Re: [Nplot-devel] StartTradingTime and EndTradingTime problem

[Pete S. <edg...@ya...>]

Hello,

I was trying to do the same thing and found your post. I found that you need to rescale the XAxis once you plug in the tradingtime ranges. It's probably not the right way, but I just used the previous XAxis WorldMin and WorldMax values for the new Xaxis. It then works exactly as we want.

-pete

Hi,

I have a intraday stock data. The quotations are between 09:30 and 16:30 so i have gap on the chart (from 16:30 to 9:30 next day). I saw StartTradinTime and EndTradingTime properties (btw great idea) but i must do something wrong because when i set that properties the chart is empty :(

TradingDateTimeAxis TimeAxis = new TradingDateTimeAxis(plotsurface.XAxis1);
TimeAxis.StartTradingTime = new TimeSpan(09, 30, 00);
TimeAxis.EndTradingTime = new TimeSpan(16, 30, 00);
plotsurface.XAxis1 = TimeAxis;

In that case chart is empty, but after i comment TimeAxis.StartTradingTime and TimeAxis.EndTradingTime chart is plot but with gap...

Thank you for help and best regards
Jack

Summary: Clipping Error in Step Plots

Initial Comment:
The same clipping problem someone stated before applies also to StepPlots. If one point is on the left but outside the screen area and the other on the right but out side the screen area, the chart is not drawn.

I would suggest to change the clipping algorithm in StepPlots.cs to something like:

// do horizontal clipping here, to speed up
if ((p1.X < leftCutoff && p2.X < leftCutoff && p3.X < leftCutoff) ||
    (p1.X > rightCutoff && p2.X > rightCutoff && p3.X > rightCutoff ))
{
	continue;
}

This works for me.

Message:
Mono bug #475578 does not compile 'const double' correctly. 

This bug is fixed in Mono svn and in the upcoming release 2.4, but the
attached patches for Axis.cs and TradingDateTimeAxis.cs fix the problem for
current Mono releases.  As the const is used only in the local method,
removing it does not cause any issues or inefficiency.

Summary: PlotSurface2D displays data incorrectly when YAxis1.Reversed

Initial Comment:
I am using NPlot to display contour charts using PlotSurface2D.  When I reverse the Y axis order the chart does not display correctly.

My data goes from 0,0 to 10,10 (11 rows and 11 columns).  I want data point 0,0 to appear in the upper left hand corner of the plot.  The default has Y values increasing so 0,0 is in the lower left.

When I set YAxis1.Reversed I get the desired effect of the numbers on the Y axis (0 is at the top and 10 is at the bottom).  But the data is plotted incorrectly.  Data from row 0 is plotted on row 1, etc.  

Here is a code fragment for how I am plotting the data:

	int row = 10;
	int col = 10;
	double[,] map = new double[row, col];
		for (int i = 0; i < row; i++)
		{
			for (int j = 0; j < col; j++)
			{
				map[i, j] = i;
			}
		}
	this.myPlotSurface.Clear();
	myPlotSurface.Title = "Grid Survey";
	NPlot.ImagePlot ip = new NPlot.ImagePlot(map, 0, 1, 0, 1);
	ip.Gradient = new NPlot.LinearGradient(Color.Blue, Color.Red);
	ip.Center = false;
	myPlotSurface.Add(ip);

	// Reverse Y axis so grid matches physical space
	myPlotSurface.YAxis1.Reversed = true;

	NPlot.Grid grid = new NPlot.Grid();
	grid.HorizontalGridType = NPlot.Grid.GridType.Fine;
	grid.VerticalGridType = NPlot.Grid.GridType.Fine;
	myPlotSurface.Add(grid);
	myPlotSurface.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.Default;
	myPlotSurface.AddInteraction(new NPlot.Windows.PlotSurface2D.Interactions.MouseWheelZoom());
	myPlotSurface.Refresh();

Summary: Problems ploting single point

Initial Comment:
Hi,

My program plots various LinePlots and PointPlots using the AbscissaData and OrdinateData.  The data can change based on user interaction.  A bug occurs when the data is for only one point.  

First there is an exception in 
DateTimeAxis.cs 
void DrawTicks(...)
{
...
PointF lastPos = WorldToPhysical((double)largeTicks[0], physicalMin, physicalMax, true);//ed

The exception is due to accessing largeTicks[0].  The previous call to WorldTickPositions() fails to add any data to the largeTicks array.

A quick fix was to add the following code:
if (largeTicks.Count <= 0) { return; }

But the result is not very satisfactory as I'd still like to see the point plotted.  My temporary hack was to adjust the XAxis1.WorldMax and XAxis1.WorldMin by 100 so as to show a centered point but this is far from ideal.

Thanks,
Randal

If you open this file in wordpad, right at the very end of the file is where the problem seems to be.

Summary: Utilities additions for Axis.cs

Initial Comment:
Additional methods are provided for modifying and defining the WorldRange of an Axis.
These are all based on expressing the new WorldMin and WorldMax as proportions of the current range, as done in the existing 'IncreaseRange' method.  

This approach greatly simplifies any re-ranging done as a result of Mouse Interactions, so that more common code can be used here.
NB - CSDiff file attached is wrt svn revision 31, and also contains TicksAngle and Mono Bugfix patches as well

Summary: Interactions fail in Managed C++ code calls.

Initial Comment:
Hello,

I'm writing a .NET 2003 Managed C++ application.  When I try to create an interaction, the initialization fails because in NPlot 0.9.9.2, Interactions is an abstract class containing Interaction.  In .NET 2003 Managed C++, this abstract class is considered like a pure virtual class and so it doesn't recognize that there's a definition within it.

My solution was to remove the Interactions wrapper which is not the cleanest design, but at least my C++ code can now instantiate the Interaction ok and my charts look very pretty.

Thank you for all the hard work you've put into this valuable resource.

Sincerely,

James Lefeu

Mono bug #475578 does not compile 'const double' correctly. 

This bug is fixed in Mono svn and in the upcoming release 2.4, but the
attached patches for Axis.cs and TradingDateTimeAxis.cs fix the problem for
current Mono releases.  As the const is used only in the local method,
removing it does not cause any issues or inefficiency.

Summary: DateTimeAxis throws unhandled exception due to WorldMax Bug.

Initial Comment:
In the file attached, I am trying to create two linePlots and add them to a single Plotting Surface, based off NPlot's example code. 
If the second LinePlot is not added to the plotting surface, everything works.

However, if the second line is added (using the same date range) the program crashed with a "ArguementOutOfRangeException: The added or subtracted value results in an un-representable DateTime.
Parameter name: months" on DateTimeAxis.cs line 587.

The real problem seems to be traced back to lines 326 and 327 of the file:
		DateTime worldMinDate = new DateTime( (long)this.WorldMin );
		DateTime worldMaxDate = new DateTime( (long)this.WorldMax );

The WorldMin seems to be 0, the "dawn of time", so to speak, and the WorldMax is some ungodly large number. (And I'm only trying to chart 50 days worth of data, and its larger than 50 days in ticks). That's as far as I've narrowed it so far. A breakpoint where the property is set might help narrow it done, and I'm going to try that next.

Thanks for all the great work you've done so far. Good Hunting.

Message:
I've seen the same exception before.  I was using a TradingDateTimeAxis for
a CandlePlot but was setting the axis before adding the plot.  This caused
the WorldMin to remain zero causing the worldMinDate to be invalid.  I
worked around this problem by setting the CandlePlot data first, and then
creating a new TradingDateTimeAxis initialized from the CandlePlot's
SuggestXAxis() call before passing it into the graph.  Then when I stepped
through the NPlot source, WorldMin was no longer zero and the worldMinDate
was correct.

[Nplot-devel] NPlot.LogAxis

[Xavier P. <xav...@e-...>]

Hi everybody,    

 

I'm using NPlot and I have a little problem setting the Y Axis as

NPlot.LogAxis

 

I've got YDAT as the linear array of double values I want to plot

 

I am only able to use the expression NPlot.StepPlot.DataSource = YDAT in

order to plot the linear version of the plot

 

But NPlot.StepPlot.DataSource is set to LinearAxis by default, and I don't

know how to change that

 

Any ideas? 

 

(by the way, as you may have noticed, I am using vbnet)

 

Thank you very much for your help

 

Xavier

Re: [Nplot-devel] How do I set the width for axis labels?

[Benjamin K. <ben...@go...>]

Hi Dave

Sorry, but your solution didn't work for me. However, I've found a  
workaround.

1. Set the TickText font to a monospaced font (e. g. Courier New)
2. Supress commas by specifying {0:F0} as number format
    (this is OK for the moment but needs to be changed if I need  
floating point labels)
3. Loop through all the PlotSurface2D and find the largest WorldMin/ 
WorldMax
    (with double.ToString("F0").Length)
4. Set margin and width for each P2D based on this values

            plotSurface1.YAxis1.AutoScaleTicks = true;
            plotSurface1.YAxis1.Label = " ";
            plotSurface1.YAxis1.LabelOffset = 50;
            if ((double)chartDataTable.Rows[0][4] > 25) // xxx vs jpy
                plotSurface1.YAxis1.NumberFormat = "{0:F2}";
            else
                plotSurface1.YAxis1.NumberFormat = "{0:F4}";

            plotSurface1.YAxis2 = (Axis)plotSurface1.YAxis1.Clone();
            plotSurface1.YAxis2.TickTextNextToAxis = false;
            plotSurface1.YAxis2.Label = " ";
            plotSurface1.YAxis2.LabelOffset = 50;

            plotSurface1.XAxis1 = new LinearAxis(plotSurface1.XAxis1);
            plotSurface1.XAxis1.IncreaseRange(1d /
chartDataTable.Rows.Count);
            plotSurface1.XAxis1.SmallTickSize = 1;
            plotSurface1.XAxis1.LabelOffset = 40;

            // Indicator Chart
            indicatorPlot.Clear();
            indicatorPlot.DateTimeToolTip = true;
            indicatorPlot.BackColor = Color.Cornsilk;
            indicatorPlot.PlotBackColor = Color.Ivory;

            indicatorPlot.Add(GetZeroLinePlot(), 1000);

            indicatorPlot.SmoothingMode =
System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
            indicatorPlot.Add(new Grid());
            indicatorPlot.Padding = 5;

[Nplot-devel] How do I set the width for axis labels?

[Benjamin K. <ben...@go...>]

Hi

I'm working on a WinForms app which displays many PlotSuface2Ds in a  
row:

100 |
    |
    |
50 |
    |
    |
  0 +--------------------------------

1000 |
     |
     |
500 |
     |
     |
   0 +-------------------------------

The lower plot is shifted to the right because the TickText is a bit  
wider. How can I prevent this from happening? I've tried some  
workarounds but they sucked:

- Rotated TickTexts by 90° - looks ugly
- Moved TickTexts to the inside - looks even uglier

I think the optimal way of accomplishing this is by specifying the  
width for the TickTexts but I didn't find a way to modify the bounding  
box of the axis. Do I need to modify NPlot's source? If so, what is  
the best way?

Thanks in advance
-- Benjamin
