Can you explain what you are trying to do? For example,

Do you want to put a PNG with alpha-transparency into the graph? (Easy. It just works.)
Do you want to use alpha-transparency in a script to draw transparent lines? (Also easy. Use the transparent() function.)
Do you want a static picture behind the data? (Also easy, unless you mean #4. Just move the picture to the back so it draws first.)
Do you want to save the graph to a PNG and have the white background be transparent? (Not easy. JMP does have a preference for the report background, but the graph always forces a white rectangle. @XanGregg I'd wish for a transparent background color option.)

The difference between 3 and 4 is huge: 3 places the data points over an image that will always be in the same place with respect to the data. 4 places the data points "on a sheet of glass"; you can then slide the glass over different images. You might want 4 if you are building a web page with a scrolling effect. Otherwise 3 should address most needs. (Even with 3, if JMP is running you can move or change the background image using JSL or the mouse.)

If you really need the last one, there are ~~two~~ one possible workarounds:

Save as SVG, then manually (or with a script you write) edit the SVG text to remove the white background.
probably won't work.

我是想到达这个目的:

先用性别为分类、分别以男性、女性各自作出气泡图(不用的形态作图)

然后将这两个图重叠的效果

谢谢专家!

这样不懂得如何改变不同性别的图形形态

There are two ways to do that. I think GraphBuilder and RowState markers would be the easiest. First set the markers for the groups:

Circle and Triangle markers

Set up GraphBuilder

You can change the jitter option if you don't want the overlapping symbols dodging each other.

Or you can do it with BubblePlot the way you were trying by using Edit->Copy Frame Content and Edit->Paste Frame Content:

Use Draw and Shape to make the hollow shapes.

Copy the content from one...

...paste to the other.

I do not like the copy-paste choice because it would be an extra step, hard to script, leaves an extra graph on the screen, and the pasted points in the destination graph are NOT selectable. I think the GraphBuilder choice is much better.

非常感谢专家的帮助!

如果能得到这些操作的JSL就更好了。

谢谢！

You can script the Bubble Plot copy/paste frame contents. I'd still use Graph Builder.

Scripting Index

请教怎样用脚本来实现这个标签？谢谢！

我搜索了、没有实现。

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
dt << Color or Mark by Column( :sex, Marker Theme( "hollow" ) );
Graph Builder(
	Size( 532, 447 ),
	Show Control Panel( 0 ),
	Variables( X( :age ), Y( :height ), Size( :weight ) ),
	Elements( Points( X, Y, Legend( 4 ) ) )
);

looks good!

I like the jitter effect for this example. You might not want it for some data.

我明白了、谢谢！

And there is an extra legend entry. You can remove it:

Red triangle->Legend Settings...
