As a minimal scatter_matrix example to switch off axis ticks and rotate the labels, #May need to offset label when rotating to prevent overlap of figure #Hide all ticks plt.show() and similarly, you can adjust labels, resize, etc with any of the axis objects contained in the returned handle from scatter_matrix. This results in,
See difference: Or use numpy.searchsorted, but values of days has to be sorted:
The easiest way is to use to_datetime: It also offers a dayfirst argument for European times (but beware this isn’t strict). Here it is in action: You can pass a specific format:
This method is under pandas.plotting – docs and pandas.plotting.scatter_matrix:
You could merge and them multiply: Output
sort() was deprecated for DataFrames in favor of either: sort_values() to sort by column(s) sort_index() to sort by the index sort() was deprecated (but still available) in Pandas with release 0.17 (2015-10-09) with the introduction of sort_values() and sort_index(). It was removed from Pandas with release 0.20 (2017-05-05).
This expands on Paul’s answer. In Pandas, indexing a DataFrame returns a reference to the initial DataFrame. Thus, changing the subset will change the initial DataFrame. Thus, you’d want to use the copy if you want to make sure the initial DataFrame shouldn’t change. Consider the following code: You’ll get: In contrast, the following leaves … Read more
I’m not entirely sure what you want, and your last line of code does not help either, but anyway: “Chained” filtering is done by “chaining” the criteria in the boolean index. If you want to chain methods, you can add your own mask method and use that one.
My best guess relies in this part: It first says that myTempData[‘Actuals’] is a column of size len(MyActualData.index) containing only True values. Next, it replaces everything by another column of size len(MyExpectedData.index) (which I expect to be different) containing False values. You can first create a column of True values and, only then, replace False ones:
The rename method takes a dictionary for the index which applies to index values.You want to rename to index level’s name: A good way to think about this is that columns and index are the same type of object (Index or MultiIndex), and you can interchange the two via transpose. This is a little bit confusing since the index names … Read more
