hello greetings of the day !

I am using a IGChartView to plot chart with four different IGLineSeries. Graph draws perfectly.

However i have an issue with chart legends. I have four line series and so that legend displays four different category of line series.

Now i want remove two lines and its titles from legend.

Please refer attached image.

i want to just display McK&OCS line and Cd&Mck line in legend and want to remove 45 days and 120 days line from legend. As of now i am not using delegate method for chart legend. So is it possible to remove without using delegate method of legend?

Please give me some suggestion.

Thanks.
