abrir como grafico como padrão

Hello, 
 
Thank you for your question.
 
A chart can be shown by default by specifying viewType in the options object, for example: 

var pivot = new Flexmonster({
   ...
   report: {
       ...
       options: {
          viewType: "charts",
          chart: {
            type: "column",
            showDataLabels: true
          }
       }
   }
});

Here is a JSFiddle example for illustration: https://jsfiddle.net/flexmonster/yaxwb3ps/
Please let us know if this helps.
 
Also, we would like to kindly ask to post future questions in English. 
Thank you in advance!
 
Kind regards, 
Vera
