be run in Seeq Data Lab to produce the chart above. #Import relevant libraries from seeq import spy import pandas as pd import numpy as np import matplotlib import matplotlib.pyplot as plt Log in to the SPY module if running locally using spy.login, or skip this step if running Seeq Data Lab. #Search for your condition that has capsule properties using spy.search #Use the 'scoped to' argument to search for items only in a particular workbook.
