Hello Fulcrum,

I have made a simple code that can help you to achieve as you want:

Code: Select all

          public Form1()
        {
            InitializeComponent();
            InitializeChart();
        }

        Steema.TeeChart.Styles.Bar series1;
        private void InitializeChart()
        {
            tChart1.Walls.Back.Visible = false;
            series1 = new Bar(tChart1.Chart);
            tChart1.Legend.Visible = false; 
            series1.Add(0, 5000);
            series1.Add(1, 95000);
            series1.Add(2, 50000);
            series1.Add(3, 34000);
            series1.Add(4, 68000);
            tChart1.Axes.Bottom.Labels.Items.Clear();
            for (int i = 0; i < series1.Count; i++)
            {
                if (i == 0)
                {
                    tChart1.Axes.Bottom.Labels.Items.Add(series1.XValues[i], "Grava cemento");
                }
                else if (i == 1)
                {
                    tChart1.Axes.Bottom.Labels.Items.Add(series1.XValues[i], "Grava Suelo");
                }
                else if (i == 2)
                {
                    tChart1.Axes.Bottom.Labels.Items.Add(series1.XValues[i], "Zahorra");
                }
                else if (i == 3)
                {
                    tChart1.Axes.Bottom.Labels.Items.Add(series1.XValues[i], "Betunes");

                }
                else if (i == 4)
                {
                    tChart1.Axes.Bottom.Labels.Items.Add(series1.XValues[i], "Mezclas Bifuminosas");
                }
            }
            tChart1.Axes.Bottom.Labels.Angle = 45;
            tChart1.Export.Image.PDF.Save(@"C:\tmp\tchart1.pdf"); 
        }

   
        private void button1_Click(object sender, EventArgs e)
        {
            tChart1.Export.Image.PDF.Save(@"C:\tmp\tchart1.pdf"); 
        }

Could you tell us if previous code works in your end?

Thanks,

[Fulcrum]

Thank for you reoply Sandra but its not working.

in my program i export first the chart to a jpeg:

Code: Select all

 WebChartTripleBarras2.Chart.Export.Image.JPEG.Save("C:\ImagenInformeTripleBarras2.jpeg")

but didnt show all the axis, so i use:

Code: Select all

JpegBarras2.Quality = 100
JpegBarras2.Width = 900 
JpegBarras2.Height = 700

to resize the image.

I hope you could help me

[Sandra]

Hello Fulcrum,

Thanks for information. We would be very grateful if you can arrange for us a simple code, where we can reproduce the problem exactly, because here If I use custom labels, the problem disappears.

Thanks,

[Fulcrum]

Code: Select all

Dim ch3 As Steema.TeeChart.Chart = WebChartTripleBarras3.Chart

Hello Fulcrum,

I have made a simple code, where I am using with custom labels and your problems is solved:

Code: Select all

        Steema.TeeChart.Styles.Bar series1; 
        string [] labelstext; 
        private void InitializeChart()
        {
            WebChart1.Chart.Aspect.View3D = false;
            series1 = new Bar(WebChart1.Chart);
           labelstext = new string[]{"Desmonte Total","Volumen de Vertedero","Rellenos con Mat. Excavacion","Rellenos con Mat. Prestamo",
               "Seleccinado de Excavacion","Selecciondo de Prestamo","Cemento Suelo Estabilizado","Resto de unidades"}; 
            series1.Add(72049.789999999994, "Desmonte Total");
            series1.Add(23371.139999999999, "Volumen de Vertedero");
            series1.Add(71177.119999999995, "Rellenos con Mat. Excavacion");
            series1.Add(91177.119999999995, "Rellenos con Mat. Prestamo");
            series1.Add(53371.139999999999, "Seleccinado de Excavacion");

            WebChart1.Chart.Legend.Shadow.Visible = true;
            WebChart1.Chart.Legend.Visible = false;
            //CUSTOM LABELS
            AddCustomLabels(series1,labelstext);

            WebChart1.Chart.Export.Image.JPEG.Save(@"C:\ImagenInformeTripleBarras3.jpeg");
        }


        protected void AddCustomLabels(Series s, string[] arraylabels)
        {
            WebChart1.Chart.Axes.Bottom.Labels.Items.Clear();
            for (int i = 0; i < series1.Count; i++)
            {

            }

        }

Could you please, check my previous code?

Thanks,

[Fulcrum]

i have converted the code to vb.net and visual studio dont recognize series as a class

Code: Select all

Protected Sub AddCustomLabels(s As Series, arraylabels As String())

I woul like to know another thing, is posible on the y axis mark the label of certain values like every 50.000 for example changing the color or making more extensive the line

Thank you for helping me

[Sandra]

Hello Fulcrum,

I have converted my c# code to vb code and it works in correct way:

Code: Select all

 Private series1 As Steema.TeeChart.Styles.Bar
    Private labelstext As String()
    Public Sub New()

        ' This call is required by the designer.
        InitializeComponent()

        ' Add any initialization after the InitializeComponent() call.

    End Sub
    Private Sub InitializeChart()
       WebChart1.Chart.Aspect.View3D = False
        series1 = New Steema.TeeChart.Styles.Bar(TChart2.Chart)
        labelstext = New String() {"Desmonte Total", "Volumen de Vertedero", "Rellenos con Mat. Excavacion", "Rellenos con Mat. Prestamo", "Seleccinado de Excavacion", "Selecciondo de Prestamo", _
            "Cemento Suelo Estabilizado", "Resto de unidades"}
        series1.Add(72049.79, "Desmonte Total")
        series1.Add(23371.14, "Volumen de Vertedero")
        series1.Add(71177.12, "Rellenos con Mat. Excavacion")

       WebChart1.Chart.Legend.Shadow.Visible = True
       WebChart1.Chart.Legend.Visible = False
        'CUSTOM LABELS
        AddCustomLabels(series1, labelstext)

           WebChart1.Chart.Axes.Bottom.Labels.Items.Add(s.XValues(i), arraylabels(i))
        Next

    End Sub

Could you tell us if previous code works in your end?

Thanks,

[Fulcrum]

I have tried your solution but now the chart in the webpage dont have all the labels in the axis

[Sandra]

Hello Fulcrum,

Using my previous code with last version of TeeChart 2012:

Code: Select all

Private series1 As Steema.TeeChart.Styles.Bar
    Private labelstext As String()
    Public Sub New()

        ' This call is required by the designer.
        InitializeComponent()
        InitializeChart()
        ' Add any initialization after the InitializeComponent() call.
    End Sub
    Private Sub InitializeChart()
       WebChart1.Chart.Aspect.View3D = False
        series1 = New Steema.TeeChart.Styles.Bar(TChart2.Chart)
        labelstext = New String() {"Desmonte Total", "Volumen de Vertedero", "Rellenos con Mat. Excavacion", "Rellenos con Mat. Prestamo", "Seleccinado de Excavacion", "Selecciondo de Prestamo", _
            "Cemento Suelo Estabilizado", "Resto de unidades"}
        series1.Add(72049.79, "Desmonte Total")
        series1.Add(23371.14, "Volumen de Vertedero")
        series1.Add(71177.12, "Rellenos con Mat. Excavacion")
        series1.Add(91177.12, "Rellenos con Mat. Prestamo")
        series1.Add(53371.14, "Seleccinado de Excavacion")
        series1.Add(1177.11999999999, "Selecciondo de Prestamo")
        series1.Add(0, "Cemento Suelo Estabilizado")
        series1.Add(11177.12, "Resto de unidades")
        series1.Marks.Visible = False
        WebChart1.Chart.Legend.Shadow.Visible = True
        WebChart1.Chart.Legend.Visible = False
        'CUSTOM LABELS
        AddCustomLabels(series1, labelstext)

        WebChart1.Chart.Axes.Bottom.Labels.Angle = 50
       WebChart1.Chart.Export.Image.JPEG.Quality = 100
       WebChart1.Chart.Export.Image.JPEG.Width = 2000
       WebChart1.Chart.Export.Image.JPEG.Height = 900
       WebChart1.Chart.Export.Image.JPEG.Save("C:\ImagenInformeTripleBarras3.jpeg")
    End Sub

    Protected Sub AddCustomLabels(s As Steema.TeeChart.Styles.Series, arraylabels As String())
       WebChart1.Chart.Axes.Bottom.Labels.Items.Clear()
        For i As Integer = 0 To series1.Count - 1
           WebChart1.Chart.Axes.Bottom.Labels.Items.Add(s.XValues(i), arraylabels(i))
        Next

    End Sub

I have achieved next result in the browser:

ChartinBrowser.jpg (86.31 KiB) Viewed 15912 times

I have gotten next image using your indications to export the chart:

ImagenInformeTripleBarras3.jpeg (333.64 KiB) Viewed 15910 times

I consider the results are correct. For this reason,I would be very grateful if you can indicate us, if the problem appears in my attached images. If it doesn't appear, please try to modify the code, so we can reproduce your problem here. On the other hand, could you please tell us which version of TeeChart are you using in this moment?

Thanks,

[Fulcrum]

yes the problema is in the second chart and in my intructions for saving the chart.
In my web the chart dont have all the axis


so to make then to appear I have to make the image larger

Now I havee notice something in your code that i didnt do when I tried it

Code: Select all

series1 = New Steema.TeeChart.Styles.Bar(TChart2.Chart)

when you define series1 you use TChart2, how do you define it. I defined it like the chart I was using and that could be my mistake.
Do I have to define a second chart?

[Sandra]

Hello Fulcrum,

I have attached my project where your problem doesn't appear using latest versions of TeeChartFor.Net (4.1.2012.01312). For this reason, we would be very grateful if you can check my attached project and inform us of results you get.
On the other hand, could you confirm us which version are you using?

Now I havee notice something in your code that i didnt do when I tried it

Sorry, I have forgotten to remove this line of code, isn't necessary.

Hello Sandra and thank you, your projects Works fine and I have fixed the problema but when i tried in this one dont seem it solves anything.

Hello Fulcrum,

I have modified a little your code and using it but my AddCustomLabels method, your code works in correct way:

Code: Select all

       Private series1 As Steema.TeeChart.Styles.Bar
    Private labelstext As String()
    Private ch1 As Steema.TeeChart.Chart
    Private Sub InitializeChart()
        ch1 = WebChart1.Chart()
        labelstext = New String() {"Hormigon", "Acero Estructural", "Acero con Arma. Pasivas", "Acero en Pretensados"}
        Dim SeriesBar1 As New Steema.TeeChart.Styles.Bar(ch1)
        SeriesBar1.Add(72049.79, "Hormigon")
        SeriesBar1.Add(23371.14, "Acero Estructural")
        SeriesBar1.Add(71177.12, "Acero con Arma. Pasivas")
        SeriesBar1.Add(91177.12, "Acero en Pretensados")
        SeriesBar1.Marks.Visible = False
        ch1.Legend.Visible = False
        ch1.Series(0).ShowInLegend = False
        ch1.Walls.Back.Gradient.Visible = False
        ch1.Walls.Back.Color = Color.White
        ch1.Panel.Gradient.Visible = False
        ch1.Panel.Color = Color.White
        ch1.Axes.Bottom.Labels.Angle = 30
        SeriesBar1.Color = Color.Blue
        SeriesBar1.Gradient.StartColor = Color.RoyalBlue
        SeriesBar1.Gradient.MiddleColor = Color.DodgerBlue
        SeriesBar1.Gradient.EndColor = Color.DeepSkyBlue
        SeriesBar1.Gradient.UseMiddle = True
        SeriesBar1.Gradient.Visible = True
        SeriesBar1.BarStyle = Steema.TeeChart.Styles.BarStyles.RectGradient
        AddCustomLabels(SeriesBar1, labelstext)

        ch1.Panel.Bevel.Outer = Steema.TeeChart.Drawing.BevelStyles.None
        Dim JpegBarras1 As Steema.TeeChart.Export.JPEGFormat = ch1.Export.Image.JPEG
        JpegBarras1.Quality = 100
        JpegBarras1.Width = 900 'm_PictureBox.Width
        JpegBarras1.Height = 700 'm_PictureBox.Height
        WebChart1.Chart.Export.Image.JPEG.Save("C:\ImagenInformeTripleBarras1Final.jpeg")
    End Sub

    Protected Sub AddCustomLabels(ByVal s As Steema.TeeChart.Styles.Series, ByVal arraylabels As String())
        ch1.Chart.Axes.Bottom.Labels.Items.Clear()
        For i As Integer = 0 To s.Count - 1
            ch1.Chart.Axes.Bottom.Labels.Items.Add(s.XValues(i), arraylabels(i))
        Next
    End Sub

I have made the test in VS2008 and latest version of TeeChartFor.Net. Do you use last version of TeeChartFor.Net?

Thanks,

[Fulcrum]

Thank you for everything Sandra, the problema is finally solved
