MacPlot: Font, Size, Style or Color Doesn‘t Match the Screen
Both MacDraw II and Claris CAD allow you to specify a different font, size, style and color for each character in a text block. MacPlot, however, is unable to vary character style within a text object and the entire block will acquire the characteristics of the last character in the block.
This information was provided by Claris Corporation on 16 March 1998, and incorporated into Apple Computer's Tech Info Library.
You must create a separate text object whenever you want to change the style of your plotted text.
Note: This isn't an issue with MacProject II which doesn't allow you to use utilize various formats.
