GraphView: fix width of the vertical labels

[ggounot]

The same width value was used for both horizontal and vertical labels,
making the vertical labels too wide when the horizontal labels are
wider than the real width of the vertical labels. This fix makes use
of the real width of the vertical labels.

Before and after the fix:

I also noticed this problem and wanted to report it today.

Your workaround works great ! I think the author should test it and approve.

Ok, I tried to enable scrolling and scaling with:

graphView.setScrollable(true);
graphView.setScalable(true);

With that, the graph shrink to 1mm to the left and stays that way:

Other graph's scaling (Advanced graph for example) seems to work ok.

The issue you are describing seems to occur when the viewport is not set.

Thanks for the merge btw.

[azislo]

you are right. For this example I tried to put:

graphView.setViewPort(data[0].getX(), (data[data.length-1].getX()-data[0].getX()));

And then it works. (This code basically means, set viewport to values, like they would be without any viewport set --> from start to whole data range).

However, when I stop pinching (to zoom), the viewport moves a bit to the right or left. When dealing with a large set of values, that could be disturbing. I will probably open a new issue for that and post a video.

The video of the latest jumpy scrolling problem is here:

Should I open a new Issue ?

@azislo
The video is private? Just make it unlisted.
I believe I had the same problem with the viewport jumping around after this commit: ba7ed0f, so I'm actually using an older version for my app right now

@Lauszus
sorry, had problems with uploading to youtube (multiple times) and eventually forgot to change privacy. It should work now.
