Below is the code used for creating chart with NZoomTool and NAxisScrollTool together. After zooming in or out, the scrollbars hovering functionality behave strangly (the scrollbar buttons highlight when mouse is slightly off the buttons). I am sure I am doing something silly or is there some other way to do this?



using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

using Nevron.GraphicsCore;
using Nevron.Chart;
using Nevron.Chart.WinForm;

namespace WindowsFormsApplication4
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();

nChartControl1.Legends.Clear();

NCartesianChart chart = (NCartesianChart)nChartControl1.Charts[0];

NAxis axisX = chart.Axis(StandardAxis.PrimaryX);
NNumericAxisPagingView xPagingView = new NNumericAxisPagingView(new NRange1DD(0, 100));
xPagingView.MinPageLength = 1.0;
axisX.PagingView = xPagingView;
axisX.ScrollBar.Visible = true;

NAxis axisY = chart.Axis(StandardAxis.PrimaryY);
NNumericAxisPagingView yPagingView = new NNumericAxisPagingView(new NRange1DD(0, 100));
yPagingView.MinPageLength = 1.0;
axisY.PagingView = yPagingView;
axisY.ScrollBar.Visible = true;

Random rand = new Random();
NPointSeries lineSeries = (NPointSeries)chart.Series.Add(SeriesType.Point);
for (int i = 0; i < 100; i++)
{
lineSeries.UseXValues = true;
lineSeries.XValues.Add(rand.Next(100));
lineSeries.Values.Add(rand.Next(100));
}

nChartControl1.Controller.Tools.Add(new NSelectorTool());
nChartControl1.Controller.Tools.Add(new NZoomTool());
nChartControl1.Controller.Tools.Add(new NAxisScrollTool());
}
}
}

... just a further remark:

the sequenze of the commands _NevronChart.Controller.Tools.Add when initializing the chart is very important:

//works perfect:
_NevronChart.Controller.Tools.Add(new NSelectorTool());

_DataZoomTool = new NDataZoomTool();
_NevronChart.Controller.Tools.Add(_DataZoomTool);

_AxisScrollTool = new NAxisScrollTool();
_NevronChart.Controller.Tools.Add(_AxisScrollTool);

//behaves strangly with "normal" data / application crash with larger data when chart is initialized again:
_DataZoomTool = new NDataZoomTool();
_NevronChart.Controller.Tools.Add(_DataZoomTool);

_AxisScrollTool = new NAxisScrollTool();
_NevronChart.Controller.Tools.Add(_AxisScrollTool);

_NevronChart.Controller.Tools.Add(new NSelectorTool());
