OpenGL Line Chart

[JohnnyIce]

hi

i´ve already posted similar question on this site.....

but i have a .txt file with numbers from microcontroller......

the format is:

23
43
12
23

(all numbers in first "row")

i can read the information from the file, but can´t seem to make a line chart
only "pie chart" and "bar chart"....

is there anyone here that has made line chart with OpenGL


thanx
Johnny

Hope it suggests some ideas

glBegin(GL_LINE_STRIP);
glVertex2i(10, 23);
glVertex2i(20, 43);
glVertex2i(30, 12);
glVertex2i(40, 23);
glEnd();

obviously you must setup an ortho projection.
