I can't seem to find out how to change the color of the labels displayed on a ForceDirectedTree bubble.
In all the examples, labels are written in white.
Any help would be greatly appreciated.
Found it :
networkSeries.nodes.template.label.fill = am4core.color("#000000");

I wish to fill the hollow masks in the below binary image. I tried finding contours to fill but didn't work.
Can someone give me some pointers on How to do it?
If you found the contours, they you can just fill the convex poly.
cv2.fillConvexPoly(binary_image, np.array(rect['boundary'], 'int32'), 255)
You will have to adjust this line to work with your own code, but just pass it an index to the contour that you want to fill, and it will fill it with your desired color.
I want to calculate actual height of the text, but the AI is giving the text height using the bounding box dimensions.
Please help me to calculate actual height of text!!
Thanks
This is not possible with SVG. You might have to use a (hidden) <canvas> element, draw the text there and check what pixels were colored. Have e.g. a look at the simple contextBoundingBox() function by Phrogz.
I am using latest flot plugin 0.8 to plot some realtime data.I stuck at following issue
I highlighted point using plot.highlight(series, dataPoint);
Its perfectly working fine.But now I want to change highlight color of already plotted graph.
Is there any way to change highlight point color after plotting flot chart?
Any help would be highly appreciated.
Simply change the series 'highlightColor' option, i.e.
plot.getData()[0].highlightColor = "#f00";
I'm using a bar-chart to add a shaded range of expected values to my graph. The outline of the bars need to be removed to leave only the shaded region. Is this possible?
Thanking you in advance.
I found my own solution...
bars: {lineWidth: 0}
As seen, the default colour in map-view in Gnuplot for zero value is black. I want to make it white and display other colours for other data. May you tell me how to customise the colours please? Thank you.
See the help for palette:
gnuplot> help set palette
After setting the palette, you give for example with points palette to the splot command.
