Hi Mic,
You can use a macro as a mapper. In this case, the macro expects as input a
subgts containing the sliding windows ticks.
You can use this macro:
<%
'gts' STORE
$gts SIZE 2 <
<% [ 0.0 ] %>
<%
$gts 0 ATINDEX 4 GET 'a' STORE
$gts 1 ATINDEX 4 GET 'b' STORE
[ $b $a - $a / 100.0 * ]
%>
IFTE
%>
'mapper' STORE
This macro returns 0.0% if it's the first tick, or the increasing percent
if the sliding window has 2 values.
Here's a link with your
example: https://snapshot.senx.io/0005a145839e2b66-0-0-1a3b631c6d0b8b11
