Draw bigger points on a Graph with core plot

Question

In my iOS app I would like to mark special points of a function, like the intersection of the curve with the x and y axis. Is this possible with core plot?

Answer 1

The datasource can provide different plot symbols for each data point using the -symbolForScatterPlot:recordIndex: method. You can also use a second scatter plot with no data line that contains only the points you want to highlight.
