The HighLowOpenClose Chart is generally used in stock analysis. The chart combines four independent values to supply high, low, open, and close data values for each data point in a series.
Consider a stock market scenario in which a stock is to be analyzed in terms of its price for one week. The analysis needs to depict the stock price summary, so that the growth/decline can easily be interpreted.
The HighLowOpenClose Chart can be used in this case.
| Day | High | Low | Open | Close |
|---|---|---|---|---|
| Mon | 450 | 190 | 350 | 380 |
| Tue | 470 | 200 | 300 | 390 |
| Wed | 420 | 160 | 290 | 350 |
| Thu | 440 | 220 | 330 | 400 |
| Fri | 500 | 210 | 350 | 470 |
| Sat | 390 | 250 | 310 | 360 |

The above chart displays the stock summary for a particular week.
See the following code for implementing the scenario:
' create a datatable Dim dt As New DataTable("Stock Value Summary") ' add columns to the datatable dt.Columns.Add("Day", GetType(String)) dt.Columns.Add("High", GetType(Integer)) dt.Columns.Add("Low", GetType(Integer)) dt.Columns.Add("Open", GetType(Integer)) dt.Columns.Add("Close", GetType(Integer)) ' add rows to the datatable dt.Rows.Add("Mon", 450, 190, 350, 380) dt.Rows.Add("Tue", 470, 200, 300, 390) dt.Rows.Add("Wed", 420, 160, 290, 350) dt.Rows.Add("Thu", 440, 220, 330, 400) dt.Rows.Add("Fri", 500, 210, 350, 470) dt.Rows.Add("Sat", 390, 250, 310, 360) ' clear data series collection FlexChart1.Series.Clear() ' create data series Dim series1 As New C1.Win.Chart.Series() ' add the data series to the data series collection FlexChart1.Series.Add(series1) ' specify the datasource for the chart FlexChart1.DataSource = dt ' bind X-axis and Y-axis FlexChart1.BindingX = "Day" series1.Binding = "High,Low,Open,Close" ' set the chart type to candlestick FlexChart1.ChartType = C1.Chart.ChartType.HighLowOpenClose
