Re: [Nplot-devel] Copy to clipboard

[Thomas E. <th...@th...>]

Just tried once again, and the problem appears in another shape now: 
When I use the CopyToClipboard()-function, I can paste the clipboard 
content to Irfanview, but not to Openoffice Writer. The latter is not 
showing any clipboard content. Is it possible, that the dataformat is 
not set properly? If I try the CopyDataToClipboard(), it is working fine 
instead.

Thanks,
    Thomas

[Dave C. <dav...@gm...>]

Worked for me:



        private void lblSide_DoubleClick(object sender, EventArgs e) {
            plotSurface1.CopyToClipboard();
            CopyClipboardToFile("test.jpg");

        }

        private bool CopyClipboardToFile(string bmpFilename) {
            IDataObject d = Clipboard.GetDataObject();
            Bitmap bmpImage;
            if ((d != null) && (d.GetDataPresent(DataFormats.Bitmap))) {
                bmpImage =
(Bitmap)(Clipboard.GetDataObject().GetData(DataFormats.Bitmap));
                bmpImage.Save(bmpFilename, ImageFormat.Jpeg);
                return true;
            }
            return false;
        }

Re: [Nplot-devel] Copy to clipboard

[Hywel T. <hy...@co...>]

Hello,

I've just tried the NPlotDemo from the svn version, and by 
Right-clicking on the plot area you can select Copy to clipboard. If you 
open (say) Microsoft Word and Paste into this, the plot itself (but not 
the axes, as far as I can see) are pasted in.  This seems a bit 
half-finished to me, but is this what you mean? Or have you not 
succeeded in doing even this?

Regards,

H.W.Thomas

Hello to the NPlot-team,

following a recommendation I am using NPlot now for some time, and I am 
really happy with it. However, every time I enter the wiki-homepage, I 
need to roll-back the tutorial-pages to a status, which includes 
something else than links created by some robots.

I think, you should change this page to be somehow protected. Perhaps by 
using captchas or similar?

Greetings,
    Thomas

[Nplot-devel] Is the NPlot Project still ACTIVE?

[Simon H. <hu...@gm...>]

Hi all,

I found that the last update of the NPlot project is on November 14, 2006.
Since then there is only an survey about the NPlot chart library. That is to
say,   There is no update for full of 2 years since the last update.

I need plotting many scientific figure in my development.  I use C#
collaborating with gnuplot(http://www.gnuplot.info/)
<http://www.gnuplot.info/>before
I found the NPlot chart library. Although inconveniently, but it works!

Now I want to use NPlot instead of gnuplot, because integration is
attractive. Is the author of the NPlot still caring for the project?

Thanks.

Sincerely,

Simon Huskier

[Nplot-devel] Problem with Candleplot

[dynamix . <dy...@li...>]

Hi - im writing an app in vb.net 2008 express and nplot is great - does everything i need it to do but i have 1 issue.
I am displaying stock info on a chart and i have the bottom axis set to a trading axis, the price is on the right side axis.
I have a lil drop down box where i can select the chart type, line, point, bar and candle plot.
All work fine except the candle plot, if i view it on 5 years or on 10 years it works fine, any shorter than that and the axises change correctly but the candle plot fails to display.
I tried changing the candle width and a few other various settings but i just cant get it sorted out. I dont see how this is failing as the same code that draws the 5 year and 10 year plot is failing at trying to draw any plots shorter.

Any ideas on what could be causing this, or small things about the candle plot that i obviously overlooked ?

Thank you kindly in advance.

the NPlot.csproj file seems to be corrupt in the zip file download.  I have downloaded it twice and it will not load when opening the solution

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

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();

Re: [Nplot-devel] Zooming with NPlot

[Hywel T. <hy...@co...>]

The PlotSurface needs to have the focus in order to receive MouseWheel 
events.  If you change the OnMouseMove (in Windows.PlotSurface2D) to:-

protected override void OnMouseMove(MouseEventArgs e)
{
	this.Focus();	// Set Focus to receive MouseWheel events
	DoMouseMove( e, this );
	base.OnMouseMove( e );
}

then you will see the ABC demo working as intended, with the plot 
getting Focus when the mouse is moved over it.

Re: [Nplot-devel] candleplot question

[Dave C. <dav...@gm...>]

I've never used this technique to build candles. I've always used the
example code that uses a DataTable.
        chartDataTable = new DataTable();

        protected void DataTablePrepare(DataTable chartDataTable) {
            chartDataTable.Columns.Add(new DataColumn("StringDate",
typeof(string)));
            chartDataTable.Columns.Add(new DataColumn("Open",
typeof(double)));
            chartDataTable.Columns.Add(new DataColumn("High",
typeof(double)));
            chartDataTable.Columns.Add(new DataColumn("Low",
typeof(double)));
            chartDataTable.Columns.Add(new DataColumn("Close",
typeof(double)));
            chartDataTable.Columns.Add(new DataColumn("Volume",
typeof(double)));
            chartDataTable.Columns.Add(new DataColumn("CloseAdj",
typeof(double)));
            chartDataTable.Columns.Add(new DataColumn("Date",
typeof(DateTime)));
            chartDataTable.Columns.Add(new DataColumn("Sequence",
typeof(int)));
        }


Fill your datatable with data here:

if (addQuote)
   chartDataTable.Rows.Add(new object[] { datestring, quote.Open,
quote.High, quote.Low, quote.Close, quote.Volume, quote.PrevClose,
DateTime.Now, quoteSequence });


And then in your plot redraw method:

            // create CandlePlot.
            CandlePlot cp = new CandlePlot();
            cp.DataSource = chartDataTable;
            cp.AbscissaData = "Sequence";
            cp.OpenData = "Open";
            cp.HighData = "High";
            cp.LowData = "Low";
            cp.CloseData = "Close";
            cp.BearishColor = Color.Red;
            cp.BullishColor = Color.Green;
            cp.Style = CandlePlot.Styles.Filled;

            plotSurface.Add(cp, 1000);

[Nplot-devel] candleplot question

[dynamix . <dy...@li...>]

Hi, 

I have a problem with the candle plot.
I created arrays of highs, lows, opens, closes and dates and this info displays fine if i create 4 line plots each with the same dateset based on each batch of info in those arrays. When i try to put that info into a candle plot display it either doesnt display anything or sometimes spits out a divide by 0 error.
Im moving info from an arraylist to an array first - with the line plot either way it works, just not with the candle plot.
I made a separate test app and that works fine, i dont see what im doing differently here? 

Here is my code.

ElseIf strMainPlotType = "CandleStick" Then

            Dim pqrs As Integer

            pqrs = closedata1.Count - 1
            Dim closedataarray As Double() = New Double(pqrs) {}
            Dim opendataarray As Double() = New Double(pqrs) {}
            Dim highdataarray As Double() = New Double(pqrs) {}
            Dim lowdataarray As Double() = New Double(pqrs) {}
            Dim datedataarray As Date() = New Date(pqrs) {}

            For z = 0 To closedata1.Count - 1
                closedataarray(z) = closedata1(z)
                opendataarray(z) = opendata1(z)
                highdataarray(z) = highdata1(z)
                lowdataarray(z) = lowdata1(z)

Re: [Nplot-devel] Zooming with NPlot

[Dave C. <dav...@gm...>]

I, personally, could never get the mousewheel interaction to perform.
I implemented a double click Zoom though (C#). You'll need to have the form
capture all key presses to catch the Control key (used to return the chart
to normal view). And a bunch of this code is my custom stuff - but you
should get the picture.


        protected void Zoom(NPlot.Windows.PlotSurface2D ps, int zoomFactor,
int x, int y) {
            try {

                Point minPoint = new Point(0, 0);
                minPoint.X = x - zoomFactor;
                minPoint.Y = y - (int)(zoomFactor / 1.4);

                Point maxPoint = new Point(0, 0);
                maxPoint.X = x + zoomFactor;
                maxPoint.Y = y + (int)(zoomFactor / 1.4);

                ps.CacheAxes();
                ps.PhysicalXAxis1Cache.SetWorldLimitsFromPhysical(minPoint,
maxPoint);
                ps.PhysicalXAxis2Cache.SetWorldLimitsFromPhysical(minPoint,
maxPoint);
                ps.PhysicalYAxis1Cache.SetWorldLimitsFromPhysical(maxPoint,
minPoint);
                ps.PhysicalYAxis2Cache.SetWorldLimitsFromPhysical(maxPoint,
minPoint);
                ps.Invalidate();

            } catch { }
        }


        private void plotSurface_DoubleClick(object sender, EventArgs e) {

            if (controlKeyIsBeingPressed) {
                RedrawAll();
            } else {
                Zoom(plotSurface, 100, ((MouseEventArgs)e).X,
((MouseEventArgs)e).Y);
            }
        }

        private void frmTest_KeyDown(object sender, KeyEventArgs e) {
            if (e.KeyCode == Keys.ControlKey)
                controlKeyIsBeingPressed = true;
            else
                controlKeyIsBeingPressed = false;
        }


        protected void RedrawAll() {

            Charting.DrawChart(plotSurface, chartDataTable, this.Symbol);
            DrawTrendLine(plotSurface, chartDataTable, 21, Color.Red,

[Nplot-devel] Zooming with NPlot

[FXHat - <fxh...@gm...>]

Does anybody use the MouseWheelZoom interaction? Even when I try the demo
application - ABC plot example, I can not zoom in on the graph using my
mouse wheel. This plot does have MouseWheelZoom enabled according to the
source code. Also, is there a way to zoom programatically; i.e. zoom in as a
starting point for the plot so that the user can zoom out if necessary.

Thanks.

[Nplot-devel] barplot not lining up

[dynamix . <dy...@li...>]

I created a barchart based on a few values and in my prog i have an option do change the timeframe. when i look at a short timeframe all is well but when i extend it there are a few items at almost regular intervals where the bottom of the bar is below the zero line.
my ordinate bottom data is all zeros or above so whats up with that ?
also how is it best to handle the width of the bars - as you display a larger amount of data the width needs to shrink.
This is what im doing at the moment : 

 Private Sub callVolume(ByVal igraph As Integer)

        Dim lpvolume As NPlot.BarPlot = New NPlot.BarPlot

        lpvolume.AbscissaData = datedata1
        lpvolume.OrdinateDataTop = volumedata1

        Dim zz, aa, bb As Integer
        bb = volumedata1.Item(0)
        For z = 0 To volumedata1.Count - 1
            zz = volumedata1.Item(z)
            If zz > aa Then
                aa = zz
            ElseIf zz < bb Then
                bb = zz ' get lowest value
            End If
        Next

        Dim zerodata As ArrayList = New ArrayList

        For Each item In datedata1
            zerodata.Add(bb)
        Next

        lpvolume.OrdinateDataBottom = zerodata
        lpvolume.BarWidth = (PlotSurface2D1.Width - 200) / datedata1.Count

        lpvolume.BorderColor = Color.Orange
        lpVolume.Label = "Volume"

        If igraph = 1 Then
            PlotSurface2D2.Add(lpVolume, PlotSurface2D.XAxisPosition.Bottom, PlotSurface2D.YAxisPosition.Right)
        ElseIf igraph = 2 Then
            PlotSurface2D3.Add(lpVolume, PlotSurface2D.XAxisPosition.Bottom, PlotSurface2D.YAxisPosition.Right)
        End If

    End Sub

Re: [Nplot-devel] Samples + website cleanup

[Dennis H. <den...@ya...>]

My offer to convert samples from C# to VB.NET stands for new samples as well as old.

Tangible Solutions has donated a copy of Instant VB to me to convert open source C# project to VB. (they also donated a copy of Instant C# for the reverse, if needed).
Both are great tools that do most or all of the job.

I have in the past used it to convert the entire source of Nplot to VB, with only one glitch were VB.NET lacked security to access one of the XML config files.
Thanks,
Dennis

[Nplot-devel] Samples + website cleanup

[FXHat - <fxh...@gm...>]

I'm willing to help create more C# samples for the website.

I would also suggest a clean up for the website. Half the sections right now
are password protected and have not been updated in ages. The FAQ section
for example could really be improved a lot if it were open for user
contributions. On the other hand, the sections that are open for
contributions are vandalized frequently. Password protecting all sections
and distributing a community password on the mailing list might be a good
solution.

Some sections can also be merged (Bug reports - Submitting patches - Contact
), while others can be removed (History - Unrelated). Last but now least;
the homepage could be a lot more inviting to new users. You could move all
old news to the news section and show a picture or two of NPlot's
capabilities. Also an update for the roadmap would be nice :)

[Nplot-devel] Projects for the new year

[Jamie M. <ja...@sc...>]

Hi everyone...

Some NPlot projects were going to get up and running in the new year...

Dennis Hayes has volunteered to port the current samples to VB.Net
Hywel Thomas has volunteered to start building up unit tests with NUnit

anyone else?

Cheers,

Jamie

Hello NPlot users...

I'm making a new years resolution early this year.

Starting in January I'm going to start investing more time in the  
NPlot project again :-)

One area that is truly lacking is that of documentation and samples.

If anyone is interested in helping out to improve the demo application  
and to get more coding samples up on the website please email me.

I also have a 3-axis plotting and surface plotting project that really  
need to get going... if this is of interested to you please get in  
contact with me.

Happy Holidays.

Jamie
