I'm using the Telerik Reports graph wizard to create a bar chart. Even though I can change the ColorPalette property to GradientPalette and can choose the desired colors, the results are the same flat single color. What am I doing wrong? Thanks for your help and advice.
The Graph's Color Palette applies gradient coloring on the whole series, not on each of the the data points. I believe you're trying to achieve gradient-colored bars, but this feature is not supported. If in your bar chart you define series groups, then the first bar will be colored using the palette's BeginColor, the last bar will be colored with the palette's EndColor all the bars between them will have solid color, calculated based on their count and offset from the BeginColor towards the EndColor.
The Gradient Palette makes much sense when used in the Choropleth, where the color represents an additional data measure - see a demo here.

I want to display a legend slider besides the map to show the color of the custom raster layer, of the hovered territory. Therefore, I need to get the layer pixel color where the cursor is.
I have found a solution to get the color of a pixel on the map How to get the color of pixels on mapbox, however, if we hover roads or names, another color gets read.
Is there a way to read the layer color on a specific map point?
Are the roads and place labels baked into the raster, or overlaid as vector data sourced layers?
I'm not sure of another method besides querying the canvas, in which case one option would be to hide the vector layers, query, then reshow. But that may not result in the interaction you want?
I have created a sunburst chart with the help of the Anychart library. Now I want to fill different colors on each level. Like blue color background in all slice of level-1. all data is coming dynamically from SQL. How I can do this?Sample image of what I want
Colors of the children in Sunburst chart are inherited from the parent. It means the only way to achieve what you want is to set them for each point in the data. Please check this sample: https://playground.anychart.com/997YGRTI
I make pie chart in SSRS Report
I have 2 Chart and 2 Dataset When I preview My report color not same
this data are same and Data label are same but difference DataSet I want to show in same color
Thank you.
Follow the steps for both pie chart.
You can specify color scheme by selecting the chart and accessing properties.
There you can choose a predefined palette or select "Custom" and define your own color scheme by going to clicking CustomPaletteColors. This gives you more flexibility when working with graphs that have more then one section.
I am new to wpf, I am using wpf toolkit to create pie chart. I have created pie chart using wpf toolkit but my problem is that I have to create Pie chart only with a particular color shade. Say for example green, then my pie chart should use shades of green only. Also this assignment of color to pie pieces should be done pro grammatically.
Can anyone please advice how I go about it?
There isn't a simple answer to your question.
You can set the colors manually, or let the framework pick random ones for you.
What you could do, is have a method that takes as an argument the amount of series in your graph, and a color, and returns an array of colors of that color shade.
You'll have to look at how colors work (RGB) and figure out how you want to do that (keep in mind if you have heaps of series, this will not look good).
Have a look at this colorpicker page for a quick understanding of what you're looking for (in shades).
an example going from dark blue to white will have the following values:
#000000
#00001A
#000033
#00004C
#000066
#000080
#000099
#0000B2
#0000CC
#0000E6
#0000FF
#1919FF
#3333FF
#4D4DFF
#6666FF
#8080FF
#9999FF
#B2B2FF
#CCCCFF
#E6E6FF
#FFFFFF
and it shouldn't be hard to pick from that array 4 shades for example.
Then you'll have to manually (well, with a for loop, but still, in code) add them to your series.
You can use below code in order to change the shades of the charts.
if you want to change from XAML then use this code:
<chartingToolkit:PieSeries x:Name="piecharts"
ItemsSource="{Binding DepartmentwiseGroupedEmployee}"
IndependentValuePath="DeptName"
DependentValuePath="DeptId">
<chartingToolkit:PieSeries.Effect>
<DropShadowEffect ShadowDepth="10" BlurRadius="14" Color="Green"/>
</chartingToolkit:PieSeries.Effect>
</chartingToolkit:PieSeries>
or if you want to change from code then use below code:
var shadowEffect = new DropShadowEffect();
shadowEffect.Color = Colors.Green;
shadowEffect.ShadowDepth = 10;
shadowEffect.BlurRadius = 14;
piecharts.Effect = shadowEffect;
In the silverlight toolkit chart control, the legend on the X Axis can show an indeterminate amount of points. E.g. 1,2,3,4,5.
Would it be possible to colour the virtual columns that this creates? I.e. in the space where legend mark 2 is shown, the space above to the top of the control is shaded to a different colour. This will make it interesting as as the chart scales, the legends on the X Axis change with the size available.
This is mainly for a series of type ScatterSeries for my specific example but could extend to a series of LineSeries.
Hope this explains my requirements.
It's not really possible due to the fact that there are no virtual columns created.
The chart is a canvas and the scatter point is just a point positioned on it. Your best bet would be to create your own ColumnSeries type and then style it to look like a ScatterSeries with your desired background colour.
