How can I get the objectid of a chart

[Anonymous]

I want to just display a chart if it's objectid = variable

eg

vDisplayChart='CH12'

then in CH12 using conditional show

if(myObjectID=$(vDisplayChart),1,0)

where myObjectID is the ID of chart.

I know I could hardcode as in

if($(vDisplayChart)='CH12',1,0)

but would be far neater/easier for copying charts if the formula could pickup the chart's own object name.
