Example

// Simple
figure.add({
  name: 'eqn',
  make: 'equation',
  forms: {
    1: { int: ['int', 'x dx', 'a', 'b'] },
  },
});
figure.elements._eqn.showForm('1');

Example

// Example showing different integral options
figure.add({
  name: 'eqn',
  make: 'equation',
  elements: {
    i: { symbol: 'int' },
    // ic: { symbol: 'int', num: 1, type: 'line' },
  },

  forms: {
    // Root object form
    1: {
      int: {

    // Root array form
    2: { int: ['i', ['x', '  ', '+', ' ', '_1', ' ', 'dx'], 'a', 'b'] },
    // Indefinite tripple integral
    3: { int: ['i', ['x', '  ', '+', ' ', '_1', ' ', 'dx']] },
    // Custom spacing
