Hide specific legend not all

[zohaibbrohi]

I have a graph with 3 different values.
I have 3 legends but I want to hide 1 legend. Is it possible
For hiding all I can use legend.enable = false. But I want to hide it when setting LineChartDataSet.
In this picture I have 2 legend. One with text speed and other without text. I want to disable the dot as well.

you need to override the legend renderer e.g.

open func renderLegend(context: CGContext)

to ignore certain values
