TRSDBHighLowAverageChart Class

Scroll Prev Top Next More

The TRSDBHighLowAverageChart component is the database aware version of the TRSHighLowAverageChart. The TRSHighLowAverageChart component is a TRSCustomSparseBarChart descendant that represents a high/low/average bar chart, i.e., bars that can show a vertical range. The High/Low/Average Bar Chart displays each chart value ( TRSHighLowAverageChartValue ) as a vertical or horizontal bar (depending on  Orientation). A HighLowAverage chart is something like a combination of a line-chart and a bar-chart: each bar represents three important pieces of information: the Average (as line on side of bar), and the high and the low. Each value draws a separate bar and the order of the bars is based on the order of the TRSHighLowAverageChartValue in the collection.

The values for the chart are created by reading a dataset (database table or query) specified with the    DataSource property. Each record in the dataset provides one value for the chart, where the DataFieldX property specifies the field to use for the X value, DataFieldClose specifies the field to use for the Close value, etc.
