 bar chart statistiscs |

Hello,
i have a bar chart that represents an histogram with a distribution that is almost a gaussian type;
i was wondering if chartdirector provides methods to return values for mean, sigma etc, so, in general,
statistics info or i have to calculate them myself.
Thank you very much for some feedback, best regards

Hi Margherita,
You may use ArrayMath.avg to obtain the average value of a sequence of numbers, and ArrayMath.stdDev to obtain its standard deviation. For example, in C#/Java:
ArrayMath m = new ArrayMath(myData);
double mean = m.avg();
double sigma = m.stdDev();
Hope this can help.
Regards
Peter Kwan |
