Some graphs on the dashboard depend on the classification info. If there is no active classification process on your search, the graphs on the sentiment change and the brand perception will not be created.
Besides, the graphs on the dashboard are created based on the latest 12-hour or 24-hour. During this period, there might be no enough data for a graph. In cases like this, you might first control whether or not you have enough data in the last 24-hour period and then if such data is classified.
