python - Plotting Parallel Coordinates in pandas with different colours -

-

i have data frame this: 

    0   1   2   3   4   5   6   7   8   9   cluster 0   0.018420    0.003357    0.002626    -0.015603   -0.009005   -0.023671   -0.016316   0.066504    -0.039526   0.037820    1   0.017684    0.003434    -0.003338   -0.003904   -0.021871   -0.009454   -0.013772   -0.004610   -0.006150   -0.005746   2   0.018857    0.003987    0.001749    -0.019840   0.011184    -0.020451   0.082434    -0.008789   0.000449    0.005445    against 3   0.020454    0.026437    0.036899    0.027168    -0.018483   -0.001076   0.005831    -0.002117   -0.011288   0.007491    4   0.018006    0.005365    0.001298    -0.006953   0.017034    0.006931    0.000268    0.001615    0.016707    -0.017798   against  df.columns index([0, 1, 2, 3, 4, 5, 6, 7, 8, 9, u'cluster'], dtype='object')

the last column 'cluster' specifies whether observation belong "for" cluster or "against" cluster.

i want plot such observations "for" same coloured while "against" same colour. there 2740 obs, transparency in lines required give better visualisation.

i did following , plotting same colour red both classes when specifying colour option. 

parallel_coordinates(y_embed,'cluster',color=["r" if c=="for" else "g" c in y_embed.cluster])

where y_embed data frame.

if don't mention colour option plot 2 colours default. want put own colour option.

any advice?

the color argument list of colors 1 color each cluster, not 1 color each row. can make plot green 1 cluster , magenta other cluster this: 

parallel_coordinates(data,'cluster',color=['g','m'])

to make lines transparent can use rgba values colors. 

parallel_coordinates(data,'cluster',color=[[1,0,0,0.2],[0,1,0,0.9]])

here first set red , partially transparent , second green , opaque.

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
