Do I have one month of Google Locations data?

You can view your Google Locations data in your Google Timeline, to do that for the last month click here:
Google Timeline Last 30 days

The image below shows the Google Timeline webpage with 30 days for Google Location data. In the image you can see a month of blue bars (daily counts of you Location data) and the associate red location dots on the map. Futhermore, if you hover your mouse over the blue bars, the dates associated with each bar will be displayed.

As is shown in the image below, if there is no Google location data, then you will not see any blue bars or red dots.
