I have a graph which displays data from the database. An external application injects data into some of the database tables, I need to refresh it automatically so the graph should contains the latest inserted data, is there a way to do it using JavaScript or anything else ?

here is my view xml code :

<!-- rate graph views -->

<record model="ir.ui.view" id="id_view_tauxExtractSemoule">
    <field name="name">moulin.graph.view1</field>
    <field name="model">tdb_moulin</field>
    <field name="type">graph</field>
    <field name="arch" type="xml">
	<graph string="moulin" type="line" >
            <field name="num"/>
	    <field name="tauxExtractionSemoule"/>
	</graph>
    </field>
</record>


<!-- action extraction semoule-->

<record model="ir.actions.act_window" id="id_action_tauxExtractSemoule">
    <field name="name">Taux d'extraction de semoule</field>
    <field name="res_model">tdb_moulin</field>
    <field name="view_type">form</field>
    <field name="view_mode">graph,form,tree</field>
    <field name="help" type="html">
        <p class="oe_view_nocontent_create" Some text here for help
        </p>
    </field>
    <field name="view_id" ref="id_view_tauxExtractSemoule"/>
</record>

and then I declared menuitems and associated the action id to them
