Chart Widget on dashboard



I have created a report in order to create a chart widget in a dashboard, which I did, but because the variables are 2 large categories, this looks very big and it doesn't look good on the dashboard. What I would like to display on the chart widget is how many types of transactions are by location since the beginning of the year. Here is a screenshot to see what I mean. Please advise how could I better display this in the dashboard. What am I doing wrong here?

Thank you!
