Hi,
I am new to any of this area and trying to get a gauge chart i.e., updated
dynamically with latest entry on my database. I have a php script file
which can return the latest single plain float value like "30.25". I have a
html file with gauge chart code & want to get thechart updated with that
value every 5 sec but struck at following.
The working code with random value is like this
*setInterval(function() {*
* var flow = 40.65 + Math.round(60 * Math.random());*
* data.setValue(0, 1, flow);*
* chart.draw(data, options);*
* }, 5000);*
But when i try to get the variable from php file its not working like
following.
*setInterval(function() {*
* var flow = $.ajax({url: 'Gauge.php', dataType: 'text', async:
false}).responseText;*
* data.setValue(0, 1, flow);*
* chart.draw(data, options);*
* }, 5000);*
Please help me to correct the code. Thank you!
