| 1178 | ---------- |
| 1179 | series : series |
| 1180 | The series instance to be converted. |
| 1181 | domain : {None, array_like}, optional |
| 1182 | If given, the array must be of the form ``[beg, end]``, where |
| 1183 | ``beg`` and ``end`` are the endpoints of the domain. If None is |
| 1184 | given then the class domain is used. The default is None. |
| 1185 | window : {None, array_like}, optional |
| 1186 | If given, the resulting array must be if the form |
| 1187 | ``[beg, end]``, where ``beg`` and ``end`` are the endpoints of |
| 1188 | the window. If None is given then the class window is used. The |
| 1189 | default is None. |

| 1192 | ------- |
| 1193 | new_series : series |
| 1194 | A series of the same kind as the calling class and equal to |
| 1195 | `series` when evaluated. |
