Thanks in advance!

Is it normal that outline and LinePen doesn't work if View3D is set to false ?

Hello, I would like to be able to display each line segment of a series with a color proportionnal (example : gray intensity) to a value stored in a matrix. I try to use "Each color" but when I do it, outline doesn't work ! I've seen this post : http://www.teechart.net/support/modules.php?name=Forum...

Ok, I must delete TDownSamplingFunction object in first. And only after do setfunction(NULL). When I zoom, I need a better resolution. I was thinking that put Tolerance to 1 will only display the "average pixel" (with DownSamplingMethod = dsAverage ) on the screen independently of the factor of zoom...

I've try but it doesn't work !

Hello, I've yet an another problem : I don't find how to delete the object TDownSamplingFunction without generate an exeption ! Here is my code : serie = new TAreaSeries((TChart *)Chart); DownSampling = new TDownSamplingFunction((TChart *)Chart); serie_temp = new TAreaSeries((TChart *)Chart); /*====...

Thank you very much, it works!

I'm using C++ Builder 6. I try to to do this : TDownSamplingFunction* DS = new TDownSamplingFunction(Chart); ... but TDownSamplingFunction is an unknow type. Have an idea ? What file should I include ? I don't find the example you've said. The find function in your example application doesn't work f...

Hello, I don't understand why you ask me to use a ColorBand tool... It's just a rectangle, no :? ? I've used a TAreaSerie to solve my problem but I've a lot of point to display (~30000). Is it a way to only draw the point necessary (like the DrawAllPoints property available in TFastLineSerie). Thank...

Thanks for your reply :D! Your method works but I don't want the text . If I set : Chart->Axes->Bottom->Labels = false; The text is not draw but the litte line too :( I saw on an other post that I can use the event OnGetMarkText . So I would like to draw Text on the bottom Axe. When I use CustomDraw...

Sorry,

I've included <math.h> or <Math> but not <Math.hpp>

I test your code but my data are always streched ... maybe it's because I put an offset of 5 pixels on my bottom axe ?

Ok, no problem !
