# Plot on top of a Live Image Preview

Hello,

I am trying to plot a few points on top of a live image preview, but my code returns an error of “Line cannot be a child of Image.” Does anyone know of a way to plot on top of a Live Image, similar to the imageMarker function?

`vidRes1 = handles.vid1.VideoResolution;imWidth1 = vidRes1(1);imHeight1 = vidRes1(2);nBands1 = handles.vid1.NumberOfBands;hImage = image(zeros(imHeight1, imWidth1, nBands1), 'Parent', handles.axes1);preview(handles.vid1, hImage);plot(hImage, 250, 300, 'bo');`

Thanks,

This approach might work for you:

`vid = videoinput('winvideo', 1);vidInfo = imaqhwinfo(vid);vidRes = vid.VideoResolution;imWidth = vidRes(1);imHeight = vidRes(2);numBands = vid.NumberOfBands;hFig = figure;hAxes = axes(hFig);hImage = image(hAxes, zeros(imHeight, imWidth, numBands, vidInfo.NativeDataType));preview(vid, hImage);`
