javascript - Google visualisation errors -


i have google vis datatable , dashboard (control filters, string control, datatable, charts). element bind.

so database json , send gviz api draw table, chart , control. when use contols filter data , if there no data string error google visualisation this:

one or more participants failed draw()×

table has no rows.×

and similar messages. in app ugly there way not showing it? if there no data not show error...

i try css option:

#google-visualization-errors-all-3 {    display:none; }

but not solution me.

is there other way, maybe in google visualusation api dashboard?

update:

          piechart.draw();         };       }          google.setonloadcallback(drawvisualization);// javascript document

this code, important part .ajac function, how can here integrate if row>0 show charts ???

i had same problem using google charts api. around had check number of rows made through filters. if it's >= 1, draw chart. else whatever need to; don't draw chart, display error, etc.
