Most certainly, you will want your gap width to be something in between the two extremes shown in Figures 4 and 5.In Figure 4, below the chart has the gap width set to zero, whereas the chart within Figure 5 has the gap width set to 250%. Decrease the value for smaller gap width and increase it for larger gap width. You can either directly type the required gap width percentage value within the box provided, or click the Up or Down arrow buttons next to the box to increase or decrease the value by 1% per click.Here, you will find the Gap width option, as shown highlighted in red within Figure 3, below.

Even then, there is scope for some change in the gap width.

The opposite is also true, and you'll see wider gap widths when there are fewer data series. Thus, if you have many data series represented by thin columns, this gap width will be very narrow. Usually the gap width is automatically calculated based on the chart data and the plot area. This gap is set to 150% of the width of individual data series (columns) by default but you can change this percentage value. As you can see, this gap width exists between a set of columns, which together represent a category. The gap width within a chart is the space between two series points, as shown with red arrows within Figure 1, below.
