Chart properties can be configured by clicking on the chart properties button. The properties are used to further customize how information is displayed. As a new study is added, the properties of that study are also added to the chart properties area. The same properties can be chosen by right clicking on the chart.
Click the Properties button in the upper left corner of the Chart to open the Chart Properties.
Helpful Hint: You can also right click from within the chart to bring up a menu that will allow you to select the properties as well.
