Only a very small number of figure objects can be made transparent using the 'alpha' scale (RGB Alpha). Since such transparent colors cannot be emulated by RGB values alone, workarounds exist for figure objects such as lines:
Is there a workaround to make text transparent ?

Use getframe to get the contents of the figure. Then create the text with a white background and getframe again to get a copy of the written text. Then add the RGB values of the two images weighted by the alpha value. Finally the result is displayed by the image command.
The same method is applied in FEX: uibutton.
