matplotlib - Why does the Seaborn color palette not work for Pandas bar plots? -

-

an online jupyter notebook demonstrating code , showing color differences at: https://anaconda.org/walter/pandas_seaborn_color/notebook

the colors wrong when make bar plots using pandas dataframe method. seaborn improves color palette of matplotlib. plots matplotlib automatically use new seaborn palette. however, bar plots pandas dataframes revert non-seaborn colors. behavior not consistent, because line plots pandas dataframes do use seaborn colors. makes plots appear in different styles, if use pandas plots.

how can plot using pandas methods while getting consistent seaborn color palette?

i'm running in python 2.7.11 using conda environment necessary packages code (pandas, matplotlib , seaborn).

import pandas pd import matplotlib.pyplot plt import seaborn sns  df = pd.dataframe({'y':[5,7,3,8]})  # matplotlib figure correctly uses seaborn color palette plt.figure() plt.bar(df.index, df['y']) plt.show()  # pandas bar plot reverts default matplotlib color palette df.plot(kind='bar') plt.show()  # pandas line plots correctly use seaborn color palette  df.plot() plt.show()

credit @mwaskom pointing sns.color_palette(). looking somehow missed hence original mess prop_cycle.

as workaround can set color hand. note how color keyword argument behaves differently if plotting 1 or several columns.

df = pd.dataframe({'x': [3, 6, 1, 2], 'y':[5, 7, 3, 8]})  df['y'].plot(kind='bar', color=sns.color_palette(n_colors=1))

one column plot

df.plot(kind='bar', color=sns.color_palette())

two columns plot

my original answer:

prop_cycle = plt.rcparams['axes.prop_cycle'] df['y'].plot(kind='bar', color=next(iter(prop_cycle))['color']) df.plot(kind='bar', color=[x['color'] x in prop_cycle])

i have order , ordersearch models. in order list (actionindex) gridview there filtering , sorting. on of columns in order order_total (sum of products in order). i need implement sum of order_total in gridview. if manually counting activedataprovider->getmodels() array_map spend 3 seconds 3000 orders (localhost). don't want miss time. i see 2 ways make faster: create cache every filter , update lifetime (horrible) the interesting can right in ordersearch->search() method $query method. don't understand how can pass in controller. example of code 2nd way: class ordersearch extends order { public $totalsum; public function search($params) { $query = order::find(); $dataprovider = new activedataprovider([ 'query' => $query, ]); $this->load($params); $this->totalsum = $query->sum('order_total'); // works fast return $dataprovider; } } after i...

Sass watch command compiles .scss files before full sftp upload -

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
