20 févr. 2009 · In the initialisation list of the Line constructor, you are assigning Point reference p1 to class member p1, which is a pointer to Point. To get this to compile, you should use Line (Point &p1, Point &p2) : p1 (&p1), p2 (&p2). The same problem occurs in the setpoints method. That shoudl be changed to this->p1 = &p1, etc.
I haven't used Java in a while so I did the solution here in "PARI". Just plug your point's latitude and longitudes into the equations below to get the exact arc lengths and scales in meters per (second of Longitude) and meters per (second of Latitude). I wrote these equations for the free-open-source-mac-pc math program "PARI". You can just ...
6 mars 2016 · Would it be possible to determine the altitude of the target if we know the current point's LLA (lat, lon, alt) and if we know the bearing and distance to the target? With these formulas, it seems like we can gather the target's latitude and longitude, but I haven't yet found anything for altitude. Also, say if we also knew the current point's ...
20 sept. 2017 · 0. These are escape characters which are used to manipulate string. \t Insert a tab in the text at this point. \b Insert a backspace in the text at this point. \n Insert a newline in the text at this point. \r Insert a carriage return in the text at this point. \f Insert a form feed in the text at this point.
So the relationship between the markersize of a line plot and the scatter size argument is the square. In order to produce a scatter marker of the same size as a plot marker of size 10 points you would hence call scatter( .., s=100). import matplotlib.pyplot as plt. fig,ax = plt.subplots()

20 oct. 2008 · To check if a point is within the polygon, get the color of this point from the drawing surface. This is just a O (1) memory fetch. Of course this method is only usable if your drawing surface doesn't have to be huge. If it cannot fit into the GPU memory, this method is slower than doing it on the CPU.
The ggrepel package works great for repelling overlapping text labels away from each other. You can use either geom_label_repel() (draws rectangles around the text) or geom_text_repel() functions. geom_point(color = "blue", size = 3) geom_label_repel(aes(label = Name), box.padding = 0.35,
9 sept. 2018 · Alright, for anyone needing something a little more complicated, here's an extension of @Sheldore's answer on my own data: How to plot the (x, y) text for each point using plt.text(), and handle the first and last points with custom text formatting: Here's the gist of it:
