When the overall size of a chart is modified, Interactive Reporting attempts to redraw chart components using the object’s font size. If it is not feasible to redraw the component in the space available, the font size is reduced by one point, and another drawing is attempted. This process is repeated until the component can fit within the boundaries defined for it, or until a minimum font size is reached.
You specify the minimum font size on the “General” tab of Chart Properties. The default value for the minimum font size is 8.
The components which are modifiable by the minimum font size are:
When the component is first reduced, it continues to show the original font size and not the user defined font size. If the minimum font size is reached for the supported components and it is still too large to fit with obstructing or being obstructed, then the item is removed from display.
When Smart Scaling is used in conjunction with Auto Resize, changes to the Chart size are limited to all those methods which do not involve the movement of the chart border.
If you select the handles of the chart border and reposition them as the method to resize the Chart when Smart Scaling and Auto Resize are enabled, Auto Resize is automatically disabled. The Smart Scaling property remains enabled.
