This is the code being used:
ClearAndResetAppliedToolSettings();
UpdateCursorFromControls();
var dateTimePagingView = _chartPrimaryXAxis.PagingView as NDateTimeAxisPagingView;
if (dateTimePagingView != null)
{
_chartPrimaryXAxis.ScrollBar.Visible = false;
dateTimePagingView.ResetMode = PagingViewResetMode.View;
dateTimePagingView.Reset();
dateTimePagingView.ResetMode = PagingViewResetMode.LastZoom;
}
_chartControl.Controller.Selection.Clear();
_chartControl.Controller.Selection.Add(_chartControl.Charts[0]);
_chartControl.Controller.Tools.Add(_chartDataCursorTool);
_chartControl.Refresh();
UpdateResultsViewReloadState();

Hi James,
We just tested the data cursor example shipped with the control and it was working properly with this version. Can you post the complete code that automates the control for review?

I was able to get it to work by rearranging the order of some code.
Thanks
Jim

Sorry I didn't get back earlier. I'm new to this tool and taking over some existing code. In this code we zoom in using NDataZoomTool. We then try to turn on the NDataCursorTool. This turns off the data zoom. Is it possible to do this separately?
Some sample code of how to use these two tools together would be very helpful.
Thanks
Jim

My question is can NDataZoomTool and NDataCursorTool be used at the same time in NChartControl? If so . . . what does this code look like?
In our application it use of one appears to override the other control.

Hi James,
The following code shows how you can mix the data cursor tool with other tools:
NCartesianChart chart = (NCartesianChart)nChartControl1.Charts[0];
chart.RangeSelections.Add(new NRangeSelection());
NAxisCursor xAxisCursor = new NAxisCursor();
xAxisCursor.SynchronizeOnMouseAction = MouseAction.Move;
xAxisCursor.BeginEndAxis = (int)StandardAxis.PrimaryY;
chart.Axis(StandardAxis.PrimaryX).Cursors.Add(xAxisCursor);
NAxisCursor yAxisCursor = new NAxisCursor();
yAxisCursor.SynchronizeOnMouseAction = MouseAction.Move;
yAxisCursor.BeginEndAxis = (int)StandardAxis.PrimaryX;
chart.Axis(StandardAxis.PrimaryY).Cursors.Add(yAxisCursor);
chart.Axis(StandardAxis.PrimaryX).ScrollBar.Visible = true;
chart.Axis(StandardAxis.PrimaryY).ScrollBar.Visible = true;
NPointSeries pointSeries = new NPointSeries();
pointSeries.Values.Add(10);
pointSeries.Values.Add(20);
pointSeries.Values.Add(30);
chart.Series.Add(pointSeries);
nChartControl1.Controller.Tools.Add(new NPanelSelectorTool());
nChartControl1.Controller.Tools.Add(new NAxisScrollTool());
nChartControl1.Controller.Tools.Add(new NDataZoomTool());
nChartControl1.Controller.Tools.Add(new NDataCursorTool());
Note that when a drag tool begins an operation (NDataZoomTool or NAxisScrollTool) it will capture all events until the operation is complete as it becomes an active tool. Do you want to have data cursors synchronized during a drag operation - for example data zoom?

I am able to get the NDataCursorTool on the zoom screen. The one issue I'm having is that it now interferes with access to the scrolling tools at the bottom of the zoom screen.
Here's what my code looks like:
void resultVisualizationHeader1_MouseZoom(object sender, EventArgs e)
{
zoomToolOn = !zoomToolOn;
if (_resultsViewInfo.ProcessedTimeStep == ViewReportingFrequency.Monthly || _resultsViewInfo.ProcessedTimeStep == ViewReportingFrequency.Run_Period)
{
MessageBox.Show(MessageAndPrompts.INFORM_DATAZOOM_TOOL_FREQUENCY_COMPATIBITLIY);
return;
}
ClearAndResetAppliedToolSettings();
_chartControl.Controller.Tools.RemoveAllChildren();
_chartControl.Controller.Selection.Clear();
_chartControl.Controller.Selection.Add(_chartControl.Charts[0]);
if (cursorToolOn)
{
//_chart.RangeSelections.Add(new NRangeSelection());
NAxisCursor xAxisCursor = new NAxisCursor();
xAxisCursor.SynchronizeOnMouseAction = MouseAction.Move;
xAxisCursor.BeginEndAxis = (int)StandardAxis.PrimaryY;
_chart.Axis(StandardAxis.PrimaryX).Cursors.Add(xAxisCursor);
NAxisCursor yAxisCursor = new NAxisCursor();
yAxisCursor.SynchronizeOnMouseAction = MouseAction.Move;
yAxisCursor.BeginEndAxis = (int)StandardAxis.PrimaryX;
_chart.Axis(StandardAxis.PrimaryY).Cursors.Add(yAxisCursor);
}
_chartPrimaryXAxis.ScrollBar.Visible = true;
_chartPrimaryYAxis.ScrollBar.Visible = true;
var dateTimePagingView = _chartPrimaryXAxis.PagingView as NDateTimeAxisPagingView;
if (dateTimePagingView != null)
{
_chartPrimaryXAxis.ScrollBar.Visible = true;
dateTimePagingView.ResetMode = PagingViewResetMode.View;
dateTimePagingView.Reset();
dateTimePagingView.ResetMode = PagingViewResetMode.LastZoom;
}
_chartPrimaryYAxis.PagingView = new NNumericAxisPagingView();
UpdateDataZoomTool();
UpdateDateTimeScale();
_dateTimeScale.EnableUnitSensitiveFormatting = true;
// configure interactivity
_chartControl.Controller.Tools.Add(new NSelectorTool());
_chartControl.Controller.Tools.Add(_chartDataZoomTool);
_chartControl.Controller.Tools.Add(_chartDataCursorTool);
_chartControl.Controller.Tools.Add(new NAxisScrollTool());
_chartControl.Refresh();
UpdateResultsViewReloadState();
}
private void ClearAndResetAppliedToolSettings()
{
if (_chartDataCursorTool != null)
{
if (_chartControl.Controller.Tools.Contains(_chartDataCursorTool))
{
NChart chart = _chartControl.Charts[0];
NAxis primaryXAxis = chart.Axis(StandardAxis.PrimaryX);
NAxis primaryYAxis = chart.Axis(StandardAxis.PrimaryY);
NAxis depthAxis = chart.Axis(StandardAxis.Depth);
primaryXAxis.Cursors.Clear();
primaryYAxis.Cursors.Clear();
toolTip1.SetToolTip(_chartControl, "");
}
}
//Reset all Chart interaction controls
_chartControl.Controller.Tools.RemoveAllChildren();
if (_resultsViewInfo.ChartType == ChartOrTableType.Bar3d)
{
_chartControl.Controller.Tools.Add(new NSelectorTool());
_chartControl.Controller.Tools.Add(new NTrackballTool());
}
_chartPrimaryXAxis.ScrollBar.Visible = false;
_chartPrimaryYAxis.ScrollBar.Visible = false;
this.Cursor = Cursors.Default;
ChartCategory chartCategory = GetChartCategory(_resultsViewInfo.ChartType);
if (chartCategory == ChartCategory.Column || chartCategory == ChartCategory.Range)
{
_chartPrimaryXAxis.PagingView = null;
_chartPrimaryXAxis.Visible = _resultsViewInfo.ResultsViewVariables.Count != 0;
}
else
{
if (_resultsViewInfo.ResultsViewVariables.Count == 0)
{
_chartPrimaryXAxis.PagingView = new NDateTimeAxisPagingView();
}
}
_chartPrimaryYAxis.PagingView = new NNumericAxisPagingView();
;
}
private void UpdateResultsViewReloadState()
{
_chartControl.document.Calculate();
_chartControl.document.RecalcLayout(_chartControl.View.Context);
//dateTimeScale
NRange1DD xAxisRange = _chart.Axis(StandardAxis.PrimaryX).Scale.RulerRange;
DateTime startdate = DateTime.FromOADate(xAxisRange.Begin);
DateTime enddate = DateTime.FromOADate(xAxisRange.End);
_resultsViewInfo.StartDate = startdate;
_resultsViewInfo.EndDate = enddate;
Debug.WriteLine("StartDate:" + startdate.ToString() + " - EndDate:" + enddate.ToString());
}
This is the code that initially turns on the Data Cursor:
void resultVisualizationHeader1_MouseTrackBallSelect(object sender, EventArgs e)
{
if (!zoomToolOn)
{
if (!cursorToolOn)
{
ClearAndResetAppliedToolSettings();
UpdateCursorFromControls();
var dateTimePagingView = _chartPrimaryXAxis.PagingView as NDateTimeAxisPagingView;
if (dateTimePagingView != null)
{
_chartPrimaryXAxis.ScrollBar.Visible = false;
dateTimePagingView.ResetMode = PagingViewResetMode.View;
dateTimePagingView.Reset();
dateTimePagingView.ResetMode = PagingViewResetMode.LastZoom;
}
_chartControl.Controller.Selection.Clear();
_chartControl.Controller.Selection.Add(_chartControl.Charts[0]);
_chartControl.Controller.Tools.Add(_chartDataCursorTool);
_chartControl.Refresh();
UpdateResultsViewReloadState();
cursorToolOn = true;
}
else
{
ClearAndResetAppliedToolSettings();
UpdateCursorFromControls();
_chartControl.Controller.Selection.Clear();
_chartControl.Controller.Selection.Add(_chartControl.Charts[0]);
//_chartControl.Controller.Tools.Remove(_chartDataCursorTool);
_chart.Axis(StandardAxis.PrimaryX).Cursors.Clear();
_chart.Axis(StandardAxis.PrimaryY).Cursors.Clear();
_chartControl.Refresh();
cursorToolOn = false;
}
}
else
{
MessageBox.Show(MessageAndPrompts.INFORM_DATATRACK_TOOL_BEFORE_ZOOM);
}
}
private void UpdateCursorFromControls()
{
_chartHorizontalAxisCursor.ValueSnapper = null;
_chartVerticalAxisCursor.ValueSnapper = null;
NAxis depthAxis = _chart.Axis(StandardAxis.Depth);
_chartPrimaryXAxis.Cursors.Clear();
_chartPrimaryYAxis.Cursors.Clear();
depthAxis.Cursors.Clear();
_chartPrimaryXAxis.Cursors.Add(_chartHorizontalAxisCursor);
_chartPrimaryYAxis.Cursors.Add(_chartVerticalAxisCursor);
_chartHorizontalAxisCursor.SynchronizeOnMouseAction = MouseAction.None;
_chartVerticalAxisCursor.SynchronizeOnMouseAction = MouseAction.None;
_chartHorizontalAxisCursor.SynchronizeOnMouseAction |= MouseAction.Down;
_chartVerticalAxisCursor.SynchronizeOnMouseAction |= MouseAction.Down;
_chartHorizontalAxisCursor.SynchronizeOnMouseAction |= MouseAction.Up;
_chartVerticalAxisCursor.SynchronizeOnMouseAction |= MouseAction.Up;
_chartHorizontalAxisCursor.SynchronizeOnMouseAction |= MouseAction.Move;
_chartVerticalAxisCursor.SynchronizeOnMouseAction |= MouseAction.Move;
}
Note: You will notice that I require that the user turns on the cursor before turning on zoom.
Thanks for your help.
Jim

I was able to get the NDataCursorTool to appear in my zoom screen
My issue is that the cursor now interferes with the tracking tool at the bottom of the zoom screen.

Hi James,
Let's schedule an online 15 minute meeting to discuss - we think it will be more productive than exchanging posts. If you're keen to do it this way please send an e-mail to support@nevron.com to schedule a meeting...
