今天帮您找了一下，看到一个，您试试行不行：

int SetAxisScalingMode (int Panel_Handle, int Control_ID, int Axis, int Axis_Scaling, double Min, double Max);

cpubbs

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.
