Widget top and bottom bounds attribute inverted?

Question

Hi, I was doing some widget plotting and detection earlier and found that widgets seem to have “reversed” values in their y-axis top and bottom bounds property. For example a fresh widget which I created with miro shape creator had these bounds:

This might just be a result of different plotting technique or something but from what I know bottom y axis point should always be smaller than the top y axis point. Is this “inverted” on purpose? If yes what is the idea behind this?

Also I have not made any tranformations / translations on the board or widgets. And what really bugged me is that the x-axis left and right points are plotted normally (left is on the left and right is on the right) unlike the y-axis points. From which arises another question is this actually plotted on the board in reverse or are the values just passed to the wrong attribute inside the widget data?

@Sami Ljimari Miro coordinatesappear to follow html / SVG / Canvas standards. Which has Y inverted.AndYeah.. its always a mind-bender to do geometry in this system.http://drawingincode.com/lessons/concepts/coordinates/index.html

@Max HarperThank you for the information. I didn’t know that SVG had inverted Y.This probably is the reason why miro board has it inverted too as you said, although I wonder if there are any upsides to using it or if it is just a preference of the development teamAnyway I hope if someone else decides to manipulate widgets in a similar way and finds themselves confused about the plotting, they can see your answer to make it more clear and not waste hours on testing like me
