Hello,

I would like to get normal callouts with the web theme.
In the following pictures please ignore the colors which in web theme are horrendous. Please concentrate on just the Marks.

I would like the Marks callout style which is in this chart:

: WithoutWebTheme.PNG (17.86 KiB) Viewed 11269 times

But if I apply the Web theme I get this:

: WithWebTheme.PNG (14.43 KiB) Viewed 11270 times

I used this code to display the two types. (uncomment out the

Code: Select all

// #define USE_WEB_THEME

to change)

Code: Select all

// #define USE_WEB_THEME
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace TestCallouts
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            InitializeChart();
        }

        private void InitializeChart()
        {
            tChart1.Aspect.View3D = true;
            Steema.TeeChart.Styles.Pie TheSeries = new Steema.TeeChart.Styles.Pie();
            TheSeries.FillSampleValues(5);
#if (USE_WEB_THEME)
            Steema.TeeChart.Themes.Theme theme;
            theme = new Steema.TeeChart.Themes.WebTheme(tChart1.Chart);
            theme.Apply();
#endif
            TheSeries.Marks.Visible = true;
            tChart1.Series.Add(TheSeries);
        }
    }
}

So, how do I get back to the normal style of marks callouts when using the web theme?

Also, is there a place that a customer can look to see the difference between(/changes done for each) the themes?

Hello,

If I'm not mistaken, the property you are looking is this one:

Code: Select all

    Pie series;
    private void InitializeChart()
    {
      series = new Pie(tChart1.Chart);
      series.FillSampleValues();

      series.Marks.TailStyle = MarksTail.WithPointer;
    }

I'm afraid there is no available list of properties which are modified for each theme, as the relevant files are only in binary format (*.ten).

Changing the test by adding the code you gave me there is no change in the chart.

Code: Select all

#define USE_WEB_THEME
using Steema.TeeChart.Styles;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace TestCallouts
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            InitializeChart();
        }

        private void InitializeChart()
        {
            tChart1.Aspect.View3D = true;
            Steema.TeeChart.Styles.Pie TheSeries = new Steema.TeeChart.Styles.Pie();
            TheSeries.FillSampleValues(5);
#if (USE_WEB_THEME)
            Steema.TeeChart.Themes.Theme theme;
            theme = new Steema.TeeChart.Themes.WebTheme(tChart1.Chart);
            theme.Apply();
#endif
            TheSeries.Marks.Visible = true;
            TheSeries.Marks.TailStyle = MarksTail.WithPointer;
            tChart1.Series.Add(TheSeries);
        }
    }
}

Let me try and make this a little simpler.

I start with:

: TypeIWant.PNG (1.18 KiB) Viewed 11262 times

I add the "Web" theme and I get:

: TypeIDoNotWant.PNG (1.13 KiB) Viewed 11261 times

How do I get from:

: TypeIDoNotWant.PNG (1.13 KiB) Viewed 11261 times

Back to:

Hello,

With the latest public version TeeChart.dll, the following code:

Code: Select all

    Pie series;
    private void InitializeChart()
    {
      series = new Pie(tChart1.Chart);
      series.FillSampleValues();

      tChart1.CurrentTheme = ThemeType.Web;

      series.Marks.Arrow.Visible = false;
      series.Marks.TailStyle = MarksTail.WithPointer;
    }

gives me this:

: TChart636246912725529894.png (17.74 KiB) Viewed 11243 times

and:

: phones.PNG (10.36 KiB) Viewed 11244 times

Looks like the order was also important. I had in my code:

Code: Select all

            TheSeries.Marks.Arrow.Visible = false;
            TheSeries.Marks.TailStyle = MarksTail.WithPointer;
            tChart1.Series.Add(TheSeries);

And it needed to be:

Code: Select all

            tChart1.Series.Add(TheSeries);
            TheSeries.Marks.Arrow.Visible = false;
            TheSeries.Marks.TailStyle = MarksTail.WithPointer;

Thanks!
