python - Plotting GroupBy Object in Pandas -

-

i have dataframe various parameters (continuous time-series data) , other columns filter out various conditions; these made of 1 when condition true , nan when condition false.

if plot parameter , plot again in gate, can do:

df.parameter.plot() df.groupby('filter_column').parameter.plot(style='bo')

this example works fine, if want plot using line (style='b-' example) joins groups of filtered data line

a work-around create intermediate series, or multiply 2 columns within matplotlib call:

series = df.parameter * df.filter_column series.plot(style='b-')  plt.plot(df.parameter * df.filter_column,'b-')

i'm not fan of type of plot statement or creating intermediate columns. useful have direct groupby line plot deal nas in same way series.

does have more elegant workarounds this?

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
