How to Render Particular Part of Data in Flutter CartesianChart?

The Flutter CartesianChart widget provides support to view a specific subset of data from a larger collection. This can be achieved using the initialVisibleMinimum and initialVisibleMaximum properties of an axis.

For example, if you have 10 data points but only need to display data points 4 through 7, you can specify initialVisibleMinimum as 4 and initialVisibleMaximum  as 7 on an axis. This will ensure only the specified range of data is visible.

The following steps explain how to achieve this in the SfCartesianChart.

Step 1: Initialize the Cartesian chart widget with the required parameters and set the initialVisibleMinimum and initialVisibleMaximum properties in the x-axis.

SfCartesianChart(
 // Assigning visible minimum and maximum to the x-axis.
  primaryXAxis: NumericAxis(
    initialVisibleMinimum: 4, 
    initialVisibleMaximum: 7, 
    interval: 1
  ),
)

Step 2: To view the remaining data, you can enable the panning in the zoomPanBehavior and pan the chart.

late ZoomPanBehavior zoomPanBehavior;
 
// Enable the panning
@override
 void initState() {
  zoomPanBehavior = ZoomPanBehavior(enablePanning: true);
  super.initState();
}
 
// Assigning zoom pan behavior to the chart
  SfCartesianChart(
    zoomPanBehavior: zoomPanBehavior,
  )
