You can add an offset to the x-values in the line chart in order to align them to their respective columns as shown in the code snippet below:
dps1.push({label: chart.data[0].dataPoints[i].label, x: chart.data[0].dataPoints[i].x - 0.25, y: yPercent1});
dps2.push({label: chart.data[0].dataPoints[i].label, x: chart.data[0].dataPoints[i].x + 0.25, y: yPercent2});
Please check this updated StackBlitz for a working example.

Justine,
Can you kindly create a sample project reproducing the issue and share it with us over Google Drive or OneDrive so that we can look into the code, run it locally to understand the scenario better, and help you out?

Adding space between columns in a multi-series column chart is not possible as of now. However, as a workaround, you can use stripLines to achieve the same.
Please check this JSFiddle for a working example.

@kmi,
CanvasJS plots the datapoints in the same order that it is passed to the chart, without sorting or grouping. interval and intervalType properties are used to display axis labels at the specified interval and not to group datapoints.

Meena,
You can make the indexlabel more readable by either increasing the font size of indexLabels by setting indexLabelFontSize property or changing the color of indexLabels by setting indexLabelFontColor.
