calculating average 7 Months ago Karma: 0
Hello! Thank you for this great joomla component!

I have one question: if all options in my poll are numbers, how do I calculate and display average result below results commonly displayed? I understand it has to be done in pollxtresult.class.php but I am not so good php coder.

Thank you very much

Hi,

the average is already calculated, because it's needed for the rating functionality (of course that only works properly for numbers) you just have to include to the results display... find the following lines in the file you mentioned:
Code:

if ($this->conf->sh_abs) $ret .= " ".$count;
if ($this->conf->sh_abs && $this->conf->sh_perc) $ret.= " ("; 
if ($r->data->type == "7") 
$ret .= $rdes;
else 
         if ($this->conf->sh_perc) $ret .= " ".$percVal."%";
if ($this->conf->sh_abs && $this->conf->sh_perc) $ret.= ")"; 

These lines are responsible for displaying (depending on the settings) something like "x (y%)". You could now add e.g.:
Code:

$ret .= $avg;

This is not really beautiful, but it should work (and I guess you can beautify it yourself?)
regards,
Oli

Ok I need average of all the votes, if I put $avg where you say it gets displayed after each of the questions. Can you maybe think of quick function that will calculate it and display it maybe?

Thank you
