(PHP version) Area chart show value 0 for null value. (Fixed by my own)

[sospixs]

Sometimes we want chat to show null value not zero in some reason.
In case of year on year compare (Jan-Dec) ex. 2013 vs 2014 sales performance accumulate.

Series 2013 will have all month jan-dec , But 2014 is not because current month is nov so dec will be null value not zero. If null value has covert to be zero the chart will show in the wrong meaning.

Code edit : ChartComponent.php
The original function code

  public function addSeries ($id, $name="", $seriesData = array(), $opts = array())
    {
        if(is_array($id)) {
            if(is_string($name)) {
                $name = array();
            }
            else {
                $name = is_array($name) ? $name : array();
            }
            $this->setOption("showLegendFlag", false);
            $this->addSeries ("series_0", "", $id, $name);
            return;
        }

    $seriesData = array_map('floatval', $seriesData);  
        $this->provide('series');
        $opts['seriesName'] = $name;
        $this->props->addItemToList('chart.series', $id, $opts);
        $this->data->addColumn($id, $seriesData);
    }

The new function code edit

     public function addSeries ($id, $name="", $seriesData = array(), $opts = array())
    {
        if(is_array($id)) {
            if(is_string($name)) {
                $name = array();
            }
            else {
                $name = is_array($name) ? $name : array();
            }
            $this->setOption("showLegendFlag", false);
            $this->addSeries ("series_0", "", $id, $name);
            return;
        }
// Add function to passing null value
            $func = function($value) {
                if (is_null($value))
                    return null;
                else return $value+0;
            };

        $seriesData = array_map( $func, $seriesData);  // Call function  
        $this->provide('series');
        $opts['seriesName'] = $name;
        $this->props->addItemToList('chart.series', $id, $opts);
        $this->data->addColumn($id, $seriesData);
    }
