Code: Select all
local font;
local Size=10;
function Prepare()   
font = core.host:execute("createFont", "Wingdings", Size, false, false);
end

function Update(period)
core.host:execute("drawLabel1", 1, source:date(period), core.CR_CHART, source[perice], core.CR_CHART, core.H_Center, core.V_Top, font, core.rgb(0, 255, 255), "\108");
end
 
function ReleaseInstance()
       core.host:execute("deleteFont", font);
end


You can use core.host:execute("drawLabel1" ... ).
