Microsoft Excel sorts slider buttons alphabetically and numerically. Fortunately, you can add a custom sort list to sort the buttons in a more meaningful way, when necessary.

Excel Slicers are easy to use visual controls added to Excel that allows to quickly and easily filter data in an interactive way by selecting values from a list.

Slicers were first introduced in Excel 2010 and enhanced a lot in Excel 2013. In Excel 2013, if you want to add Slicer to your charts, select the data range and click on insert > Slicer.
