I'm working on my QGIS portfolio and doing some training with public geologic data. I used to use MapInfo and would use RGB fields, tie them to the polygons, and make the correct geologic colors. I'm trying this in QGIS and ran into a problem that was asked on StackOverflow years ago but not answered. When I use color_rgb("R", "G", "B") in a Category Symbology, I get the correct colors on the map but not in the legend it created. I've tried the RGB fields as Integer and Text and get the same result, the wrong colors in the legend. I heard that this was possibly a bug in the software and haven't found a work around yet. It would be a pain to have to make the legend manually, that was what the color_rgb was supposed to be for. Does anyone have any work arounds for this issue?

I am playing with candlestick graphs (example from here: https://apexcharts.com/javascript-chart-demos/candlestick-charts/basic/) everything work as expected.
However, I am struggling with adding my signal data for a visual representation of the graph.
I am unable to find a solution that works I was thinking I can somehow fine-tune a timeline - I tried chart.js/apexcharts and for now, I believe the closest will be with the second framework.
What I need is a bar chart that can be used in numeric ranges for the X and Y-axis as presented below. (the goal is to be able to add the green bar as presented)
Is there an easy win or an idea of how to approach this?
Is there something I am missing?
That is my current solution (line graphs with stopWin/stopLose and entry price).
Still suboptimal - but works and is easy to achieve.
After weeks of playing around with it - the solution stayed:
I got two instances of apexcharts one with candlestick and one with line graphs
they are in a single div with CSS playground and position absolute.
I am passing standardised min/max values and has to have the same amount of elements in them (line graphs are allowing You to add null values which allow using this solution.
The final version work is repeatable and looks good.
if you need some help in similar case - feel free to reach out ;)
So I am working on front-end and I am using Ant design library for stacked area charts. Everything else is working quite perfect so far but the text in legend is bit long so it is getting wrapped with ellipsis by default. I have tried alot of options but nothing has worked so far. I want the legend to display all the text and disable word-wrap no matter how long the text is.
NOTE: This is my first ever question on stackoverflow so please feel free to ask for anything which I have missed to mention.
Sorry for the vague title, I have no idea how to really ask this question to be honest so I'll describe what I'm trying to do
I'm attempting to make an app where users can change the colors of different parts of a car. They can change the door for instance to a green as shown, or any other color they wish. They would then be able to change the color of the hood, or the roof, etc.
I've thought about having seperate images for each component and then lining them up to match. However this seems practically impossible when it comes to different screen sizes and scales. I also thought about making a blanket white image, and then creating views over the top with the selected color.
Does anyone have any ideas how I could possibly approach this?
Thankyou
I dont know about the performance of this. But, how about, an overlay of the different parts of the car, but using the same size of the whole car. For example, you have the image of the whole car, and erase all but the door. In other image, you erase all but the hood. If you lay one image above another, it will make the whole car, and the size of the screen will not affect you, because all the images will have the same size.
Then you can use the tint style to change the color of each layer.
My goal is to have a diagram which look like this
Each arrow should be a one dimensional chart, where point are displayed (colors and point size depends on some values)
I'm building my own chart system because I spent a few hours looking for one which allow to custom markers (size and colors, and maybe even shape) but I couldn't find one.
Actually the only one I found is dynamic data display 2.0 which is only proposed in Silverlight.
My biggest problem is the two curving chart I have to do at the top of the diagram.
I tried to use PathListBox control, but because it's a listBox, I couldn't display items at fixed X position (like using a chart).
I'm not asking for a full perfect solution, but can someone give me advices, or clues ?
How would you manage to do something like that ?
It should only be a XAML work here, because all the data are already ready in a ListCollectionView (i'm using MVVM).
Thank you !
Hii
Can anyone tell me how can I show percentage on the piechart....
The percentage is seen on mouseover event but I dont know how to show
the percentage on the piechart's slices....
If you are looking to put labels on the chart itself (instead of tooltip), take a look at this great blog post by WPF guru Bea Stollnitz.
It shows how to do this, in many different modes, and explains not only how, but why.
Take a look at amCharts Bundle for WPF. Pie chart supports labels on the slices, outside connected labels and includes an algorithm to prevent label overlapping.
I've just followed this tutorial (just to make sure) and I get the percentages of each slice as tooltip on mouse over by default.
If you post your code we might be able to spot if there's a problem with it.
You can use labelFunction in mx:PieSeries, and lableFunction look like that
private function pieSeries_labelFunc(item:Object, field:String, index:Number, percentValue:Number):String
{
return StringUtil.substitute("{0} ({1}%)",item.description,percentValue.toFixed(1));
}
Where description is the label that you want to see.
feel free to ask any question.
