I have posted this question in KNIME forum and got the satisfactory answer mentioned below
As per concept of command line execution, this requirement does not fit in. Also there is now way for batch executor to open the view of specific plot node.
Hence there could be two solutions
Solution 1
Write the output of workflow in a file and use any charitng plugin to plot the graph and do the drilldown activity.
Solution 2
Use jFreeChart and write the image using ImageWriter node which can be displayed in any screen.
