SetCtrlAttribute (, , ATTR_ZOOM_STYLE, );
兄弟试试用这个属性设置的控件！

找到解决办法了！

谢谢版主的帮忙。
我试了版主说的那条语句，不过它只能设置graph控件的zoom Style属性，
后来我从帮助文件中找到了SetAxisScalingMode (int panelHandle, int controlID, int axis, int axisScaling, double min, double max)函数;
int SetAxisScalingMode (int panelHandle, int controlID, int axis, int axisScaling, double min, double max);
PurposeSets 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.
可以用它来设置graph控件视口左右端的X轴坐标，进而实现看似移动和缩放的效果。
