I am using Plus Chart(pluscharts.com/demos/) library in my application. I use 3d pie chart in my application. It works fine but in some cases Pie is generated but not display as there is large amount of data only some part of pie chart is shown. What should I do that it render completely every time? Is there any attribute needs to set in chart json for auto resizing the pie? Can any one please help me? Thanks in advance. Please forgive me for my bad English.

Below is json for plus chart
var plusPiechart = new HeroCharts({
'chart': {
'type': '3dpie',
'chartcontainer': containerid,
'heading': '',
'width': 800,
'height': 500,
'originx': 0,
'originy': 0,

'overflow':'visible',
'legendposition': 'right',
'legendbox': false,
'startingangle': 135
},
'series': performanceArray1
})

What I have tried:

I have tried

'margin': 800,
