Hi Sigfredo,
Yes you can import a double array to a stacked bar but it largely depends how the values in the array must be treated. The following code shows how to create a stacked bar chart from a double array where half of the values go into the first bar and the rest into the second:
NChart chart = nChartControl1.Charts[0];
double[] values = new double[] { 10, 20, 30, 10, 20, 30 };
NBarSeries bar1 = new NBarSeries();
int i = 0;
for (; i < values.Length / 2; i++)
{
bar1.Values.Add(values[i]);
}
chart.Series.Add(bar1);
NBarSeries bar2 = new NBarSeries();
bar2.MultiBarMode = MultiBarMode.Stacked;
for (; i < values.Length; i++)
{
bar2.Values.Add(values[i]);
}
chart.Series.Add(bar2);
Hope this helps - let us know if you have any questions.
