Description

The x-axis in line charts doesn't display all tick values correctly, especially when using numeric values as x values across multiple series. The last x value (5) is missing from the axis, and data points are misaligned with their corresponding tick marks.

I had previously reported a similar issue regarding x-axis tick misalignment in bar charts: #4858

Steps to Reproduce

1. Create a line chart with multiple series
2. Use numeric values as x values (1, 2, 4, 5)
3. Observe the x-axis rendering and data point alignment

Expected Behavior

The x-axis should display all unique x values (1, 2, 4, 5) as tick marks, and data points should align with their corresponding tick marks.

Actual Behavior

The x-axis only shows 1, 2, 3, 4 as ticks, omitting 5. Additionally:

• The data point for 2 appears before the 2 tick mark
• The data point for 5 is incorrectly positioned above the 4 tick mark

var chart = new ApexCharts(document.querySelector("#chart"), options);

chart.render();
