I m new to chartjs and search a lot and failed to find to create graphs like provide image below
can anyone suggest to me how I can do that?

Problem: I've drawn custom polygons in Mapbox Studio. I am using Mapbox Visual in Power BI and I would like to filter the polygons. I have given the Polygons ID values to differentiate them and to make it easier to filter them later on. I am able to display the custom polygons in Mapbox Visual in Power BI but I am unable to find out how to filter them according to these IDs. I really need help on how I can filter these custom polygons according to the IDs I have given them.
I recently came across a visualization in PowerBI, but cannot find it in the AppSource. Does anyone know how to create this visualization?
According both with The Data Visualisation Catalogue and DataVizProject, this type of visualization is either a Spiral Plot or a Spiral Histogram, as you can see in the image below:
But probably, the example you have provided (created by Net Solutions) adds to the thing sort of a "Ring Plot" with bubbles, so, in essence, we are talking about mixing two kinds of visualization.
As they are a private company charging for its services, my bet is they have done the work in Power BI using a custom visual not publicly available. Nevertheless, you can use this template done in D3.js as starting point, and then, render it in your dashboard.
I'm using a map visualization on power BI. I want to overlap an image on my map with an opacity of 50% (like in photoshop).
Thanks
Are you using the Icon Map? I suggest you download the examples from the Data Stories Galleries. I'd tell you more but I'm just reviewing this stuff myself :-)
I want to train my YOLOV3 with Stanford Drone Dataset but IDK how can do it. Someone has any idea?

You can use AlexeyAB repository to annotate your data accordingly. There is a tool called YOLO_mark there which you can use to draw bounding boxes around objects. In the dataset you mentioned, seems like the data is already annotated. If so, you can use matlab or any other tool to convert the annotation formats to the format of YOLO, which is relative values of each box coordinates:
<object-class> <x_center> <y_center> <width> <height>
I am using the GDAL C++ library to reclassify raster map images and then create an output image of the new data. However when I create the new the new image and open it, the classification values don't seem to have a color defined, so I just get a black image. I can fix this by going into the image properties and setting a color for each of the 10 classification values I'm using, but that is extremely time consuming for the amount of maps and trials I am doing.
My question is, is there a way to set metadata info through the GDAL API to define a color for each classification value? Just the name of the right function would be great, I can figure it out from there.
I have tried this using ArcGIS and QuantumGIS, and both have the same problem. Also the file type I am using is Erdas Imagine (called "HFA" in GDAL).
You can use SetColorTable() method on your raster band. Easiest to do is to fetch one pre-existing raster using GetColorTable(), and pass it to your new raster.
