![]() yThe coordinates are AxesCoordinate System.xThe coordinates are dataCoordinate System,._transform_factory(ax.transData, ax.transAxes)įeatures:Returns a mixed coordinate system Mixed coordinate system (data coordinate system + Axes coordinate system)ģ.1 Sometimes you need mixing dataCoordinate system and AxesCoordinate System。 Because you are AxesThe chart added in may cause problems when the chart is zoomed. So no matter how the graphics are scaled, these TextCan be in the right place.Ģ.3 You can also AxesPass AxesCoordinate System Add some Patch, But it is usually recommended to dataCoordinate SystemAdd under. Of course you can refer to points located outside of this, such as (-0.1,1.1)。Ģ.2 Usually if you need to AxesPlace in Some textExplain, then Generally used AxesThe coordinate system is used for positioning. Axes coordinate systemĢ.1 in AxesIn the coordinate system, (0,0)lie in AxesIn the bottom left corner, (1,1)lie in AxesIn the upper right corner, (0.5,0.5)lie in Axescenter of. transform()The method passes in the coordinates of multiple points at a time, and the output at this time also corresponds to dataA series of coordinates in the coordinate system.ġ.4 When you call ax.set_xlim()or ax.set_ylim()When, the coordinate conversion object will be updated in real time.Īx.ansform((5,0)) # display coordinate array corresponding to data coordinate()Īx.ansform((5,0)) # The point in the same data coordinate system, the display coordinate changes among them pointIs the point displa圜oordinates in the coordinate system (x,y). transform(point)Method will return pointin dataCoordinates in the coordinate system. Call this coordinate inverse conversion object. ![]() ![]() The method returns a Inverse coordinate transformationObject. transform()The method passes in the coordinates of multiple points at a time, and the output at this time also corresponds to displayA series of coordinates in the coordinate system.ġ.3 You can ax.trandDataThe returned coordinate transformation object call. among them pointIs the point dataCoordinates in the coordinate system (x,y). transform(point)Method will return pointin displa圜oordinates in the coordinate system. Call this coordinate transformation object. in fact matplotlibThey are implicitly called to set the data range of the coordinate axis.ġ.2 You can call ax.transDatareturn dataCoordinate system Coordinate conversionObject. The coordinates of the lower left corner are (x_min,y_min), The upper right corner coordinates are (x_max,y_max)。 The user's data coordinate systemġ.1 When calling ax.set_xlimit(x_min,x_max)as well as ax.set_ylimit(y_min,y_max)When the user is established dataCoordinate System. So you have to listen resizeThe incident is very troublesome. Because it fixes the absolute coordinates, causing you resizeYou have to reposition the coordinates while charting. Usually not recommended to use directly displa圜oordinate System. Such as: ax.text(0.05,0.95,label,"This is a Text",transform=ax.transAxes),will TextPlaced on AxesIn the coordinate system (0.05,0.95)Location. In ArtistIn the constructor of transformKeyword parameter (its value is the coordinate conversion object), you can switch the coordinate system. Of course they also have related methods that will come from displayThe coordinates in the coordinate system are converted back to the coordinates in this coordinate system.Ģ. (therefore displayThe coordinate system has no coordinate conversion object). These methods accept input and produce output: the input is a coordinate point in the current coordinate system, and the output is displayThe coordinates in the coordinate system. The coordinate conversion objects of the first three coordinate systems have methods to perform coordinate conversion. ![]() What it shows is displayPixel coordinate system, (0,0)for displayIn the bottom left corner, (width,height)for displayIn the upper right corner.
