A graph, similar to the 'Line Chart' or the 'Scatter Plot' Visualizations, but instead of displaying dots or lines, it will display vectors.
The need is to display vectors in a 2D space. It is possible to do it with R (see image attached) but the result is a still image. It would be a great help if it where dynamic like the other visualizations.
It is currently possible to vaguely do it using a Scatter Plot, setting the axis to the x and y coordinates, but the vector's direction is still impossible to display.
Hi Jeremy, I see. What about using the size axis to represent the length?
Thank you for your quick answer Niklas, but this doesn't solve my use case.
What I have is a data table with the columns x1, y1, x2 and y2. I need to display each row as a vector, where (x1,y1) are the coordinates of the beginning of the vector and (x2,y2) the end of the vector.
I've tried your solution, it represents the origin and the direction perfectly, but it does nor represent the vector's magnitude (it's length).
I tried combining your solution with the Line Connection function of the Scatter plot, but the result isn't that good (see linked image).
Hi Jeremy, you can set the vectors direction by the rotation axis in the scatterplot: http://docs.spotfire.cloud.tibco.com/spotfire/GUID-493C5203-43F6-4871-8BDD-7A9856BDAD13.html
It is available in Spotfire 7.10 and later. Does this solve your use case?
