The stride refers to the *array* stride. So a stride of < 1 makes no
sense.

An rstride of 1 will plot every row. A cstride of 3 will plot every 3rd
column. If your data is in a 2D array of dimensions 100x100, say, then
setting rstride=5 and cstride=5 will plot every 5th row and every 5th
column, giving 20 lines in each direction. The kwargs rstride and
cstride do not care about the domain of your data.

Hope this helps.
