By default, the PictureHeightNode property is -1. Use the PictureHeightNode property to specify a different height to display all pictures in all nodes. Use the Picture property to specify the node's picture. The PictureWidthNode and PictureHeightNode properties of the ChartView object handles the size of the displayed pictures for all the nodes. The PictureAspectRatioNode property specifies the aspect ratio for the node's picture based on the original width or height. The PictureWidth and PictureHeight properties handles the size of displayed picture for specified node.

The size of the picture being shown in the node is computed as follow:

• if the PictureWidth and/or PictureHeight property is specified, it indicates the width or the height of the picture being shown in the node.
• if the PictureWidthNode and/or PictureHeightNode properties of the ChartView object is specified, it indicates the width or the height of the picture being shown in the node.
• If none of these is specified, the node displays the picture using its size.

In any case, the size of the picture is also influenced by the the aspect ratio for the node's picture as it is specified by PictureAspectRatio or PictureAspectRatioNode property while any of these is not exAspectRatioNone.

The following screen shot shows the root's picture resized, while the other nodes display the pictures using their original size.
