Namespace: charting
Properties
| Name | Type | Description | |
|
BackColor | object | Get the background Color of the chart. |
|
|
ChartViewHasFocus |
bool | True when the chart is active and has focus. |
|
|
ClientWindow | object | Gets the current ChartWindow object. |
|
|
CurrentSubgraph | int | Gets the number of the chart subgraph in which the study containing the StrategyHost is inserted.. |
|
|
DataStreams | object | Gets the collection of DataStreams associated with the chart. Note that this property contains information about all the data streams in the chart, regardless of whether all of the streams are used by the analysis technique. For example, an analysis technique might refer to Data1 and Data2, while the chart contains 5 data streams. In this case, all of the 5 data streams in the chart will be accessible through this DataStreams property. See DataStreams. (For information about the data streams that are used by an analysis technique, rather than all of the data streams in the chart, see the DataStreams property of the AnalysisTechnique class.) |
