Description Joachim Magera 2022-05-31 11:37:19 EDT 
Chart1.SaveToMetafile(Filename)

and 

   Chart1.SaveToMetafileEnh(Filename) 

does produce simple PNG file
Comment 1 yeray alonso 2022-09-23 05:35:37 EDT 
I've done an example, exporting a simple chart to both formats:

  SaveToMetafile('example.wmf');
  SaveToMetafileEnh('example.emf');

When I open them with IrfanView, and I open their "Information", it tells me they are "Windows Metafile (Aldus)" and "Windows Metafile (Enhanced)".

Also, if I rename those files to .png, when I try to open them in IrfanView, it alerts me they are metafiles with the wrong extension and suggests me to correct it.

I'm closing this as "not a bug" because I can't reproduce it.
I'll be happy to reopen it I can reproduce it.

Sorry, I was testing it in VCL.
I could reproduce with the same code in FMX so I've reopened it.
Comment 3 yeray alonso 2022-09-23 06:19:53 EDT 
VCL's export to metafile uses Vcl.Graphics.TMetafile from Embarcadero which isn't ported to FMX.

To make TeeCreateMetafile to work on FMX (and SaveToMetafile, SaveToMetafileEnh and SaveToMetafileRect) we made our own TMetafile class inheriting Fmx.Graphics.TBitmap.

I'm closing this as "not a bug" because that was intended.
If Embarcadero ever adds an Fmx.Graphics.TMetafile, then we'll be able to rewrite this.
