What is the dashboard graph widget can used for on the qweb template, like project overview timesheet plan from sale_timesheet module or etc. ?
I try this but widget does not work
<div class="row">
<t t-name="MyGraph">
<t-esc="graph_data" t-options="{'widget': 'dashboard_graph' }" t-attf-graph_type="'line'"/>
</t>
</div>
Why the widget can not rendered on the qweb ?
