python - matplotlib radar plot min values -


i started matplotlib radar example values below min values disappear. have gist here.

the result looks like

this

as can see in gist, values d , e in series both 3 don't show @ all.

there scaling going on. in order find out problem started original values , removed 1 one.

when removed 1 whole series scale shrink. here example (removing factor 5) , scale in [0,0.2] range shrinks.

from

this

to

series

i don't care scaling values @ 3 score show up.

many thanks

actually, values d , e in series show up, although plotted in center of plot. because limits of "y-axis" autoscaled.

if want have fixed "minimum radius", can put ax.set_ylim(bottom=0) in for-loop.

if want minimum radius number relative lowest plotted value, can include ax.set_ylim(np.asarray(data.values()).flatten().min() - margin) in for-loop, margin distance lowest plotted value center of plot.

with fixed center @ radius 0 (added markers better show points plotted):

by setting margin = 1, , using relative y-limits, output:

php - regexp cyrillic filename not matches -

i take list of files php glob(."*.pdf") . files have cyrillic names. example: ООО «Рога и копыта» then load company names database , try find them in file names: preg_match("/$firm_name/ui", $file_name, $match); i have problem: firms if $firm_name visually similar $file_name , preg_match says there no match. mb_detect_encoding both variables return utf-8. there problem in file name, or maybe there encoding or something, can not understand, ask help. upd: $file_name='ООО «Рога и копыта»'; preg_match("/... .Рога и копыта./ui", $file_name, $match); as result, ОО «Рога и копыта» , 1 О missing

c# - OpenXML hanging while writing elements -

Image
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 ...
