How to | Add Transparency to Plots
Transparency is useful in plots when you need an unobstructed view of multiple components of one plot, or simply want to lighten a single plot component against a white background. The Wolfram Language uses the graphics directive Opacity to apply transparency to graphics objects. Opacity can be used with most visualization functions.
Here is a 2D plot:
Use the PlotStyle option with Opacity to make the plot 70% transparent:
Here is a 3D plot:
Make the plot 60% transparent:
Add different transparency settings for plots of multiple functions:
Here is a 2D region determined by two inequalities:
Make the plot 50% transparent:
Use Opacity to see the inner parts of a plot:
Use the ContourStyle option of ContourPlot3D with Opacity:
You can also add transparency to graphics.
Make a 75% transparent disk:
Opacity can have values between 0 and 1, with 0 corresponding to perfect transparency:
Use Opacity with a color:
Opacity interacts well with other Wolfram Language functions:
