| 6 | +This example showcases different linestyles copying those of Tikz/PGF. |
| 7 | +Linestyle can be provided as simple as *solid* , *dotted* or *dashed*. |
| 8 | +Moreover, the dashing of the line can be controlled by a dash tuple |
| 9 | +such as (offset, (on_off_seq)) as mentioned in `.Line2D.set_linestyle`. |
| 10 | +For e.g., ``(0, (3, 10, 1, 15))`` means 3pt-line,10pt-space,1pt-line,15pt-space |
| 11 | +with no offset. |
| 12 | +
|
| 13 | +*Note*: The dash style can also be configured via `.Line2D.set_dashes` |
| 14 | +as shown in :doc:`/gallery/lines_bars_and_markers/line_demo_dash_control` |
| 15 | +and passing a list of dash sequences using the keyword *dashes* to the |
| 16 | +cycler in :doc:`property_cycle </tutorials/intermediate/color_cycle>`. |
