In App Charts allow for a graphical Report (chart) to be contained within a Record. The Field is simple in that it renders a defined Chart, but the Chart itself needs to be built as a Report first within App Studio. The In App Chart requires following a three step process.
Step 1: There needs to be a source for the data that is in the chart. Create a GridField with Grid Sub Fields that can become the axes, series and labels for the charts. Grid Fields have to be used for Charts at the In-App Record level in order to ensure categorical data is displayed fully. For example, if the x-axis was 'Month' and Sub Fields for Jan-Dec were not made, when the Chart is in a Record it would only display data for the Month specified in the Record, say January for example and not any others.
Step 2: Create the chart in the Report area of App Studio. When building your chart select the Grid Field that you have created in Step 1 as the 'In-App Data Source Field'. You will then be able to choose from the Fields in the chosen GridField to build up the configuration on your chart.
Step 3: Render the chart in the Record. Create a new Field and select Field type 'InAppChart'. Then select the Report that you have built in Step 2 and add this new Field to your Template.
