I have many series in my chart control. When the program is first loaded, I can see them all at once, when I click on the checkboxes in Legend, they disappear. However, I want all of them to be unchecked when first opened (not visible), but let the user open what they want to see.
If I set visible to false from the settings (even if "Show in Legend" is on). The serial disappears from everywhere and the user cannot open it again.
