Graph dispatch zoom in action

One-line summary [问题简述]

I am unable to programmatically zoom into rendered graph. As the page is loaded, graph is loaded. I need to zoom in particular part of the graph. Don’t know how.

Version & Environment [版本及环境]

• ECharts version [ECharts 版本]: 4.1.0
• Browser version [浏览器类型和版本]: Chrome 69, but probably doesn’t matter
• OS Version [操作系统类型和版本]: Mac OS Mojave but probably doesn’t matter

Expected behaviour [期望结果]

There should be available method for zoom in…

ECharts option [ECharts配置项]

option = {
            title: {
                text: ''
            },
            tooltip: {},
            toolbox: {},
            animationDurationUpdate: 1500,
            animationEasingUpdate: 'quinticInOut',
            series: [{
//                focusNodeAdjacency: true,
                type: 'graph',
                layout: 'none',
                symbolSize: 10,
                symbolKeepAspec: true,
                roam: true,
                dataZoom: {
                    type: 'absolute'
                },
                nodeScaleRatio: 0.6,
//                scaleLimit: {
//                    min: 0,
//                    max: 10,
//                },
                label: {
                    show: true,
                    position: 'bottom',
                    color: '#0066b2',
                    fontSize: 1,
                    distance: 0.1
                },
                edgeSymbol: ['circle', 'arrow'],
                edgeSymbolSize: [4, 10],
                edgeLabel: {
                    normal: {
                        textStyle: {
                            fontSize: 20
                        }
                    }
                },
                data: myChartData,
                links: myChartLinks
            }]
        }

@narenderv7 You can get the zoom and center from chart.getOption().series[0] and save it. Then, when you want to restore, set it with chart.setOption. It should work. The document seems to be out of date, I will update it soon.
