I am very new to Tableau and still trying to get the hang of it, but could not find the answer to a problem I am having. I am working with a graph that has 6 different trend lines on it. However, I need to show the significance of only two of them. Is there a way for me to change the style or size of only two trend lines, while leaving the other four as they are?
If this is not possible, does anybody know the best way to show significance on certain trendlines?
