All empower charts functions are accessed via the Home or Insert tab in the PowerPoint® menu. If you also use empower you have the possibility to use empower charts directly from either the Insert tab or the empower menu.
To insert a chart, click on empower chart and select one of the available chart types.
If you have previously selected a placeholder on your slide, empower charts will insert the selected chart directly into the selected placeholder. To edit the chart – either its appearance or data – simply select the chart. An action bar will appear above the chart which will allow you to make the desired changes.
