It would be interesting to find out why the longer time programming the lower the chance that the respondent answered that question... I think it is because they already have a job??

@evaristoc, yeah, I'm also very curious about it - will dig into that asap

About the chart... I cannot really visualize the proportions per category, specially for the least represented category. Could you find a better representation?

Yeah, I see your point! Don't worry, right now all my visualizations are for acknowledge purpose only. I'm exploring the data and sharing some interesting facts with text & simple vizs.
But I need to add a legend for grey NA, that's totally true, but not sure how to do it in an easy way with ggplot. You said you love gplot, can you help me? :) Do you know how to add custom legend for stat_count or just add NA into legend?
Of course, I've tried to search for it, but didn't find any simple solution... R is so not user friendly!
Thanks!

@evaristoc lol, I've just discovered that 5 questions were asked only if respondent doesn't work as a software developer, yet. I will write to @erictleung to add that info to questionnaire.

NA is grey
So yeah, my yesterday's statement about "Coders with big experience have less job preferences"was wrong :(

@evaristoc, but still, tell me please how to do custom legend or just add NA into the legend, if you know.

@SamAI-Software great work with these charts! Yes - explore the data first, then convert to D3. I think these stacked bar charts are a good way to go for a lot of visualization, though they aren't as exciting as, say, a force-directed graph ;)
@evaristoc as always, thanks for the great weekly digest!

@SamAI-Software

  • about finding the 5 questions :+1: ! that is also the good thing about exploring the data :)
  • about just showing results: yeah. the work is still wonderful.
  • about NA: just a quick thinking... I would copy the column and substitute NA with another category instead ("if (value = NA) then (value = "NA")). Then I could have some control on that too...

@jacobborges
I am interested, although I might not be on pace for any other training at the moment... can you tell me why you are into multilinear algebra and where, how, etc is the training you want to follow?

("if (value = NA) then (value = "NA")) @evaristoc nice idea!

:+1: let me know if it works for you, anyway...

For now I just don't show NA's, but later on I might come back to that issue

About how many hours do you spend learning each week?

  • Almost half (47%) of coders with 5+ years of experience who already work as software developers still spend at least 10 hours each week learning programming.

Do we have something which looks at what strings @camperbot returns "nothing found" for on help/wiki/etc ?

@SamAI-Software Excellent, man! Few days and you are going to exhaust all the possible questions about what can be done with that dataset!! :) :)
But really: nice...
Advice for the last one? Easy: show the proportions and look for a way to report the n per category somewhere else? Perhaps in the sub-title of the figures...
Proportions instead of total counts for this one will allow cross-comparisons (a simple way to standardise the data...)

@SamAI-Software I was suggesting "conditional" proportions (I think it is x% | Time,SD?), not the simple ones.

Chapter 9. Modeling Infectious Disease with Cellular Automata sounds interesting. will be a while before i have a chance to read this though
evaristoc

May 16 2016 22:26
Models of spreading diseases by assuming kind of random modelling... similar to the "Game of Life" we are building here...
