Thanks MC!
Unfortunately, that did not work. I changed the options as follows,
and my labels are still slanted.
Options options = Options.create();
options.setHeight(250);
options.setLineSize(1);
options.setPointSize(0);
Options hAxis = Options.create();
hAxis.set("slantedTextAngle", 90.0);
options.set("hAxis", hAxis);
options.set("legend", "bottom");
Any other suggestions?
