Queries that are low in volume with little to no traffic are reported as ‘No Data’. It simply means that there is not enough data available to produce a trends graph. The results are based on the number of searches for that term for that particular month. These results are often quite different than what is found in the Keyword Planner for the same term, however, at this time Google has not revealed how these calculations are done.
Furthermore, you may find that on occasion Google returns no data at all for no apparent reason even if that term is showing results in Keyword Planner. In such an instance, there is nothing wrong with the application but rather what Google is reporting.
