Is there a way to hide the "hover over " pop up on the chart Help icon ? My user does not want the hover pop up they only want the display of chart help when the ? is clicked... I have checked doc/user/chart attributes, unless I missed it I don't think there is a way.
I'm not sure about that option. The workaround, you can create a small text with 'Question mark' and place it in the top right corner of the chart. then, create the Action to show /hide the help text box (another text box)
You can't change it in properties. What you can do is remove it all together and instead use a text object with an image of the help icon place on the layer above the caption bar. You can then tie the text display to a conditional visibility variable which is triggered on a click action.
