Tooltips bug

[AndreiKingsley]

Tooltips for columns that mapped on x and y are displayed incorrectly

[alshan]

Taking in account that mapping y = "b" is ignored (unless stat=identity), this is likely an expected behavior.
@AndreiKingsley, what were you expecting in the tooltip?

Column names ("a", "b) on the left side of tooltips, just like for "c".

[alshan]

I see, at first I thought your complain is about tooltip showing "c: a1" instead of "c: b2" :)

Macro '@' substituted with a default title for given aesthetic, which is <empty> for 'positional' aesthetics x/y.
@OLarionova-HORIS am I correct?

[AndreiKingsley]

But why is it empty?

[AndreiKingsley]

Is there any sense in this behavior?

Yes, we don't show the default title for positional variables.
But it's possible to specify the title explicitly: .line("title for a|@a").line("title for b|@b")

[alshan]

May be we can invert this situation and for the setting .line("@|@a") render the tooltip line as

title value

unconditionally?
And let the user to remove the title if necessary using .line("|@a") ?

Seems great!

[OLarionova-HORIS]

So the expected behaviour should be the following:

• .line(@|^aesName).line(@|@varName) => always "title value"
• .line(|^aesName).line(|@varName) => always "value"

But what about titles for positionals x/y in the following situations:

• without specified tooltips
• tooltips are set via variable list: layerTooltips( "a", "b" )

Now we use empty titles for them.

[alshan]

without specified tooltips
tooltips are set via variable list: layerTooltips( "a", "b" )

I think, in the case of multiline tooltip it's preferable to show title regardless of the kind of the aesthetic.

[alshan]

tooltips are set via variable list: layerTooltips( "a", "b" )

Another way to look at it:

layerTooltips( "a", "b" )

is equivalent to

layerTooltips()
  .line("@|@a")
  .line("@|@b")

Fixed in LPK v4.4.0
