Teechart with StatsMaster (DewResearch component)

[Oli]

Hi Sandra,

I am using latest Teechart Net version with the latest version of StatsMaster from DewResearch. StatsMaster includes several custom charting styles, which can be used with TeeChart .NET version. I am using the following "Dew charts":
"Dot" plot (Dew.Stats.Tee.DotPlot)
Biplot (Dew.Stats.Tee.BiPlot)
Box Plot (Dew.Stats.Tee.BoxPlot and Dew.Stats.Tee.HorizBoxPlot)

However, I discovered several problems now using the Dew charts:

1) Teechart export the Dew charts with a black background. I have posted this problem earlier without knowing it occur exporting Dew charts. See my earlier post:
http://www.teechart.net/support/viewtop ... ack#p56273

2) Some properties of Dew charts get lost after saving in the Techart native binary format. For example, if I save a boxplot with a solid mean line (boxplot.MeanPen.Style = Drawing2D.DashStyle.Solid) in the binary format, and load it again, the boxplot has dashed lines for the mean. Same problem exist with the median line, and possibly with other properties. Whisker line and colors seems to work fine though. But the bounding box of dotplots are also changed after loading from the binary format.

3) Another problem I found is that the font size of the bottom axis of boxplots is not set correctly. I set a font size of 11 for both the left and bottom axis, but the font of bottom axis is always smaller in the boxplot. However the font size is correct after saving and loading the plot from the binary fomat.


I contacted support of DewResearch regarding the problems, and I have received the following reply:
"As as soon as you use TeeChart format, this wont work with the new version, or there is a high chance that the data wont be compatible. For any errors with what is stored or not, you need to contact Steema. In Delphi there is a an alternative function to save TeeChart state. I thought this was made available for C# also, but it turned out only for TMtxComponent and derived classes. There you can always call: SaveToStream, LoadFromStream or File."

It is very important for me to solve those issues. I purchased DewResearch component in a bundle with Teechart assuming it is fully compatible. I very much hope you can help me.

Hello Oliver,

1) Teechart export the Dew charts with a black background. I have posted this problem earlier without knowing it occur exporting Dew charts. See my earlier post:viewtopic.php?f=4&t=12974&p=56273&hilit=export black#p56273

The export problems are solved in last version of TeeChart.Net and works fine here without DewResearch.

2) Some properties of Dew charts get lost after saving in the Techart native binary format. For example, if I save a boxplot with a solid mean line (boxplot.MeanPen.Style = Drawing2D.DashStyle.Solid) in the binary format, and load it again, the boxplot has dashed lines for the mean. Same problem exist with the median line, and possibly with other properties. Whisker line and colors seems to work fine though. But the bounding box of dotplots are also changed after loading from the binary format.

I can not reproduce your problem here without DewResearch, so export with template and image works fine.

3) Another problem I found is that the font size of the bottom axis of boxplots is not set correctly. I set a font size of 11 for both the left and bottom axis, but the font of bottom axis is always smaller in the boxplot. However the font size is correct after saving and loading the plot from the binary fomat.

It works fine here and we don't find problems with it.

We couldn't check your problems with the assemblies of DewResearch, because we have a problem of compilation with these, but, I inform you, we have contacted with DewResearch to try to solve problems and find a good solution for you, so the last version of TeeChartFor.Net they are using, isn't the last version of TeeChartFor.Net.

Thanks,

Hi Sandra,

Yes, that is right. Only when I use DewResearch I encounter the issues. Everything works fine with charts created without DewResearch. Thanks for looking at it and trying to fix it.

Hi Sandra,

do you have any news regarding the issues with charts produced by DewResearch assememblies?

Thanks

Hello Oli,

I have news of DewResearch developers. They tell me that is possible that the assembly linked to when using DewResearch assemblies is not latest version of TeeChart assembly. For this, I need you check what is the version of TeeChart you are using when you work with DewResearch assemblies. To do it you only need take a look in the folder references, select TeeChart.dll and see in properties its version you are using.

Thanks,

[Oli]

Hi Sandra,

Teechart version I use is 4.1.2012.1032 (Runtime version v2.0.50727). Does it mean whenever I update Teechart.dll, charts produced with Statsmaster may not work properly?

Cheers
Oliver

Hello Oli,

We are talking for this problem with DewReaserch component to find a solution. On the other hand, you need know when you make an application where there is TeeChartFor.Net you only can use one assembly (TeeChart.dll). Therefore, if you use TeeChart.dll of Steema and DewReaserch in the same application, assembly version must be the same, but if you only use one of both assemblies you shouldn't have any problems.

Thanks,

Hi Sandra,
any news from DewResearch? I discovered a several more teechart features which doesn't work with the customized plots using StatsMaster (colorpalette, coloreach, pen properties). I hope for a solution soon as it is crucial for my application development.

Hello Oli,

Sorry for the delay. DewResearch suggest us you contact with DewResearch Team and do next to try to solve the problem:

1.) You makes a small sample project showing problem.
2.) DewResearch Team connects to his computer with TeamViewer and see what the issue is.


Thanks,
