Is there a way of displaying User Data on analog OSD through LUA?

ArduPilot Lua Scripting

Hi,

I am just starting with Lua scripts, and I wonder whether there is a way of displaying some info on OSD screen through some Lua command? I was not able to find an answer.

I am looking for something like print at X,Y, textZ.

For instance, in the following script, instead of sending message to GCS, I would like to display the message on OSD, is there a way of doing it?

In OSD, there is “MESSAGE” field, but I believe it does not reflect the message sent to GCS, or I amm wrong?

function update ()
local roll=ahrs:get_roll()
local rolldeg=math.deg (roll)
local ch12=rc:get_pwm(12)
local ch11=rc:get_pwm(11)

ch12L=0
if (ch12<1400) 
   then
       ch12L=-1
   end
if (ch12>1600) 
   then

       ch12L=1
    end
Pk=0
if (prevch12L~=ch12L)
   then     
      Pk=ch12L
      gcs:send_text(2, Pk)
      local Roll_P= param:get('ATC_RAT_RLL_P')
      Roll_P=Roll_P+Pk*0.01
      gcs:send_text(2, Roll_P) 
      param:set_and_save ('ATC_RAT_RLL_P',Roll_P)                       
    end

prevch12L=ch12L        
 
return update, 10

end

return update()
