Related to Appian Charts: I'm using columnchartfiled with category and stack

Related to Appian Charts: I'm using columnchartfiled with category and stacking="NORMAL". How can I show total count above on each category.
My code is:
=load(
with(
local!categories: if(isnull(local!subData),{},union(
local!subData.category, cast(typeof(local!subData.category), {}))),
local!series: rule!columnChartSeries(
data: local!subData,
categoryField: "category",
labelField: "label",
datapointField: "datapoint"
),
a!columnChartField(
categories: local!categories,
series: local!series,
stacking: "NORMAL",
showDataLabels: true,
showLegend: true
)
)
)

Many Thanks in Advance....
