On the horizontal scale, a length of 1 is the size of one 'pixel' (more about that later). The vertical scale usually does not matter from the programmer's perspective, because we will be normalizing the samples in a certain way that will automatically scale it correctly. Once a filter is normalized, the area under its curve will be 1. Resampling time series data with pandas. In this post, we'll be going through an example of resampling time series data using pandas. We're going to be tracking a self-driving car at 15 minute periods over a year and creating weekly and yearly summaries. There are two similar ways to describe this shape in numbers. For example, for a 6000x4000 pixel image, the ratio of the two sides is 6:4, which we reduce to say 3:2. This is also the ratio of 3/2 = 1.5, or 1.5:1 when one side is compared as 'one'. Same thing, and we may encounter it either way (typically we say it as 3:2, but we compute with 1.5).
Returns a Resample object for performing resampling operations.
Handles both downsampling and upsampling. The resampleddimension must be a datetime-like coordinate. If any intervalscontain no values from the original object, they will be giventhe value NaN.
indexer (
{dim:freq}, optional) – Mapping from the dimension name to resample frequency 1. Thedimension must be datetime-like.skipna (
bool, optional) – Whether to skip missing values when aggregating in downsampling.closed (
{'left','right'}, optional) – Side of each interval to treat as closed.label (
{'left','right'}, optional) – Side of each interval to use for labeling.base (
int, optional) – For frequencies that evenly subdivide 1 day, the 'origin' of theaggregated intervals. For example, for '24H' frequency, base couldrange from 0 through 23.loffset (
timedeltaorstr, optional) – Offset used to adjust the resampled time labels. Some pandas dateoffset strings are supported.keep_attrs (
bool, optional) – If True, the object's attributes (attrs) will be copied fromthe original object to the new one. If False (default), the newobject will be returned without attributes.restore_coord_dims (
bool, optional) – If True, also restore the dimension order of multi-dimensionalcoordinates. Darkwood 1 0.**indexer_kwargs (
{dim:freq}) – The keyword arguments form ofindexer.One of indexer or indexer_kwargs must be provided.
resampled – This object resampled.

Which side of bin interval is closed. The default is ‘left'for all frequency offsets except for ‘M', ‘A', ‘Q', ‘BM',‘BA', ‘BQ', and ‘W' which all have a default of ‘right'.
Which bin edge label to label bucket with. The default is ‘left'for all frequency offsets except for ‘M', ‘A', ‘Q', ‘BM',‘BA', ‘BQ', and ‘W' which all have a default of ‘right'.
For PeriodIndex only, controls whether to use the start orend of rule.
Pass ‘timestamp' to convert the resulting index to aDateTimeIndex or ‘period' to convert it to a PeriodIndex.By default the input representation is retained.
Adjust the resampled time labels.
Deprecated since version 1.1.0: You should add the loffset to the df.index after the resample.See below.
For frequencies that evenly subdivide 1 day, the 'origin' of theaggregated intervals. For example, for ‘5min' frequency, base couldrange from 0 through 4. Defaults to 0.
Deprecated since version 1.1.0: The new arguments that you should use are ‘offset' or ‘origin'. Simlab composer 9 2 23 kjv.
For a DataFrame, column to use instead of index for resampling.Column must be datetime-like.
For a MultiIndex, level (name or number) to use forresampling. level must be datetime-like.

‘epoch': origin is 1970-01-01
‘start': origin is the first value of the timeseries
‘start_day': origin is the first day at midnight of the timeseries
An offset timedelta added to the origin.

Examples
Start by creating a series with 9 one minute timestamps.
Downsample the series into 3 minute bins and sum the valuesof the timestamps falling into a bin.
Downsample the series into 3 minute bins as above, but label eachbin using the right edge instead of the left. Please note that thevalue in the bucket used as the label is not included in the bucket,which it labels. For example, in the original series thebucket 2000-01-0100:03:00 contains the value 3, but the summedvalue in the resampled bucket with the label 2000-01-0100:03:00does not include 3 (if it did, the summed value would be 6, not 3).To include this value close the right side of the bin interval asillustrated in the example below this one.
Downsample the series into 3 minute bins as above, but close the rightside of the bin interval.
Upsample the series into 30 second bins.
Upsample the series into 30 second bins and fill the NaNvalues using the pad method.
Upsample the series into 30 second bins and fill theNaN values using the bfill method.

For a Series with a PeriodIndex, the keyword convention can beused to control whether to use the start or end of rule.
Resample a year by quarter using ‘start' convention. Values areassigned to the first quarter of the period.
Resample quarters by month using ‘end' convention. Values areassigned to the last month of the period.
For DataFrame objects, the keyword on can be used to specify thecolumn instead of the index for resampling.
For a DataFrame with MultiIndex, the keyword level can be used tospecify on which level the resampling needs to take place. https://coolpfiles399.weebly.com/free-yellow-magic-orchestra-bgm-zip.html.
