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 range of the 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.

If you use this function to change the y-axis of a strip chart, the chart is cleared and all existing data is discarded.

When calling this function on a digital graph, the min and max values will be rounded to the closest integer value.

Parameters

Input
Name Type Description
panelHandle integer Specifier for a particular panel that is currently in memory. You obtain this handle from LoadPanel, NewPanel, or DuplicatePanel.
controlID integer 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 NewCtrl or DuplicateCtrl.
axis integer 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 only)
axisScaling integer Scaling mode for the axis. The following table lists valid values.

VAL_MANUAL Axis is manually scaled, and min and max define its range.
VAL_AUTOSCALE Axis is autoscaled. min and max are not used. You cannot use VAL_AUTOSCALE in strip charts.
VAL_LOCK Axis is manually scaled using the current, usually autoscaled, minimum and maximum values on the axis. You cannot use VAL_LOCK in strip charts.
If axisScaling is VAL_MANUAL, max must exceed min.
min double-precision Minimum axis value when you configure the axis for manual scaling.

If axisScaling is VAL_MANUAL, max must exceed min.

When calling this function on a digital graph, the min value will be rounded to the closest integer value.
max double-precision Maximum axis value when you configure the axis for manual scaling.

If axisScaling is VAL_MANUAL, max must exceed min.

When calling this function on a digital graph, the max value will be rounded to the closest integer value.

Return Value

Name Type Description
status integer Return value indicating whether the function was successful. A negative number indicates that an error occurred.
