I am having trouble with some custom code, I want to get the range of my data and add a line midway

I tested out some code that works ok for a floatbar in the winforms charting object, and tried to use it in the reporting chart tool custom code.

double test = (double)floatBar.Values[0];

As soon as i put this code into my report it no longer runs as says there is an error, as soon as i remove  it it runs again.  Same for BeginValues, EndValues etc.

Am i doing something wrong?  I have two level grouping on my report but i'm not sure if that makes a difference.

Hi Clare,

Can you post the complete code you use in the report? The code excerpt above is not problematic by itself.

using System;

using System.Drawing;

using Nevron.GraphicsCore;

using Nevron.Chart;

using Nevron.ReportingServices;

namespace MyNamespace

/// <summary>

public static void RSMain(NRSChartCodeContext context)

{

if (context.Document.Charts.Count == 0)

return;

NChart chart = context.Document.Charts[0];

//Create shift markers

int shiftCount = context.GetInt32Parameter("shiftCount");

for (int i = 1; i < shiftCount; i++)

{

NFloatBarSeries floatBar = chart.Series[0] as NFloatBarSeries;

NAxis yAxis = chart.Axis((int)StandardAxis.PrimaryY);

//NAxisConstLine cl1 = chart.Axis(StandardAxis.PrimaryY).ConstLines.Add();

NAxisConstLine cl1 = yAxis.ConstLines.Add();

cl1.StrokeStyle.Color = Color.Purple;

cl1.StrokeStyle.Width = new NLength(1.5f);

cl1.FillStyle = new NColorFillStyle(new NArgbColor(125, Color.Purple));

cl1.Value = 40569.3;

double start = (double)floatBar.BeginValues[floatBar.BeginValues.Count - 1];

double end = (double)floatBar.EndValues[floatBar.BeginValues.Count - 1];

NAxisStripe s1 = chart.Axis(StandardAxis.PrimaryY).Stripes.Add(start, end);

s1.FillStyle = new NColorFillStyle(Color.FromArgb(125, Color.SteelBlue));

}

Ok, i added a test for empty values and now i dont get an error, however i only seem to have values in one of my begin and end values.

I changed the code so that a stripe was added for each valid start and end, and i ONLY get one stripe for the very first item??? (which incidentally was in beginvalues[3] and endvalues[3]

I'm really confused about why this might be so??

How do i access the rest of my values and why is it appearing that there is only one?  Could this be caused by grouping?

Hi Clare,

Can we schedule a web meeting? - it looks like the configuration / data does not match the standard example shipped with the control, which makes the results "unpredictable". To schedule a web meeting you can send an e-mail at "sales at nevron dot com".
