Axis - Incorrect AxisRange calculation in case of a small argument data interval

Bar chart does not display properly, especially when the data range is small.

Steps to Reproduce:

I've attached a small sample program that show 3 different issues.

1. When the form load, it generates some random numbers and update the chart. The data range is not that small.

2. Test 1 button generate small numbers with a small range.

3. Test 2 button generate small numbers with a small range and then manually sets the bar width.

4. The last test button generates some numbers which the chart show correctly. This is sample of what I expected to see for 1, 2, and 3.

Actual Results:

1. Bars show up overlapping.

2. Bar chart is not showing the bars, just one block.

3. Bar chart showing only 1 bar.

4. Bar chart properly showing.

Expected Results:

All the different samples would show bars representing the different values with each bar side by side like number 4.
