Hi,
I want to display two series that contain high densitiy sample points of amperage and voltage curve.
Q1:
is it somehow possible to customize the colors of the HighDensityScatterSeries?
Q2:
Is it possible to customize the width of each pixel? (meaning draw an elypse instead a pixel)
Q3:
It doesnt look so nice - the curves made from various pixels.
Actually i would like to use the LineSeries but it is too slow.
I also thought of calculating interpolation data points in order to get enough data point pixels to make it look better.
What do you suggest?

Hi Karl,
By default the XamDataChart provides 5 colors for its series. If you want to change them and set your own colors please looking into the following forum thread :

Currently you cannot customize the points(markers) of the HighDensityScatterSeries.
Let me know if I can assist you with something else on this matter.
Yanko,
in the posts you gave me i read about the XamDataChart.Brushes and the Series.Brush property.
I tried both but it has no effect on the HighDensityScatterSeries.
By default the Series calculates the colors between black and red and it keeps doing although setting the brush/brushes property.
I could not find a special note about the HighDensityScatterSeries in the documents from the post.
I attached an example where i set the brush property. Would be great if you could look into this one.
Hello Karl,
Currently the ‘HighDensityScatterSeries’ is a CTP(Community Technology Preview) in NetAdvantage vol. 12.2 and it seems that we cannot change the brush by using the brushes collection of the XamDataGrid. In our upcoming NetAdvantage vol. 13.1 we are planning to add two more properties for the ‘HighDensityScatterSeries’ : low color and high color that present the two ends of the heat scale.
Let me know, if you need any further assistance on this matter
Great thanks!
The upcoming NetAdvantage vol. 13.1 is planned to be released in the middle of April.
Hello Yanko,
ok i see. I'm not sure if you can help me then. The requirement is to draw a diagram with two lines, each has about 1000-2000 data points. It needs to be updated in realtime. I wanted to use the HighDensityScatterSeries because it's fast enough to do this.
The LineSeries is definitelly to slow. If i want to use use i need to render in a background thread, because it must not block the gui that long. You might know this problem - in wpf its not possible to render a wpf control in background thread. So i need to start a background process and render the HighDensityScatterSeries into a bitmap. It works in general but it's not a very good solution i think.
So you might help me:
- Can you suggest an infragistics control for these requirements?
- May you communicate that there are persons out here, who can not use HighDensityScatterSeries without the heat-color-feature ?
- Will NetAdvantage 13.1 be available till end of Q2-13?
regards,
ps: I'm very pleased by the service of ig. Although i don't have a prior support this time the reaction is really well acceptable.
