Neither a personal attack nor a critique of your skills and experience were intended. Your post described how you explored this data and mentioned that the scatter plots were not the best way. I added the "why," included the comment that "... the graphic below appeared in a recent blog post ..." and forgot to add the appropriate link. By the way, my reasoning for using a bar chart rather than a trendline: the underlying data was a collection of responses to separate surveys. Since we have to assume that different people responded to each survey, I did not want to imply that the opinion of the same group of people has changed over time. Maybe over a virtual beer we can discuss whether I am splitting hairs and whether the samples were representative of the population :) Andy:

When you create a blog post that refers to a graphic that someone else created, you should link back to their post, not save the graphic as if it's your own. Sorry, one other thing.

I argued in my post that the scatter plat was not the best way to represent the data. I also then posted the time trends like you recommend as well. I like the comments you add to your chart, however, I would have used a line chart instead of a column chart. It makes the trend much easier to see. Just a question, were you suggesting that I do not have the appropriate experience and skills? It sure comes off that way. I see you used my scatter plot.
