zoom function on date not working continious vs discrete

[Karl Venter]

Hi All

I am having problems with zoom funtion in haxis

I have an array of data from PHP to Json to chart

i would like to zoom the h axis but suspect my data is not continious

The data points are taken at a specific time say 12:02:01 and next at say 12:02:59

so I have an array -- first point is time , them solar power then used power etc

I dont now how to change my 1st value (haxis value) so that the zoom function will work  

my chart var

///////////////////////////////////////////////////////////////////////////////////////////////////

fo var options = {

          crosshair: { orientation: 'both' },

          title: 'SOLAR POWER <?php echo ($new_date); ?>',

//           hAxis: { title: 'TIME', titleTextStyle: {color: 'red'},},

          hAxis: {title: 'TIME',  titleTextStyle: {color: '#333'},

                   slantedText:true, slantedTextAngle:80,

                        minValue: 0,    maxValue: 24, ticks: [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23]},

          vAxis: {title: 'POWER', minValue: 0},

           explorer: {

            actions: ['dragToZoom', 'rightClickToReset'],

            axis: 'horizontal',}

};

//////////////////////////////////////////////////////////////////////////////////////////////////////////

my php array generator

 

for ($x = 0; $x <= (count($points)); $x+=1) {

$ar1 = array(date("H:i",strtotime(substr($points[$x][1],0,10))),intval($points[$x][$select1]),intval($points[$x][$select2]),intval($points[$x][$select3]),intval($points[$x][$select4]));

array_push($chartData1,$ar1);

}
