echarts柱状图定制化某条柱子&滚动条从左、右起始

人狠话不多，直接上代码：

var data1 = ['800', '1200', '1000', '840', '1320', '960', '750','800', '900', '1000', 
			'1200', '1102', '1003', '1014','1015', '856', '917', '818', '919', '920',
			'821', '822', '923', '924','825', '926', '827', '828', '929', '830',
			'1031', '1232', '1133', '1034','935', '1036', '937', '1138', '1099', '1040',
			'941', '1042', '1043', '1044','1045', '1046', '1047', '1248', '1149', '1150',
			'951', '952', '1053', '854','1055', '956', '857', '1058'];
			
var seriesData = [];
for (var i = 0; i < data1.length; i++) {
	var itemStyle = {};
	if (i > data1.length - 2) {
	    itemStyle = {
					normal: {
						//柱形图圆角，初始化效果
						barBorderRadius:[0, 5, 5, 0],
					    color: new echarts.graphic.LinearGradient(0, 0, 1, 0, [{
