Fullscreen function for zoomcharts can be enabled by adding extra item under the toolbar, the code is shown as below:
testChart = new PieChart({toolbar: { extraItems: ["fullscreen"] }});
However, there is a bug when the pie chart under fullscreen view. Drilldown the pie chart repeatedly and rapidly will causing the pie chart change back to the normal view again automatically. Is there anything can do in order to solve this problem? Thank you.
The version of zoomCharts that I used is 1.8.4 (same for ver 1.8.1).
