Is it possible to change the font size of the node ID when I zoom in on a figure generated by the biograph viewer in the Bioinformatics Toolbox 3.1 (R2008a)?

I have a large graph represented by a biograph object. When visualizing this graph with the VIEW function, the font size of the node IDs and labels were reduced to accommodate them within each node box. However, when I zoom into a region within the biograph figure, the node boxes change size but the text does not. I would like to be able to zoom in on a node and have the text increase in size proportional to the rest of the graph.

The ability to change the font size of the node ID when the ZOOM function is used is not available in the Bioinformatics Toolbox 3.1 (R2008a).

The biograph viewer displays node IDs and labels by creating MATLAB text objects at every node in the graph. The font size of these text objects is not influenced by the limits of the axes and therefore does not change when zooming into the axes.
