Paddings do not work as expected after updating from 515 to 619 - Bug?

[DGPunkt]

Hello,

after having some trouble with RadChart until version 4.x, we just updated from "RadControls for ASP.NET AJAX 2008 1 515" to new "RadControls for ASP.NET AJAX 2008 1 619".

Here is our scenario:

RadChart (IntelligentLabelsEnabled = false -> http://www.telerik.com/community/forums/thread/b311D-begact.aspx#568759 ) with 2 ChartSeries of type Bar. ChartSeriesItem-Labels are visible and rotated by -90. In 515 all item labels at least had a small distance (about 5 px or so) to the plotareas border (top, bottom), depending on the length of the label´s text. In 619 all (long text) item labels just end at the border of the plotarea.

So I tried to work with margins and paddings (in 619), but paddings just do the opposite of what I want - in case of specifiing negative values you get funny results, too. Setting margins just had no visible effect. So I tried and tried, getting angry about that and tried to set margins in 515, where it worked as expected - So I think, it´s just a bug.

Hi DGPunkt,

Have you tried setting the margin values like this (it worked in our local test with the latest version of the control):

protected void PrepareChart1(RadChart chart)
{
    chart.PlotArea.XAxis.Appearance.LabelAppearance.Visible = false;
    chart.PlotArea.YAxis.Appearance.ValueFormat = ChartValueFormat.Currency;

    ChartSeries dep1Series = new ChartSeries();
    dep1Series.Type = ChartSeriesType.Bar;
    dep1Series.Name = "Department 1";

    dep1Series.AddItem(100000, "Company 1: 100.000");
    dep1Series.AddItem(150000, "Company 2: 150.000");
    dep1Series.AddItem(125000, "Company 3: 125.000");
    dep1Series.AddItem(140000, "Company 4: 140.000");
    dep1Series.AddItem(110000, "Company 5: 110.000");



    ChartSeries dep2Series = new ChartSeries();
    dep2Series.Type = ChartSeriesType.Bar;
    dep2Series.Name = "Department 2";

    dep2Series.AddItem(140000, "Company 6: 140.000");
    dep2Series.AddItem(110000, "Company 7: 110.000");
    dep2Series.AddItem(100000, "Company 8: 100.000");
    dep2Series.AddItem(150000, "Company 9: 150.000");
    dep2Series.AddItem(125000, "Company 10: 125.000");

    chart.AddChartSeries(dep1Series);
    chart.AddChartSeries(dep2Series);

    dep1Series.Appearance.LabelAppearance.RotationAngle = -90;
    dep2Series.Appearance.LabelAppearance.RotationAngle = -90;

    dep1Series.Appearance.TextAppearance.Dimensions.Margins.Right = Telerik.Charting.Styles.Unit.Pixel(40);
    dep2Series.Appearance.TextAppearance.Dimensions.Margins.Right = Telerik.Charting.Styles.Unit.Pixel(40);
}

Hi Manuel,

yes, interesting, that works, but it is not really satisfiing my needs:

I need to set margins for top and bottom (rotation = -90, so right AND left), because I also have negative values shown close to the bottom line. And if I set margins for both (right and left) it has no visible effect anymore as described in my first post.

dep1Series.Appearance.TextAppearance.Dimensions.Margins.Right = Telerik.Charting.Styles.Unit.Pixel(40); 
dep1Series.Appearance.TextAppearance.Dimensions.Margins.Left = 

Telerik.Charting.Styles.Unit.Pixel(40);

Hello DGPunkt,

Indeed it seems setting the left margin does not work as expected here -- we will forward your feedback to our developers so they can correct the behavior and optionally restore the behavior from the old version so there is no need to manually set the margin values.

We have updated your Telerik points for the report. For the time being if you would like to have some margin value, we would suggest you to rotate the labels to another angle like -45 degrees and not apply the margins.

Sorry for the temporary inconvenience.


Kind regards,
Manuel
