谷歌图表未显示其中一个图例文字，但数据已填充。我已将列名称作为＆＃34;错误＆＃34;对于未显示的图例。它对这种行为有什么影响吗？

答案 0 :(得分：0)
这里创建了表并添加了列......
var trendTable = new google.visualization.DataTable();
trendTable.addColumn('string', 'Execution Date'); // 0
trendTable.addColumn('number', 'PASSED'); // 1
trendTable.addColumn({ type: 'string', role: 'annotation' }); // 2
trendTable.addColumn({ type: 'string', role: 'tooltip' }); // 3
trendTable.addColumn('number', 'FAILED'); // 4
trendTable.addColumn({ type: 'string', role: 'annotation' }); // 5
trendTable.addColumn({ type: 'string', role: 'tooltip' }); // 6
trendTable.addColumn('number', 'ERRORS'); // 7
trendTable.addColumn({ type: 'string', role: 'annotation' });
trendTable.addColumn({ type: 'string', role: 'tooltip' });
trendTable.addColumn('number', 'SKIPPED');
trendTable.addColumn({ type: 'string', role: 'annotation' });
trendTable.addColumn({ type: 'string', role: 'tooltip' });
稍后，在绘制图表之前，将删除列标签，因此会显示空白的图例条目...
trendTable.setColumnLabel(7, ""); // <-- remove this
trendChart.setDataTable(trendTable);
trendChart.draw();
