Animation isn't smooth when the data points are different

**Describe the bug**
The expected behaviour is to have a smooth animation when the chart gets updated like below. In this case, the minX, maxX, minY, maxY are same in chart 0 and chart 2

However, I sometimes do not find animation and it suddenly jumps to the location. Here, the maxX, maxY are different in chart 0 and chart 3.

**To Reproduce**
The modification is in `scatter_chart_sample2.dart` file ans can be found [here](https://gist.github.com/prajwal27wiijii/0a5c7e1332daa81ad64fc60208992ee5).

**Versions**
- which version of the Flutter are you using? -- 2.10.1
- which version of the FlChart are you using? -- 0.50.1

Start with the modified scatter_chart_sample2.dart file from the linked reproduction and compare the updates shown in chart 0, chart 2, and chart 3. Investigate why changing maxX or maxY causes the scatter chart to jump instead of animate. Done means the reproduced data-point updates animate smoothly even when the chart bounds differ.
