A simple filters panel has been added under Limit Items on the left sidepanel. Users can now filter out blank values from appearing in each axis through a toggle. These 3 toggles can prevent null, 0 and other empty values from appearing in the chart.
The quick filter has also been added here - the quick filter searches across all columns in the dataset for the given search term. Users can now set a quick filter without having to navigate to the data tab.
A full set of complex filters is available on the Data tab, under each column's header menu.
