Changing the label color on a Pie Chart using System.Web.UI.DataVisualization.Charting namespace


Changing the label color on a Pie Chart using System.Web.UI.DataVisualization.Charting namespace

should help you out Alright, I figured it out. What I had to do was add a series to the XML. To do this I had to know the name of the series and I know that because when I called the AddSeries method on chart2 the first parameter is its name and therefore my series name is Default.
So the next step I took was to add a series open tag and a series end tag before ChartAreas. In between teh series tag I added another series tag that had the Name and LabelForeColor properties like so:
code :
<Series Name=""Default"" LabelForeColor=""#ffffff"" />
@"<Chart ForeColor=""#ffffff"" BackColor=""#0000ff"" BackGradientStyle=""TopBottom"" BackSecondaryColor=""White"" BorderColor=""26, 59, 105"" BorderlineDashStyle=""Solid"" BorderWidth=""2"" Palette=""none"" PaletteCustomColors=""#0000FF; #0055ff; #5599ff;"">
    <Titles>
        <Title ForeColor=""#ffffff"" Name=""main"" Font=""Arial Black, 16pt, style=Bold"" />
    </Titles>
    <Series>
        <Series Name=""Default"" LabelForeColor=""#ffffff"" />
    </Series>
    <ChartAreas>
    //... and so on and so forth

this one helps. I believe it's in the System.Web.DataVisualization DLL.

seems to work fine I'm assuming you have a single chart area that you are adding the series' to? If so, you can modify the maximum value of the Y axis that belongs to that chart area. It would be something like this:
code :
// put this block above your foreach loop
double maxval = 100; // <-- put your maximum value here.
chart.ChartAreas[0].AxisY.Maximum = maxval;
Is there a bug of System.Windows.Forms.DataVisualization.Charting.Chart, when setting chart.ChartAreas[0].Axes[0].Maximu

hop of those help? No, there is no bug in the Chart control; the error is in your logic. You expect the axis to grow but it never needs to grow beyond the maximum of your data. And since your data are limited by the pixel coordinates once you hit the limit the axes will stay where they are.
You also fail to convert the pixel coordinates to the value coordinates of your axes.
code :
private void chart2_MouseMove(object sender, MouseEventArgs e)
{
    Axis ax = chart1.ChartAreas[0].AxisX;
    Axis ay = chart1.ChartAreas[0].AxisY;
    if (e.Button.HasFlag(MouseButtons.Left))  // only draw when the button is pressed
    {
        // convert pixels to values!
        chart1.Series[0].Points.AddXY(ax.PixelPositionToValue(e.X), 
                                      ay.PixelPositionToValue(e.Y));
        if (chart1.Series[0].Points.Count > 200)
        {
            chart1.Series[0].Points.RemoveAt(0);
        }
    }
private void timer1_Tick(object sender, EventArgs e)
{
    Point cp = Control.MousePosition;
    chart1.Series[0].Points.AddXY(cp.X, -cp.Y);
    if (chart1.Series[0].Points.Count > 200)
    {
        chart1.Series[0].Points.RemoveAt(0);
    }
    chart1.ChartAreas[0].RecalculateAxesScale();   // <<-------
}

Any of those help You can control the alignment of the Labels by setting a custom property.
This can be done for the whole Series but also for each DataPoint individually:
code :
Series s = chart1.Series[0];
s.ChartType = SeriesChartType.Column;
s.IsValueShownAsLabel = true;

for (int i = 0; i < 30; i++)
{
    int p = s.Points.AddXY(i, rnd.Next(30));
    DataPoint pt = s.Points[p];
    if (pt.YValues[0] >   10)   // use a suitable value!
    {
       pt.SetCustomProperty("LabelStyle", "Bottom");
       pt.LabelForeColor = Color.White;
    }
    else pt.LabelBackColor = Color.White;

}

Hope that helps I have been analyzing the Microsoft code samples here: Samples Environments for Microsoft Chart Controls. The behavior you wish may be accomplished by either option below:
Using multiple Y axes (screenshot) with realignment of your data. Implies having a copy of you original data points. Then just modify axis properties for your second series. Full code available in the samples. Obviously you have to do that for the X axis. Using primary and secondary axes: AxisX and AxisX2. Using custom labels (screenshot). Code sample available at the link above.
