12.3.8. Canvas¶

Canvas is where the drawing takes place. There is always an active canvas

Axes : Canvas have an implicit coordinate system, and thus, they can have axes

12.3.8.1. Attributes¶

.size: size in the parent space
.coords: if given a system of coordinates
.shape: a clipping shape, so the canvas can take any shape. This annulates .size
.axes: (EXPERIMENTAL) displays or hides a set of two axes
.renderer: allows specification of a renderer to display this canvas.
.vectshader: allows specification of a shader that will process all the lines before rendering?
.subcanvas[i]: if the canvas was partitioned, then subcanvas contain the children canvases
.padding : empty space around the borders. Can be set in percentage or length measure. Image will be clipped to the border
.border : if there is padding defined, this controls how the border is displayed. Its a LineStyle
.xAxis : a reference to the xAxis. If present, the xAxis will be displayed. Axes can be configured (see [axis])
.yAxis : a reference to yAxis. If present, the y axis will be displayed
.xAxis2 : reference to the second xAxis. The second
.yAxis2 : reference to the second yAxis
.wrapping : wrapping

divide: divides the canvas in subcanvases. The function returns an array with the generated canvases. Additionally, those canvases appear in the attribute subcanvases.
- Arguments: a tuple i,j to generate i*j canvases. Can be input in the form “<i>x<j>” or “<i> <j>” or “i j”
- Parameters of divide are:
  - 3x7
  - join: joins two or more subcanvases into one. It can be referred by any of the joined ones
  - widths: allows sepcifying the widths of the columns that generate the subcanvases
  - heights: same for heights
  - border: attributes for the border of the new generated canvases
clone(): clones the canvas
