Enumeration EScaleConst

constants for easier access to chart scales

PRIMARY and SECONDARY are contant ids that are identical in every chart; however, the left scale is optional and might not always exist

  const rightScale = controller.getObject({ objType: 'scale', id: BG.charts.Chart.EScale.PRIMARY }, chart);  // NEVER null
  const leftScale = controller.getObject({ objType: 'scale', id: BG.charts.Chart.EScale.SECONDARY }, chart); // could be null

Additional "invisible" scales have dynamically generated ids starting at SCREEN. This means that you even if there are 3 scales in a chart, the id SCREEN might not actually be in use. Instead you can use it to check if a given scale id is for an "invisible" scale

  const isInvisibleScale = (scale.get('id') >= BG.charts.Chart.EScale.SCREEN);
