Go inside the project and tweak the values in the custom block called f(x) #custom blocks are just functions The program will plot the function for you. Tweak the xmin/xmax and ymin/ymax values if you want to zoom in or out Use the program on turbo mode if the 'blinking' annoys you. It will redraw super fast and remove the blinking effect.
