I have a python custom search command that generates a plot i.e. plot.png. The custom command writes the image file to the app's /appserver/static/images folder. A dashboard displays plot.png so an analyst can make changes to the custom search command's arguments. The custom search command is run again and the image file, plot.png, is overwritten in the apps static images folder. Is there a way to have the updated image display, in a production environment, without restarting Splunk and reloading the page?
