I am getting real-time data as shonw in the figure attached. The red and yellow bars are real-time data and are moving higher/lower dynamically according the the magnitude of my data. I want to display this figure as a seasaw. Basically, the left side represents the red bar, and the right side represents the yellow bar. When the red bar has a higher value than the yellow bar, the seasaw should tilt to the left side. The angle of the tilt should reflect the difference between the red and yellow bar. Is there any way to achieve this?

pick nominal x coordinates for the endpoints of the see-saw. Create a line that has those as the x coordinates and has the "current" (or possibly time-averaged) values of left and right as the y coordinates. As you get new data, update the YData of the line with the appropriate values. You do not need to do anything explicit about the angle: the angle will naturally exist as the y coordinates change.
