Setting Filter Components As Mandatory

Version

Application Scenario

You may use large data volume during dashboard creations. If the filtered condition is cleared and all data is displayed, a crash may be caused due to the overloaded query and excessive results. In this case, you can set the filter component as mandatory to ensure that only part of data is displayed when you use components. After setting, the last filtered data is displayed by default after you clear the filtered condition.

For example, the repayment data after 2014-06-01 is still displayed by default after you clear the filtered condition 2014-06-01 during dashboard viewing, as shown in the following figure.

Implementation Method

You can select Set as Mandatory to ensure that some data is always displayed. If the filter condition is cleared, a prompt pops up displaying "Required fields cannot be empty", and the selected data before clearance is filtered by default.

This document uses the built-in data table Pareto Data Analysis as an example.

Component Creation

Create a component through the example data table, as shown in the following figure.

Filter Component Adding and Mandatory Option Setting

Add a dashboard, click Filter Component, drag Data Interval Filter Component to the dashboard, drag the field Sales Date to Field, select Set as Mandatory, set Data Interval to 2014-06-01 - Unlimited, and click OK, as shown in the following figure.
