How to set error bars to back as default

Question

Hello,

For viewing purposes, I would like to hide the negative error bars for my bar chart. I have accomplished this using the Graph Builder "customize" options but I would like to know if this can be set to default.

Any time that I make a change to a variable or open the script the negative error bar shows up, so the formatting does not hold in the JSL.

Thanks!

Hi, bio_grad.

I have a trick to get what you want. However, I am reluctant in sending a reply, because as a statistician, it is an understatement to say that I am *not* a fan of these plots. I find them much less informative than a boxplot or density plot for many observations or a raw data plot when there are few observations. That said, on several occasions I have sent to JMP my wish to be able to set graph element order. You can set it for a custom graphics script, or line segments, but not other elements (at least that I know of).

The trick is to get the bar graph drawn last. A simple way to do that is to create the bars again. Note the script adds the element bars with error bars, then it adds them again, so they are last.  A redo will keep the order.

So this should help, but I recommend you consider other graphs.  I know these are popular with some university profs, so you might not have a choice. Good Luck.
