Some question about charting

[Michele]

Hello,
Please excuse if I continue writing on the forum, but I'm new to reporting and I found it not so natural ...
Here're my lastest problem :

• How do I add on Y Axes a description? I've got 11 items, 1,2,3,4,5,6,7,8,9,10,11 I would like to see "Class 1","Class 2" ....
• The Y items are sorted in the chart strarting from 1 in the square of the bar chart going to 11 on top, how can I reverse them? I've tried sorting the collection by code, but no luck
• I've set on X asses a Stepping of 20, on range 0-100 but I see a 10 stepping...why?

Thanks in advance

Hi Paolo,

Onto your questions:

• We suppose you are using horizontal orientation for your chart and you would like to add description for the vertical axis (in this case this is the XAxis) -- you can customize the axis labels like this:

private void chart1_NeedDataSource(object sender, EventArgs e)
{
    ChartSeries series = new ChartSeries();
    series.AddItem(10);
    series.AddItem(20);
    series.AddItem(30);
    series.AddItem(40);

    chart1.Series.Add(series);

    chart1.PlotArea.XAxis.AutoScale = false;
    chart1.PlotArea.XAxis.AddRange(1, series.Items.Count, 1);

    for (int i = 0; i < chart1.PlotArea.XAxis.Items.Count; i++)
    {
        ChartAxisItem axisItem = chart1.PlotArea.XAxis.Items[i];
        axisItem.TextBlock.Text = "Class " + i;
    }
}

• RadChart does not provide support for reversing the order of the series items -- you will need to modify your data and pass it in reverse order to achieve the desired functionality.

• Make sure you are setting the Axis.AutoScale property to false as otherwise you cannot customize the axis range manually.

Hey.

RadChart does not provide support for reversing the order of the series items -- you will need to modify your data and pass it in reverse order to achieve the desired functionality.

Can you please provide a example how to do this?

Cheers

Hello Jaimie,

I believe in terms of Manuel's example it should look like this:

ChartSeries series = new ChartSeries();
series.AddItem(40);
series.AddItem(30);
series.AddItem(20);
series.AddItem(10);

that is... send the items to the chart in reverse order, so that the first item (in this example -- 10) is added last so it appears at the top.
