thanks for help.

i understand the idea about making it to strings.

but i think i do it for the plotting panel only.

EJS keep hanging on me when i tried to change the field_old 1.0 to take the string.

2 times already.

appreciate the help, this idea i going to use it on the plotting panel to show the angle with a polygon.

my next design improvement :D

You should be able to use the same technique for the textString GUI element (to be added into the PlottingPanel).
Check out the EjsConsole, it will provide information about [b]run time error[/b] to know why the ejs was hanging.
