Here's the code, I tried using some other examples that use 'moment' from the forum and the same issue arises, but anyway:
<h3>Weekly Heat Transfer</h3>
<div class="row hidden-xs">
<div class="col-sm-12 text-center extraPadding chart-holder">
<ma-now update-interval="1 HOURS" output="theTimeNow"></ma-now>
<ma-get-point-value point-xid="DP_672608" point="myPoint3"></ma-get-point-value>
<ma-point-values point="myPoint3" values="point3Values"
from="theTimeNow | moment:'startOf':'day'|moment:'subtract':7:'days'"
to="theTimeNow" rollup="SUM" rollup-interval="1 DAYS">
</ma-point-values>
<ma-get-point-value point-xid="DP_284166" point="myPoint7"></ma-get-point-value>
<ma-point-values point="myPoint7" values="point7Values" latest="8">
</ma-point-values>
<ma-serial-chart style="height: 300px; width: 100%"
series-1-values="point3Values"
series-1-point="myPoint3"
series-1-color="purple"
series-1-type="column"
series-3-values="point7Values"
series-3-point="myPoint7"
series-3-axis="right"
series-3-type="column"
series-3-color="green"
options="{
valueAxes:[
{title:'kJ', axisColor:'black', color:'black'},
{title:'Outside Temp (°C)', axisColor:'green', color:'green'}
]
}">
</ma-serial-chart>
