I would have assumed it would do auto scaling, the current solution is to set `x_ticker=False`. I am using a _qt4agg_ backend for matplotlib, not that that should matter.\r\n\r\nWhich then creates the second issue, a plot with zero height. The values of the SPD are normalized, so should be visible as is.\r\n![figure_1](https://cloud.githubusercontent.com/assets/22137450/21082476/30cc934a-bf91-11e6-80d7-431cbda56c97.png)\r\n\r\n"}}
