-Chapter 2 - Filtering data
-===========================
-
-In the previous chapter, you learned how to read and print data that is a
-bit raw. Now, try to select a few columns and handle them properly.
-
-Start with these two columns: Time (time) and Magnitude (mag). After getting
-the information from these columns, filter and adapt the data. Try formatting
-the date to Qt types.
-
-There is not much to do for the Magnitude column, as it's just a floating point
-number. You could take special care to check if the data is correct. This could
-be done by filtering the data that follows the condition, "magnitude > 0", to
-avoid faulty data or unexpected behavior.
-
-The Date column provides data in UTC format (for example,
-2018-12-11T21:14:44.682Z), so you could easily map it to a QDateTime object
-defining the structure of the string. Additionally, you can adapt the time
-based on the timezone you are in, using QTimeZone.
-
-The following script filters and formats the CSV data as described earlier:
-
-.. literalinclude:: datavisualize2/main.py
- :language: python
- :linenos:
- :lines: 40-
-
-Now that you have a tuple of QDateTime and float data, try improving the
-output further. That's what you'll learn in the following chapters.
