On the "Options" dialog, select "Charts" and then "Vector Chart Display" under that.
Select either "Standard" or "Mariner's Standard" for "Display Category".
Make sure "De-Cluttered Text" is checked.
There are many option you can separately enable/disable along the right side of this screen
, so you can play with those options as well (and they may be affecting your current
display already, so maybe switch between categories and apply the changes once to reset those options).
Raster charts are a single
image blob. Nothing is optional within the chart, so there should be no surprises that, so long as you can see a raster chart, any specific datum is present, while vector charts are a series of discrete items all of which have to be separately drawn and so can be enabled or disabled.
