Transparent Behavior of Image(Icons) annotation on XY Graph is not working

[atul_ghumade]

Hello Everyone,
I hope you all are doing well!

I'm trying to plot the Audiogram using XY Graph.

The icon annotations which I'm trying to plot on the XY Graph are actually Transparent(PNG format) in nature. 

When I'm trying to plot the same icons on the XY Graph, the icons are not plotting as PNG/Transparent background image. The icons are plotting with the weird white background.  
I want to plot the icons with the actual behavior of the image.

Please find the attached code. "Main Code.vi" is the Test Code.

You are using very ancient outdated code from around LabVIEW 6

Once you use the modern version, things will be transparent:

On a side note, while labVIEW only support drawing up to 24bit colors, The "read png" function does some magic here and creates a mask gleaned from the alpha channel.

@altenbach
Thanks for the help.
I tried the approach you shared but now the icons are not plotting on the XY Graph. It will be great help if you will share the modified code.

See if this works for you ...

I'm using @altenbach the code you shared. 
Icons are plotting on the upper left corner of XY graph.

Looks like I broke something... It definitely worked initially.... I'll check....

See if this works for you...

(Yes, it can be cleaned up. I currently left you coordinate manipulations as is)

See cleaned up code below...

Here's how that could look like for code clarity.
