SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, and iOS Chart & Android Chart Components
Hello,
I have a line series with 500k to 8 million data points and I use the StrokePaletteProvider to highlight certain peaks in different colors. But the colors only appear right at a certain zoom level, without zooming in it is a mixture of my default line color and the chosen StrokePaletteProvider color. Is there anything I can do about this?
Hi,
I want to implement a chart that represent currency changed rate, so that the chart will show a rise with a green point and a fall with a red point.
in the image I’ve uploaded I’ve used Custom PaletteProvider to manipulate the colors accordingly.
what I want to implement is instead of coloring the Point (Ellipse) I want to load an Image.
the closest i’ve got is to load a single image to all the points, without theme changing (red or green) accordingly.
I did managed to implement that exact behavior in iOS.
how could I implement a dynamically changing Sprits in a PaletteProvider ?
Thanks in advance…,
Been following this doc to color FastLineRenderableSeries datapoints but my series won’t show. Here is my OverrideStrokeColor after implementing the Interface
public Color? OverrideStrokeColor(IRenderableSeries rSeries, int index, IPointMetadata metadata) { ColorMetadata colorMetadata = metadata as ColorMetadata; if(colorMetadata == null) return null; switch (colorMetadata.Color.ToLower().Trim()) { case: blah blah return Colors.blahblah default: return null; } }
And the metadata class
public class ColorMetadata : IPointMetadata { public string Color {get; set; } public ColorMetadata(string color) { Color = color; } public bool IsSelected { get; set; } public event System.ComponentModel.PropertyChangedEventHandler PropertyChanged; }
And the series
<s:FastLineRenderableSeries
Without forgetting (in UserControl.Resources)
<pointColorProvider:ColorPaletteProvider x:
and appending each point with its metadata
like dataSeries.Append(Date, data, new ColorMetadata(“green”));
All works great (without paletteProvider) except when I introduce PaletteProvider=”{StaticResource pointColorProvider}”. Tried with breakpoints in my PaletteProvider class, only OnBeginSeriesDraw gets hit, OverrideStrokeColor is never hit. Please help.?
Hello again!
I’m creating fastlinerenderableseries and I need to show only one part of this line. For this purpose I’m using palette provider. But there is a strange side effect: when I set transparent color for line segment, it also paints lines on the chart (see pictures below-1 before switching on segment painting, 2 – after).
How can I fix it.
Thanks in advance
P.S. I ‘ve also attached project below.
I am using heatmaps in my application and would love to use the same color scheme that is used for those also in my xyz scatter plots. I know how to make palette providers I just don’t know how to get a specific color that is defined by a lineargradientbrush (defined in xaml) for a specific (relative value? 0.0-1.0 ). Is this possible?.
Have a good day!
In the new SciChart version (5th august) I’ve got this result of painting line using palette provider (image 1). Is there any way to make it look like this (image 2)?.
I have a chart with FastImpulseRenderableSeries.
<s:FastImpulseRenderableSeries <s:FastImpulseRenderableSeries.PointMarker> <s:EllipsePointMarker </s:FastImpulseRenderableSeries.PointMarker> </s:FastImpulseRenderableSeries>
The color of each Impulse depends on a own type of each result. There are three different types which should have color green, yellow and red. In the program I use the XyzDataSeries to set the x and y values of the impulse and the z-value as the type to get the color.
var seriesId2 = new XyzDataSeries<double, double, int>(); for (int i = 0; i < SamplePeakList.Count(); i++) { seriesId2.Append(SamplePeakList[i].Mass / 1000, SamplePeakList[i].Intensity, peakType); }
But the IPaletteProvider has no overridable method with x, y and z value!
How can I pass the impulsetype to the palette provider to set the corresponding color?
Hello Everyone,
I am using trial version of Sci Chart. I am interested in using sci chart to build a stock charting program. I would be glad if someone can help me. Though I am using vb.net but you can post code in c# also.
Q-1) How to change the color of a particular candle or wick For e.g how to change color of five candle of my choice. I had used property UpWickColor and UpBodyBrush but it effects all data series.
Thank you,
Cheers,

I want to color individual points in the line. How can it be done with the SciChart?
Attached is an image of what I want to accomplish.
Thanks.
