Working with Sub-Charts

Fields displayed in a Chart View can be displayed in one or more sub-charts within the same window. Sub-charts let you display fields with different value ranges over the same date range. For example, price data and volume data could be displayed in a single Chart View using sub-charts. Sub-charts also let you separate fields visually so that you can analyze them in detail.

&  For a step-by-step introduction to this topic, see the tutorial called Displaying Charts.

Displaying a Field in a Sub-Chart

The quickest way to display a field in a sub-chart is to select Display field in a new sub-chart on the Display Chart Dialog while you are adding a new field to a chart. The new sub-chart will be denoted by a dashed line in the field list.

If you would like to move an existing chart field to a new sub-chart, select Move Field to a New Sub-Chart from the context menu for the field you would like to move. You can also drag chart fields to new or existing sub-charts using the mouse.

Displaying Signal Fields in Sub-Charts

Signal fields are displayed as value lines when they are displayed in their own sub-chart or in a sub-chart with other signals. This allows you to see the actual value of the field rather than just when it crosses threshold values. By default, the value range of a signal sub-chart is set to a constant range from -1 to 1.

Signal fields that are added to sub-charts with non-signal data in them are typically displayed as entry/exit arrows. By default, only the first of a series of redundant signals is displayed. For example, if several enter long signals appear in a row, an arrow will only be displayed for the first one. To display arrows for all signals, select Change Display Properties of Field … from the context menu for the signal field and select Include redundant buy/sell arrows in display on the Change Display Properties Dialog.

Ä    Note: In order for a signal field to recognize non-signal data, it must be added to the Chart View after that data.

Changing the Order of Sub-Charts

If you would like to change the order of the sub-charts in a Chart View, you can use drag and drop to move the sub-charts. Position the mouse to the left of the values in the y-axis or to the right of the sub-chart in the Chart View, then press and hold down the left mouse button. The mouse cursor should change to an arrow with a chart next to it. While holding the left mouse button, move the mouse up or down in the Chart View to adjust the order in which the sub-chart is displayed.
