Scale And Marks

[mikethelad]

On the sample graph I have set the scale to 0 to 100, by

WebChart1.Chart.Axes.Left.SetMinMax(0,100);

I want it be in qty's of 10 and not 5, ie 10,20,30 etc

Also

I wish to show the marks as values an not as per the bottom axis label, data is being added like:-

footer = mnth + "_" + year + "\n(n=" + totaln + ")";
line1.Add(7, footer);

Hi mikethelad,

I want it be in qty's of 10 and not 5, ie 10,20,30 etc

You should set Increment property then:

Code: Select all

      tChart1.Axes.Bottom.Increment = 10;

I wish to show the marks as values an not as per the bottom axis label, data is being added like:-

You can set Label.Style like this:

Code: Select all

      tChart1.Axes.Bottom.Labels.Style = Steema.TeeChart.AxisLabelStyle.Value;

For further information about axis settings please read tutorial 4. Tutorials can be found at TeeChart's program group.

Hi, scale change works fine. The axis label, is correct how I have it, I want the mark on the line to show the value

Hi mikethelad,

I want the mark on the line to show the value

Sorry, I understood you wanted the values as bottom axis labels. In that case what you need to change is Marks.Style:

Code: Select all

      tChart1[0].Marks.Style = Steema.TeeChart.Styles.MarksStyles.Value;

Thanks, that works, see new graph, is there anyway to overcome the following:-

1. Overlap of the marks?

2. How to show the % symbol after the mark value

3. 1st and last one not showing

Hi mikethelad,

1. Overlap of the marks?

Yes, you can do something similar as in the example Pep posted here.

2. How to show the % symbol after the mark value

Either using one of the percent related MarksStyles values or manually adding it to the mark text with the GetSeriesMark event:

Code: Select all

    void Form1_GetSeriesMark(Steema.TeeChart.Styles.Series series, Steema.TeeChart.Styles.GetSeriesMarkEventArgs e)
    {
      e.MarkText += "%";
    }

3. 1st and last one not showing

Using MinimumOffset and MaximumOffset, for example:

Code: Select all

      tChart1.Axes.Bottom.MinimumOffset = 5;
      tChart1.Axes.Bottom.MaximumOffset = 5;

What calls the GetSeriesMark event, have tried in the afterdraw but no lucj

Hi mikethelad,

Series call it. You have to subscribe the series to this event.

Sorry don't understand how to :-

"Series call it. You have to subscribe the series to this event."

Hello mikethelad,

You must subscribe and call the GetSeriesMark event when you initialize chart. You can do something next:

Code: Select all

...
 tChart1.Axes.Bottom.Labels.Style = Steema.TeeChart.AxisLabelStyle.Value;
            line1.GetSeriesMark += new Series.GetSeriesMarkEventHandler(series_GetSeriesMark);
            line2.GetSeriesMark +=new Series.GetSeriesMarkEventHandler(series_GetSeriesMark);
            line3.GetSeriesMark +=new Series.GetSeriesMarkEventHandler(series_GetSeriesMark);
        }

        void series_GetSeriesMark(Series series, GetSeriesMarkEventArgs e)
        {
            if (tChart1.Series.IndexOf(series) == 0)
            {
                e.MarkText = series.XValues[e.ValueIndex].ToString() + " %";

            }
            else if (tChart1.Series.IndexOf(series)==1)
            {
                e.MarkText = series.XValues[e.ValueIndex].ToString() + " %";
            }
            else if (tChart1.Series.IndexOf(series) == 2)
            {
                e.MarkText = series.XValues[e.ValueIndex].ToString() + " %";
            }
        }

As you see, in previous code, I have subscribed and called the event for each series in the initialization of chart and it works fine for me. I recommend you always call the event in the initialization of Chart to avoid problems.

Thanks,

Thanks, the following has worked:-

line1.GetSeriesMark += new Steema.TeeChart.Styles.Series.GetSeriesMarkEventHandler(line_GetSeriesMark);

Hello mikethelad,

I am glad that your problem solved.

Thanks,
