Base-Error Series

Base-Error series have two data values per series element. The first value is the base value that is positioned along the Y-axis according to its value. The second value is an error value that determines the length of a bar that is drawn above and below the base marker, denoting a deviation value.

Base-Error series may be mixed with Bar, Area, Line, Hi-Lo, and Hi-Lo-Open-Close series. Base-Error series accept dragged colors to set the Base-Error, line and bar markers, and line color. Other attributes of a Base-Error series may be changed through the Base-Error Series Inspector.

Please Note: This series type should not be confused with the Error Bar feature, whereby Error Bars can be added to a number of the series in Chartsmith. That feature includes the calculation of errors, not the specification of errors as is found in the Base-Error series.


Base-Error Series Inspector

When a Base-Error series is selected in the chart, the Inspector displays the controls that are used to set its attributes. The Base-Error 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 Base-Error series. Changing the values of these attributes does not affect any of the other Base-Error 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 connecting the data points in series.

¥ Base Marker
Sets the graphic used to mark data points.

¥ Error Marker
Sets the graphic used to mark error points.

¥ Marker Size
Sets the size of the graphic used to mark data points.

¥ Marker Color
Sets the fill color of the data point markers and error 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 row labels as they have been provided in the Data View. The numeric labels are the series element values for both the Base value as well as the Error value.

¥ Label Position
Label positioning options are relative to the data marker, if it is displayed, or relative to the data element point if they are not displayed. 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.
