I'm measuring the height of the water and I want to show it on the graph. When the level falls below a certain value, I want the macro to assign an average value to the graph. In the graph, the y axis is level_b. However, when the second condition is provided in this way, the whole graphic line disappears from the screen. while(1) level_a = (level - 457) * 0.6546 if(level < 473.0) level_b = 100 else level_b = level_a endif endwhile
