Can anyone guide me how to code the arrow line in different direction. wa and wl is positive the rectangle will be on top of the x-axis. Below example shown if wl is negative and wa is positive. The code below shown how i code the rectangle shape. x1 is the varaible to state where to start at x axis. e1 is the length of the shape, wa1 and wl1 is the height. wsign to determine the height wa1 or wl1 should display at negative side or positive side. if (Math.abs(wl1) > Math.abs(wa1)) { y_scale = (load_y0 - 40) / (double) Math.abs(wl1); } else { y_scale = (load_y0 - 40) / (double) Math.abs(wa1); } g.drawLine((int) ((double) x0 + x1 * x_scale), (int) (load_y), (int) ((double) x0 + x1 * x_scale), (int) (load_y + (wa1 * y_scale) * -1)); g.drawLine((int) ((double) x0 + (x1 + e1) * x_scale), (int) (load_y), (int) ((double) x0 + (x1 + e1) * x_scale), (int) (load_y + (wl1 * y_scale) * -1)); g.drawLine((int) ((double) x0 + x1 * x_scale), (int) (load_y + (wa1 * y_scale * -1)), (int) ((double) x0 + (x1 + e1) * x_scale), (int) (load_y + (wl1 * y_scale) * -1));
