Hi Jody,
If you already have the points in two lists, you can use the “recall_list()” function from the ti_system module to pull in the lists into your Python program.
Then to draw the lists, you can two options:
- draw_poly(xl,yl)
- Use a “for” loop to iterate through the lists and use: draw_line(xl[i],yl[i],xl[i+1],yl[i+1]).
With this method, you will have to be careful about your range() for the ‘for’ loop – it will need to end at len(array) - 1
The attached TNS file has two lists and a Python program that shows both options.
If you run the program as-is, it will plot in black, wait for you to press a key and then plot the same graph using the 2nd method in red.
Hope this makes sense.
Please let me know if you have any questions or comments.
Regards,
- Harshal
