How to change the row height of gantt chart by dragging the mouse

Hello, @Victor0405 !
Unfortunately there is no easy solution how to change the row height by dragging the mouse.
Currently there is no way to give one row a different height than others, it’s a limitation of the library that can’t be bypassed without changes in source codes.
You can change the row height only setting row_height property.
