Create a Simple Bar Graph on a Report


You need to create a simple bar graph on a report. Microsoft Graph or the Office Web Components would probably work, but you’re hoping for a simpler native Access solution. You need a bar for each row showing the relative score for each student. Can’t you do this with the standard Access controls?


You can place a rectangle control in the detail section of your report and set its width during the Format event that occurs as Access lays out each row of data.

To create a bar graph like this one in your own applications, follow these steps:

  1. Create your report, including the text data you’d like to show for each row. The sample report shows the Name and Score fields from tblScores, using controls named txtName and txtScore.

  2. Add a rectangle control from the report toolbox and place it next to the data in the detail section. In the sample report, the rectangle’s control name is rctBar. The control’s width isn’t important, because you’ll be adjusting that programmatically ...
