Hi Will, Can you post your error so we can look into it? Have not tried 2010 but 2008 should work... Jamie Jamie McQuay Scimatic Software We build software for scientists.

I like the concept for my app and wanted to try it out, but if it won't
compile and you won't provide a pre-built DLL, I may look elsewhere.

Dear Nplot Users, I am looking for a feature to Select a line plot and Highlight it by simply clicking on the plot surface and on the particular line plot. Is this currently possible? If so could someone kindly give me a sample code example? Thank you Sincerely Aalhad |

It has simplified my life a million times over. Second, I am having an issue with the LargeTickStep property of a DateTimeAxis when used in C#. If I set it to anything (other than new TimeSpan(0)) I lose my axis ticks & axis value labels and my axis label is moved above the axis (it is shown under when LargeTickStep is 0). A couple of lines of code: NPlot.DateTimeAxis xAx1 = new NPlot.DateTimeAxis(lstDates[0], lstDates[lstDates.Count - 1]); xAx1.LargeTickStep = new TimeSpan(10,0,0,0); xAx1.TicksLabelAngle = 90.0f; xAx1.TickTextNextToAxis = false; xAx1.FlipTicksLabel = true; graphfrm.m_psGraph.XAxis1 = xAx1; Thanks for your consideration and thanks again for such a great library. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=821568&aid=2900759&group_id=161868 |

Dear Dave,
thank you very much for opening my eyes: I was attaching all data to the
same Y-axis, therefore it could not be plotted in the range.
Greetings,
Thomas

I have two methods (which I see now could be simplified):
protected void DrawIndicatorLineLeft(DataTable sourceDT,
NPlot.Windows.PlotSurface2D plotSurface, string name, string abscissa,
string ordinate, Color color) {
LinePlot trendline = new LinePlot();
trendline.DataSource = sourceDT;
trendline.AbscissaData = abscissa;
trendline.OrdinateData = ordinate;
trendline.Pen = new Pen(color, 1.0f);
trendline.Label = name;
PlotSurface2D.XAxisPosition xp =
PlotSurface2D.XAxisPosition.Bottom;
PlotSurface2D.YAxisPosition yp =
PlotSurface2D.YAxisPosition.Left;
plotSurface.Add(trendline, xp, yp);
}
protected void DrawIndicatorLineRight(DataTable sourceDT,
NPlot.Windows.PlotSurface2D plotSurface, string name, string abscissa,
string ordinate, Color color) {
LinePlot trendline = new LinePlot();
trendline.DataSource = sourceDT;
trendline.AbscissaData = abscissa;
trendline.OrdinateData = ordinate;
trendline.Pen = new Pen(color, 1.0f);
trendline.Label = name;
PlotSurface2D.XAxisPosition xp =
PlotSurface2D.XAxisPosition.Bottom;
PlotSurface2D.YAxisPosition yp =
PlotSurface2D.YAxisPosition.Right;
plotSurface.Add(trendline, xp, yp);
}
But you need to add an additional YAxis:
protected NPlot.Windows.PlotSurface2D AddIndicator(DataTable dt,
string name, string controlKey, string absiscca, string[] lineNames) {
NPlot.Windows.PlotSurface2D indicatorPlot = this.plotSurface;
indicatorPlot.YAxis2 = new LinearAxis();
indicatorPlot.YAxis2.TickTextNextToAxis = false;
indicatorPlot.YAxis2.Label = name;
indicatorPlot.YAxis2.LabelOffset = 30;
indicatorPlot.YAxis2.LabelOffsetAbsolute = true;
indicatorPlot.YAxis2.AutoScaleTicks = true;
foreach (string lineName in lineNames)
DrawIndicatorLineRight(dt, indicatorPlot, name, absiscca,
lineName, Color.Red);
indicatorPlot.Invalidate();
return indicatorPlot;
}
Here's a simple analytic I use:
protected void DrawEMATrendLine(int maPeriods, Color color) {
// generate the trendline
DataTable dt = new DataTable();
Queue queue = new Queue(maPeriods);
DataRow newDr;
double ema = 0d;
dt.Columns.Add("Date", typeof(DateTime));
dt.Columns.Add("EMA", typeof(double));
dt.Columns.Add("Sequence", typeof(int));
queue.Enqueue((double)this.dataTable.Rows[0][4]);
foreach (DataRow dr in this.dataTable.Rows) {
ema = Statistics.GetEMAMeanFromQueue(queue, (double)dr[4],
maPeriods);
newDr = dt.NewRow();
newDr[0] = dr[7];
newDr[1] = ema;
newDr[2] = dr[8];
dt.Rows.Add(newDr);
}
DrawIndicatorLineLeft(dt,
this.charts[hotChartIndex].PlotSurface, "EMA-" + maPeriods, "Sequence",
"EMA", color);
// You could use AddIndicator here
}
And two versions of the MA calc, one weighted and one EMA:
public static double GetEMAMeanFromQueue(Queue queue) {
double total = 0d;
int counter = queue.Count - 1;
int totalPeriods = 0;
foreach (double d in queue) {
total += Math.Abs(d * (queue.Count - counter));
counter--;
totalPeriods += queue.Count - counter;
}
return total / (double)totalPeriods;
}
public static double GetEMAMeanFromQueue(Queue queue, double
currentVal, int maPeriods) {
/// ema% = 2/(queue.Count + 1)
double emaExponent = 2d / (double)(maPeriods + 1);
double yesterdaysEma = (double)queue.Dequeue();
double todaysEma = (currentVal * emaExponent) + (yesterdaysEma *
(1 - emaExponent));
queue.Enqueue(todaysEma);
return todaysEma;
}
The axis are easily the most complex part of nplot - and I still have
trouble with them. It's too bad the original developers haven't take the
time to create good examples of everything you can do with it. Or create
docs that really explore it.
But, once you get over the steep learning curve - it does work quite nicely.

Hey there, is there still anyone of the developers or advanced users around in this mailing list? I am currently at a problem, that if I add two or more linescans to a Plotsurface2D, only the last one is displayed. So, how can I plot more than one XY-dataset?

Dear all, in the example-section of nplot.com I found an example with multiple y-axes. I would like to do something similar (using nplot 0.9.10 stable in VB .Net), showing two sets of data with the same X-data, but different Y-Values and axes. Does anyone have some example sourcecode he could share? Thanks, Thomas -- Dr. Thomas Erichsen Keplerstr. 108 45147 Essen Tel.: +49 (0)162 9436314 |

I am brand new to this list and also to open source development. When using this library, I though it may be useful to update an axis manually. This is especially true for creating small animations (ie continuously updated plots). This can be done by removing the plot, setting updateAxis to true, then adding it again. I thought I would look into adding a function to the plotSurface2D class to force an update of the axis. Is this already done? |
