Does anyone know why something like this has occurred? I replaced my original data source (the only thing I changed was instead of drag/dropping the table name to the data sources pane, I changed it to a custom sql query with select * from table_name). Here is what the views now look like:
This occurs on multiple panes. The thing is, I can hover over the pane and the outline of the bars for graph will show up when I hover over them.
