Description Shinobu Nagai 2014-01-30 20:01:15 EST

Please see the attached image.

The upper charts show the result in a user's tested environment, and the lower charts are the ones in his deployment environment.

1. If he sets the Legend.Transparency, it's also applied to the legend texts:
In v4.1.2012.1311, Transparency was applied to the background of the legend only. 
In v4.1.2013.11081, however, it's applied to entire legend. 

I also attach the sample project to reproduce them at your end. Please add the reference again and rebuild the project.

2. If changing Y axis labels, the labels and title aren't displayed correctly:
In v4.1.2012.1311, if Y axis labels were changed, the chart was automatically redrawn to fit everything inside of the chart area.
In v4.1.2013.11081, however, if Y axis labels are changed, the chart wasn't automatically redrawn, and Y axis labels are overlapped with Y axis title in his tested environment. 
In his deployment environment, Y axis title was shifted outside of the screen and wasn't displayed.
Anyway, they aren't displayed correctly.

Screencap of the TeeChart.WPF

Comment 6 christopher ireland 2014-05-27 06:50:20 EDT

I'm using TeeChart.WPF.dll v.4.1.2014.5094 and the following code:

    private void InitializeChart()
    {
      tChart1.Series.Add(new Bar()).FillSampleValues();

      tChart1.Legend.CustomPosition = true;
      tChart1.Legend.Left = 100;
      tChart1.Legend.Color = Colors.Transparent;

      tChart1.Axes.Left.Title.Text = "Left Axis Title";
      tChart1.Axes.Left.Title.Angle = 90;
    }

This code gives me the Chart shown in this screenshot:
http://bugs.teechart.net/attachment.cgi?id=211

As you can see:
1) The axis title is being rendered correctly
2) The Legend.Color can be set to Colors.Transparent giving the desired transparent effect.

The Legend.Transparency property was changed by design to affect the entirety of the Legend object and not just its background.

overlapped axis label and title when there is no data

Comment 8 Shinobu Nagai 2014-06-03 21:30:31 EDT

Regarding the issue2:
> 2. If changing Y axis labels, the labels and title aren't displayed correctly:

This user checked it with v4.1.2014.02241. Please see the attached image. As you see, y axis label "0" and y axis title didn't overlapped with each other in the previous version. 
Whereas with vv4.1.2014.02241, they overlap with eachother.

To reproduce it, please set the following code to a new project and run it.

private void Form1_Load(object sender, EventArgs e)  {
     tChart1.Chart.Series.Add(new Steema.TeeChart.Styles.Line());

     tChart1.Chart.Axes.Left.Title.Text = "ABCDEFGHIJK";
     tChart1.Chart.Axes.Left.Title.Visible = true;  }

When there is no data, y axis label "0" and y axis title are overlapped. In case of adding some data, it doesn't occur. This user wants to display axis scale (axis, ticks, labels, title, etc.) even before adding data.

issue2 is a duplicate of http://bugs.teechart.net/show_bug.cgi?id=778 which has already been fixed (there's a temporary workaround in the bug report of id=778).
