GWT Highcharts - Multiple Axes

A seguir está um exemplo de um gráfico com vários eixos.

Já vimos a configuração usada para desenhar um gráfico no capítulo Highcharts Configuration Syntax .

Um exemplo de gráfico de combinação com vários eixos é fornecido abaixo.

Configurações

Vamos agora ver as configurações / etapas adicionais realizadas.

YAxis

Obtenha vários yAxis usando o método chart.getYAxis (index).

chart.getYAxis(0);  
chart.getYAxis(1);
