Hello,

I have a widget_button that calls a procedure "plot_function" :
row_base4 = widget_button(TLB, /align_left, value=' Plot
',event_pro='plot_function')

The proceduce is defined as:

pro plot_function, event
envi_plot_data, x,y
end

How to pass arguments, such as X and Y, to the procedure plot_function ?

Thanks

Francois.
