Reply To: How to update values in line chart from MySQL DB

[Vishwas R]

@kodian,

CanvasJS supports multi-series charts as demonstrated in the previously shared sample. In order to render just one line (single dataseries), you need to pass just one dataseries in the chart-options as shown below.

$.each((data), function(key, value){
	chart.options.data[0].dataPoints.push({label: value[0], y: parseInt(value[1])});
});

Please take a look at this updated sample project for working code. Also refer to PHP Gallery for more set of examples along with source-code.

If you are still facing issue, can you kindly share sample project over Google-Drive or Onedrive along with sample database and brief us further so that we can understand your issue better & help you out?
