as we can see in attached png, first image is what we can have with thingworx 8.5 and label chart widget. The second one show what we obtained when we migrate to Thingworx 9.2 (widget ptcschartlabel). The legend is displayed like a grid (2*2), and i see no option linked to that. What i would like to have is represented by the third image, the legend bottom and in one line. (sorry for my "particular" english, i'm french !)
We performed some testing and it appears to be presented in a grid formation once you add more than 3 series. We're not seeing an option to change it. However, you might try looking at CSS for formatting it. We played around with this a little and were able to format the legend vertically. i would assume there's an option to change it to horizontal.
As an alternative, you may want to post a suggestion on the ThingWorx Ideas board. This will allow others to vote for it, increasing it's chances of being included in a future release.
