i wondering if there way dispose of control in google charts? think solve problem.
so if have control table defined so...
stringfilter = new google.visualization.controlwrapper({ 'controltype': 'categoryfilter', 'containerid': 'control1', 'options': { 'filtercolumnlabel': 'columnnametofilteron' } }); if later on have checkboxes show/hide columns. using view.setcolumns(state) state array of columns display. issue after hiding column way end 2 errors , column not becoming hidden.
one or more participants failed draw() invalid column label: issue title view.setcolumns(state) works fine column without controltype defined it.
