+The output for an event file corresponding to a blank TensorBoard may
+still sometimes show a few steps, representing a few initial events that
+aren't shown by TensorBoard (for example, when using the Keras TensorBoard callback):
+
+```
+tensor
+   first_step           0
+   last_step            2
+   max_step             2

+   num_steps            2
+   outoforder_steps     [(2, 0), (2, 0), (2, 0)]
+```
+
+In contrast, the output for an event file with more data might look like this:
+
+```
