Hi everybody !

I'm working on Odoo 12

I have a question with graph views. I want to show a weight evolution in a graph view with a line type.

My code is :

<record model="ir.ui.view" id="view_graph_consultations">
    <field name="name">consultations.graph</field>
    <field name="model">dt.consultation</field>
    <field name="arch" type="xml">
        <graph string="Consultations evolution" type="line">
            <field name="date" interval="day" type="col" />
            <field name="weight" type="measure" />
        </graph>
    </field>
</record>    

And the result is what i was expected, but the problem is that i don't want a date in my x axis if i havn't a weight for this date.

I can't post image so i hope my question is clear ^^

Thanks you :)
