You can use the scatterfunction to plot a scatter plot between Volts Vs. Average current values.
Since scatter needs both the arguments to be vectors, you can convert average current values into a single vector before plotting.
You can refer the following code for example.
Volts = [10,20,30,40,50];
AC_1 = -10; AC_2 = 20; AC_3 = 25; AC_4 = -5; AC_5 = 30.5;
Average_Current = [AC_1, AC_2, AC_3, AC_4, AC_5];
The output will look as follows.
Hope this helps.
