Scatter plot with multiple series

[User (Legacy)]

Ok, I´ve investigated the problem and here are my conclusions.

I have a function that creates the scatter plot. Here is a part of this 

function:

=========================================================

public void Update_TilePanel()

{

base.Data.Clear();

base.Points.Clear();

object[] allArrays = new object[5];

double[] Array_A = new double[lstPoint_A.Count];

double[] Array_B = new double[lstPoint_B.Count];

double[] Array_C = new double[lstPoint_C.Count];

double[] Array_Neutral = new double[lstPoint_Neutral.Count];

double[] XArray = new double[lstPoint_A.Count];

allArrays[0] = Array_A;

allArrays[1] = Array_B;

allArrays[2] = Array_C;

allArrays[3] = Array_Neutral;

allArrays[4] = XArray;

base.DataSourceSettings.Fields.Add(new FieldMap("Field1",

FieldUsage.Value));

base.DataSourceSettings.Fields.Add(new FieldMap("Field2",

FieldUsage.Value));

base.DataSourceSettings.Fields.Add(new FieldMap("Field3",

FieldUsage.Value));

base.DataSourceSettings.Fields.Add(new FieldMap("Field4",

FieldUsage.Value));

base.DataSourceSettings.Fields.Add(new FieldMap("Field5",

FieldUsage.XValue));

ListProvider lstProvider = new ListProvider(allArrays);

base.DataSourceSettings.DataSource = lstProvider;

}

==========================================================

The first time this function runs, only two series are displayed on my 

scatter plot. When I right-clik the plot, and select "Data Grid",

I see that only two series have correct "X" and "Y" values, and the other 

two series (Phase C and Neutral) have "Y-Values" but no

"X-Values" (see attached picture). Plus, I see 4 other series that have 

Y-values but no X-Values, and I have no idea where these series come from 

(see attached picture) The second time the function runs, Serie3 (PhaseC) 

now has correct "X-Values" but two other series are created, with no 

X-values... so I now have 8 series, but only 3 of them are correct. And the 

third time I run the function, all the series are generetaed correctly, but 

I have now 10 series, the 6 last have no X-Values. So I really don´t know 

why my 4 series are not displayed

correctly the first time the functions is run, and why other series are 

generated.

Thank you very much for your kind help.

Francisco,

Thank you very much, I added "base.DataSourceSettings.Fields.Clear();" and 

everything works fine.

Hello,

I have a scatter plot. When I write the following code, everything works 

fine. But this code isn't correct because if I have two points that have the 

same X-Value, these pointes will not be set correctly.

===================================================

object[] allArrays = new object[5];

double[] Array_A = new double[lstPoint_A.Count];

double[] Array_B = new double[lstPoint_B.Count];

double[] Array_C = new double[lstPoint_C.Count];

double[] Array_Neutral = new double[lstPoint_Neutral.Count];

String[] XArray = new String[lstPoint_A.Count];

allArrays[0] = Array_A;

allArrays[1] = Array_B;

allArrays[2] = Array_C;

allArrays[3] = Array_Neutral;

allArrays[4] = XArray;

ListProvider lstProvider = new ListProvider(allArrays);

base.DataSourceSettings.DataSource = lstProvider;

======================================================

So I wrote a code that use the X-Value. But when I write this other code 

(see below), I don't get a correct plot. I get a plot that contains only two 

sets of points, instead of 4...

======================================================

object[] allArrays = new object[5];

double[] Array_A = new double[lstPoint_A.Count];

double[] Array_B = new double[lstPoint_B.Count];

double[] Array_C = new double[lstPoint_C.Count];

double[] Array_Neutral = new double[lstPoint_Neutral.Count];

double[] XArray = new double[lstPoint_A.Count];

allArrays[0] = Array_A;

allArrays[1] = Array_B;

allArrays[2] = Array_C;

allArrays[3] = Array_Neutral;

allArrays[4] = XArray;

base.DataSourceSettings.Fields.Add(new FieldMap("Field1", 

FieldUsage.Value));

base.DataSourceSettings.Fields.Add(new FieldMap("Field2", 

FieldUsage.Value));

base.DataSourceSettings.Fields.Add(new FieldMap("Field3", 

FieldUsage.Value));

base.DataSourceSettings.Fields.Add(new FieldMap("Field4", 

FieldUsage.Value));

base.DataSourceSettings.Fields.Add(new FieldMap("Field5", 

FieldUsage.XValue));

ListProvider lstProvider = new ListProvider(allArrays);

base.DataSourceSettings.DataSource = lstProvider;

========================================================

What am I doing wrong?

Thx!

I think all your problems come from not clearing DataSourceSettings.Fields 

every time, so you are adding new columns every time.

Add the following to your code:

base.DataSourceSettings.Fields.Clear();

Also try this before setting the DataSource:

chart.Data.X.Shared = true;
