The help of the SetCtrlAttribute will tell you what the limits are for some
attributes such as ATTR_LABEL_TEXT

The help for ATTR_PLOT_LG_TEXT  states, "The length of this string cannot be greater than 30 bytes."  You can find this and the rest of the CVI help online by simply searching ni.com. 

According to this, the length of 30 characters is hardcoded into CVI. Does this help file answer your question?
