To insert a Gantt chart, click on the Insert Tab in the PowerPoint® menu, navigate to the empower charts section and click on the Gantt chart button.
You can now define the area in you want to insert the Gantt chart by clicking and drawing the cursor across the slide. This step can be interrupted by clicking Esc. If you wish to insert a Gantt chart directly into a placeholder on the slide, select the respective content or chart placeholder and click the Gantt chart button.
To edit a Gantt chart – either optically or its data – select the chart. The Action Bar will appear which allows you to make your adjustments.
To change the size of the Gantt chart at a later date, select the chart and the click and draw the endpoints to the desired size. Alternatively, you can alter the size via the native PowerPoint® function. To do so, select the chart and navigate to the Format tab in the PowerPoint® menu then change the chart’s height and width. Once you reduce the size of the Gantt chart you may receive a notification that the font size has been automatically adjusted. If this was not desired, you have the option to simply click on Undo changes.
