Hello,
I have a question, if I don't set the property of axisY, the default value of AutoRange is 'true' .
Like following example, First I add some plus value to the dataseries , and then I add some minus value to the dataseries.
After that the chart crashes, it just can't show the points I add.
Can you help me to solve the problem? Thank you!
for (int i = 0; i < 6; i++)
{
ChartArea.DataSeries.First().Add(new DataPoint(i, 0.01 * i));
}
for (int i = 6; i < 10; i++)
{
ChartArea.DataSeries.First().Add(new DataPoint(i, -0.01 * i));
}

Dim myDataTable As New DataTable
myDataTable = GetDataTable() 'returns datatable with multiple rows
Me.myRadCarousel.ItemsSource = myDataTable
However, the carousel shows blank images, even though they exist. I double-click on the carousel to get the file name and I get the file name no issue. my datatable contains 1 field (filename)
