Hi,

I'm using ZK Charts 2.0.0.1 & ZK 8.0.0-RC and I want to export a chart. There is a button for exporting, which is working if you click it manually.

Export Button

But I want to trigger the button and export a PNG with java code. I got multiple charts and I want to create a "export all" button.

So it is possible to export a chart with java code?

Hi,

it is possible to get JSON from your chart series (and options etc.)

for (int i = 0; i < chart.getSeriesSize(); i++) {
    series += chart.getSeries(i).toJSONString() + ",";
}

With this data you can send a POST Request to an export server. To get a PDF you have to set the return type parameter to 'application/pdf'
