I'd like to customize a data-defined size legend in QGIS separately from the plotted points in my map for increased legibility, setting the legend fill color to transparent and outline color to black.
I assume that this might be possible to do in the "Legend symbol" option in the print layout, but I cannot access it (see picture) and I'm not quite sure why. The only customization available is for the line connecting circle size and value.
A workaround might be to create a new style in a separate layer, but is there a more direct way to do this in QGIS?
The version I'm using is 3.20.3.

I have a shiny app which displays a geom_bar chart and some text that is displayed in a geom_text subplot. Like so:
All well and good when the screensize is large. But when the screensize is small then the font gets out of hand:
Obviously the geom_bar width has no trouble scaling down to fit in the smaller screen real estate. The text, however, needs some extra help.
I would like to know if there is a way to determine the barwidth in a dynamic plot. If I could find out what the bar width was, then I could scale the font accordingly.
Does anyone know?
I wish to resize the Population label seen in the legend, I want the circle to be smaller than it is right now. How do I do that ?
There are many ways to do this, but the easiest is to set the desired size in the legend. That size will be a manual setting.
plt.legend(markerscale=0.5)
I used to be able to color any Text, shape, or image by just selecting the particular layer and use pain bucket tool for example. Not sure what I clicked, but recently when I try to do the same; I always get the following message:
"This type Layer must be rasterized before proceeding. Its text will
no longer be editable. Rasterize the type? "
I do not want to rasterize. Can I know how to revert back to the normal setup where I can do the coloring without the need for rasterize please.
It also seems to mess around with my selection.
For example - I have a circle shape in the middle with transparent background.
I used to be able to go Select>All followed by Select>Inverse and it will select the circle shape.
But now it selects the entire canvas when I select all but returns the following error when I Select>Inverse
"Warning No Pixels were selected".
You may not be able to color a vector object with paint bucket tool. Instead, can you try using the color option in the blending mode. That will retain the vector property and also apply the color.
The following applies to PS-CS6
In the layers palette,
= Right click on the layer > Blending Options > Select Color Overlay
I am unable to set the label name exact below the bar of bar chart. How to change its origin value to move right side so that it will be exact below of the bar. Please find the image here in this link: i.imgur.com/kJEeM.png
I am search for solution, yet I did not get any solution please help me out of this....
You should use axis labels on the x-axis. There are several example apps included with Core Plot that show how to format dates on the axes. If you already have the text of the labels, you can use custom labels instead. There are examples of that technique, too. The linked image doesn't show an axis line--just set the axis and tick line styles to nil to suppress drawing the axis line.
I'm looking to implement something like the famous "letterpress" effect in my application. Here's what I'm talking about: (just a quick example made in PShop)
As you can see, it looks like it's pressed into the background. I wonder if it's possible to do something like this on the Mac dynamically. Is there a way? Thanks!
You can do the gradient fill portion of the text using the code I provide in this answer. Check the coordinate space first, because I described that for the iPhone, which has an inverted Y axis when compared to the Mac's normal Quartz coordinates.
The text is first used to create a clipping path, and the gradient is drawn within that path.
As far as the internal shadow, you might be able to draw this after the gradient is drawn by using CGContextSetShadowWithColor() with an appropriate downward offset and black color, then drawing the text again using just the stroke of the text. deanWombourne has some sample code for a similar task in his answer here.
Draw the text with a normal font to create a black and white bitmap of the text.
Draw another image that is is the same size and completely filled with the gray-to-white gradient you have above.
Create a completely white image with the same size as your other images.
Draw your back and white text image (1) onto the white image (3) with NSCompositeDestinationOut.
This gives you a white image with your text cut out.
Draw the white image with the text cut out on top of the gradient image and apply a shadow while drawing.
