Hi, very new in ROS, so now i am trying to calibrate my Lidar. I seen that in MATLAB we can plot the Data retrieved from the laserScan, MATLAB is not opensource so is there any way to get data and make the plot?

I am not 100% sure to know what you mean by "plot" data from the laser. Do you want to draw on 2D the points or to create a single plot for each beam of the laser (X axis = time, Y axis = range) ?
