tollbox. Visual studio design IDE tab called "toolbox" has categorised iems in it eg "common controls" , "data", "general", "'containers", "crystal reports", "printing". Usually there is a group called Chartfx.
this gets done for you during the chartfx setup. Why it dissappears I don't know.
Any way I have uninstalled the poduct and reinstalled it.
The toolbox items have been fixed so no problem anymore. I can add charts succesfully
Now I have an ongoing problem. In run time the chart does not display the same as in design time. eg Multiple panels are missing data, bars and lines get mixed up.
