Receives the data will be distributed in every little, the same data to overlay and will change the color to display the number of particles,
This figure is the need to use GDI + to paint, hoping to explain or bosses share resources, to find a lot of also have no idea, novice small white, thank you.

Chart to develop c # and GDI + rendering, coordinate transformation algorithm, real coordinates are mapped to the image coordinates, (x, y, z), (x, y) positioning, z is the density, the corresponding color for rendering, can develop controls or directly generate graphics,

CodePudding user response:

Well, look at the title, I almost can't point to come in,
This you can see the chart support, because it appears that the icon is relatively simple,

If not, then look for third party controls,
Of course, also can GDI rendering,
