Hi,

I'am trying to create a chart query but i'm not getting the results i want: this is how i did:
<ods-dataset-context context="mycontext" mycontext-dataset="mycontext"><ods-chart timescale="year"> <ods-chart-query context="mycontext" field-x="date" timescale="hour" series-breakdown="zone"> <ods-chart-serie expression-y="occupation" chart-type="line" function-y="AVG" color="range-Accent"> </ods-chart-serie> </ods-chart-query> </ods-chart></ods-dataset-context>

Thank you very much
