A picture is worth a thousand words:

Probably one more is better:

You can read the installation instructions if you want to have it on your blog. It's a script to convert Blogger's Blog Archive into a bar chart using Column Chart of Google Visualization API. Since the API is interactive, you will still be able to click and to view the archive from the chart.

The only restriction is you must use dropdown menu style, I only write the parser for that, you can still choose one of Monthly, Weekly, and Daily. The chart will draw accordingly. The color is default to gray bars, but you can customize the chart.

I got this idea when I was reading this month's post count after I just finished something on GitHub. The GitHub's commits timeline chart gave me this inspiration.

My original idea was writing a Blogger Gadget, unfortunately, I saw no way to retrieve same data as Blog Archive receives. The only way is to process a list of published dates via JSON API with Partial Fields. It's not really a big deal, but for long-lasted blog, it may have thousands of posts. It's really not so efficient.

I decided to parse the dropdown menu of Blog Archive gadget, not perfect but better than previous way in my opinion. Later, I rewrote a bit and wrote a Blog Archive XML, so no dropdown menu will be rendered, which you probably only would see in a blink if you install this barchart'd code with parsing method.

The installation is really easy either your modify template or simply add two lines to an HTML/JavaScript gadget, that's all you need to do.

I put the code with BloggerGadgets.js, and moved the repository to GitHub, because the file hosting need. I wished I could keep the code on Bitbucket, but I couldn't, tried hg-git, but it hanged when I tried to push to gh-pages branch via hg bookmark.
