Hi,
is there any possability to plot the data of a vector directly. Because I want to loop over several vector, plot one of them in a graphlayer and overwrite this plot with the next plot of the next vector.
If it isnīt possible to do this, i have to write a loop in Labtalk, write every vector in an wks and plot it. This costs much time.

Hi,
I just tested it without the remove function and it works either! So Í do not need this function!!
Thanks for your help!! |

Thank you, the function works,
but there are problems wit the "RemovePlot" function.
Origin 7 is not able to compile this!!
Is this function still implemnted in origin 7.0 pro or is it a funtion of Origin 7.5 pro?? |

Hi 5*10,
In the previous post I was suggesting creating corresponding X vector. That is actually not required. If you have just a Y col and no X col, Origin would automatically plot against row number, so the code could be simplified such as below:
Easwar
OriginLab
void plot_vec2()
{
// Create and keep a hidden worksheet with just one Y column
WorksheetPage wpg;
wpg.Create("Origin", CREATE_HIDDEN);
Worksheet wks = wpg.Layers(0);
// Delete all cols and add just one Y col
while( wks.DeleteCol(0) );
wks.AddCol();
Dataset dsY(wks, 0);
// Create a new graph page, or use existing one
GraphPage gpg;
gpg.Create("Origin");
GraphLayer gly = gpg.Layers(0);
// say you have a vector with some values, such as:
vector vecY = {1, 4, 5, 7, 8, 5, 5, 4, 3, 2, 9};
// You could change the following to loop over all your vectors...
// Copy the Y vector to the wks col
dsY = vecY;
// Create a curve from the datasets and plot the curve
Curve crv(wks, 0);
// Plot the curve
gly.RemovePlot(0); // remove previous plot if plotting repeatedly
gly.AddPlot(crv);
gly.Rescale();
}

Hi 5*10,
If you were referring to plotting data that is in vector objects in OC...
To make a plot you need both X and Y and thus a curve. And the curve has to be constructed from datasets attached to dataset columns in a worksheet...
So you could use a hidden worksheet that you repeatedly use, from OC, with code such as below:
Easwar
OriginLab
void plot_vec()
{
// Create and keep a hidden worksheet with X, Y datasets
WorksheetPage wpg;
wpg.Create("Origin", CREATE_HIDDEN);
Worksheet wks = wpg.Layers(0);
Dataset dsX(wks, 0);
Dataset dsY(wks, 1);
// Create a new graph page, or use existing one
GraphPage gpg;
gpg.Create("Origin");
GraphLayer gly = gpg.Layers(0);
// say you have a vector with some values, such as:
vector vecY = {1, 4, 5, 7, 8, 5, 5, 4, 3, 2, 9};
// You could change the following to loop over all your vectors...
// create an x vector with "row numbers", same size as vecY
vector vecX;
vecX.Data(1, vecY.GetSize(), 1);
// Copy these vectors to hidden wks
dsX = vecX;
dsY = vecY;
// Create a curve from the datasets and plot the curve
Curve crv(wks, 0, 1);
// Plot the curve
gly.RemovePlot(0); // remove previous plot if plotting repeatedly
gly.AddPlot(crv);
gly.Rescale();
}
