SetAxisScalingMode
int SetAxisScalingMode (int panelHandle, int controlID, int axis, int axisScaling, double min, double max);
Purpose
Sets the scaling mode and the range of a graph axis or the scaling mode and the range of a y-axis of a strip chart.
This function is not valid for the x-axis of a strip chart. To set the x-offset and x-increment for a strip chart, use the SetCtrlAttribute function with the ATTR_XAXIS_OFFSET and ATTR_XAXIS_GAIN attributes.
When you call this function on a digital graph, LabWindows/CVI rounds the min and max values to the closest integer value.
Supported Controls
You can use SetAxisScalingMode with the following controls:
Parameters
| Input | ||||||||
| Name | Type | Description | ||||||
| panelHandle | int | Specifier for a particular panel that is currently in memory. You can obtain this handle from functions such as LoadPanel and NewPanel. | ||||||
| controlID | int | The defined constant, located in the .uir header file, that you assigned to the control in the User Interface Editor, or the ID returned by functions such as NewCtrl and DuplicateCtrl. | ||||||
| axis | int | Specifies for which axis to set the mode and range. The following lists the valid values. VAL_BOTTOM_XAXIS (graphs only) VAL_TOP_XAXIS (graphs only) VAL_LEFT_YAXIS (graphs and strip charts) VAL_RIGHT_YAXIS (graphs and strip charts) |
||||||
| axisScaling | int | Scaling mode for the axis. The following table lists valid values.
|
||||||
| min | double | Minimum axis value when you configure the axis for manual scaling. If axisScaling is VAL_MANUAL, max must exceed min. When you call this function on a digital graph, LabWindows/CVI rounds the min value to the closest integer value. |
||||||
| max | double | Maximum axis value when you configure the axis for manual scaling. If axisScaling is VAL_MANUAL, max must exceed min. When you call this function on a digital graph, LabWindows/CVI rounds the max value to the closest integer value. |
||||||
Return Value
| Name | Type | Description |
| status | int | Return value indicating whether the function was successful. A negative number indicates that an error occurred. |
