It would be nice for the Range Selector Viz to reflect the true "Max" or "Min" number even when assigning a default range that is lesser than the max or more than the min instead of showing the min and max based on the range selected.
With this, the users are presented with both the default range and the true max and min which they can also utilize and adjust to.
See how it looks in the controls, where the value is set to 29 but still showing the real max number 128? While in the chart, the available max is now limited to 29 and there are no options to default the range up to 29 but also show that the data is available up to 128.
This (input + slider) look and functionality would be perfect but it's only available for variables right now.
