In the Notebook capture of release gantt chart, the release title is shown with a bar indicating the span of each phase or milestone. If you hover over the bar or marker, the date is shown in the pop-up tooltips. When these pages are printed or screenshots taken, the dates are not indicated anywhere other than through the ruler on top. We need the dates for each phase/milestone to be indicated in front of its name on the left hand side of the chart.

This can be achieved via the Reports Timeline page. You can create a custom chart which shows the dates in the first column, alongside additional bars for your visualization.
