Hi Team,
I am using zoom for both WPF(NChartControl) and Web application(NThinChartControl). Initially I have scale breaks in my chart with zooming enabled, as soon as user zoom into the chart I want to clear scale breaks, I found a way to do that for NThinChartControl in Nevron.Chart.ThinWeb.NDataZoomTool, I set DataZoomCallback and then in OnDataZoom method I have logic to clear scale breaks.

I wanted to know is it possible to have this functionality in NChartControl? Is there any other workaround to achieve what I want to achieve?

Thanks and regards
Manal

Hi Manal,
This code looks ok however it is unclear whether you use a single chart panel or multiple chart panels. In case you use a single chart panel with many docked Y axes you also need to specify the vertical axis for the range selection. For example:
rangeSelection.VerticalAxisId = someAxis.AxisId;
You can also send us a snapshot of the chart state:
nChartControl1.Serializer.SaveControlStateToFile("c:\\temp\\chartstate.xml", Nevron.Serialization.PersistencyFormat.CustomXML, null);
(you need to send us the generaed chartstate.xml file) so that we can investigate further.

Hope this helps - let us know if you meet any problems or have any questions.

Hi,

I have used a similar way that is present in exmaples->RealTime->RealTimeLine
like this:
NAxis axis1 = chart.Axis(StandardAxis.PrimaryY);
ConfigureAxis(axis1, 0, 30, "Signal 1");

NAxis axis2 = chart.Axis(StandardAxis.SecondaryY);
ConfigureAxis(axis2, 35, 65, "Signal 2");

NAxis axis3 = ((NCartesianAxisCollection)chart.Axes).AddCustomAxis(AxisOrientation.Vertical, AxisDockZone.FrontRight);
ConfigureAxis(axis3, 70, 100, "Signal 3");

I want the range selection box to appear across whole y axis.

I tried what you suggested like:
    NRangeSelection rangeSelection = new NRangeSelection();
    rangeSelection.VerticalValueSnapper = new NAxisRulerMinMaxSnapper();
    ((NCartesianChart)chart).RangeSelections.Add(rangeSelection);
    rangeSelection.VerticalAxisId = 1;

but that did not make any difference.

Hi Manal,
We were not able to replicate the problem - we tested with the following code:
using Nevron.Chart;
using Nevron.Chart.Windows;
using System;
using System.Windows.Forms;

namespace WindowsFormsApp2
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}


private void Form1_Load(object sender, EventArgs e)
{
NCartesianChart chart = (NCartesianChart)nChartControl1.Charts[0];
chart.Axis(StandardAxis.PrimaryX).ScrollBar.Visible = true;

NAxis axis1 = chart.Axis(StandardAxis.PrimaryY);
ConfigureAxis(axis1, 0, 30, "Signal 1");

NAxis axis2 = chart.Axis(StandardAxis.SecondaryY);
axis2.Visible = true;
ConfigureAxis(axis2, 35, 65, "Signal 2");

NAxis axis3 = ((NCartesianAxisCollection)chart.Axes).AddCustomAxis(AxisOrientation.Vertical, AxisDockZone.FrontRight);
ConfigureAxis(axis3, 70, 100, "Signal 3");

NRangeSelection rangeSelection = new NRangeSelection();
rangeSelection.VerticalValueSnapper = new NAxisRulerMinMaxSnapper();
rangeSelection.VerticalAxisId = axis2.AxisId;
chart.RangeSelections.Add(rangeSelection);

NLineSeries line1 = new NLineSeries();
FillData(line1);
chart.Series.Add(line1);

NLineSeries line2 = new NLineSeries();
FillData(line2);
chart.Series.Add(line2);
line2.DisplayOnAxis(StandardAxis.PrimaryY, false);
line2.DisplayOnAxis(axis2.AxisId, true);

NLineSeries line3 = new NLineSeries();
FillData(line3);
chart.Series.Add(line3);
line3.DisplayOnAxis(StandardAxis.PrimaryY, false);
line3.DisplayOnAxis(axis3.AxisId, true);

nChartControl1.Controller.Tools.Add(new NPanelSelectorTool());
nChartControl1.Controller.Tools.Add(new NAxisScrollTool());
nChartControl1.Controller.Tools.Add(new NDataZoomTool());

}

private void FillData(NLineSeries line)
{
Random rand = new Random();
line.DataLabelStyle.Visible = false;
for (int i = 0; i < 100; i++)
{
line.Values.Add(rand.Next(100));
}
}

private void ConfigureAxis(NAxis axis, float beginPercent, float endPercent, string text)
{
axis.Anchor = new NDockAxisAnchor(AxisDockZone.FrontLeft, false, beginPercent, endPercent);

NLinearScaleConfigurator scale = new NLinearScaleConfigurator();
scale.Title.Text = text;
axis.ScaleConfigurator = scale;
}
}
}

and the control was working properly. Can you sends us a small application that replicates this problem?

Hi Team,

where should I send the sample application?

Hi Manal,

Please send the application to support@nevron.com. Thank you.
