Why shp theme doesn???t have ???Chart??? for demonstration after use the Dissolve Tool?

[NataliaNovoselova]

Hi,
I???ve noticed that after use the Dissolve tool (from Data Management tools) on a point shp theme ??? the result new point theme hasn???t opportunity for demonstration as ???Charts???.
The initial theme has this opportunity (in the "Properties ??? Symbology" it has Features, Categories, Quantities, Charts, Multiple Attributes).
But after dissolving the result theme (that also has some numerical fields) doesn???t have ???Charts??? opportunity.

Is it an error or I did something wrong? Is it possible to show  theme after Dissolve tool as a charts?

I saw  the result theme has in �??Shape�?� column �?? Geometry type �??Multipoint�?�.  The initial theme has Geometry type �??Point�?�
Is Geometry type �??Multipoint�?� could be a reason of absence the Chart opportunity? But how it�??s possible to obtain this opportunity for this kind of theme?
