Hello!

I would like to to have a simple Pie Chart. Let's say three pieces. x=[ 0.5 0.2 0.3] and plot this a a Pie Chart pie(x) gives my a nice chart. But when I store the Chart in a Variable y=pie(x) this gives ma also a Pie Chart but just typing "y" just shows:

y =

1×6 graphics array:

Graphics Graphics Graphics Graphics Graphics Graphics

So is there any command to re-plot the Graphic just by typing the varaibale in where it's stored?

You would help me very much!

MATLAB graphics objects cannot be saved as variable by using their handles. Once the figure closes, the handle becomes invalid. To save and recreate a figure, you need to save it as a .fig file. See savefig(): https://www.mathworks.com/help/releases/R2020a/matlab/ref/savefig.html
