Does the data visualization module support background image especially Surface3D element , also is there any why to apply transparency to plot color. Basically I need to place an image on x-z plane and draw surface plot above it with some transparency, so the user can see the background image through the surface plot.

I'm trying to build a Flower of Life VR example using A-Frame.
The closest thing that I found is using the opacity property in <a-circle>.
Is there a way to create just the border of the circle?
Not sure if it fits your use case but you could use a cylinder with a small height:
https://aframe.io/docs/1.0.0/primitives/a-cylinder.html
Or a tube:

Or just a flat plane with png texture with a circle with transparency
enter image description herePer this page (https://www.highcharts.com/docs/maps/custom-maps) I open inkscape, insert an image I want to draw over and then click on "resize page to selected object" with the image selected. This resizes the page to the size of my background image. I then create the shapes over the image as instructed in the page referenced above. What I want to do is when I paste the svg into the highcharts converter it keeps the shapes as drawn on the page so that I can then insert that same picture into the background of my highchart map on the page and the shapes I have drawn fit perfectly where I drew them on the image in inkscape. Instead it seems like the converter resizes the shapes to best fit the screen. If I didn't want the background image then this would be perfect however with this feature all the images drawn no longer "fit" in the background image where I drew them. Any way to get this to be a 1:1 size conversion so that inserting a background image works?
Does anyone know how to make a 3D line plot where the lines are semi-transparent using Plotly or a different tool?
The 3D plot I am trying to create is here: https://plot.ly/~starhammer/238/
A 2D example of the transparency is here: https://plot.ly/~starhammer/274
This was achieved by adjusting the opacity parameter of the line in Plotly. I have tried changing the line opacity in the 3D plot but it doesn't seem to do anything,
Are you looking for something like this?
If yes, you can adjust your opacity by setting your own 'rgba' color ('a' stands for Alpha and defines the opacity).
From your workspace go to
TRACES => Style
under the Line section, click on the color button and set your desired 'rgba' color
I am new to RRDtool. I generated a graph with grid(--grid-dash 1:0), a LINE(LINE1:rt#4e9a06) and I also have the area between the line and the x-axis coloured (AREA:rt#4e9a06 ). I notice the grid still shows up in the colored-area. I am wondering if there is any way to cover the grid with the colored-area.
Also, I am also wondering if there is any good-looking rrdtool samples/examples available online? Thanks.
I have no way of testing this currently, but here's what the documentation says (emphasis mine) :
[-c|--color COLORTAG#rrggbb[aa]]
Override the default colors for the standard elements of the graph.
The COLORTAG is one of BACK background, CANVAS for the background of
the actual graph, SHADEA for the left and top border, SHADEB for the
right and bottom border, GRID, MGRID for the major grid, FONT for the
color of the font, AXIS for the axis of the graph, FRAME for the line
around the color spots, and finally ARROW for the arrow head pointing
up and forward. Each color is composed out of three hexadecimal
numbers specifying its rgb color component (00 is off, FF is maximum)
of red, green and blue. Optionally you may add another hexadecimal
number specifying the transparency (FF is solid). You may set this
option several times to alter multiple defaults.
What about making an almost transparent grid with arguments like these (note the extra 7F parameter which translates to 127 in decimal):
-c MGRID#<hex triplet>7F -c GRID#<hex triplet>7F
It should still be visible in the background but be invisible (or barely noticeable) once any graph covers it.
Note that this answer from the developer of RRDTool says that the grid is always painted after the graph, so in the end you'll always have it in the foreground, your only solution is to either totally disable it or tinker with color/transparency parameters to make it invisible when covered by the graphed data.
I need to create a chart looking like one shown in the image below using mschart. I can create the half circle using transparent color for the lower half of the doughnut chart, but i am unable to find way to show the needle.
The half circle is 100% and in the image the indicator is on 23%.
Also if there is another way to show the same information with mschart I can change the geography of the chart.
