Try this:
function matrix:bgcolor_cb(l, c)
-- play here
local green =0
local blue =0
local red =200
if c == 0 then
return iup.IGNORE -- title row, not used
end
if l == 0 then -- title column
return iup.IGNORE
end
return red, green, blue, iup.DEFAULT
end
Best,

What NetFlow Analyzer can do for you? Monitors network bandwidth and traffic
patterns at an interface-level. Reveals which users, apps, and protocols are
consuming the most bandwidth. Provides multi-vendor support for NetFlow,
J-Flow, sFlow and other flows. Make informed decisions using capacity planning
reports. http://sdm.link/zohomanageengine
