How does one remove a dataplot from a layer in Origin C?

LT_execute gets back into LT and the general problem of Active window and Active Layer. so OC provide page and layer level LT_execute so that the LT string passed into those versions of LT_execute can assume that object as the Active window or Acitve layer. This is very much like the LT version of win -o {script} or layer -o {script}.
It is easy to forget all these little problems and hidden assumptions in the LT world once you are more comfortable with OC, where everything is clear by simply looking at the C/C++ code.

Thanks, Ruthven. That's essentially what I ended up doing.
BTW, you use glayer.LT_execute() in your example. That works fine, but so does just LT_execute(). Are there any guidelines for using one or the other?

Until 7.5-SR1 comes along you may wish to try this workaround which CP posted some time ago ..
bool remove_data_plot(GraphLayer glayer, DataPlot dp)
{
string strName = dp.GetDatasetName();
DataPlot dp1 = glayer.DataPlots(strName);
if(NULL == dp1)
return false; // given data plot does not belong this specified layer
string strTemp;
strTemp.Format("layer -e %s", strName);
glayer.LT_execute(strTemp);
return true;

I am afraid that was missing in 7.5 release and has been added to SR1 (5325).
