I have a share that I cannot be download via yahoo. I do not track the share value for every day (because I'm to lazy). The drawn graph is useless then, because it seems that the missing values are interpreted as "0", causing the image to be scaled in such a way that the actual changes of the share value is no longer visible. I think the line is drawn correctly, but useless because of the scaling. Switching to "point" mode shows all missing values as "0". See attached screen shots.

Reproducible: Didn't try

just as a follow up: this also happens when downloading values for e.g. EURO (internet code "EURUSD=X") because there are no values on weekends. But scaling is much better here (maybe because there is more variation in the values?).

BUG: 259417: Units: graph unreadable when values are missing for some dates ==> "Show origin" allows to show/hide the origin of the graph for a better display
