How to draw Bar charts on NXT with Robotc
Posted: 27 Apr 2013, 19:47
Hello,
I am working on a code where i have to collect sensor readings for (light, sound, sonar) every second and display a graph at the end with min and max values.
I also have to display total readings which was easy. I have put together all the code except for the graph part. I would really appreciate if anyone would help me out on this.
Here my code so far :
