The paper referenced does not have code for the macro.
The link in the paper to supposed source code is broken.
The note about the macro supposedly being included as an Autocall macro means that it may be part of a module I do not licensed.
As such, I do not know what the macro is actually calling for the display of the graph.
If the format applied to the y axis variable doesn't work we'll need some help, such as which module the macro is part of. If you can find the source of the macro on your computer then copy the code and paste it into a code box opened using the forum's {I} icon.
