smaller size of pie charts

Hi all,

Does anyone know how to make the pie chart to display smaller in Appian? Currently, it is displaying bigger than the card KPIs that we have. Any suggestions would be appreciated.

This is our code:

          a!columnLayout(
            width: "MEDIUM",
            contents: {
              a!richTextDisplayField(
                align: "CENTER",
                value: a!richTextItem(
                  text: "Sanctioned Securities by Workflow Status",
                  style: "EMPHASIS"
                )
              ),
              a!pieChartField(
                label: "",
                labelPosition: "COLLAPSED",
                series: a!forEach(
                  items: local!pieChartData,
                  expression: a!chartSeries(
                    label: fv!item.lastWorkflowStatus,
                    data: fv!item.lastWorkflowStatusCount
                  )
                ),
                colorScheme: "RAINFOREST",
                showDataLabels: true(),
                showTooltips: false
              )
            }
          )

Thanks,

Roberta
