You see the parameterization of the box:

1. Selector type of Timeseries graph.
2. Column of the sentence with temporary value, in this case the day of invoice invoicedate.
3. Filter by combo of the column The_year and thus be able to filter the graph by years.
4. SQL statement to execute, in this case:

<select>
    <columns>
        YEAR(invoicedate)  <alias name='the_year'/>,
        invoice.invoicedate,
        SUM(invoice.total) <alias name='the_total' />
    </columns>
    <from table='invoice'/>    
    <group>1,2</group>
    <order>1,2</order>
</select>

* Starting from the table of invoices and grouping by year and day.

5. In the series the column ' the_total' is added with the numerical value, in this case the total sales per month and year.

In this type of graph the user can interact to filter part of their values.

• (1) Filter by combo, for each year returned in the main sentence.

• (2) By clicking on the zoom values, the graph will increase or decrease.

• (3) Imputing the date in the fields from - to.

• (4) The lower zone allows to be expanded or contracted and with lateral displacement to control the zoom of data.
