Customize Symbol - Scaling
Use the Scaling tab to modify the scaling settings for the y-axis of a symbol data in a Chart Analysis window. When applied to its own sub-graph, the y-axis displays values specific to the symbol data.
Access from a Chart Analysis window using the Data
> Edit Symbol menu sequence and select the Scaling
tab.
To
access the Customize Symbol dialog automatically after a chart has been created,
use the Settings > Preferences menu sequence. On the
General tab, select the Prompt for customization when creating new Chart Analysis
window check box and click OK.
Axis 
Determines which axis to use for scaling the data series and on which sub-graph to display the data series.
- Scale On - Select Right Axis, Left Axis, or No Axis from the drop-down list to determine which axis will be used for the symbol scale for the specified sub-graph.
- Sub-graph - Select the number from the drop-down list to plot the actual symbol data. Hidden causes the symbol data to not be displayed on any Sub-graph.
To toggle the display of the left/right price axis, use the Settings > Window menu sequence and select the General tab. This does not affect the left or right vertical scaling that is applied from the Edit Symbol tab.
Type
Shows whether to use Linear or Semi-log scaling for the specified axis.
- Linear - Produces a scale with regularly spaced increments that represent the same value. For example, a move from 12 to 14 would take up exactly the same amount of vertical space as a move from 26 to 28. Another way to look at it is that on a linear axis, each y-axis increment of 1 point will be the equally close to each other increment.
- Semi-Log - Produces a scale weighted towards the percent of change. For example, a move from 16 to 18, which is an 11 percent increase, is given more space on the scale than a move from 30 to 32, which is a 6 percent increase. Another way to look at it is that on a semi-log axis, the y-axis increments of 1 point at the top of the axis will be closer together that the same 1 point increments at the bottom of the axis; changing the scale type of the charted data.
Range
Specifies how the scale range is determined and whether to include additional factors in range scaling. Contains the Automatic, Fixed and Movement Size range types.
- Automatic:
Scale Range Based On:
- Data Range On Screen
- Entire Data Range
- Center Last Price - Automatically places the last price at the center of the y-axis for the symbol scale.
- Expand Range to Include Studies - to have the range of studies applied on the symbol's sub-graph included in the range calculation.
- Expand Range to Include Account Open Order Lines - to have the range of account open order lines on the symbol's sub-graph included in the range calculation.
- Sub-graph Margins - Allows you to enter a value of how much additional space to display at the top and bottom of the indicator's sub-graph based on a percentage of the sub-graph size for each of the top and bottom margins.
- Percent Below/Above Last
- Percent Below - Enter the desired value for the below percentage to be used to set the range in the appropriate % box.
- Percent Above - Enter the desired value for the above the last price percentage to be used to set the range in the appropriate % box.
- Fixed - Sets a specific minimum and maximum data value to be used to determine the range of a sub-graph.
- Movement Size - Enter the desired value for the approximate screen size (inches or centimeters) that will represent a specified number of price points.
Display
Customizes the axis increments and formats the displayed values.
- Custom Axis Increment - Enter the desired number of points to specify y-axis increment spacing. Numbers may not appear next to each increment marker since number spacing is automatically determined based on chart and screen size.
- Custom Decimal Places - Enter the desired number of decimal places to use for each displayed y-axis data number.
- Divide Axis Labels by - Displays y-axis numbers based on the raw data value divided by selected value.
- Use 1000s Separator(,) - Specifies whether y-axis numbers are displayed with or without a separator symbol. (i.e. 11,231 vs 11231).
Set as Default - Check this setting to use the above settings as your default for other symbols. This option is only available for EasyLanguage documents.
