    Author’s reply » As many of you know, I have been working on a market model for a while now... this is a test graphic from that work. I wanted to see how a graphic of this size displays... I can see it fine on my Mac... how about those of you on Windows? If everyone can see it, I can standardize the size of the charts to match this one.


    The chart shows the yearly average of a 20 day standard deviation from 1950 - 2012. The 20 day standard deviation is what is used in the Bollinger band calculation. As you can see from the chart, the average yearly variation started to exponentially increase in the 80s.


    This is a problem because this version of the model needs an average variation figure. If I included data all the way back to the 50s, the average variation figure would be lowered because of the long tail on the left of the distribution. The model does have some theory behind it, so I used that theory to help me determine the cut-off value.


    I added some key financial deregulation points on to the chart to add in the interpretation of my primary metric...

    The full image renders perfectly. The thumbnail is a bit blurry, but that may be a problem on our end. How did you upload the image?

    Author’s reply » Hi Eli
    Thanks very much for looking at it.


    The original graphic was created in PowerPoint. I grabbed an image with a snapshot tool on the Mac. That's what gave me the .tiff file.


    I used a Mac graphics tool called Graphics Converter to convert it into a JPEG format. I used the upload button in SA's instablog creation work area to upload the image.


    I created the file on a large screen Mac. I am now on a portable Mac and it looks fine without clicking on it. It does get easer to read when it's clicked (enlarged).


    Is there an optimal graphics image side and format for SA? I think I can convert it into any kind of graphics image with the Graphics Converter program.

    Good grief! I didn't see this before. Anyway,


    On my Linux box it looks fine. When I right click and open in new tab the ctrl-+ and ctrl- keys do what's expected. This with Firefox browser.

    If I hadn't been giving a link to ScotlandGuy in the APC, I wouldn't have seen it. But he mentioned an interest in bioscience, so I linked to your index of blogs. While there I rummaged a bit and there it was!


    Don't know how I missed it before.
