Modify / Disable entries in Easy Chart Popup

I’d like to remove the "Save as… " and “Print” options from the Popup right on the easy chart.
Any Ideas / possiblity for that? I found only these guys here, which will do the same as the properties right on the easy chart. Haven’t found anymore specific for the right-click user menu…

def configureChart(self, chart):

secondly: is there a way to open the popup in a different way? touch screens are kinda bad with right-click actions…
