Want to understand the date progress display on gantt chart

[Pooja Kewaliya]

I have installed a new plugin in JIRA i.e. team board pro with that while using that app on gantt chart i get the default fields of start date and end date. which can be pulled either from the jira project list of input it manually. But in gantt chart if i want to show a chart having multiple date comparison how can that be done. Also we tried to add new columns and manually update those dates but it seems to auto delete on updating.  Can you please try to help me with this feature please.

Hi @Pooja Kewaliya , I am unfamiliar with an addon by that name and do not find in the Atlassian Marketplace. If you are inquiring about the Gantt chart presented by the addon I recommend reaching out to the vendor for support if possible.
