LineChart position when zooming

Feb 13, 2014 at 2:10 PM
Hi, I'm using a LineChart and I have a particular problem.
If you zoom in and out the chart loses its reference with respect to the y-axis tick points are displayed in the wrong way. Zooming out is as if the position of the points were only approximate and zooming far ahead you see the exact value of the point shown in the graph.

For example if I have a point with y-coordinate equal to -0.8, if I look at the chart from a distance I see the point that even falls below the notch of -1. If I zoom in, I see that point begins to rise until it reaches its true value.

I sno sure that the values ​​are correct then I would like to know if this is a bug in the library and if and how I can fix it.

Thanks
Andrea
