Hey, this is a bit different than you’re used to. The way to get the extra axes to show up and use them for plots is to set something called a plot corner. Add your plots to the chart as usual and then call
chart->SetPlotCorner(plot, 1);
The default plot corner is 0, which uses the left and bottom axes. 1 uses bottom and right; 2 uses right and top and 3 uses top and left. I feel like this should have enum types.
