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);
}
////////////////////////////////////////////////////////////////////////////////////////////////////////////
