another, hopefully simple one -- is there a way to combine color and type (for example) in the legends? Currently for a line graph if i do
```            color("Metric")
            type( "Metric")```
... i get 2 separate legends, one showing colours and the other line types (in this particular case, "Metric" only ever has 2 values, and in reality, i use `categorical` to determine which one gets a dashed line, whereas i currently keep the default colour mappings... while i can turn off the legend for line types, the one remaining for colours is useful, but looks wrong since the "blue" line appears solid in the legend)

Hi! Could you please share your code?
This should work by default:

thanks <@U03A1943BPG> -- here's what i currently do
```
val dirPlot = allData
    .select("Period", "Unfiltered", "Filtered")
    .gather("Unfiltered", "Filtered").into("Metric", "Value")
    .plot {
        layoutWithHorizontalTopLeftLegend("My title")()
        line {
            x("Period"){
                axis.name = ""
            }
            y("Value") {
                axis.name = "%"
                scale = continuous(0..100)
            }
            color("Metric") {
                legend.name = "" // The legend title is the column name by default, which isn't useful here ("Metric")
            }
            type( "Metric") {
                scale = categorical("Unfiltered" to LineType.DASHED, "Filtered" to LineType.SOLID)
                legend {
                    type = LegendType.None
                }
            }
            tooltips(enable = true)
        }
    }```

right, so i remove legend.name from color{}, then it works as your example, but i can't see how/where to remove the legend title

Looks like you need to remove legend name for both aesthetics:

Try this instead of not displaying `type` legend.

i accidentally just found out I can also do
```    layout {
        style {
            legend {
                title {
                    blank = true
...```
which leaves the plots a little cleaner (i'm reusing a function for layouts across several plots) but of course only makes sense if i can dispense of _all_ legend titles in the given plot

the next thing i'd love for legends is the ability to have _no_ background (or transparent with an alpha level) -- or better yet, have a "smart" positioning system that positions the legend wherever it doesn't overlap with the plot (of course i could also just leave them _outside_ the plot but i'm tight on space so i'd rather maximise the space used by the plot itself)
