Why I can't plot x = years , y = GDP

Answer 1

[Walter Roberson]

GDP.("YEARS")

retrieves the field Years from the GDP object, and displays the result (because you have no semi-colon on the line)

x=("YEARS")

assigns the string "YEARS" to x. This has nothing to do with GDP.("YEARS")

Perhaps you want

x = GDP.("YEARS");
y = GDP.("GDP");
plot(x, y)
