Show HN: Charts for Hacker News Polls
- BenSchaechter 15y agoOr, people could just run their polls using http://gopollgo.com http://gopollgo.com and get a heck of a lot more analytics. Here's an example: http://gopollgo.com/what-do-you-think-of-gopollgo http://gopollgo.com/what-do-you-think-of-gopollgo Disclaimer: I'm the founder -- but this is really what our site shines with.
- SudarshanP 15y agoAwesome! It would be nice to have prev and next button for the chart detail page. Even better if u could add a swipe for mobile devices
- awaz 15y agoThat's a good idea for frontpage and best polls.
- zacharydanger 15y agoI hear JGC's Pie Chart Challenge calling... http://blog.jgc.org/2011/09/pie-chart-challenge.html http://blog.jgc.org/2011/09/pie-chart-challenge.html
- Tichy 15y agoI must admit I don't fully get his argument. Is there research into the perception of pie charts, or is it just an assumption that people are bad at judging areas and angles?
- zacharydanger 15y agohttp://en.wikipedia.org/wiki/Pie_chart#Use.2C_effectiveness_and_visual_perception http://en.wikipedia.org/wiki/Pie_chart#Use.2C_effectiveness_... Looks like research has been done. Yes.
- rcfox 15y agoI'm not a web developer, so maybe I'm misremembering, but wasn't there something in HTTP that let you check the last time a page changed? Scraping the poll pages every 10 minutes seems like it would cause a lot of unnecessary requests to HN. Also, you probably consider any poll that's not on the first few pages of the 'news' or 'newest' sections to be complete. Sure, they might change, but they're not going to change by enough to affect your graphs.
- sbashyal 15y agoThe only way to 'listen' to page changes is to scrape it unless the web-page provides a notification service. Since that is not the case with HN, I had to resort to scrapes.
- mooism2 15y agoIf-Modified-Since? You still have to issue the http request.
- icebraining 15y agoThere are ETags too, but they suffer from the same problem (and usually dynamic pages don't serve them).
- jrberger 15y agogreat job, Shishir. are the legend/poll options in the same order as shown on the original poll? i ask because the colors are a wee bit difficult to differentiate. feature request: link to the original page.
- crntaylor 15y agoThis is cool, but you really should have used bar charts rather than pie charts. Humans are really good at comparing lengths, and terrible at comparing areas. As an example, your chart of which database systems HNers use is almost meaningless to me - it conveys less information than staring at the raw data does. If you were able to rewrite to use bar charts instead, this would be a kick-ass tool.
- gordonbowman 15y agoThis is great. I think it would be helpful to add the percentages here too. Perhaps in the key so as not to clutter?
- hmigneron 15y agoThis is cool. The results of the first poll I looked at surprised me and I wanted to read the comments, so I think it would be useful to have a link to the actual poll (on HN) because I had to google it. Another small thing is that the "HN Charts" in the nav bar doesn't really behave as expected. For example, on that page : http://hnlike.com/hncharts/chart/?id=3298905 http://hnlike.com/hncharts/chart/?id=3298905 the link doesn't do anything. On other pages it brings you back to the home page.
