When creating a new chart in SSRS, you may find that not all of the labels are being displayed on either the vertical or horizontal axis. This will happen when the chart tries to determine how many labels it can show using the default setting. Sometimes this isn’t the best solution. For example, as you can see in my chart below there should be plenty of room to show all of the labels but it decides not to.
In this case we definitely want to show all of the labels. To do this we will need to adjust some settings. Double click on the label names on the chart.
On the right hand side of Visual Studio, you should now see the Chart Axis values on the Properties area.
Under the Interval attribute, change the value from ‘Auto’ to 1. This will specify that we want to show labels on every occurrence.
Re-run the report and now you can see that all of the labels are shown.
