I started plotting some short horizontal lines on my stock charts to show (for example) the price that is 10% above the current price of the stock. On each line I create a point label that displays the price. I have it set up so that when the current stock price changes to a new value, then the line will move up or down to the new +/-10% level and the label displays the new price. That works fine.
What I want is to manually change the label value from, say, ?$102.25? to be ?+10% $102.25?. In other words, I want to add a constant to the value displayed. But when I do that, then the dollar value no longer changes when the current price changes.
If this were a text box or a Title box, then I could create a reference (link) to a cell value that included both the constant ?+10%? and the variable price ?$102.25?. But I can?t find a way to do that with Series point labels. Is there a way to make a point label value determined by the contents of a cell? (Hmmm, now that I think about it that sort of defeats the whole purpose of using a point label, which I guess is supposed to show the value of a point.)
