HiloOpenCloseSeries in chart about flutter-widgets HOT 1 CLOSED

Hi @evangelme,

Greetings from Syncfusion. We have analyzed your scenario and we would like to share some information regarding the data point indication feature of the financial chart series which when enabled shows indication for datapoints when its high and low values are same or open and close values or high, low, open and close values are the same. To enable this feature, you can set the showIndicationForSameValues to true. Please check the code snippet below for reference.

SfCartesianChart(
               series: <ChartSeries>[
                 HiloOpenCloseSeries<ChartData, double>(
                     showIndicationForSameValues: true, // Indication feature enabled
                     dataSource: chartData,
                      xValueMapper: (ChartData data, _) => data.x,
                      highValueMapper: (ChartData data, _) => data.high,
                      lowValueMapper: (ChartData data, _) => data.low,
                      openValueMapper: (ChartData data, _) => data.open,
                      closeValueMapper: (ChartData data, _) => data.close)
                ]
)

The following are the types of indication when the combination of high, low, open and close values are the same for a data point.

• In the OHLC chart, if the open and close values are same then a horizontal line will be drawn at that value by default.
• If the high and low values are same and with showIndicationForSameValues property set to true then, a thin vertical line is drawn and if API is set to false, the line will not be drawn.
