I have been unsuccessfully trying to programmatically generate PNGs of Plots of a desired size.
I can successfully save a plot as a PNG from a jQt session. require 'plot' pd 'reset' pd */~ i: 10 pd 'show' pd 'save png ',jpath '~temp/myplot.png' However to get it the size I want I need to display the plot at the desired size on the screen. The wiki (https://code.jsoftware.com/wiki/Plot/Commands) suggests that using the `qt` command I should be able to set the display size however this doesn't seem to work and the plot is always displayed at the default size. pd 'reset' pd */~ i: 10 pd 'qt 800 600' NB. no difference to just 'qt' I am able to manually drag the displayed plot window to the desired size and then run pd 'save png' but would like to be able to accomplish this programmatically. I note that the pd 'canvas 800 600' command and the pd 'pdf 800 600' commands seem to work OK - but they don't provide me with a PNG! Is there a bug in pd 'qt'? pd 'canvas 800 600' plot ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
