I want to write values to two separate cvs files at the same. When I use "file:write()" to specify the value that I write to the file, how do I specify which file it should be on?

I need to change the size of the numbers in x and y axis(for example: time numbers in the x axis). I was able to change the line width by changing the Lua code script in the "graph_customization". What line should I change in this file to change the size of axis value numbers?
Thank you

Hi

Is there a way to change the line width of the graph? The default line width of the graphs are too small once I add them to my report.

Thanks

I need to export a variable (real time data values for that variable) to matlab. Is there a way to do this?

I added a graph to monitor real time velocity of my robot. It works fine as long as the simulation runs, but as soon as the simulation stops the graph disappears. I want to use that graph for my report. Is there a way to keep the graph once the simulation is stopped or a way o save that graph??
Thanks

Where do I write this code? Inside sysCall_actuation function?

Ant it is a differential car so I would only need the rotational acceleration about z axis

I'm new to Coppeliasim. Can you provide a sample code or something so I can get an idea on how to do that? Thanks

I am trying to find the acceleration (translational and rotational) of an object real time. I can find the velocity of the object using the get sim.getVelocity but then how do I get the acceleration? Is there a way to take the derivative of the velocity?

Hi! I'm building a two wheel differential robot that can be controlled with a joystick, and I plan to incoperate a PID controller for it. How do I implement a PID controller in coppeliasim?
