How to select multiple plots:
In graph window, use Shift + click to select multiple plots
In Object Manager, use Shift + click to select a range of plots, use Ctrl + click to select only those clicked plots
After selection, use toolbar or mini toolbar to edit them. Note: mini toolbar only shows if all selected plots share the same plot type.
In Object Manager, user can also right click for show/hide, remove, etc.
In Object Manager, after selecting multiple plots in same layer, user can press Alt key and drag to change plot order. This way, the plots will draw on top of bar.
