This command calls a plot command on the server with an array of data. The server's plot command produces an image showing a plot of the data. The local calq client then displays this image. Note that the image will display outside of the text box for the results. You may need to scroll down the screen to see it. This command is asynchronous, depending on things like the network and server's availability.
With HTML5, this command was re-written to allow the figures to appear as pop-up windows. Similar to imshow in v2.1.9.
