Hey Hive account@haejin, as someone who has followed your posts for a while, can I make a suggestion. Please add a graph...the graph should be the first one in a series of 3, keeping the two you already post. The only difference is the first graph would have no indicators or lines drawn. This will help me and others as students to make our own educated guess at what the lines should be. Then we can look at your graphs to see if we are in agreement or not. Does that sound like a good idea? Thanks!
