Inkscape 42”x36” Scientific Poster w/ SVG source (Caffeine’s Impact on Sleep)

This is a followup post to Caffeine’s Impact on Sleep, Inkscape A0 Scientific Poster draft

Finished my 42”x36” poster today (turns out 2.671, my Measurement and Instrumentation class, didn’t want A0). I saw some awesome horizontal and vertical designs Tuesday, and now I have this super-cluttered and not very aesthetically pleasing poster *sigh* Oh well. I liked my draft version better for its simplicity and think I have too much text on this final version.

Larger size PNG image available on dropbox,

!! PDF version available (large file, ~10Mb), as well as SVG source!!

 
Again, thanks to Alexander Erlich for the Inkscape template
Also, thanks to netalloy for the coffee cup vector
And thanks to OnlyPositive for the picture of the sleepy cat.
Google Docs
Spreadsheet here. I calculated averages and stddevs with =AVERAGE( ) and =STDEV( ) respectively, and turned formatted time (e.g. 07:30:00) into decimal hours (e.g. 7.50) (also applied Format > Number > Two decimals) using the formula =INT(F4)*24+HOUR(F4)+MINUTE(F4)/60

Matlab
Here is the matlab code I used. It’s very messy and I don’t actually understand what it means. In fact, I had to do post-processing of the Matlab > Export Setup > Rendering, Resolution = 300 > Export > figureN.png in the GIMP prior to dropping it in Inkscape to get the images I wanted.

figure 
caffeine4=[0 0 0 0 0 0 0 0];
sleep4=[6.95 10.87 9.75 7.52 10.95 9.43 8.75 10.23];
day=[25 26 27 28 29 30 31 32];
[AX,H1,H2] = plotyy(day,sleep4,day,caffeine4,'plot');

title('Phase 4: Daily Hours Slept and Caffeine Intake');
xlabel('Date (in April)');
%xlim([26 13]);
set(gca,'XTick',25:1:32);
%set(gca,'box','off');

set(get(AX(1),'Ylabel'),'String','Amount Slept Daily (hrs)'); 
set(get(AX(2),'Ylabel'),'String','Daily Caffeine Intake (mg)') ;
axis(AX(1),[25 32 0 11]);
axis(AX(2),[25 32 0 700]);
set(AX(1),'YLim',[0 11], 'YTick',0:1:11, 'box','off');
set(AX(2),'YLim',[0 700],'YTick',0:100:700,'box','off', 'box','off');

set(H1,'LineWidth',3,...
                'MarkerSize',7,...
    'LineStyle','-',...
    'Marker', 'o',...
    'MarkerEdgeColor', 'none',...
    'MarkerFaceColor', 'b');
set(H2,'LineWidth',3,...
                'MarkerSize',7,...
    'LineStyle','-',...
    'Marker', 'o',...
    'MarkerEdgeColor', 'none',...
    'MarkerFaceColor', 'g');

Above code resulted in this graph:

This data was actually 25 April to 2 May, but instead of learning about timeseries in MATLAB, I just cheated and stuck “April / May” in the xlabel and used 31 and 32 to not break my code. I planned to post-process in gimp to turn “31 32” into “1 2” but forgot to do so.

For phase 3, I couldn’t figure how to get rid of the 20.5 and 21.5 tick marks when I expanded to graphs to reasonable size, so I did post-processing in GIMP. Here are the two images I smushed together into the third:
+=

Misc. other tricks too lazy to document fully:
Using “shift-J” in Vim to turn newlines (ctrl-click-drag to get a column of values from google doc separated by newlines) into spaces, which Matlab uses to delimit vector data.

Making Instagram-like effect with kitten in top-left corner via kitten > right-click Add layer mask > (1) Gradient tool white-to-back, radial, click-drag from center to slightly past edges of images. This transparency-ed a large part of the cat face so (2) Ellipse select most of cat face, Gradient tool white-to-light-gray, radial, click-drag from center to edge of ellipse.

Inkscape, Filter effect > Make arrowheads match color to the lines. (If you decide to change the color of the arrowheads).

Caffeine’s Impact on Sleep, Inkscape A0 Scientific Poster draft

This post is continued at Inkscape 42”x36” Scientific Poster w/ SVG source (Caffeine’s Impact on Sleep)

Finished my draft poster for 2.671 Measurement and Instrumentation (required communications course for MechE undergrads). Basically, we are given free reign to design and collect data from our own experiment, and we have to present in a Poster Session at the end of the semester (I present next Thursday).

Well, I’m abysmally behind in this class but catching up, and I made this fluffy poster Thursday night – Friday morning. (Fluffy, as in not much content and no math). What follows is an overview of the tools I used, and at the end my poster / my Inkscape svg source file.

My Inkscape file is based on the wonderful Inkscape template I found online. I found it aesthetically pleasing compared to the default 2.671 template. (If you search for “2.671” on Google you’ll find some posters other classmates made using the default template).

Actually here’s Eli’s poster, which shows the default powerpoint template scheme if not the exact template:

MedHelp Visualization

My sleep patterns on MedHelp: medhelp.org/user_trackers/show/1150087 (all data off by one day, e.g. medhelp 5/4 = real life 5/3)

Data was manually entered. See poster below for what weeks correspond to what levels of caffeine.

this is the MedHelp user interface. GUI is a bit confusing, I like how Fitbit below has a “previous or same day” input option, maybe would have avoided putting all my data in off by one day.

See Actigraphy to understand why I can wear my fitbit on my non-dominant hand during sleep and get a rough idea of my sleep quality (how many times I almost woke up / was in light sleep mode).

Scientific Poster in Inkscape

Finally, I made a poster in the wonderful open-source free program Inkscape. More importantly, I used a template I found online.

I also used kuler to pick a color scheme and writer to help me write what I wanted to put on the poster, esp. since Inkscape started responding really slowly to my typing text so it was much faster to type it elsewhere and ctrl-c ctrl-v into the Inkscape text box. And GIMP to clean images I’d found online (two for fitbit) and I found the coffee cup on openclipart . The images sources aren’t cited yet, I had a crunch deadline for the draft poster and just turned it in anyway.

Here’s a preview of  my draft poster (and a perhaps helpful flowchart of things): entirely based on the example poster I found online. Thanks a bunch to airlich.

appendix

for reference, my research braindump from earlier in the semester:
http://nouyang.blogspot.com/2012/04/tools-for-scientific-posters-braindump.html

raw fitbit data

And then some current research on getting “raw data from fitbit”
http://blog.brianhouse.net/post/6877602920/an-activity-heatmap-from-fitbit-data

However, prior to the release of the Fitbit API, the developer Eric Blue published a hack in perl that scrapes data from your Fitbit profile page — turns out that the Flash charts they display are powered by an XML feed with significantly more resolution than what is offered via the API. Based on this discovery, I wrote a python script that pulls the granular data.

Yea, the Fitbit premium export of data just looks like:

Sleep
Date Minutes Asleep Minutes Awake Number of Awakenings Time in Bed
######## 0 0 0 0
######## 0 0 0 0
5/1/2012 0 0 0 0
5/2/2012 0 0 0 0
5/3/2012 136 22 16 190
5/4/2012 123 32 16 270
5/5/2012 0 0 0 0

which isn’t terribly useful to me. So yay more chances to practice coding skills. =^__^=
