WPF TChart program hang

[neurosoft]

Hello!

With this segment of code program hanged forever. But if use for tChart.Height another value than 63 it works.
The problem is in method Steema.TeeChart.WPF.Axis.InternalCalcLabelsIncrement() - there is some infinite cycle.

public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();

TChart tChart = new TChart();
Points points = new Points();
tChart.Axes.Left.AutomaticMaximum = false;
tChart.Axes.Left.AutomaticMinimum = false;
tChart.Axes.Left.Logarithmic = true;
tChart.Axes.Left.Maximum = 100;
tChart.Axes.Left.Minimum = 10;
tChart.Series.Add(points);
tChart.Width = 300;
tChart.Height = 63;
Content = tChart;
}

}

Hello neurosoft,

Using next code Xaml:

Code: Select all

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="300" Width="300"
    xmlns:my="clr-namespace:Steema.TeeChart.WPF;assembly=TeeChart.WPF">
    <Grid>
        <my:TChart Margin="0,0,0,0" Name="tChart1" />
    </Grid>
</Window>

And next code:

Code: Select all

  private void InitializeChart()
        {
            tChart1.Aspect.View3D = false;
            Points points = new Points();
            tChart1.Axes.Left.AutomaticMaximum = false;
            tChart1.Axes.Left.AutomaticMinimum = false;
            tChart1.Axes.Left.Logarithmic = true;
            tChart1.Axes.Left.Maximum = 100;
            tChart1.Axes.Left.Minimum = 10;
            tChart1.Series.Add(points);
            tChart1.Width = 300;
            tChart1.Height = 63;
        }

It works as expected to us with last version of TeeChartWPF . Please, could you check again if previous code works for you? And also, you can tell us which version of TeeChartWPF are you using?

Thanks,

Hello neurosoft,

I could reproduce your problem using last version 4.0.2011.2083 of TeeChartWPF but not with source code, so it will be solved in next version of TeeChart.Net. I recommend you to be aware at this forum, our RSS news feed, Steema Software's twitter or facebook accounts for new release announcements and what's implemented on them.

Thanks,

Hello!

I have loaded latest TChart version 4.1.2011.4193 from 19.04.2011, but this problem remained. Please check it!

Hello neurosoft,

You are right. I have added your request in bug list with number [TW16015529]. We will try to fix it in next versions of TeeChart.Net.

Thanks,
