i have some series that i have not specified any color for them and they are colorized naturally by xtrachart. how can i get the color of each of them when they are drawn in plot control?
i found that the color is stored in actual color property but i cant access it normally and i only can get it in debug mode in watch section.
how can i get the color?
You can utilize the SeriesViewBase.Color Property to specifies the series' color.
code snippet:
((SideBySideBarSeriesView)series.View).FillStyle.FillMode = FillMode.Solid;
((SideBySideBarSeriesView)series.View).Color = Color.Red;
From: How to: Custom Draw Series
You can also implement custom drawing in charts when drawing its
series. To do this you should handle the
ChartControl.CustomDrawSeries event, and then you're able to
change some drawing parameters using its event args.

The answer is here:
get the color of a serie that is colorized naturally
Note that we had need to get the color that was automatically assigned to the series.

In my application, I am using Material 3 for theming. I created a theme at Figma with Material Theme Builder and add generated code to my app. But there is something that I can not figure out how to achieve.
For example, material theme builder creates a Surface tones palette that contains six different colors.
I want to use the "Surface at + 1" color for example, it harmonizes the surface color with the primary color.
But generated code doesn't contain any property like surface1 and harmonizeWith property is not working as expected.
Do you have any suggestions?
Those values are derived within the framework. In case you want to calculate values yourself,
final color = ElevationOverlay.applySurfaceTint(color, surfaceTint, elevation);
Here color would be background color, surfaceTint is defined in colorScheme and elevation would be 1-5. You will get the resultant color.
But...
The way it should be used is by using Material widget as parent with providing MaterialType to that Material Widget.

I have a Packed Bubble dashboard. My Y axis is a list of names and my X axis is a decimal. I want each differing number to be a different color. Can I do this manually?
If you want to color each bubble with a separate color just use the field that each bubble represent in the color shelf. If I understood your data correctly, each bubble basically represents one campaign, so you should use that as the color.
You can manually assign color using Color>Edit Color and assigning the color of your choice.
See image 1.
If you want to color your bubbles based on your measure AVg(NPV/Marketing $) you can do as Alex Blakemore mentioned and use your measure as a stepped color or gradient.
You can use Color>Edit Color here too , in this case manually assigning color is a bit difficult. But if you play with number of steps, the gradient pre-select, etc, you can usually get very close to what ever your wanted it to look like.
Put your numeric field on the color shelf, and either edit the colors to use a stepped set of colors - or change the field to be discrete and choose individual colors to taste.
I am using the 3D Bar chart in FusionCharts. I have displayValues set to display numeric and textual values above the top of the bars. What I would like to be able to do is set the color of individual displayValues differently, for example, if the year-over-year change is positive, color the displayValue for just that bar to green, if it is negative, color it red, etc. Is this possible?
There is no direct way of coloring data plots or data values based on its value. But FusionCharts has an extensive API used to configure Annotations. You can use this API to create texts (data values). Just a rough thought came into my mind.
Using core plot pie chart i am able to produce this. However i want to fill the inside rect with some color is it possible?. i have used same source http://stackoverflow.com/questions/17697300/coreplot-ios-remove-border-line-around-pie-chart..
kindly suggest the other possibilities also.
Make a second pie chart with a radius equal to the inner radius of the ring. Give it a single slice filled with the desired background color.
I would like to set custom color programmatically using the method
[UIColor colorWithRed:(CGFloat)red green:(CGFloat)green blue:(CGFloat)blue alpha:(CGFloat)alpha];
For which i need to know the value of RBG components.
I would like to know is there any way by which i can get the RBG components of a custom color so that i can use them in the above mentioned method.
You can use the DigitalColor Meter.app included with every Mac OS X install. You can find it in ~/Applications/Utilities/DigitalColor Meter.app. Use it to inspect the RGB values of any pixel you mouse over. Once you have the values, you just need to divide them by 255.0 because +colorWithRed:green:blue:alpha: is expecting a floating point value between 0 and 1.
[UIColor colorWithRed:83.0f/255.0f green:217.0f/255.0f blue:58.0f/255.0f alpha:1.0f];
You can use Xcode itself to get RGB value of custom color:
Click the arrow for the Color box and in the resulting dialog box choose others.
And then you can use RGB Slider option to get RGB values
To match a color exactly, there is a great utility called "DigitalColor Meter" located in Applications/Utilities/ that can get the RGB for anything on your screen. Take a screen shot of the color you want to replicate, then use this tool to get the information.
Actually there is no need for using DigitalColor Meter instead we can use the small Search Icon on color picker in the Interface Builder with which we can exactly adjust the color that we like.It is also possible to look up the color values using RBG scales available in it.
