[XYChart] incorrect spacing between data points

[OG-NI]

Description

When using the XYChart in combination with a numeric range for the x-axis, the distance between the individual data points is not always correct. This leads to the data being distorted in an unpredictable way and data points on the right hand side of the diagram to be cut off.

Steps to reproduce

Copy the code sample below or create a XYChart with a numeric range where $\text{max} - \text{min} + 1 \ne \text{number of data points}$.

Code Sample

xychart-beta
    x-axis 0 --> 2
    line [0, 1, 0, 1]
    bar [1, 0, 1, 0]

Setup

Suggested Solutions

Change const step = (max - min + 1) / data.length; in xychartDb.ts to const step = (max - min) / (data.length - 1);.
