I have two ganttbars in a gantt chart using pgfgantt. I want to show that "at this point, the work from here will influence the other part of the project" by making a link that goes from the bottom of a ganttbar to the top of another one at a given time point. Is there a way to do this?
Thank you for your help!!
A toy that one may have is the following:
\begin{ganttchart}[y unit chart=.7cm]{1}{12}
\gantttitle{2020}{12}
\gantttitlelist{1,...,12}{1}
\ganttbar{Project 1}{1}{9}
\ganttbar{Project 2}{4}{12}
\end{ganttchart}
I want to show that at Month 5, Project 1 will give lead to information for Project 2. Is there a link that makes this possible?
