Total agree with both suggestions, especially one.
There is the Security Performance graph in which you can select multiple securities but again you can only export a picture and the scaling of the value axis can be an issue if the security values are not in the same range. Perhaps It may be of some help. If one of the selections was the ability to set the value axis as a relative change that could be of use.
Thanks for the tip. Yes the Security performance report helps. and overcomes issue of being able to graph and compare several securities. But ability to export saved security history in text form that can be used in excel or other fomats remains an issue.
