I am using Origin 7.5, my question is how to customize origin so that it saves the settings upon exit, I want it to let's say to save the peaks number of decimal place to equal to zero, or to turn off the speed mode for ever? So I don't have to change them manually every time.
I believe this is a general question and it does not really depend on the version
You could turn off the speed mode of a graph and then save the graph as a template. Then when you create the same type of graph next time, Origin will always turn off the speed mode. To save a graph template, please right click on the head of a graph window and select Save Template As to open a dialog. Then click the Save button to save it with default settings.
For another question, you said you want to "save the peaks number of decimal place to equal to zero", I am not very clear on what this means, could you give more explanation about it?
