The Symbols section of the Format Graph: Multiple Variables dialog consists of three different pages of options:
•Size
The option to enable - or disable - symbols being plotted on the graph can be controlled by a Show Symbols checkbox at the top of the page. This checkbox control is shared across all of the Symbol pages (in other words, if you uncheck Show Symbols on the Fill Color page, it will also be unchecked on the Size and Border pages).
