python - Add x and y labels to a pandas plot -


suppose have following code plots simple using pandas:

import pandas pd values = [[1,2], [2,5]] df2 = pd.dataframe(values, columns=['type a', 'type b'], index=['index 1','index 2']) df2.plot(lw=2,colormap='jet',marker='.',markersize=10,title='video streaming dropout category')

output

how set x , y-labels while preserving ability use specific colormaps? noticed plot() wrapper pandas dataframes doesn't take parameters specific that.

the df.plot() function returns matplotlib.axes.axessubplot object. can set labels on object.

in [4]: ax = df2.plot(lw=2,colormap='jet',marker='.',markersize=10,title='video streaming dropout category')  in [6]: ax.set_xlabel("x label") out[6]: <matplotlib.text.text @ 0x10e0af2d0>  in [7]: ax.set_ylabel("y label") out[7]: <matplotlib.text.text @ 0x10e0ba1d0>

enter image description here

or, more succinctly: ax.set(xlabel="x label", ylabel="y label").

alternatively, index x-axis label automatically set index name, if has one. df2.index.name = 'x label' work too.

c# - OpenXML hanging while writing elements -

i have program pulls data database, caches file , exports data multiple formats (excel, excel 2003, csv). i'm using openxml sdk 2.0 excel work. these export processes run in parallel (using parallel.foreach ), , amount of data can pretty large - e.g. csvs 800mb. during these larger exports, i've noticed writing of xml documents hang. instance, if have 8 exporting in parallel, @ point "pause". hang around same point: //this.writer openxmlwriter created worksheetpart. this.writer.writeelement(new cell() { cellvalue = new cellvalue(value), datatype = cellvalues.string }); when happens, pause debugger (vs2013 in case) , notice threads blocking around same portion of code - bit deeper in openxml sdk - stem call openxmlwriter.writeelement . i dug through source using justdecompile didn't find answers. appears there intermediary stream in use writing isolated storage , is, reason, blocking. underlying stream each of these filestream . here screenshot ...
