The chart toolbar permits quick access to the most important chart functionalities and is highly customizable.
Left click on the toolbar options and select Add / Remove commands to select the icons you wish to be displayed within the toolbar.
The chart toolbar is space-friendly; it only becomes visible when the mouse cursor is located within the chart.
If too many icons are added into the chart toolbar and not all can be shown within the chart, you can select the Hidden Commands menu item to view the remaining icons.
