Hi-Lo-Open-Close Series

Hi-Lo-Open-Close series have four data values per series element. These series are used by the financial industry to graphically represent a high and low price, and the opening and closing price, often for a day or a week of selling. Hi-Lo-Open-Close series may be mixed with Bar, Line, Area, Base-Error and Hi-Lo series. An element in a Hi-Lo-Open-Close series will not display unless both Hi and Lo values are provided, but the Open and Close values are optional. The line is always drawn from the Lo value to the Hi value, regardless of the values of Open and Close. Hi-Lo-Open-Close series accept dragged colors to set the marker or line color. Other attributes are set by using the Hi-Lo-Open-Close Series Inspector.

Hi-Lo-Open-Close series are also referred to as Candlestick series, and when the rectangular Open/Close marker (see Open/Close Marker Style below) is used this series is often referred to as a Tokyo series.


Hi-Lo-Open-Close Inspector

When a Hi-Lo-Open-Close series is selected in the chart, the Inspector displays the controls that are used to set its attributes.  The Hi-Lo-Open-Close Series Inspector contains a tab view with three tabs: Style, Labels, and Trends.  The contents of each of those tabs are addressed separately below.


Style Tab

The attributes set with controls found in the tab labeled ÒStyleÓ apply only to the currently selected series. Changing the values of these attributes does not affect any of the other series in the chart unless they are also selected.

¥ Line Width and Color
The Line Width slider and the color well set the width and color of the lines in a Hi-Lo-Open-Close series.

¥
Hi and Lo Marker Style
Sets the graphic used to mark Hi and Lo data points. Markers can be different styles for Hi and Lo, but must always be the same size.

¥
Open / Close Marker Style
Sets the graphic used to mark the Open and Close data points. Each selection here sets both the Open and Close points. The style with the open rectangle icon is referred to as Tokyo series style.

¥
Marker Size
The marker size can be as large as 36 point.

¥ Marker Color
Sets the color of the Hi, Lo, Open and Close markers.

¥ Display series on Y1 / Y2 Axis
Associates the series with either the Y1 or Y2 axis (the axis must be active in order to associate a series to it). The data range of the associated axis will determine how the series is drawn.

Labels Tab
 
The contents of this tab are used to control the content, color, position and rotation of the series labels.

¥ Labels
A switch titled ÒLabelsÓ at the top of the tab view panel will enable or disable the series labels for the selected series.

¥ Label Content
The content of the data labels is set to:
Data - numeric labels
Text - textual labels
Text and Data - both textual and numeric values in the labels

The textual labels contain the Hi, Lo, Open or Close designation. The numeric labels are the series element values.

¥ Label Position
Label positioning options are relative to the data marker.  Series labels can be double-  clicked to deep-select them, then dragged freely across the chart. When this is done, the label position is set to ÒCustomÓ.

¥ Label Color
The Label Color sets the display color of series labels.

¥ Label Rotation
The Rotation controls set the rotation of all of the series labels.
 


Trends Tab

The contents of the Trends tab is used to add trend lines to the selected series. Any number of trends can be added, each with their own set of attributes, but all associated with the data of the selected series.

¥ Add Trend / Delete Trend
At the bottom of the trends tab are two buttons used to add and delete trends.  Initially only the Add Trend button is enabled.  When the Add Trend button is clicked, a single trend is added.  For each added trend, an item is added to the popup button that is toward the top of the Trends tab.  This popup button displays the trend label for each of the trends that have been added, and is used to select a trend.

To delete a trend, select the trend from the list of trends in the popup button toward the top of the Trends tab, then click the Delete Trend button.

¥ Type
The mathematical model for a given trend can be set using the Type popup button.  If the trend type has a modifier value, the control for that value is displayed to the right of the trend type popup.  For example, the Polynomial trend type has an Order modifier, and the Moving Average trend type has a Period modifier.

¥ Active
The Active switch is used to activate and deactivate a trend.  When a trend is deactivated, it is not displayed in the chart and is not referenced in the chart legend.

¥ Show Entry in Legend
This switch is used to include or exclude an entry that represents the trend from the chart legend. 

¥ Draw in front of series
Allows you to set the trend to draw in front of or in back of the associated seris. 

¥ Label
The default label for a trend is Ò<Series Name>(Trend #)Ó.  This label can be modified with the Label textfield.  This label is used to identify the trend in the chart legend, and is also used to identify the trend in the trends popup toward the top of the Trends tab.  

¥ Line Width and Color
Used to set the width and color of the trend line. 

¥ Equation Annotation
You can drag a textual annotation from this icon well that will display the mathematical equation computed for the associated trend.
