Unfortunately you are misunderstanding the legend creation process. You are 'stylizing' a line (or a polygon) and that's why you are displaying a 'series of P's. Instead of a line or polygon, you should be 'stylizing' a point.
This is how to create a legend .
Create a symbol from a POINT SHAPEFILE. (Reminder: a shapefile is vector. There are exactly three types of vectors: 1.point, 2.line, or 3.polygon. The symbol shown below is a point and has been 'styled' in the Style Editor. The source or the shapefile's name is Surv_Pnts. See image-1.
1-Select shapefile in Task Pane to activate the Style Editor then create your symbol.
Next, create the legend table. Go to your paperspace layout tab=>Layout Tools Tab=>Layout Elements Panel=>Legend Icon. See image-2.
2-The Legend Table is created from your layout tab (paperspace).
Finally, change the default legend Properties, e.g. items to include in legend, title, descriptions, font height. To edit the defaults, hover cursor on edge of legend=>tool wrench with dropdown arrow appears near upper right corner of table=>click the dropdown arrow=>select Properties from shortcut. see image-3.
3-Hover cursor at edge then click dropdown arrow to access legend Properties.
NOTE: If you do not have a point shapefile for your parking locations then you cannot use this method. If you still want to use this method anyway, then you'll need to create a point shapefile from scratch or have someone else create it for you.
