Hi,
ok i have found another problem.. i use the "Map" Chart with a
chartWrapper and i build a filtered view like this(I use the latitude
longitude mode):
var filteredView ={columns : [0,1,2], rows :
dataTable.getFilteredRows([{column: 2, minValue: 100, maxValue: null}])};
so for example the minValue is 100, but 100 did not exists in the
DataTable. This is no problem by other charts but if the
dataTable.getFilteredRows() method did not find any results and i give
this view to my chartWrapper it throws an ugly error message. It looks like
this:
<https://lh5.googleusercontent.com/-c1ksluWoPu4/VAOUHMfNZnI/AAAAAAAAAAM/4wUY_iPR-eI/s1600/GeoMAPerror.PNG>
How can i solve this problem if my filter did not find a result ? Can i
display an empty chart or an chart with no markers ?
and the problem that "chartWrapper.getChart().clearChart();" is not working
with a "Map" Chart, still exists...
