You can change the colors used by the boxplot, provided that you execute this code after the data has been passed to the chart and the chart has been set to use boxplot
int index = stats.Gallery.BoxPlot.ShowOutliers ? 2 : 1;
chart1.Series[index + 1].Color = Color.LightGray;
chart1.Series[index + 1].Border.Color = Color.Black;
chart1.Series[index + 2].Color = Color.LightGray;
chart1.Series[index + 2].Border.Color = Color.Black;
chart1.Series[index].Color = Color.Black;
chart1.Series[index+3].Color = Color.Black;
Please note that indices are different depending on whether you are showing Outliers or not.
We will be uploading a hotfix for the ignored BoxPlot.Monochrome property in a couple of days, please note that even after installing the hotfix, you will need code to set the colors you want to use, as Monochrome will mean we share the attributes between the upper and lower whiskers and the upper and lower box, so with the hotfix you would need something like
stats.Gallery.BoxPlot.Monochrome = true;
chart1.Series[0].Color = Color.LightGray;
chart1.Series[0].Border.Color = Color.Black;
chart1.Series[3].Color = Color.Black;
To download a hotfix you will need to have a valid StudioFX subscription and visit https://www.mysoftwarefx.com/hotfix, you can also post your questions/issues at https://www.mysoftwarefx.com/support.
The hotfixes also include new functionality, e.g. we recently added a boolean ShowMedian property to BoxPlot.
