Windows Phone 7.1 Chart questions

[Test123]

Hi,
I am a experimenting your tool with windows phone 7.1.
Sorry about too many questions below,

(a) I would like to know how can i remove gaps between bars,
I am trying to display each day of month and the amount for the day; hence the space between bars is a lost asset for me. please help.
(b) How can I show the axis labels on top of the chart instead of bottom?
     I plan to use only portrait layout.
(c) Can I disable labels altogether and just use trackball (I haven't experimented with it yet) to show labels (for both x and y axis) or details?

Code is similar to your documentation:

            <chart:RadCartesianChart x:Name="chart">
                <chart:RadCartesianChart.HorizontalAxis>
                    <chart:DateTimeCategoricalAxis LabelFitMode="MultiLine"
                                                   LabelFormat="dd"
                                   DateTimeComponent="Day"/>
                </chart:RadCartesianChart.HorizontalAxis>
                <chart:RadCartesianChart.VerticalAxis>
                    <chart:LinearAxis/>
                </chart:RadCartesianChart.VerticalAxis>
                <chart:RadCartesianChart.Series>
                    <chart:BarSeries/>
                    <chart:BarSeries/>
                </chart:RadCartesianChart.Series>
            </chart:RadCartesianChart>

            DateTime lastDate = DateTime.Now;
            int monthnum = DateTime.Now.Month;
            double lastVal = 20;
            List<ChartDataObject> dataSouce = new List<ChartDataObject>();
            for (int i = 0; lastDate.Month == monthnum;  ++i)
            {
                ChartDataObject obj = new ChartDataObject
                {
                    Date =lastDate.Day,
                    Value = lastVal++
                };
                dataSouce.Add(obj);
                lastDate = lastDate.AddDays(1);
            }
            BarSeries series = (BarSeries)this.chart.Series[0];
            series.CategoryBinding = new PropertyNameDataPointBinding()
            {
                PropertyName =
                    "Date"
            };
            series.ValueBinding = new PropertyNameDataPointBinding()
            {
                PropertyName =
                    "Value"
            };
            series.ItemsSource = dataSouce;
            series.CombineMode.Equals("Stack");

/*            lastDate = DateTime.Now;
            lastVal = 40; 
            List<ChartDataObject> dataSouce2 = new List<ChartDataObject>();
            for (int i = 0; lastDate.Month == monthnum; ++i)
            {
                ChartDataObject obj = new ChartDataObject
                {
                    Date = lastDate.Day,
                    Value = lastVal++
                };
                dataSouce2.Add(obj);
                lastDate = lastDate.AddDays(1);
            }
*/

/*            BarSeries series2 = (BarSeries)this.chart.Series[1];
            series2.CategoryBinding = new PropertyNameDataPointBinding()
            {
                PropertyName =
                    "Date"
            };
            series2.ValueBinding = new PropertyNameDataPointBinding()
            {
                PropertyName =
                    "Value"
            };
            series2.ItemsSource = dataSouce2;
            series2.CombineMode.Equals("Stack");

Hi,

Thanks for the questions.
The feature from (a) can be enabled via the GapLength property of the categorical axis. For example:

<telerikChart:CategoricalAxis GapLength="0"/>

(b) is not currently supported but we will consider implementing it in a future release.

You can hide the labels by setting a template that does not display anything. For example:

<telerikChart:LinearAxis>
    <telerikChart:LinearAxis.LabelTemplate>
        <DataTemplate>
            <TextBlock/>
        </DataTemplate>
    </telerikChart:LinearAxis.LabelTemplate>
</telerikChart:LinearAxis>

Finally, yes, you can use the trackball to display any information about a data point. You can find information
on how to use the trackball here.

Please write again if you have other questions.
All the best,
Victor
