<div style="word-wrap:break-word">Sorry! I already have a script calculating the trend/month in each grid. So as I take the aave(trend) I get the trend of the domain I define. However, I'd like to calculate the derivative of this trend line, over time, not only show it in a plot. So if I just could extract the max and min value that would be fine, but if there is a command that could do the same, that would be even better.<div>
