modelXYPlotWithImage
XY-plot with background image
Information
XY-plot with an image as background. The plot is visualized in the tools diagram view.
Special case
If the x and y vector contains only one data point a circle will be visualized instead of the polyline.
Coordinate transformation
The coordinate system of the diagram is built up by defining (x,y) values at two positions in the image, point_1 and point_2. For point_1 and point_2 the corresponding image pixel coordinates, point_1_imagePixelCoord and point_2_imagePixelCoord needs to be defined.
Image pixel dimension and coordinates of the specified image can be found by using an image program such as Paint.
