resample/interpolate time series with datetimeindex
I have two dataframes each containing one or more time series from the same time frame but sampled at different timestamps. I’d like to merge them into a single one resampled and interpolated with the index of the first. Here’s a sample of the first dataframe: And the second one: In this case the second one is more granular but
Pandas finding local max and min
I have a pandas data frame with two columns one is temperature the other is time. I would like to make third and fourth columns called min and max.

Remove ‘seconds’ and ‘minutes’ from a Pandas dataframe column
Given a dataframe like: I would like to remove the ‘minutes’ and ‘seconds’ information. The following (mostly stolen from: How to remove the ‘seconds’ of Pandas dataframe index?) works okay, but it feels strange to convert a datetime to a string then back to a datetime.

Plot elapsed time on x axis using date indexed time-series data
In my pandas dataframe, my time series data is indexed by absolute time (a date of format YYYY-MM-DD HH24:MI:SS.nnnnn): How can I plot this data such that the x-axis of my plots is an increasing value of some interval of seconds (e.g, “0 10 20 30 40 50”) relative to the timestamp of my first sample ? Do I need
ObsPy Plot Beachball in Time Series
I am trying to plot an ObsPy (or any python) seismic focal mechanism in time series. When using an integer/float series for x it works fine, but the time series fails here: The function xy2patch in the source code is trying to scale the time by a float value. Any ideas? Hack the source? Other packages? Thanks. Answer Found it.
