Created Issue: Need to move horizontal axis with graph [19625]

shambhu1234 — Mon, 22 Apr 2013 04:13:20 GMT

Hi All,
I am displaying a graph with ths xaml code.
====================================================
<Grid>
<d3:ChartPlotter x:Name="chartPlotter">
<d3:ChartPlotter.HorizontalAxis>
<d3:HorizontalDateTimeAxis Name="dateAxis"></d3:HorizontalDateTimeAxis>
</d3:ChartPlotter.HorizontalAxis>
<d3:ChartPlotter.VerticalAxis>
<d3:VerticalIntegerAxis Name="countAxis"></d3:VerticalIntegerAxis>
</d3:ChartPlotter.VerticalAxis>
<d3:Header Content="Weather Information" FontFamily="Verdana"></d3:Header>
<d3:VerticalAxisTitle Content="Count" FontFamily="Verdana"></d3:VerticalAxisTitle>
<d3:HorizontalAxisTitle Content="Date" FontFamily="Verdana"></d3:HorizontalAxisTitle>
</d3:ChartPlotter>
</Grid>
=======================================================
//Object & variables

List<WeatherData> weatherInfoList;
DateTime[] dates;
int[] minTemp;
int[] maxTemp;

On window load start a timer:
---------------------------------------------
private void Window1_Loaded(object sender, RoutedEventArgs e)
{
StartTimer();
}
--------------------------------------------
private void StartTimer()
{

DisplayDynamicDataFromText();
objTimer.Interval = new TimeSpan(0, 0, 1);
objTimer.Tick += new EventHandler(objTimer_Tick);
objTimer.Start();
}
--------------------------------------------------------------
private void DisplayDynamicDataFromText()
{
RemoveOldLine();// Removing all old line from chart

weatherInfoList = LoadWeatherInfo("..\\..\\WeatherRecord.txt");
// loading weather info from txt file to the list of class Wether Info having properties "DateTime","minTemp","MaxTemp"

dates = new DateTime[weatherInfoList.Count];
minTemp = new int[weatherInfoList.Count];
maxTemp = new int[weatherInfoList.Count];

for (int i = 0; i < weatherInfoList.Count; ++i)
{
dates[i] = weatherInfoList[i].date;
minTemp[i] = weatherInfoList[i].minTemp;
maxTemp[i] = weatherInfoList[i].maxTemp;
}

//Get date collection from text file
var datesDataSource = new ObservableDataSource<DateTime>(dates);
//Set date to X-Axis
datesDataSource.SetXMapping(x => dateAxis.ConvertToDouble(x));

//Get number of min and set it to Y-Axis
var numberOpenDataSource = new ObservableDataSource<int>(minTemp);
numberOpenDataSource.SetYMapping(y => y);

compositeDataSource1 = new CompositeDataSource(datesDataSource, numberOpenDataSource);
//CompositeDataSource compositeDataSource2 = new CompositeDataSource(datesDataSource, numberClosedDataSource);

chartPlotter.AddLineGraph(compositeDataSource1,
new Pen(Brushes.Blue, 2),
new CirclePointMarker { Size = 10.0, Fill = Brushes.Red },
new PenDescription("Minimum Temperature"));

chartPlotter.Viewport.FlowDirection = FlowDirection.RightToLeft;
//chartPlotter.Viewport.FitToView();

}

//Upto this point data is showing properly and expected. but on timer event i am inserting new record to txt file for each tick after displaying the current data.

//My requirement is to move the horizontal axis with corrresponding graph on every tick as we insert new record in txt file.

private void objTimer_Tick(object sender, EventArgs e)
{
Int32 intMin = _r.Next(2, 10);
Int32 intMax = _r.Next(30, 50);

DisplayDynamicDataFromText();

File.AppendAllText("..\\..\\WeatherRecord.txt", Environment.NewLine + DateTime.Now.AddYears(tempCount).Date.ToShortDateString() + ":" + intMin + ":" + intMax);
tempCount++;

}

//Suppose for first time txt file have entries
DateTime Min Max
1/1/2010 3 34
1/1/2011 5 44
1/1/2012 6 24
1/1/2013 2 41
1/1/2014 8 40

So for first time x axis should be plotted like

X--------------------------------------------------------------------------------------
*1/1/2010 *1/1/2011 *1/1/2012 *1/1/2013 *1/1/2014

For secode tick we have already added a new entry
DateTime Min Max
1/1/2010 3 34
1/1/2011 5 44
1/1/2012 6 24
1/1/2013 2 41
1/1/2014 8 40
1/1/2015 5 35 new

so this time graph should be

X--------------------------------------------------------------------------------------
*1/1/2011 *1/1/2012 *1/1/2013 *1/1/2014 *1/1/2015

--------like way
X--------------------------------------------------------------------------------------
*1/1/2012 *1/1/2013 *1/1/2014 *1/1/2015 *1/1/2016

-----

---
X--------------------------------------------------------------------------------------
*1/1/2017 *1/1/2018 *1/1/2019 *1/1/2020 *1/1/2021

So overall effect sould be movable from user prospective.

-------------------------------------------------------------------------------------------
Let me know if you have any idea guys!!!!

Thanks

Commented Issue: "Operation could destabilize the runtime" exception after installing Visual Studio 2012 [18738]

thamilton — Wed, 24 Oct 2012 15:30:13 GMT

We have been using DynamicDataDisplay in a Visual Studio 2010 project. After installing Visual Studio 2012 our application is throwing the following runtime exception when trying to instantiate an object that has ChartPlotter as the base class.

"Operation could destabilize the runtime."

Thanks. I do not have AllowPartiallyTrustedCallers in my DDD project.

However, I was able to work around this problem by adding this line to AssemblyInfo.cs in the DDD project:

[assembly: SecurityRules(SecurityRuleSet.Level1, SkipVerificationInFullTrust = true)]

This exception is due to an issue in the .NET Framework 4.5, which was installed with your Visual Studio 2012. See http://elegantcode.com/2012/08/23/net-4-5-operation-could-destabilize-the-runtime-yikes/
In contrast to the example there, for me it helped to uncomment
[assembly: AllowPartiallyTrustedCallers]
in AssemblyInfo.cs of the DDD library, which obviously switched off the CLR verification.

I created a simple WPF test app that has a ChartPlotter on its main form. It also produces the error when built with Platform Target "x86". When built with Platform Target "Any CPU", it runs without error.

My development machine is running 64 bit Windows 7. We target x86 because we have other 32 bit components in our application, and need to target 32 bit OS.

I should clarify that this occurs when we build the application with Visual Studio 2010.

Commented Issue: Dynamic Data Display for Silverlight 2.0 license [16933]

eugenpodaru — Mon, 02 Jul 2012 12:01:01 GMT

The DDD for Silverlight v 2.0 is distributed under MSR-LA license which doesn't allow commercial use. Please vote here if this is an issue for you. High number will raise priority for reconsidering this decision.
Comments: ** Comment from web user: eugenpodaru **

We really like the library and would want to use it our project. The project is an internal tool that will be used by our consultants to sell services to our clients. The problem is that this licence does not allow us to use it. Instead we are using DDD v0.3 which comes with a licence that allows us to use it, but misses some features.

Commented Issue: MarkerGraph doesn't render big X values [18208]

aaabor — Sat, 09 Jun 2012 01:48:27 GMT

I ran into a problem, where my BarGraph doesn't want to render when the X values are in the DateTime.Now range.

The following code illustrates the point:

this.barChart.PlotBars(5, 5); // Will render a big blue bar
this.barChart.PlotBars((double)DateTime.Now.Ticks, 5); //Won't render anything

Non marker graphs, such as LineGraph doesn't have an issue with this.
Comments: ** Comment from web user: aaabor **

Updated with sample to illustrate the point.

Commented Issue: Legend has only one column and hide items that falls below the graph [16444]

sun_dhmn — Sat, 05 May 2012 09:35:24 GMT

Legend has only one column and hide items that falls below the graph.

Legend should resize itself to ensure to show all items. The number of columns should be dynamics to ensure to fit/show all items.
Comments: ** Comment from web user: sun_dhmn **

I also face the same problem.I have one plotter which is drawing graph nicely.But i have two issues with it.
1.)when items count is greater than graph height then it hide the items.Is there any way to add scroll to legend box?
2.)I want to show x-axies with datetime and subgrouped by time. But currently it shows the only date subgrouped by hours.

Created Issue: Support for Metro apps through Portable Class Library [17731]

Thof1 — Fri, 30 Mar 2012 08:34:39 GMT

It would be great to see this library ported to a Portable Class Library so that it can be used in many more project types, including Windows 8 Metro applications.

Is there already any progress in this because there is no free rendering library available yet for Metro applications.

Created Issue: Provide NuGet packages [17664]

davidacoder — Mon, 19 Mar 2012 21:59:59 GMT

Please distribute the binaries for this as NuGet packages, sooo much easier to use in that case and really the way libraries should be distributed these days for .Net.

Created Issue: Bring back WPF support for version 2.0 [17663]

davidacoder — Mon, 19 Mar 2012 21:59:03 GMT

Title says it all. I am much more interested in a WPF version. I use D3 within my scientific code to display data, which of course runs on the full .Net Framework, not Silverlight.

Created Issue: Stretch property of Image for IsolineGraph [17333]

CXgamer — Thu, 02 Feb 2012 08:46:35 GMT

Hi,

I'm using D3 to visualize the efficiency of electromotors. The isoline graph looked like the best solution, as it supports everything I'm planning to do. It currently looks like the attached image.

There are no values for the upper-right corner, yet it is still filled. I'm assuming this is the work of the Stretch property.

I'd like to alter this line of code:
<Image Name="image" d3:ViewportPanel.ViewportBounds="0,0,2,1.5" Stretch="Fill"/>

What other options are there for this?

Thank you in advance,

CX

Created Issue: Setting a DraggablePoint initially at 0,0 means the Draggable point is not visible [17268]

mchilton — Mon, 16 Jan 2012 09:36:18 GMT

Creating a DraggablePoint at 0,0 by any method, xaml or on c# means that the Draggable point is not visible.
e.g. <d3:DraggablePoint Position="0,0"/>

Commented Issue: can D3 draw 1000000 points in a second? [15624]

EricOuellet — Fri, 09 Sep 2011 12:45:46 GMT

Please let me know can D3 draw 1000000 points in a second?
Comments: ** Comment from web user: EricOuellet **

No. By far no, mainly with default settings.
Set RenderOptions.EdgeMode for window containing D3 to remove antialiasing (a lot faster).
Althought anti-aliasing removed, I have really better performance with National Instrument "Measurement Studio" graphics (WinForms).
