Plot discrete points on a graph TI-BASIC -

i've been delving ti-basic programming language on ti-89 titanium appears online documentation scarce, i'm kind of stumbling around in dark while trying learn syntax. i've worked through basic concepts presented in guidebook on programming, seem far complete/descriptive.

for starters, how may plot discrete points 1 may in statistics (i.e. value @ every integer on x-axis)?

so far see may append generated points end of list [note "->" mean "sto"]

newlist(5)->total disp total 

displays list {0. 0. 0. 0. 0.}. now, if write loop iterate on list like

for i,.2,1.,.2  i->total[i] 

i should have list {.2 .4 .6 .8 1.}. here problem arises: want plot these points on graph screen against integers on x-axis, starting @ x=1. how do this? specifically, want plot points

(1., .2), (2., .4), (3., .6), (4., .8), (5., 1.)

the issue attempt attempted store values @ .2, .4, .6, , .8 slots in list, not exist. fix problem, do:

:for i, 1, 5, 1 :i*0.2 -> total[i] 

this should produce list. plot this, use plot1 (or plot2 or plot3) command plot this:

:plot1(scatter, {1, 2, 3, 4, 5}, total, .) 

the first param type of plot, second list of x values (im not sure if did work, may have create list of x values , input that). third y values, , final mark on graph. know there 3 available in catalog on ti-84 family calculators. i'm not sure ti-89, symbols available on ti-84 • @ point, + @ point, , a(n) ○ around point. luck project.
