[X-axis labelling with curve and line]

hi,

I have already set "AxisX.step" to 1 and I have the same issue but this one only appears with curve and line. I have good results with bar,bubble....

Chart.AxisX.Step = 1;Chart.AxisX.Staggered = true;

Chart.DataSource = points;

 

 

[X-axis labelling with curve and line]

Hi,

I use integer values for the X-axis and when I choose a line or a curve chart I don't have X-Axis labels well-displayed (see file attached). If values on this axis are "string" or "datetime" Labels are well displayed

my code is:

Chart.Data.Clear();

Chart.DataSourceSettings.Fields.Clear();

Chart.DataSourceSettings.Fields.Add(new FieldMap(points.Columns[0].ColumnName, FieldUsage.XValue));

for (int i = 1; i < points.Columns.Count; ++i)

{

Chart.DataSourceSettings.Fields.Add(new FieldMap(points.Columns.ColumnName, ChartFX.WinForms.FieldUsage.Value));

Chart.DataSourceSettings.Fields.DisplayName = points.Columns.Caption;

}

Chart.AxisX.Step = 1;Chart.AxisX.Staggered = true;

Chart.DataSource = points;

Thank you

 

[X-Axis labelling with datetime]

Hi,

I have Datetime values on the X-Axis and not all labels are displayed (see file attached).

My code:

chart.Data.Clear();

chart.DataSourceSettings.Fields.Clear();

Type type = points.Columns[0].DataType;

if (type == typeof(decimal) || type.IsPrimitive || type == typeof(DateTime)) // type = Datetimechart.DataSourceSettings.Fields.Add(new FieldMap(points.Columns[0].Caption, FieldUsage.XValue));

elsechart.DataSourceSettings.Fields.Add(new FieldMap(points.Columns[0].Caption, FieldUsage.Label));

for (int i = 1; i < points.Columns.Count; ++i)chart.DataSourceSettings.Fields.Add(new FieldMap(points.Columns.Caption, ChartFX.WinForms.FieldUsage.Value));

 

chart.AxisX.LabelsFormat.Format = AxisFormat.Date;

chart.DataSource = points;

 

Sincerely

[Business Object with a generic class]

Hi,

For my business Object I use a class which implements this interface:

public interface IGraphPoint<T1,T2>

{

string SerieName { get; }

T1 XValue {

get; }T2 YValue { get ; }

}

So I created a class Point which implements IGraphPoint :

public

class Point : IGraphPoint<double, double>

{ /* Implementation */ }

and I initialise my chart using listDataProvider and CrossTabDataProvider:

ListProvider l = new ListProvider(pointsList); // pointsList = List<Point>

CrosstabDataProvider c = new CrosstabDataProvider();c.RowHeadingSettings = RowHeadingSettings.Auto;

c.DataSource = l;

Chart.DataSourceSettings.Fields.Add(new FieldMap("SerieName", FieldUsage.ColumnHeading));

Chart.DataSourceSettings.Fields.Add(

new FieldMap("XValue", FieldUsage.RowHeading));Chart.DataSourceSettings.Fields.Add(new FieldMap("YValue", FieldUsage.Value));

 

Chart.DataSource = c;

 And my issue is when I set the RowHeadingSettings property of my crossTabDataProvider to "Auto", labels on the X-Axis are well displayed but not in ascending order and when I set the same property to "XValues" I don't have all X-Axis labels and sometimes the x-Axis label displayed is not the corresponding X value of the chart (Maybe I'm not very clear...).(see file attached)

Can you help me?

Thank you

 

 

[Xml column name]

In fact, I use a string "Xml" not a file but it's the same.

Code:

xml = GetXmlChain();

XmlDataProvider xmlDataProvider = new XmlDataProvider();

xmlDataProvider.LoadXml(xml);

 

int i = xmlDataProvider.Columns.Count;// i = 0??

chart.DataSourceSettings.DataSource = xmlDataProvider;

[Hidden point]

Hi,

I have a problem with hidden points with a curve chart. I enabled the property "InterpolateHidden" and I have a blank with curve chart (see file attached) but with lines chart I don't have it. Maybe I made a mistake or forgot something, can you help me?

Thank you

[Xml column name]

hi,

I bind my chart with an xml file and I need to get columns name in order to specify the property of each column.

I use a XmlDataProvider and after loading my xml file I can't have any access to my columns name ( columns count = 0).

Can you help me.

Thank you

 

[business object]

I made a mistake in my post :

chart.DataSource = c;// the CrossTabDataProvider

[business object]

hello,

I want to bind a chart with my business object.

I have a class:

class

MyData

{

string _serieName;

object _xValue; double _yValue;public MyData(string serieName, object xvalue, double value)

{

_serieName = serieName; 

_xValue = xvalue;

 

_yValue = value;

}

public object XValue {get { return _xValue; } }

public string SerieName { get { return _serieName; } }public double YValue {get { return _yValue; } }

}

 xvalue is an object because I can have double values, datetime values or string values. I can have a chart but I want the axisX to be sorted in ascending order because when I try like that:

MyData[] testArray = new MyData[3];

testArray[0] =

new MyData"serieA", 2, 12);testArray[1] = new MyData("SerieB", 1, 16);

testArray[2] =

new MyData("SerieC", 3, 15);ListProvider l = new ListProvider(testArray);CrosstabDataProvider c = new CrosstabDataProvider();

c.DataSource = l;

chart.DataSourceSettings.Fields.Add(

new FieldMap("SerieName", FieldUsage.ColumnHeading));chart.DataSourceSettings.Fields.Add(new FieldMap("XValue", FieldUsage.RowHeading) );

chart.DataSourceSettings.Fields.Add(

new FieldMap("YValue", FieldUsage.Value));

chart.DataSource = testArray;

I have a good chart but labels on axisX are in this order : 2 - 1 - 3 (the order in the tab).

I think it's a normal behaviour but is there a way to display a chart with axisX sorted?

Thank you.

[Datagrid problem]

hello,

I have something strange: I have 5 series of 5 values ("Currency" around 8 or 9 figures), I use a BarChart(3D, cylinder) and when I display the datagrid with the option "Stacked" the datagrid displays a scrollbar and all values are well-readable. But if I choose "Stacked 100%" all columns in the datagrid are compressed, so the reading is difficult (numbers are cut). Can you help me?

thank you.
