Animated Trajectory from a .csv file

[Ceren Guzelgun]

Hi everyone. 

I'm working on https://cloud.sagemath.com.

I have a csv file saved in a project, a file that has two columns of data. 

I want to animate these points like a trajectory. So far, I can only plot it normally as:

------

import csv

import sys

f = open('test.csv', 'rt')

xArr=[]

yArr=[]

line=f.readline()

while(line !=''): 

    xy=line.split(',')

    xArr.append(float(xy[0]))

    yArr.append(float(xy[1]))

    line=f.readline()

list_plot(zip(xArr,yArr))

------

And as a result ofcourse, I get my plot inanimate.

Is there anyway I can animate it point by point?

Thanks already.

Hello,

Start with that demo example given here http://combinat.sagemath.org/doc/reference/plotting/sage/plot/animate.html

sines = [plot(c*sin(x), (-2*pi,2*pi), color=Color(c,0,0), ymin=-1,ymax=1) for c in sxrange(0,1,.2)]

a = animate(sines)

a.show()

I believe you are not so far .... add some lines more to your code

Unfortunately, the demo example(s) weren't helpful.

More info, and suggestions would be much aprreciated.
