R-Plot a Stored Graphic

Hello, I've a stored Pie-Chart: P=pie([1 2 3])

When I first use the Function, it shows me the Pie-Chart. And when I close it and type the whole Pie-Command again, it shows me the chart again. But I can't just type "P" and Matlab shows me the chart again. Is there any specific command to do this, or is it not just easy to do?

Hii,

MATLAB workspace variables will be deleted after exiting ,so you will not be able to access variable ‘P’. Moreover ‘P’ is a graphics array, so you can’t get pie chart from variable ‘P’. Instead you can save data for which you want pie chart in a variable (a=[1 2 3]),save it to .mat file using save. After reopening MATLAB you can load .mat file using load. Then use command pie(a),to get pie chart.

You can use below line of code for same:

p=[1 2 3]
save("variables.mat")

After initialising matlab:

load("variables.mat")
pie(p)
