Example

// Simple
figure.add({
  name: 'eqn',
  make: 'equation',
  elements: {
    bar: { symbol: 'bar', side: 'top' },
  },
  forms: {
    1: { bar: ['a', 'bar', 'top'] },
  },
});
figure.elements._eqn.showForm('1');

Example

// Some different bar examples
figure.add({
  name: 'eqn',
  make: 'equation',
  elements: {
    hBar: { symbol: 'bar', side: 'top' },
    vBar: { symbol: 'bar', side: 'right' },
    hArrow: { symbol: 'arrow', direction: 'right' },
  },
  forms: {
    // Array equation
    1: { bar: [['a', 'b'], 'hBar', 'top'] },
    // Object definition
    2: {
      bar: {
        content: ['a', 'b'],
        symbol: 'hBar',
        side: 'bottom',
      },
    },
    // Additional options for layout
    3: {
      bar: {
        content: ['a', 'b'],
        symbol: 'vBar',
        side: 'right',
        overhang: 0.1,
      },
    },
    // Vector arrow
    4: {
      bar: {
        content: ['a', 'b'],
        symbol: 'hArrow',
        side: 'top',
      },
    },
  },
  formSeries: ['1', '2', '3', '4']
});
const eqn = figure.elements._eqn;
eqn.onClick = () => eqn.nextForm();
eqn.setTouchable();
eqn.showForm('1');
