How to Change Axis Name of Graph Control in LabWindows/CVI

We can use the SetCtrlAttribute function to change an Axis name programmatically in LabWindows/CVI. Just set the ATTR_XNAME or ATTR_YNAME attribute to any name you’d like to use in this function.

For example, change the top X-Axis name of a graph, we can use the following code.

// Make the top x-axis the active one
SetCtrlAttribute (panel, PANEL_GRAPH, ATTR_ACTIVE_XAXIS, VAL_TOP_XAXIS);    
// Set the name
SetCtrlAttribute (panel, PANEL_GRAPH, ATTR_XNAME, "Axis Changed");
