Pie Chart control

A Pie chart is a type of graph in which a circular graphic is divided into sectors that represent a proportion of the whole. It is one of the most used chart types for visual representation of data.



UI Properties

  • Label : Label is the text that is over above the control and helps the user to understand the purpose of the Pie Chart Control.

  • Properties : These properties help you customize the Label by changing the text size, weight ( Light, Normal, Bold, Extra Bold, X Extra Bold), alignment (Left, Center, Right, Justified) and color of the label.

  • Type : The Type field is automatically generated depending upon the type of control used. In this case, it is a “PieChart” type.

  • Unique Name : A Unique Name is used to uniquely identify a control in your App. Every control that is added on the screen gets an auto-generated Unique Name on the basis of the Label name given to the control.

  • Tooltip: This allows you to add the Tooltip text that would provide a hint to the user for providing input. The Tooltip icon would be visible if you switch on the Show tooltip icon toggle property available below.

  • Description: Is the description that you can add for your controls. The Description would only be visible if you switch on the Show Description toggle property available below.

  • Show Tooltip Icon: This allows you to toggle switch ON or OFF to show or hide the tooltip icon where the tooltip text would appear.

  • Show Description: This allows you to toggle switch ON or OFF to show or hide the Description text.

  • Hidden : The hidden option helps you to hide the field from the user. This might help to perform any actions that you do not want the user to see. You can also use it to display certain fields only when a specific condition is met/not met.

  • Caching : When the caching option is selected and if a LOOKUP formula is applied to this control, the state that the LOOKUP returns will be cached and the user will be able to see this state of the field even when the user accesses the microapp later with no connectivity. This option is required when you want your app to be accessible in offline mode as well and getting the latest data from the sheets always is not critical.

  • Hide Label : This option hides the label of the control from the view.

  • Trigger dependents: When you Disable Trigger Dependents, it helps you to reduce or optimize the unnecessary evaluation of the dependent control’s formula. For a detailed explanation refer to this article here .
    By default Trigger dependents is enabled. However, in complex apps by switching it off, you would limit the evaluation in the dependent control and in turn ensure quicker response times.

  • Chart Height : This allows you to set the height of the Pie chart. By default, the height is set to 350 px.

  • Aggregate Data : This option can be used when you need to quantify the number of certain elements using a chart. For example, if you have a list of employees with department names you want to plot graphs about how many employees are in each department you just bind the department column and aggregate it.

  • Data Values : When this option is selected you will be able to see the values corresponding to each arch next to it.

  • Legends : It is the area of a chart that helps describe each of the parts that help make up a chart. You can enable legends by selecting this option.
