You will notice that the chart does not label every category on the y-axis. This is due to an automatic algorithm that calculates an interval at which to display labels in order to prevent label collisions. If you want to display all categories on the chart, you must specify an axis interval of 1.
To display all sales persons along the category axis of a bar chart
Switch to Design view.
Right-click the y-axis and click Axis Properties.
In the Category Axis Properties dialog box, on the Axis Options page, type 1 for Interval.
Click OK.
Note
If the names on the axis are unreadable, consider increasing the size of your chart, or changing formatting options for the axis labels. For more information, see Formatting Axis Labels on a Chart.

To improve the readability of the chart values, you might want to move the chart legend. For example, in a bar chart, where bars are shown horizontally, you can change the position of the legend so that it is above or below the chart area. This gives more horizontal space to the bars.
To display the legend below the chart area of a bar chart
Switch to Design view.
Right-click the legend on the chart.
Select Legend Properties.
For Legend position, select a different position. For example, set the position to the middle bottom option.
Note
You can also drag the legend to a new location directly on the design surface.
When the legend is placed at the top or bottom of a chart, the layout of the legend changes from vertical to horizontal. You can select a different layout from the Layout drop-down list.
Click OK.
Note
If the names in the legend are unreadable, you may want to consider increasing the size of your chart, or changing formatting options for the legend. For more information, see Formatting the Legend on a Chart.
Next, you can change the chart title and axis titles and add formatting.
To change the chart title above the chart area of a bar chart
Switch to Design view.
Right-click on the chart title at the top of the chart and click Title Properties.
Replace the Title text field with the following text: "Sales Person YTD vs. Last Year".
Click anywhere outside the text.
Click Preview. Your report should look similar to the following example:
